Solving Unique Challenges with a Hybrid Approach to Insulation

One of the simplest ways to meet building codes requirements in construction is through the effective use of insulation. There are several types of rooftop insulations available in the marketplace, but two of the most commonly accepted in commercial roofing applications are polyisocyanurate (polyiso) and expanded polystyrene (EPS). Polyiso is a lightweight and cost-effective, closed-cell, rigid foam board insulation that provides energy-efficient solutions for buildings in any region and climate, as well as outstanding return on investment and significant energy savings. EPS is a closed-cell, rigid foam insulation manufactured using expandable polystyrene. It is block-molded for most construction applications and is highly customizable, enabling thicknesses up to 40 inches in a single board. EPS is versatile and durable and can provide significant cost and labor advantages. Both polyiso and EPS provide great benefits and R-value in roof construction projects. However, projects often arise when a hybrid solution to insulation may be the most practical. A hybrid polyiso/EPS solution can help you edge out the competition in a number of scenarios. New Construction with Concrete Decks: A recent innovation introduced by Versico is DeckVent EPS Insulation. DeckVent is ideal for new construction projects with structural concrete, lightweight structural concrete, and lightweight insulating concrete roof decks. Using DeckVent in conjunction with one-way and two-way relief vents allows the installation of the roof system to begin upon structural cure of concrete (typically around 28 days). DeckVent is compatible with ballasted, mechanically attached, induction welded, and adhered single-ply roofing systems. The use of DeckVent creates a problem-solving solution for new construction involving concrete decks, enabling construction to commence immediately upon structural cure. Standing Seam Metal Roofs: With square-, taper-, and profile-cut flute-fill products in custom shapes and sizes, a solution is available for all metal retrofit roofs. Combining EPS to fill the metal roof flutes with a subsequent layer of insulation or coverboard can create an ideal foundation for a retrofit roof. Tapered Roof Design: A tapered roof is another ideal candidate for a hybrid approach to save time and money. With thicknesses up to 40" and virtually any slope available in a single board, a base layer of tapered EPS insulation can save nearly 30% in product cost alone, with additional savings on installation time when combined with polyiso. Combining polyiso and EPS in commercial roofing applications is an effective solution that can often save you money and labor on a project. Contact your local Versico representative to learn more.

Roofing with Resilience: A Review of 30-Year EPDM Enhancements

The history of EPDM roofing runs deep. With decades on the market, Versico's EPDM has a proven track record as one of the most resilient membranes in the single-ply roofing industry today. As time goes on and the construction industry evolves, more sustainable structures are becoming the norm. Building codes are increasingly robust and are placing a greater emphasis on protecting your building from Mother Nature’s wrath. Your roof system plays a huge part in achieving compliance and serves as the first line of defense against hail, wind, and other damaging elements. This is where EPDM’s sustainability and durability come into to play. Sustainability and resiliency are some of the strongest attributes of Versico’s EPDM membranes, and EPDM’s durability allows us to offer a high-end, 30-year Total System Warranty that guarantees long-term performance. Below are the enhancements that Versico requires when upgrading to a 30-year EPDM system: 30-Year EPDM Enhancements The Membrane: The thicker and more durable 90-mil non-reinforced EPDM and 75-mil reinforced EPDM are required; fully adhered, mechanically fastened, or ballasted designs are available. The thicker membranes will provide greater long-term performance and superior resistance to weathering. Please note, 45-mil and 60-mil membranes are not eligible for 30-year Total System Warranties. The Splices: Membrane splices are one of most important parts of any roofing system and utilizing our Quick-Applied Tape means more watertight seams and fewer warranty claims. On a 30-year EPDM system, Versico requires membrane with 6”-wide Quick-Applied Tape or 6” Quick-Applied Seam Tape to be installed at all seams and end laps. The 6”-wide tape has greater peel and sheer strength and results in a stronger bond. Please note, 3” factory-applied or hand-applied tape on 30-year warranties must be stripped in with Quick-Applied Cured Coverstrip. The Flashing Details: In addition to seams, flashing details are critical to preventing issues where rooftop penetrations are tied in to the field membrane. On 30-year EPDM systems, Versico requires specific details to be double-wrapped or covered with two layers of flashing. Below is a list of these details: Key U = Universal (applies to all 30-year systems) A = Adhered Systems Only B = Ballasted Systems Only MF = Mechanically Fastened Systems Only  VGC-2.4 QA Seam Tape Splice Intersection (25/30 Year Warranties) VGC-8.1B Pre-Molded Quick-Applied Pipe Seal with 90-mil Membrane or 25/30 Year Warranties VGC-8.3 Field-Fabricated Pipe/Structural Steel Tube Flashing for 25/30 Year Warranties VGC-15.4B Inside Corner Flashing for Projects with 90-mil Membrane or 25/30 Year Warranties VGC-15.8 Outside Corner Flashing for Projects with 90-mil Membrane or 25/30 Year Warranties VGA-2 EPDM Membrane Splices (25/30 Year Warranties) VGB-2.1 Membrane Splice (25/30 Year Warranties) VGMA-2.4 Membrane Splice (25/30 Year Warranties) VGMA-2.5 QA Seam Tape Splice Intersection (25/30 Year Warranties) ***Please speak with a Versico Design Analyst about additional 30-year requirements in regards to adhesives, coverboards, insulation, fastening density, perimeter securement, and metal edging.***     Ryan Ferguson     EPDM Product Specialist     Product Marketing     ryan.ferguson@carlisleccm.com

