New Bath and Dryer Vent Designed for Shingle Roofs

Lifetime Tool introduces the Lifetime Bath-Dryer Vent for shingle roofs. The proprietary design enables the housing structure to mount to the plate without rivets, fasteners and sealants — common leak points in existing vents. The vent assembly is crimped into the seamless deep-drawn plate with an EPDM gasket which guarantees a forever water-tight seal, according to the company. The shingle vent plate is 24-gauge galvanized Kynar with 4 inches of flashing on the sides, 6 inches at the top and 3.5 inches at the bottom. Most existing vents have less than half of these needed requirements, which exponentially increases the likelihood of edge leaking. According to the manufacturer, in independent laboratory testing the Lifetime Bath-Dryer Vent exceeded 90 mph in the ASTM T166-18 – Wind Driven Rain Test, easily surpassing all of the competition. 

The product features a 24-gauge galvanized Kynar cap that is clad onto a high-temperature polymer with a heat deflection above that of boiling water. According to the company, this carefully researched and tested premium polymer was chosen for its extreme performance and its ability to retain its mechanical properties for decades of use. 

Additionally, the cap assembly is attached with two black oxide stainless fasteners and 316L stainless clips for easy removal for periodic maintenance. A gold anodized aluminum damper, preventing white corrosion, and its passivated stainless steel axle are mounted on the angled structure to ensure condensation drainage and provide protection from wind and rain penetration. Its built-in weep holes, wind walls and recessed EPDM noise bumpers help eliminate clatter. The EPDM bumpers also permit a small amount of warm air to pass between the structure and damper to reduce the chance of condensate freezing. A snap-in high-quality polymer frame has a stainless steel screen included for use in bath venting only.

Finishing the assembly is a proprietary 6-inch-high, 4-inch round 26-gauge G90 galvanized drop with a unique button punch/window snap connection assembly. A 4-inch/3-inch reducer is also included.

New Low-Rise Adhesive Offers Greater Elongation and Tensile Strength

Mule-Hide Products Co. introduces Helix Max Low-Rise Adhesive, a two-component, construction-grade polyurethane foam adhesive designed to bond approved roof insulations, thermal barriers, cover boards and fleece-back single-ply membranes (TPO, PVC and PVC KEE) to a wide variety of roofing substrates. It replaces Mule-Hide Helix Low-Rise Adhesive.

According to the manufacturer, Helix Max Low-Rise Adhesive delivers the quick, low-odor application and strong adhesion that have made Helix Low-Rise Adhesive a go-to choice for roofing contractors, while also offering greater elongation and tensile strength, the ability to be applied in colder temperatures, and the additional packaging option of convenient 5-gallon jug sets.

Like the original Helix, Helix Max is applied in a single step, saving crews time and hassle. Both parts of the adhesive are ready to use from the container and are applied simultaneously in a 1:1 ratio through a static mix tip. It eliminates the need for mechanical fasteners, maintaining a continuous vapor retarder, preventing thermal bridging and protecting the structural integrity of the roof deck.

Helix Max can be applied in colder temperatures, helping prevent weather-related delays. The substrate and ambient temperature must be above 25 degrees Fahrenheit when applying Helix Max, compared to 32 degrees with the original Helix.

According to the company, elongation of up to 150 percent and increased tensile strength ensure an exceptionally strong bond. Superior wind uplift resistance enables Helix Max to be used on taller buildings and in higher wind zones. The adhesive also is better able to withstand extreme temperatures.

Full-spray splatter application when installing fleece-back membranes provides superior hail resistance and improved energy efficiency. Puncture resistance is increased by 33 percent to 50 percent when full-spray splatter application is used. A continuous layer of Helix Max increases a roofing system’s R-value by 0.20 to 0.50 per layer.

The addition of 5-gallon jug sets provides a convenient packaging option for use with low-pressure spray equipment. Made of plastic, the jugs are easily moved around the jobsite and will not dent during transportation or if dropped. Handles on the jugs’ tops and sides make them easy to load onto dispensing equipment. The containers resist moisture, preventing contamination of the adhesive. 

Helix Max is low-odor and solvent-free and contains no volatile organic compounds (VOCs), chlorofluorocarbons (CFCs) or hydro chlorofluorocarbons (HCFCs), making it crew-, building occupant- and environment-friendly.

In addition to the new 5-gallon jug sets, Helix Max is available in twin-pack cartridges, tanks, and 15- and 50-gallon drums.

Lead-Free Roof Flashing Formally Approved by IAPMO UES

Boral Roofing LLC announces that Wakaflex, the company’s versatile flashing solution, is now listed through IAPMO UES as a permanent flashing (ER-579). The product earned the distinction by undergoing and passing an extremely rigorous 2,000-hour UV exposure test. 

During testing, the product maintained its original performance properties, which include the adhesion of the butyl strips to various materials including concrete, clay, stone coated steel, polymer roofing, aluminum, galvanized steel, vinyl and wood structured panels. The approval also includes the use of Wakaflex as a permanent flashing for solar applications in California.

“Wakaflex is tough and durable, and its numerous applications and performance abilities make it ideally suited for use with virtually all roofing materials,” said Brian Sweet, components product manager with Boral Roofing. “This IAPMO UES listing is important as it clearly demonstrates the performance capabilities of the product to building officials and homeowners.”

