Vapor Permeable Underlayment Designed for Use on Steep-Slope Roofs

VaproShield announces the release of SlopeShield Plus Self-Adhered, a highly vapor-permeable roofing underlayment Air Barrier (AB) material. SlopeShield Plus Self-Adhered (SA), a vapor permeable roofing underlayment, is designed for use on steep slope roofs of 2:12 or greater pitch. According to the manufacturer, the roofing underlayment features the patent-pending Vapor Permeable Polymer Composite Technology (VPPCT) developed by VaproShield.

“VPPCT combines advanced polymer coatings and our proprietary adhesive to create a primerless, highly-permeable, and fully-adhered [roofing] underlayment that is revolutionary to the industry. The black color also absorbs heat from the sun (while exposed), which increases the drying process of wet sheathing and insulation,” said Kevin Nolan, Technical Director of North America. “Every part of SlopeShield Plus, including the color, was intentional.” 

The development of SlopeShield Plus Self-Adhered came from an existing market demand for a high-performance and permeable roofing underlayment. Traditional asphaltic and butyl-based peel-and-stick roofing underlayments offer liquid-water holdout but lack drying capacity due to their non-permeable nature. These underlayments inherently trap moisture, reducing insulation performance and accelerating sheathing decay-potentially causing premature roof assembly failure.

“The industry has had traditional [asphaltic and butyl-based] underlayments for years. We are always working to push the industry forward,” noted Lee Snyder, Managing Partner of VaproShield.

SlopeShield Plus Self-Adhered offers superior performance to the polypropylene tri-laminate micro-porous permeable existing roof underlayments. The superior construction technology of SlopeShield Plus Self-Adhered is a composite of polymers and polyester in a sheet good that allows vapor diffusion. According to the company, the design of SlopeShield Plus Self-Adhered eliminates the water leakage created by the concussion effect (caused by heavy rain and foot traffic) while allowing for 6-month UV and climate exposure prior to roof system installation.

SlopeShield Plus Self-Adhered is compatible with metal roofing, slate/clay tile with batten/counter-batten substructures, and cedar shingles/shakes with VaproMat. VaproShield offers SlopeFlashing in two sizes: 29.5 inches and 19 2/3 inches. SlopeFlashing is used to flash eaves, hips, ridges and valleys.

Combining SlopeShield Plus SA and VaproShield’s vapor permeable WRB/Air Barrier wall membranes will create an airtight and watertight building enclosure that offers high drying capacity for the building envelope and roofing assembly-mitigating moisture damage and saving energy for the life of the building. A National Institute of Standards and Technology (NIST) study (NISTIR 7238) showed that an effective air barrier can reduce a building’s energy costs by as much as 40 percent and electrical costs by more than 25 percent.

New Membrane Delivers UL Class A Fire Rating

Designed for attachment directly to plywood and oriented strand board (OSB) roof decks, new TPO Fleece Back FR membranes from Mule-Hide Products Co. deliver a UL Class A fire rating without the need for a fire-retardant barrier board or slip sheet.

“TPO Fleece Back FR is ideally suited for use in the West, where fire is a significant concern and building codes require many buildings to have Class A fire-rated roofing systems,” said Ken Schultz, West regional director for Mule-Hide Products. “Building owners get the necessary Class A fire rating. Contractors get a faster, easier installation by eliminating the need to add a fire-retardant barrier.”

Fleece reinforcement gives the membrane an added layer of protection against punctures. Splinters from OSB and plywood roof decks will not create holes in the membrane – a common issue when standard membranes are attached directly to these materials. More puncture-resistant than modified bitumen membranes, it stands up to hail and damaging debris exceptionally well.

Large sheet sizes and a wide window of weldability make installation quick and easy. TPO Fleece Back FR is available in 10-by-50-foot and 10-by-100-foot sizes; this is significantly larger than typical modified bitumen sheets, reducing the number of seams to weld by 67 percent. The ability to weld at wide ranges of temperature and humidity also means fewer stops to adjust the settings on the automatic welder and perform a test weld.

TPO Fleece Back FR membranes remain flexible in low temperatures and offer excellent resistance to impacts. They also stand up to acids, bases and restaurant exhaust emissions without degradation.

Like all Mule-Hide Products TPO membranes, TPO Fleece Back FR membranes include the Mule-Hide Products Weathering Package, ensuring that the membrane will withstand exposure to severe climate conditions. The weathering package is comprised of three heat-stabilizing antioxidants, three ultraviolet (UV) light stabilizers and two UV light absorbers, making the membrane highly resistant to heat, sun, ozone and oxidation.

