New High-Density Polyiso Cover Board Offers Grade 1 Compressive Strength

Johns Manville (JM) introduces its ProtectoR HD High Density Polyiso Cover Board. According to the manufacturer, it provides excellent protection and can save time and expense for contractors. With a closed cell polyiso foam core and inorganic coated glass facers, this high-density cover board has a Grade 1 compressive strength and an R-value of 2.5. The product offers excellent resistance to moisture, hail, wind uplift and puncture, plus its light weight makes it easy to handle.

According to the company, the product has the lowest fastening rates in the market for a HD polyiso cover board — up to 50 percent fewer fasteners are needed to achieve FM I-90. As an example, it takes only eight fasteners per 4-foot-by- 8-foot board with adhered reinforced membrane (TPO, PVC, EPDM-R, mod bit) applications over a minimum 22 gauge steel or structural concrete deck to achieve FM 1-90 performance. 

“ProtectoR HD is an important addition to our polyiso cover board offering,” noted Tesha Kroll, Director of Product Management, Roofing Systems at JM. “It expands our line with a half-inch, high-density product and gives us the most comprehensive offering in the industry.”

White Mod-Bit Cap Sheets Offer Superior Granule Embedment

Polyglass U.S.A. Inc. announces important new updates to Polyfresko, a highly-reflective, white modified bitumen membrane cap sheet used as the final layer in a multi-ply roof system or as a flashing membrane. 

According to the manufacturer, independent laboratory testing confirms Polyfresko’s superior granule embedment and documents its aged reflectivity performance. Granule embedment was tested using ASTM D4977 Standard Test Method for Granule Adhesion to Mineral Surfaced Roofing by abrasion. The recently completed three-year aged reflectivity testing was conducted in three different climate zones, and demonstrated that Polyfresko maintains reflectivity performance over time. The product was deemed suitable for most Cool Roof specifications due to Polyfresko’s initial and aged reflectivity and emissivity performance. The laboratory testing results enabled Polyfresko to gain Energy Star Certification.

Polyfresko is manufactured with proprietary CURE Technology, a thin film technology infused with ceramic microspheres, ultraviolet (UV) stabilizers, and proprietary resins. This increases weatherability and decreases maintenance costs by “locking-in” the granules, so the high-performing Polyfresko membrane maintains reflectivity performance over time, decreases UV degradation, and increases abrasion and impact resistance. 

In addition, all Polyfresko products are now manufactured with FASTLap technology, a patented granule-free end lap that helps make the membrane watertight and increases speed of installation. Polyfresko is available in Polyglass’s APP (Atactic Polypropylene) and SBS (Styrene-Butadiene-Styrene) formulations and is adhered to the roof deck or other approved substrates by torching or self-adhered application.

“Granule loss is one of the challenges with modified bitumen membranes, and our new granule adhesion testing results show that Polyfresko is a premium solution, firmly positioned as a top performing product,” says Polyglass CEO Natalino Zanchetta. “The granule adhesion results achieved with our CURE Technology, together with our new three-year weathering milestone, demonstrate our leadership with asphaltic membrane cap sheet performance.”

Pre-Cut Fleece Saves Time Flashing Pipe Penetrations, Corners

Soprema Inc. releases a new time-saving product option for roofing and waterproofing contractors: ALSAN RS Pre-Cut Fleece. ALSAN RS Fleece — a proprietary nonwoven polyester reinforcement used in ALSAN RS PMMA applied waterproofing membrane applications — was previously only available to roofing contractors in a roll format. Now, ALSAN RS Fleece can also be purchased inpre-cut detail kits intended for use with large and small pipe penetrations and inside and outside corner installations. 

With ALSAN RS Pre-Cut Fleece, contractors can now expedite project timelines by no longer spending valuable time cutting fleece during installation. They can also reduce waste associated with unusable fleece scraps, while reducing the opportunity for cutting-related errors. 

When used with ALSAN RS flashing products, ALSAN RS Pre-Cut Fleece provides a cost-effective and easy-to-apply means of addressing difficult detailing and irregular shapes encountered when waterproofing a roof. The result is a seamless, watertight, puncture-resistant, fully reinforced flashing system over SBS-modified bitumen or SENTINEL PVC membranes.

“We are continuously looking for ways to help contractors do more in less time with less waste, especially in the face of an industry labor shortage,” said Tom Stuewe, product manager from Soprema. “ALSAN RS Pre-Cut Fleece is our latest release consistent with this goal, and we anticipate roofing system installers will find it to be an even more convenient version of a product they already trust.”

Yellow Walkway Coating System Protects Roof From Foot Traffic

Metacrylics introduces a new yellow coating system that allows installers to create distinct, walkable paths to roof areas and access points that require routine maintenance. WalkwayYellow provides a textured surface, protecting the roof from damage caused by repeated foot traffic. 

WalkwayYellow can be installed on coated and non-coated roofs as an alternative to solid walkway products. Because it is liquid applied, WalkwayYellow allows for custom walkway paths to better accommodate the roof layout. The product can also be used to clearly identify roof edges, equipment, and other areas to avoid. 

Gary Rosenfield, vice president and general manager of Metacrylics, said, “We are excited to offer this additional product to our coatings line. We believe it adds significant value, and saves the cost of walkway pads required on many commercial roofs.”

According to the manufacturer, WalkwayYellow meets the ANSI A137.1 dynamic coefficient of friction requirements in the international building code.

Capped Skylight Conversion Kit

Skyco Skylights offers the Capped Conversion Kit, which converts old capless skylights to a more trusted capped system. With the kit, commercial roofers receive a universal fitting Polycarbonate dome, a custom-sized aluminum cap, and Tek Screw with EPDM gaskets.

According to the company, using a cap around the perimeter of the polycarbonate dome creates a leak-free seal and eliminates cracking. The custom-fitted aluminum cap is fastened to the skylight frame with Tek-Screws instead of drilling through the plastic dome. Penetrating the dome with screws is a major cause for cracking. Many times, installers will over-torque the screw, immediately cause the dome to crack. Drilling through the Conversion Kit’s aluminum cap into a steal frames makes it easy to drill without cracking. 

Accroding to the manufacturer, the average install time for two installers is 1-2 minutes per kit. Watch the install video here.

Primer for Silicone Roof Coating System Offers Improved Adhesion, Blocks Asphalt Bleed-Through

Mule-Hide Products Co. Multibase SBMule-Hide Products Co. has expanded its Silicone Roof Coating System with Multibase SB, a new primer that delivers stronger adhesion and prevents asphalt bleed-through in non-ponding water conditions. Multibase SB is a one-part, 100 percent acrylic-based resin intended for use as a primer prior to the application of Mule-Hide 100% Silicone Roof Coating. It can be used on modified bitumen, asphaltic built-up roofing (BUR) and PVC roof surfaces.

According to the manufacturer, the primer contains minimal pigment and no mineral fillers, enhancing its adhesion to the roof surface. In addition, its relatively thin viscosity and low surface tension allows the primer to completely saturate the roof surface, further helping form a strong bond.

Multibase SB blocks asphalt bleed-through, helping ensure that white finish coats are clean and bright and deliver optimal reflectivity. The primer can be applied using airless spray equipment, a roller or a brush. Its light yellow color cures to a darker amber hue as the coating dries, providing visual confirmation that the coating has cured and the finish coating can be applied.

It is not intended for use on coal-tar-pitch roofs, on TPO membranes or in areas that experience ponding water. Multibase SB is available in 5-gallon pails and 55-gallon drums.