Ideal for difficult and complex details, Wakaflex contains an internal aluminum mesh, making it extremely flexible and easy to shape and form to virtually any surface. Wakaflex chemically seals to itself and its Polyisobutylene material composition makes the flashing extremely resistant to all weather conditions.

The flashing may be used for step flashings, headwalls, pipe penetrations, pitch transitions, valley junctures, valley soakers, chimneys and skylights. It may also be used as a solution for solar panels, hip and ridge junctures, sidewalls, splayed gables, and various repair applications as well as for tricky details that require weather protection.

One highly notable product attribute is its lead-free composition. OSHA has declared that “lead adversely affects numerous body systems and causes forms of health impairment and disease which arise after periods of exposure as short as days or as long as several years.”  

“Lead is still the most commonly used flashing material, and with so many ongoing safety concerns surrounding exposure to it, there is a legitimate need for alternative options,” added Sweet. “Any place that lead is used on a tile roof, Wakaflex works better and more safely.” 

 Wakaflex is offered in 22-pound 11” x 33” and 27-pound 22” x 16.5” rolls. The product is also certified by Miami Dade NOA 08-1106.03 for use in hurricane-prone regions of Florida, Hawaii and coastal Texas.

Dual-Class Self-Retracting Devices Meet Both Class A and Class B Guidelines

Malta Dynamics introduces the Hybrid Hog, the new Dual Class Self-Retracting Lifeline that gives you the advantages of both Class A and Class B retractables, all in one. The Hybrid Hog comes in both a 20′ Dual Class SRL and a 30′ Dual Class SRL.

Self-retracting lifelines (SRLs) are a staple piece of personal fall protection equipment used to keep workers safe when working at heights. SRLs generally come in two versions—Class A and Class B—established by ANSI standard Z359.14-2012. Both types of SRLs limit the maximum peak arresting force to 1,800 pounds as required by OSHA (OSHA 1926.500 subpart M) when worn with a body harness, but the two classes differ on two key dimensions: maximum arrest distanceand average arresting force.

Class A SRLs are defined as devices that provide a maximum arrest distance of 24 inches (610 mm) and an average arresting force not exceeding 1350 pounds (6kN). This class of SRLs is designed to arrest a falling worker very quickly, and is typically used in areas where fall clearance is limited. Think of it like slamming on the brakes in your car when you need to stop immediately—it may be a little jarring, but what matters is stopping before you hit anything.

Class B SRLs are devices that provide a maximum arrest distance of 54 inches (1372 mm) and an average arresting force not exceeding 900 pounds (4kN). This type of SRL also stops a falling worker safely but arrests the fall a bit more gently. Slowing to a stop over a longer distance makes the stop less jarring. This is why you gradually slow to a stop when you’re driving up to an intersection instead of slamming on the brakes—it’s a lot more comfortable if you can afford to slow down gradually.

The new Hybrid Hog from Malta Dynamics combines the advantages of each class into a single device that meets the standards for both classes. The Hybrid Hog offers a maximum arrest distance of just 24 inches to qualify as Class A while alsolimiting the average arresting force to 900 pounds to qualify as Class B.

Advanced Polymers for the Manufacturing of TPO Membranes

Dow’s portfolio of materials for roofing membranes features advanced polymers for thermoplastic polyolefin (TPO) systems. These proven, highly respected solutions can help manufacturers develop custom-tailored formulations that fit specific designs, production processes, and end-use requirements. With several advantages over incumbent materials, ENGAGE TR Polyolefin Elastomers (POEs) represent the company’s current state-of-the-art for TPO-based membrane formulations. According to the manufacturer, ENGAGE TR POEs offer an ethylene-based solution that has inherently better longevity, and can be formulated to produce membranes with significantly improved flexibility and broad welding window. The unique design of ENGAGE TR also allows increased filler loading, which can, in turn, be used to improve fire performance.

According to the manufacturer, in a comparison of formulations based on a typical polypropylene (PP) TPO and ENGAGE TR, the Dow material offers:

  • 40 percent lower modulus for increased flexibility and ease of installation
  • Reduced glass transition temperature (Tg) for better low temperature toughness
  • Excellent thermal stability which can help deliver better property retention over time

Membranes formulated with ENGAGE TR POE offer increased weatherability/UV resistance, according to the company. Scanning electron microscope (SEM) photography taken after 10,000 hours of accelerated weathering reveals surface cracking in the PP TPO-based membrane. In sharp contrast, the ENGAGE TR POE-based membrane remains crack free at the same stabilizer package. This indicates higher levels of UV and weather resistance, which correlate to longer service life. Better UV resistance is expected for a polyethylene based chemistry thanks to the lack of tertiary carbon which is intrinsic to PP and prone to chain scission.

According to the company, whether you’re working with TPO-, PVC- or EPDM-based systems, Dow’s roofing membrane science can offer:

  • Flexibility that lasts, even in thicker sheet installations
  • Long-term durability
  • Weatherability/UV resistance that meets or exceeds appropriate industrial standards
  • Fire performance with halogen-free, low-smoke, low-ignitability, and low-fuel load options
  • Light color/cool roof formulations to reduce heat absorption
  • Multiple attachment options, including fully adhered, heat welded, mechanical, and/or ballasted systems