Making the Choice Between Prefabricated and Shop-fabricated Metal

When it comes to choosing a fascia or coping, the options for colors, finishes, and profiles are virtually endless. Most times, the color and finish will be dictated by the building owner or designer. Roofers and general contractors, on the other hand, often have much more influence over which profile is used and how it’s sourced. This post breaks down the benefits of prefabricated edge metal (such as Versico VersiTrim products) as well as the advantages of shop-fabricated edge metal (made in-house by the roofing contractor or outsourced to a local sheet metal shop). Prefabricated edge metal has a lot to offer, from enhanced performance and code compliance to labor-saving benefits. Below are a few of the advantages of using prefabricated edge metal.  Testing and code compliance: All Versico VersiTrim products are tested to ANSI/SPRI ES-1 standards as required by International Building Code. ES-1 testing has been mandatory for all low-slope roofs since IBC-2003 and using prefabricated VersiTrim ensures that code requirements can be met. The majority of VersiTrim coping and fascia profiles offered by Versico are also approved for use on Factory Mutual-insured buildings or where FM-approved edge flashings are required. Convenience: Using prefabricated VersiTrim products allows contractors to order edge metal and have it shipped directly to the jobsite, with many products available to ship within days. No sheet metal shop is required. On the flip side, roofing contractors who have shops with skilled sheet metal workers can use those resources to work on more complex and profitable sheet metal work, rather than fabricating basic coping and fascia designs. Labor Savings: Unlike traditional gravel stop and drip edge, many VersiTrim profiles have a snap-on design and do not need to be stripped in. This saves considerable labor on the roof and eliminates the need to use primer and cover strip (as is typical with a drip edge or gravel stop). Warranty: All VersiTrim products are covered under the Edge-to-Edge Total Roof System Warranty, offering the building owner protection backed by Versico. While prefabricated edge metal offers many advantages over shop-fabricated edge metal, local fabrication has its own benefits, and shop-fabricated metal is still covered in some Versico warranted roof systems. Here are a few reasons why shop-fabricated edge metal might be a good fit for a project.  Flexibility: While VersiTrim products can be customized, it’s often easier to create complex custom parts locally where the sheet metal fabricator can see what is needed, measure, and fabricate the part. Speed: Many VersiTrim profiles can be shipped in as little as one day; however, if you need something immediately, there’s no substitute for a local sheet metal shop that can fabricate something for installation the same day. Warranty: While VersiTrim will almost always meet warranty requirements, shop-fabricated metal using Versico metal flat sheets can also be included in many warranted roof systems for up to 20 years. For more information, visit the edge metal product page on the Versico website.      Adam Burzynski     TPO Product Manager     Product Marketing     adam.burzynski@carlisleccm.com

TPO and PVC Welding Guidelines

Cold welds are a major concern for any thermoplastic roofing installer. But following a few basic guidelines can go a long way toward ensuring good, long-lasting welds on TPO, PVC, and KEE HP membranes. In this post, we’ll discuss a few best practices that reduce the chances of cold welds and help ensure the watertight integrity of TPO, PVC, and KEE HP single-ply roof systems. 1. Appropriate Equipment Use proper power sources or commercial-grade generators. Generators should be rated for 3,000 watts for two hand welders, or 6,500 watts for one auto-welder. Proper extension cords are critical. For auto-welders, use a 10-gauge wire with a maximum length of 100 feet; for hand welders, use a 12-gauge wire with a maximum length of 100 feet. Welders should be in good shape, with clean air screens and a clean nozzle. 2. Proper Temperatures The following are starting guidelines for temperature, speed, and airflow. Settings may vary depending on membrane thickness (45-, 50-, 60-, or 80-mil). Leister Varimat Temp Speed Airflow TPO 1004°F 12.5 ft/min 100% PVC & KEE HP 1094°F 8.5 ft/min 100% Leister V2   Temp  Speed Airflow TPO 986°F 18 ft/min 90% PVC & KEE HP 1094°F 10.4 ft/min 75% BAK LarOn Temp Speed  Airflow  TPO 1004°F 12.5 ft/min 100% PVC & KEE HP 1094°F 8.5 ft/min 100% 3. Critical Welding Steps Keep in mind that ambient temperatures will affect welding temperatures and speeds, as will welding in the sun versus welding in the shade. Certain substrates can hold heat in the membrane (polyiso insulation), while others can rob the heat from the membrane (concrete). When hand welding, immediately roll across the hot seam at a 45° angle with a 2” silicone roller. This helps to ensure the top membrane is adequately pressed into the bottom membrane. When welding across a step-off, be sure to crease the top membrane into the step-off with a 2” silicone roller immediately after welding. This will help prevent a water channel from forming in the weld. It’s important to perform test welds several times each day because of changing ambient and membrane temperatures. Simply cut a 1”-wide strip across the weld and peel to inspect the weld area. Remember to probe all seams at the end of each work day. 4. Cleaning and Maintenance Always clean aged or dirty membrane before welding. On PVC or KEE HP, use PVC and KEE HP Membrane Cleaner; on TPO, use Weathered Membrane Cleaner. Clean all residue from the weld area and allow it to dry before welding. Maintain your equipment before, during, and after welding. Regularly inspect the silicone pressure wheels on your auto-welder and hand roller to make sure they’re not affecting the integrity of the membrane while welding or rolling. Clean the char off the heat gun nozzle using a brass wire brush and keep the intake free of debris to allow maximum airflow. On the auto-welder, adjust the nozzle to eliminate heel drag. Following these helpful hints will ensure a better installation with fewer cold welds. If you have questions, check out Versico’s TPO and PVC Welding Guides or contact your Field Service Representative.

Avoiding Common Mistakes with Two-Component Low-Rise Adhesives

Two-component low-rise urethane adhesives have become increasingly popular since their introduction to the single-ply roofing industry over 30 years ago. Since 2015, the two-component low-rise urethane adhesive market has significantly expanded with the introduction of new low-pressure dispensing equipment. While low-rise urethane adhesives provide several advantages when designing a roof to withstand extreme weather events, there are common mistakes that can affect the application of the product. Below are common mistakes that can occur during two-component urethane adhesive applications: 1. Gaps between the deck and wall/penetration that are not sealed: Unsealed gaps allow humid air to enter the roofing assembly and condensate on the deck, weakening the insulation facer. A physical air block using foam or a backer rod in addition to VapAir Seal 725TR or Pressure-Sensitive Flashing is required. 2. Loose material or moisture on the deck: Dirt, dust, debris, and loose felts will compromise the adhesive bond. After brooming, use a blower to remove any residual contamination. Deck must be dry. 3. Un-weathered asphalt wasn’t primed: Versico requires the use of CAV-GRIP® 3V or 702 Primer over weathered asphalt when beads are spaced at 4”, 6", or 12" o.c.. Adhesion to un-weathered asphalt is doubled with CAV-GRIP 3V or 702 Primer, with CAV-GRIP 3V being the preferred method. Fastening the first layer of insulation is an option. 4. Depressions in the deck not accounted for: Hard insulation boards will bridge depressions or deflections in the deck. These areas should be marked ahead of time so that more adhesive or thicker adhesive can be applied to compensate. 5. Pencil-thin beads applied: Proper application and performance requires a minimum ½"-wide wet bead of adhesive that will foam out to around 1” to 1½”. 6. Bead spacing exceeds specification: Bead spacing has a direct impact on the uplift performance of the assembly. If the spec calls for 6" o.c. and adhesive is applied at 8" or 9" o.c., the ultimate uplift strength will be reduced. A 4" o.c. spacing requires 12 beads per 4' x 4' board. A 6" o.c. spacing requires 8 beads per 4' x 4' board. A 12" o.c. spacing requires 4 beads per 4' x 4' board. (Maximum 4' x 4' insulation boards when adhesive is extruded at 12" o.c. or when boards exceed 4" thickness, or 4' x 8' insulation boards when adhesive is applied in full spray, 4", or 6" beads.) 7. 12" bead spacing used in corners and perimeters: Corners and perimeters experience more wind uplift pressure, which is why Versico requires tighter bead spacing in these areas. 12" bead spacing is not acceptable in corners or perimeters. Know the spacing requirements prior to starting the job. 8. Thin application over gravel BUR: A thicker application of adhesive is required over a properly prepared gravel BUR. The foam must rise 3/8" above the remaining gravel, or it won’t touch the board. 9. Not waiting for “string/gel” time: If insulation boards are set prior to the adhesive reaching string- or gel-like consistency, the foam cells collapse back to a liquid and the adhesive loses a significant amount of its holding power. This is very important to note. 10. No weighted roller used, and no relief cuts or constant weight applied: Rigid insulation boards must be forced into the adhesive with a 150-lb. segmented weighted roller. Relief cuts and constant weight are sometimes required to promote a solid bond. Rolling the boards at the 5-minute mark allows adhesive to gain strength. 11. Not changing static mixing tips: When the Part-A side and Part-B side of 2-component urethane adhesives are mixed together, it creates a thermal reaction that produces the adhesive. The adhesive in small static mixing tips will begin to solidify after 15-20 seconds, meaning the tips must be changed to avoid off-ratio or clogged guns. 12. Not shaking Dual Tanks: Dual Tanks use a propellant to disperse the adhesive. To activate the propellant, the tanks must be shaken for 30 seconds prior to using. When the tanks are not agitated, the adhesive will not disperse properly, reducing coverage rates or producing off-ratio adhesive. 13. Cold or hot adhesive: Keeping adhesive at the recommended temperatures is important to ensure proper performance. Adhesives that are too cold or too hot will affect coverage rates and the performance of the adhesive. During winter applications, hot boxes and heated blankets should be used to keep the material between 70°F and 90°F.

CAV-GRIP 3V Dos and Don'ts

CAV-GRIP® 3V Low-VOC Adhesive is an optimal choice when you’re installing fully adhered EPDM or TPO roofing systems. This low-odor adhesive requires minimal setup time, dries fast, and can be applied quickly and accurately. Plus, its long “open time” makes it a prime candidate for projects utilizing larger sheets. Like anything else, there are dos and don’ts associated with using CAV-GRIP 3V. Check out these guidelines to ensure a proper, headache-free installation. Do Keep replacement tips handy – CAV-GRIP 3V spray guns have brass tips which achieve the optimal spray pattern. However, a clogged or damaged tip can negatively affect spray capabilities and result in wasted adhesive. To ensure that a damaged tip won’t delay your progress, it’s a good idea keep a bag of replacement tips handy. Use a splitter – Consider using a splitter if you’re working with the larger 85 lb. cylinders. Splitters allow you to attach two hoses to one tank, which can double productivity. Store properly – Store CAV-GRIP 3V cylinders in a protected, conditioned space with temperatures above 70°F prior to and during application. If CAV-GRIP is stored below the 70-degree mark, you’ll have to wait for it to warm up before application. If a cylinder is below the minimum temperature, it will produce an intermittent spray or “sputter” when it is used. TIP: try warming the product up before checking to see if your gun or hose are clogged. Secure all cylinders – Make sure you properly secure cylinders (regardless of whether they’re full, partially full, or empty) so they can’t roll off the roof. Use the right gun for the situation – The CAV-GRIP 3V Spray Gun with Extension Wand is perfect for wide-open roof areas, while the regular CAV-GRIP 3V Spray Gun (without the extension wand) is ideal for tight or confined areas. Keep the gun moving – Keep the spray gun moving while you’re spraying the adhesive to avoid thick or puddled areas. Adjust your technique if necessary – While you’re spraying, you may need to adjust the distance between the gun and the substrate to attain the proper coverage rate. In windy conditions, control the amount of trigger pull to ensure a proper web pattern is achieved and to prevent adhesive from being blown away. Clean up – You can reuse your guns and hoses over and over again if you keep them clean. First, completely depressurize the cylinder. Disconnect the gun and hose assembly and immediately attach it to a canister of Low-VOC UN-TACK™. Pull the trigger and allow the UN-TACK to flow through the hose and gun for five to ten seconds, or until the liquid coming out is clear. Depressurize the UN-TACK, remove the assembly, and store for future use. Don’t Don’t wipe adhesive off the spray tip – Immediately after spraying CAV-GRIP 3V, you may see adhesive buildup on the tip of the spray gun. The installer’s first reaction is often to wipe away this residue with a rag; however, doing this forces cured adhesive back into the tip orifice, leading to improper spray patterns and ultimately a clogged gun. Instead, allow the adhesive to thicken on the tip and peel away the buildup when you’re ready to spray again. Don’t shake – Unlike Versico’s Flexible DASH™ Dual Tank Adhesive, you do not need to shake the CAV-GRIP cylinder prior to application. Shaking the cylinder will disrupt the adhesive and result in the loss of propellant, which is vital to achieving the expected 1,000 ft2 coverage rate per cylinder in a two-sided application. Don’t tilt – Don’t tilt the cylinder or lay it on its side while applying adhesive. Doing so will result in air pockets within the gun and hose assembly which could affect the spray pattern and reduce your coverage rate. Don’t mishandle – CAV-GRIP cylinders are pressured tanks and must be handled with care. Treat cylinders more like a propane torch set and less like a pail of standard bonding adhesive, both on and off the jobsite. Don’t overspray – Don’t apply adhesive to splices to be hot-air welded or areas where primer and pressure-sensitive tape will be applied. If overspray occurs, use Weathered Membrane Cleaner or commercial-grade duct tape to remove it. Don’t install membrane too soon – Don’t install membrane over wet or puddled CAV-GRIP 3V. Doing so will trap solvents between the membrane and substrate, causing “solvent bubbles”. Allow the adhesive about three to five minutes to set up, or become tacky, before installing membrane. Don’t use band heaters in cold weather – Band heaters can reach temperatures of more than 400°F, which can cause over-pressurization inside the cylinder and lead to a valve failure and loss of product. Instead, try power-heated blankets and/or hot boxes when necessary. Don’t let a disconnected hose sit around – Adhesive can cure inside the hose or gun, causing it to sputter or become blocked. When switching a hose and gun assembly from one cylinder to another, make sure both cylinders are sitting side-by-side during the change. Shut the empty tank off, point the wand into a trash bag, and pull the trigger to empty all excess adhesive out of the hose and gun. Then, unhook the hose from the empty tank and immediately hook it up to a new cylinder. Don’t punch a hole through the side of the tank when the tank is under pressure – Once the hose is removed, open the tank back up slightly to relieve excess pressure. From there, punch a hole through the designated area and properly dispose of the tank.

Welding TPO and PVC Coated Metal

Welding Versico’s coated metal is quick and easy if you follow a few simple guidelines. Here are some useful tips for your next VersiWeld® TPO or VersiFlex™ PVC Coated Metal installation.  Product facts Description: 24-gauge hot-dipped G90 galvanized steel sheeting with a layer of 35-mil non-reinforced TPO or PVC flashing laminated to one side Size: 4’ by 10’ Packaging: 10 or 25 sheets per pallet Standard colors: TPO – White, Tan, Gray, Bronze, Patina Green, Rock Brown, Terra Cotta, Slate Gray PVC – White, Tan, Gray Markings: The underside of each coated metal sheet is marked with “TPO” or “PVC”; these markings are repeated several times to avoid misidentification Shelf life: None IMPORTANT: TPO and PVC are not interchangeable and will not weld to each other Before you begin It is essential that the material is clean. The flat sheet goes through a few processes at the contractor’s metal shop, including shearing and breaking. When the metal is formed, it picks up dirt and contaminants that can negatively affect its weldability. The most common error associated with hot-air welding coated metal is the lack of proper cleaning. After the coated metal profiles are fastened into place on the roof and before you begin welding, clean with Weathered Membrane Cleaner (for TPO) or PVC and KEE HP Membrane Cleaner (for PVC and KEE HP). Pour the appropriate cleaner from a safety can onto an HP Splice Wipe or other natural fiber rag; then, wipe the metal with the wet cloth to make sure the entire area is clean. If there’s a heavy buildup of dirt, you may need to use a Primer Pad to remove it. When working with cleaners, remember to wear appropriate personal protective equipment, including safety glasses and permeation-resistant gloves that meet ANSI/ISEA 105-2005. Make sure the underside of the membrane being welded to the coated metal is also cleaned. Allow at least 10 to 15 minutes for the solvents in the cleaner to flash off the surfaces you’ll be welding. Heat welder setup When setting up your heat welder, you must consider the thickness of the membrane you’re welding to the coated metal. An 80-mil membrane will require more heat than a 45- or 50-mil membrane. Start the process with the hand welder at the number 7 or 8 setting. Because the 35-mil TPO or PVC film is laminated to the metal, it remains robust during the welding process and will accept more heat without distortion. Welding coated metal to membrane Start the welding process by building an air dam parallel to the rear edge of the metal. This will trap the heat and ensure it isn’t lost under the membrane. Using a hand welder and a 2” neoprene roller, weld the membrane to the coated metal, then roll in a perpendicular motion. Check your welds To check for proper fusion, weld a strip of membrane to a scrap piece of coated metal. Once your weld has cooled, pull the membrane until failure. Proper fusion has occurred if the membrane delaminates from itself, leaving the bottom ply welded to the film, or if the membrane tears when you try to pull it off the coated metal. For more information on securement requirements and instructions on how to address metal end joints, follow detail TPC-1.2.

Quick-Applied Flashing Options for Every Detail

Versico offers three different types of VersiGard® EPDM Quick-Applied (QA) Flashings to tackle the variety of details found on any given roof. All three feature the proven weatherability of EPDM and come with 30-mil of QA seam tape to create a watertight seal. The primary difference among the three is the amount of cure in the rubber, and the process used to manufacture them. QA Uncured EPDM Flashing is used to flash irregularly-shaped objects or details with multiple angle changes. The uncured state of the flashing allows the rubber to be formed and stretched into place without reverting to its original shape, like cured rubber. The flashing formulation is designed to cure on the roof with exposure to heat. Since we need to limit heat exposure in the manufacturing process to keep the product uncured, we require all edges to be lap sealed. This is to keep water from getting between the flashing ply and the tape ply while the material cures on the roof. T-joints, corners, and pockets are all made from uncured flashing; which has a 9-month shelf life. QA Overlayment Strip – often called “semi-cured” flashing – utilizes the same uncured flashing formulation, but is semi-cured with heat during the manufacturing process. The overlayment strip has the dark black look of uncured flashing, but is 70% cured to add tear resistance for stripping in metal edging or end laps. QA Overlayment Strip is packaged without the diamond pattern film as it is removed during the semi-curing process. This gives you an easy way to tell the difference between a roll of QA Uncured Flashing and QA Semi-Cured Flashing. Due to the semi-cured nature of QA Overlayment Strip, it can seal step-offs at splice intersections of 60-mil rubber without the need for T-joint covers. QA Overlayment Strip is better suited to strip-in seams than QA Uncured EPDM Flashing, as you can eliminate the need for lap sealant and T-joints. QA Cured Cover Strip is made with the same 60-mil non-reinforced membrane as our standard sheeting, and is then laminated to 30-mil of QA seam tape. This product is primarily used for stripping-in metal or end-laps, and offers the same finished appearance as the field membrane. Due to the fully-cured nature and thickness of the product, T-joints are required at splice intersections. VersiGard White EPDM Peel & Stick Flashing is available in uncured flashing and cured cover strip options; and is approved for use on both EPDM and TPO roofing systems. VersiGard’s White EPDM Peel & Stick Uncured Flashing has a more aggressive cure package to account for the fact that the white flashing will not gain as much heat naturally on the roof. This translates into a shorter shelf life of 6 months. Keeping your white or black uncured flashings cool during long term storage will help you to maximize its shelf life. Versico has all your flashing needs covered.

CAV-GRIP 3V vs. Traditional Bonding Adhesive

With the introduction of Versico’s CAV-GRIP™ 3V Adhesive, it’s faster than ever to install fully adhered TPO and EPDM. CAV-GRIP 3V can be used to adhere standard TPO and EPDM membranes in weather conditions down to 25°F, with a much faster application rate and flash-off time than traditional bonding adhesive. Check out this time trial video for proof, and use the tips below to ensure maximum speed and efficiency. Here are some keys to saving time and getting a the most out of CAV-GRIP 3V: Use larger cylinders and hose splitters: CAV-GRIP 3V comes in two sizes -- 85lb. and 40lb. cylinders. Using 85lb. cylinders allows for more coverage without having to change tanks. By using a hose splitter, two people can spray CAV-GRIP 3V from one tank at the same time, allowing for faster application. Keep cylinders warm in cold weather: As CAV-GRIP 3V cylinders get cold, the coverage rate will be reduced and application will become more difficult. Store cylinders inside or in a hot-box at 70-80°Fbefore use. It is also important not to set cylinders directly on a metal deck, as this will accelerate heat loss. Instead, always set the cylinder on insulation and use a Power Blanket to keep it warm during application. Overlap is key: When applying CAV-GRIP 3V to adhere EPDM or TPO in the field of the roof, very little overlap is required. While spraying, try to overlap 1-2 inches to ensure 100% coverage on the back of the sheet and the substrate. However, when using CAV-GRIP 3V to adhere membranes to walls, it is important to overlap 50% when spraying. Use CAV-GRIP 3V and these tips to save a ton of time and labor on the roof. Time previously used to be spent stirring, rolling, and waiting for adhesive to flash off can now be spent laying more squares of roof to get on to the next job more quickly. For more information on CAV-GRIP 3V, please visit our Labor Saver page or reach out to Adam Burzynski with further questions.     Adam Burzynski     TPO Product Manager     Product Marketing     adam.burzynski@carlisleccm.com

Achieve the Look of a Metal Roof Using New TPO Colors and Contour Rib

The VersiWeld® TPO Rib Profile is a great way to achieve a standing seam metal roof look on sloped roofs or mansards. VersiWeld TPO membrane and the rib profile are now stocked – with no minimum order quantities -- in five special colors in addition to the standard white, gray, and tan options. This makes it even easier to satisfy a building owner’s desire for an aesthetically pleasing standing seam look using TPO. When using special color TPO and rib profile, an owner will be judging the finished roof on its looks, in addition to its performance. It’s important to ensure proper spacing and alignment, and consider where membrane splices will fall when installing the rib profile. Here are some easy tips to follow on your next rib profile job: “Measure twice, cut once”: Similar to the old carpenter’s saying, check your measurements before you start the job. Prior to installing any rib profiles, measure the spacing for the ribs on the roof to ensure they are spaced properly. If possible, try to align the edge of a rib profile with a splice in the membrane to hide seams. Use a jig or pan to make spacing easy: Once the spacing has been determined, lay out a few ribs on the ground and position the automatic welder as if the rib is being welded. Then measure the space between the edge of the welder and the next rib. This dimension can be used to fabricate a metal pan ensure proper alignment and spacing of the ribs. The first rib is critical: Always chalk a line to position and install the first rib. Align the edge of the rib with the chalk line and tack-weld it every 6” to ensure it is perfectly straight and stays in place. If done properly, the first rib can act as a guide to align the next rib using the metal spacing pan. It’s important to ensure that after the first rib has been tack welded for positioning purposes, you fully weld it for permanent installation. Use heat to hold rib profile pieces together: To reduce separation of connected rib profile pieces during the welding process, use a hand welder to heat the end of one of the rib profiles after inserting the connector pin and push the two ends together. This will help eliminate small gaps between rib profile pieces. VersiWeld TPO special colors and rib profiles can give a building the look of a metal roof, with the fast installation and proven performance of TPO. Refer to the Rib Profile Installation Guide for more great tips to make sure your next Special Color Rib Profile installation is a success.     Adam Burzynski     TPO Product Manager     Product Marketing     adam.burzynski@carlisleccm.com

Storing Your Materials During Inclement Weather

When storing roofing materials prior to install, it is important to remember most roofing materials are not designed to be stored in cold or inclement weather conditions; especially when ambient temperatures dip below 40°F. Membranes, adhesives, equipment, and contractors will perform differently in colder or inclement weather - so planning and considering how the inclement weather will impact material storage, installation time, and quality is critical. Membrane: Storing roofing membranes at your job site during warm months is straightforward: keep the rolls off the ground (on pallets), and protect them from moisture by using breathable, waterproof tarpaulins. In inclement weather, temperatures grow colder - the dew point and temperature come closer together; increasing the potential for condensation and frost forming on materials; and storms/winds become more frequent. Keep roofing materials warm and dry by storing them inside a conditioned space or in a heated job trailer. Keeping materials warm and dry will reduce the risk of moisture being introduced into the roof system during construction, and minimize the possibility of deficiencies in the completed roof system. In addition, material rolls will become more rigid as they get colder, requiring additional time to kick out and relax the membrane before installing. In wet or windy conditions, make sure the roof membrane rolls are covered with a breathable-waterproof tarp and that the tarpaulins are secured to prevent wind damage and/or displacement such as with a pallet or bands. Please note that flashings must be heated prior to application, regardless of the season. When these products are heated until warm to the touch, they will be much easier to install, particularly when flashing corners and irregular shapes. Adhesives/Pressure Sensitive Products: When dealing with membrane adhesives, there are generally two main categories to consider: solvent-based and waterborne adhesives. Recently, the use of waterborne adhesives has been growing steadily because of low-odor and VOC code requirements. Both types of adhesives have similar manufacturer recommendations for storage temperature, typically between 60° and 80°F. Adhesives, primers, or pressure-sensitive products can be stored at temperatures below 60°F but must be restored to between 60°-80°F prior to application for best results. When ambient temperatures are expected to fall below 40°F for an extended period, a heated enclosure or hot box is strongly recommended for jobsite storage. This applies to pressure-sensitive products as well. Insulation: Polyisocyanurate or polystyrene insulation is typically shipped protected by a plastic wrap, plastic bag, or both. This factory packaging is intended for handling the polyisocyanurate in the manufacturing plant and during transit; it should not be relied upon as protection at jobsites or other outdoor storage locations, unless specified otherwise by the manufacturer. To ensure your insulation is properly protected in inclement weather, follow these steps: Store bundles flat and upright with the bottom of the bundles elevated (2” or more) above a finished surface - preferably gravel, pavement, or concrete - rather than on dirt or grass. Slit the bundle packaging vertically down the center of the two short sides to prevent moisture accumulation within the package. Completely cover the bundle with a waterproof tarp and secure to prevent wind damage and/or displacement, such as a pallet. If you follow the steps outlined above for your roofing material storage, it will increase the success and longevity of your installation.

Our PVC Pressure-Sensitive Cover Strip is a Specialized Solution

In the past, your metal edge options on a PVC roof were extremely limited. You had a choice of white, gray, or tan coated metal before you would be required to step up to an expensive two-piece metal edge system. This is no longer the case! With the introduction of Versico’s VersiFlex™ PVC Pressure-Sensitive (PS) Cover Strip, the building owner or architect can now use any color Kynar-coated metal they choose. The installation process for PVC PS Cover Strip looks like this: Apply the PVC Step 1 Activator to the membrane surface with a roller. The Activator is the first of two primer steps, which prepare the membrane to accept the pressure-sensitive cover strip. Once the Activator has completely flashed-off the, Step 2 Primer can be applied. The primer should cover both the Activator and the metal when applied. The third and final step is to install the pressure-sensitive cover strip, after the primer has flashed-off. Unroll a few feet, pull the release liner, and place the cover strip onto the previously-primed surface. Use a hand roller to adhere the strip to the membrane. Use of the VersiFlex PVC Pressure-Sensitive Cover Strip will save you money, labor, and time on the roof. Utilize this specialized solution product on your current or future PVC roofing job, and experience what contractors have been calling a “game changer.” To learn more, view the installation guide or visit the Specialized Solutions page.

Cold Weather’s Effect on Flexible DASH Dual Tank Adhesives

Maintaining the proper storage and installation temperature of Versico Flexible DASH roofing adhesive materials will improve the string time/rise time and will also assist in achieving the proper viscosity of the materials; which in turn will help to increase yield/coverage of your Flexible DASH materials. Problem: When working in the states highlighted below, you will need to pay attention to the average daily temperatures in relation to the storage and installation of Versico Flexible DASH adhesives. Here is a simple explanation of viscosity: Viscosity is a complicated and sometimes confusing topic, and understanding how to lower viscosity is a challenge during cold winter months. A fluid that is viscous will be thick, sticky, and semifluid in consistency. You can lower viscosity by adding friction and/or increasing temperature. In short, the warmer the material, the thinner the fluid - meaning less friction and increased material flow. Proper material temperatures can also affect the performance of the adhesive. When material temperatures are below the recommended levels, the adhesive cannot properly mix due to the increase viscosity. It is always important to keep your adhesives stored and applied at the temperatures recommended by the manufacturer. Versico’s Temperature Storage and Application Recommendations Flexible DASH Bulk and Dual Tank Do not store at temperatures above 100°F or below 50°F. Kits stored below 70°F must be given time for the internal material temperature to warm up to 70°F prior to use. When storing or using adhesives in temperatures below 40°F, the adhesive internal temperature must be returned to 70°F prior to use. Placing adhesive in a heated area (70-90°F) for 4 hours should allow liquid adhesive to reach 70-90°F. In colder temperatures, it is recommended to utilize heated blankets to ensure the tanks are kept warm while dispensing the product. Solution: In the winter months, proper material temperatures become imperative. Regardless of the urethane adhesive (DASH or Flexible DASH), material temperatures at the time of installation should be 70°F or rising. When temperatures fall below 70°F, urethane adhesives can experience mixture ratio issues. The use of heated blankets or hot boxes should be used to keep material temperatures above 70°F. Heated blankets make it easy to lower the viscosity of Versico’s Flexible DASH Dual Tank adhesives. Heated blankets come in various ready-to-ship products, including dual tank and single tank adhesive offerings, and pallet blankets. If you need help with material storage or viscosity reduction, Versico has you covered. Contact your local Versico representative for more information. Versico has partnered with two equipment manufactures that provide heated blankets. For more information, contact 4C’s Spray Equipment, Amped Equipment, or Advanced Roofing Innovations (ARI). Heated Blanket Viscosity-Improving Products: Flexible FAST Frequently Asked Questions Q: How long will it take a heated blanket to warm a cold tank? A: Tanks can take anywhere from 4-8 hours to heat back up to the proper application temperature. Q: Can I use a heated band to warm tank or cylinder products? A: No -under no circumstances should you use a heated band product with a pressurized tank (Dual Tanks or CAV-GRIP™ 3V). Heater bands can reach temperatures of 300°F – 400°F, which will overheat the tank and cause it to explode. Q: Are heated blankets safe to use with Dual Tanks? A: Yes, heated blankets have a regulated temperature of 80°F - 100°F and are designed to work with pressurized tanks.

Approved Ice and Snow Melts for use on EPDM Membrane

Keeping a roof in top-notch shape during the winter is of the utmost importance to building owners and applicators alike –keeping your crew safe and upholding the integrity of the roofing materials is essential. One of the most commonly asked questions about an EPDM roofing system in the winter is related to the chemical compatibility of rock salt and other ice melts with EPDM membrane.  EPDM is chemically resistant to rock salt (also known as halite or sodium chloride) and calcium chloride.  If either of these two materials are applied according to the suppliers’ recommendation on an EPDM roof, there will be no chemical deterioration of the membrane. Your biggest concern with rock salt and calcium chloride pellets will be the physical form these ice melts come in.  Rock salt is a hard, crystalline product that could harm the membrane if walked on after application.  Calcium chloride pellets are somewhat softer in texture, but could still potentially cause damage to the membrane if walked on before being broken down from the pellet form.  Because of this, it is wise for you to limit foot traffic over any areas where ice melts have been applied, in order to minimize the potential for membrane damage through abrasion or puncture. You should also note that chemicals such as halite or sodium chloride can potentially cause corrosion to metals like aluminum or copper, so it is wise to avoid application of these chemicals around any area on the roof that is made of these materials. For more information regarding installation, care, and upkeep of EPDM – please contact Ron Goodman.     Ron Goodman     EPDM Product Manager     Product Marketing     ron.goodman@carlisleccm.com

IRE 2019: Education and New Products Take the Spotlight

Approximately 10 years ago, the marketing community was declaring conventions and tradeshows a dying industry. However, after attending the 2019 International Roofing Expo (IRE) in Nashville, Tennessee, last month, this notion has not infiltrated the roofing industry. With more than 14,000 attendees and nearly 500 exhibiting companies, the roofing industry certainly supports tradeshows and continues to find value in bringing together like-minded professionals and friendly competitors pitching their products, and selling their services. The most striking takeaway from the IRE this year was that professional education and new product launches took center stage. As one of many exhibiting/sponsoring companies that promoted education and announced new products, it was evident that the roofing industry continues to support these endeavors. With so much activity on the tradeshow floor and the energy that consumes Music City, it was easy to miss some of these excellent promotions. This post is part one of two, and will summarize of some of my favorite sessions from CCM's Training & Education Center on the show floor. Worker Training Programs and NRCA ProCertification™ As the roofing industry faces compelling workforce challenges, it is more important than ever to offer exceptional training and a career path for field workers. Guest speakers from NRCA presented this session that focused on their training and certification programs, and provided guidance on how to attract and retain workers while maximizing productivity—and the bottom line. Increasing Rooftop Productivity With a shortage in qualified labor for the roofing industry, increasing productivity is now more important than ever. During this session sponsored by Versico, guests learned to save on labor and increase rooftop productivity by taking advantage of Versico’s deep lineup of labor-saving product options. Proper Design & Detailing of a Metal Roof Although not a single-ply presentation, this session -co-sponored by Sherwin-Williams and CCM’s Drexel Metals -was worth checking out if you wanted to Make More with Metal. During this session, important factors such as wind speed and other environmental elements, positive and negative loading, roof slope, and roof height were all discussed. All of these elements require special consideration when planning a metal roof system. Single-Ply Roofing Adhesives - Seasonal Options There is a wide variety of adhesive options in the market today: water-based, solvent-based, two-component, and pressurized adhesives; to list a few. The proper adhesive option is sometimes a difficult question to answer, especially when weather conditions become a factor. During this session, best practices were evaluated to promote optimal performance. How to Save Material Costs and Labor by Using EPS in a Single-Ply System CCM’s Insulfoam brand sponsored this session, which discussed how to achieve required R-values with fewer insulation layers and less time overall on the roof. Attendees learned how to get the highest R-value per dollar with hybrid EPS and Polyiso insulation systems in a single-ply system to save time and money. Liquid Applied Roofing: Sustaining Roof Assets CCM’s Carlisle Roof Foam and Coatings sponsored this presentation that covered tools and systematic approaches for evaluating existing roof systems, understanding application constraints, and keys to successful liquid-applied restoration systems. Stay tuned for part two in a couple weeks.     Jason Mortelliti     CCM Marketing Communications Manager     Integrated Marketing Communications     jason.mortelliti@carlisleccm.com

It's All in the Preparation with LIQUISEAL Liquid Flashing

Liquid flashing can solve a lot of problems on the roof; from irregularly-shaped and hard to flash penetrations; to creating tie-ins without impeding the flow of water. However, it can also be difficult to apply and use if not done correctly. By following these simple tips and guidelines, your experience working with LIQUISEAL® Liquid Flashing should go smoothly: LIQUISEAL Liquid Flashing is incredibly durable, but it won’t adhere properly if the surface isn’t prepared. Always use the tables on LF-A, B, & C to determine what preparation is needed for a given substrate. Here are some examples for common surfaces: Metal: Grind clean to expose bare steel or aluminum and create a rough surface before priming. Don’t use a wire brush. Then apply LIQUISEAL Liquid Flashing Metal Primer and allow the primer to cure (this may take several hours). EPDM: Scuff the membrane using 60 grit sandpaper and clean with Weathered Membrane Cleaner. After this is done, apply LIQUISEAL Liquid Flashing Metal Primer and allow the primer to cure (this may take several hours). TPO: Clean TPO with Weathered Membrane Cleaner (do not scuff with sand paper the way you would other membranes) and apply Versico’s TPO Primer. Allow the primer to flash off. PVC & KEE: Scuff the membrane using 60 grit sandpaper and clean with PVC cleaner. No primer is needed prior to application on PVC or KEE membranes. Always pre-cut and dry-fit your reinforcing fleece before mixing the resin. LIQUISEAL Liquid Flashing Resin has a "pot-life" of about 20-30 minutes once mixed, so prioritizing time is key. By taking the time to watch this flashing video or this tie-in video, review the installation instructions on the Versico website, and reviewing details before using LIQUISEAL Liquid Flashing, you will improve your experience with liquid flashing. A little bit of time spent reviewing these can save you a considerable amount of time on the roof, and prevent the potential waste of product.

Keep Your Membrane Splices On Par With Industry Standards

One of the biggest challenges in the application of single-ply roofing systems is ensuring that all seams, curbs, and miscellaneous items are flashed-in per industry standards. Installing a water-tight single-ply roofing system is necessary to ensure a successful, long-lasting, and effective roofing experience. Seams are a fundamental part of the system,and their central purpose is to tie-in one sheet of membrane to another. The proper mating of both sheets at this connection point not only creates one uniform system,but also serves as the first line of defense to moisture infiltration. Many warranty claims can be credited to this aspect of a single-ply system and is a very common reason for roof failure. VersiGard® Pre-Cleaned Non-Reinforced EPDM roofing membrane makes installing seams easier and ensures seam integrity in the long term –resulting in less call-backs,and a better relationship between the contractor and customer. Here are a few benefits to installing seams on VersiGard Pre-Cleaned Non-Reinforced EPDM membranes: The membrane is pre-cleaned to remove mica dust, therefore eliminating the need to clean the seam areas with Weathered Membrane Cleaner prior to the application of primer. Pre-cleaned EPDM allows primer to be applied with a roller. Versico’s Quick-Applied Tape is available on all VersiGard Pre-Cleaned Non-Reinforced EPDM membranes up to 10-feet wide,which greatly reduces the seam completion time. The above steps will save on labor in the field, create less jobsite waste,and result in a quality-controlled installation. Please reach out to your local Versico Representative for more information about our VersiGard Pre-Cleaned Non-Reinforced EPDM products.

Safety First In All Kinds of Weather

Roofs may need to be functional in all weather; but when installing or inspecting a roof in cold weather, extra care must be taken. Versico has put together a list of cold weather installation and safety tips to make sure you put down the best roof possible, while staying safe! Safety Tips Dress properly for the weather conditions  Be aware of skylight and hatch openings that may be covered by snow. Check the roof plans for the locations of any penetrations.  Be aware of your position on the roof with respect to perimeters and other roof levels.  Check for icy surfaces that may be hidden by snow, and check for iced rungs on ladders.  In colder weather, white membranes reflect heat and can promote slippery conditions due to ice build-up that may not be visible.  Installation Tips VersiGard EPDM - Use non-folded sheets for cold weather installation. EPDM flashing products may require additional warming from a heat gun in cold weather.  VersiWeld TPO & VersiFlex PVC - TPO and PVC membranes and walkway rolls must be allowed to relax after they are unrolled and before installation. Also, welding techniques must be adjusted for cold weather application.  Low-VOC Bonding Adhesives and Primers - Store these products between 60°F - 80°F, and if outside temperatures are going to be less than 40°F, a heated enclosure or hot box is recommended for jobsite storage. TPO and EPDM membranes should be relaxed for 30 minutes or more before applying adhesives in cold weather.  CAV-GRIP 3V - This adhesive can be applied in temperatures of 25°F or above, but the cylinder must be kept above 60°F for the product to spray properly.  Flexible DASH - Store this product between 60°F - 80°F and return to 70°F before use. Flexible DASH can be applied in temperatures of 25°F or above, but if temperatures are below 60°F, hot boxes or heated blankets are recommended.  If you have any other questions regarding cold weather installation tips, please refer to this Installation Advisory or reference the Technical Data Bulletin of the Versico products you are using.