TPO Fleece Back FR membranes contain no chlorine, plasticizers or volatile organic compounds (VOCs) and are odor-free, making them an environment-, crew- and building occupant-friendly choice.

Insulation Adhesive Canisters Enhance Rooftop Productivity

Each OlyBond500 canister set is self-contained, and comes with a 25-foot application hose, gun assembly, six mix tips, three extension tubes as well as a disposable wrench for securing the hoses to the canisters. The unique applicator “gun” includes a locking trigger designed to prevent accidental adhesive discharges on the roof. The 17-inch long extension tubes enable contractors to stand upright during application for better ergonomics and less fatigue.

“On almost a daily basis we’re hearing from contractors from across the country that OlyBond500 Canisters provide a highly labor efficient method of installing insulation adhesives,” said Adam Cincotta, adhesives business unit leader for OMG Roofing Products. “They love the fact that these systems do not require any extra or specialized equipment, rooftop power or highly skilled labor. Just connect the hoses and go!”

When compared to other canister based low-rise foaming adhesives, OlyBond500 Canisters can provide up to 20 percent more coverage and up to 35 squares per set, depending on the conditions and insulation used, according to the manufacturer. In addition, OlyBond500 Canisters enable users to spatter the adhesive for use with fleece backed membranes.

“In addition to productivity gains, canisters do not require highly skilled applicators, so contractors can assign skilled labors to work on other things rather than applying adhesive,” said Cincotta. “I expect to see more contractors adopt this strategy as the labor shortage continues.”

High Wind-Resistant Roofing System

Polyglass announces the new Velociflex high wind-resistant roof assembly system. Independently tested, the Velociflex system provides for high-speed wind protection up to 270 psf (pounds/square foot).

The core of Velociflex is two or three plies of reinforced modified bitumen membranes. Suitable for new or re-roofing projects, this multi-ply system comprises of a mechanically fastened base sheet, optional interply, and a heat-welded or cold-applied cap sheet. According to the manufacturer, Velociflex is ideal for both steel and concrete decks.

The self-venting Velociflex system’s “loose-laid,” mechanically attached base sheet reduces the likelihood of blistering from substrate to membrane. Attached at the seams only, it also limits material and labor costs. Plus, the watertight system acts as a temporary roof once base sheet seams are heat-welded. Fast and efficient to install, the Velociflex system dries in fast, so projects can proceed with phased construction before cap sheet installation. 

Installed with a Polyfresko G cap sheet with initial Solar Reflective Index 96, the Velociflex system complies with 2016 Title 24 Part 6 Cool Roof Requirements and is ENERGY STAR Certified. The Velociflex system is also compatible with a variety of SBS and APP cap sheets from Polyglass, including Elastoflex, Polyflex, and Elastoshield membranes.

New PVC Trimboard Accessories Added to Product Lineup

Palram Americas has launched a new family of PVC trimboard accessory products for its Color2Core (C2C) product lineup. The C2C line (home to a full offering of matching dimensional foam PVC trimboard) now includes PostWrap Column Wraps and Corners, plus two extruded decorative mouldings – Bead Board with Nail Flange and Brick Mould. The new accessories are available in three C2C colors – White, Sand and Clay – in multiple widths and lengths.

The new PostWrap Column Wraps use the patented Wrap-n-Snap design for quick installation by just one person. The flat-pack design makes it easy for both dealers and contractors to handle the material. There’s no waste by storing and moving “air” as with box-style column wrap designs. Palight PostWraps are available for 4, 6 and 8-inch posts in 8’6-inch and 10-foot lengths, and either smooth or woodgrain finish.

Palight Trimboard Corners are milled and glued from a single Palight Trimboard. The fabrication process leaves a thin “skin” of surface material in the center, so there is no visible joint or seam to finish during installation. Palight Corners come with EverClean Protective Film. Corners are available in 4, 6 and 8-inch widths and 20-foot lengths, with either a square or a rabbeted edge, and a smooth or woodgrain finish.

Palram is also adding two C2C decorative mouldings to its moulding lineup. The new 6-inch Bead Board with Nail Flange gives contractors new options for no-paint solutions for porch ceilings and wainscoting. And the Brick Mould provides the finish touch of color for many window and door surround designs.

Stone Wool Insulation Board Is Thermally Efficient, Non-Combustible

HARDROCK (DD) TRB (Thermal Roof Board) is a rigid, dual-density stone wool insulation which is purpose-designed to give an enhanced thermal performance across roofs that are subject to maintenance-only foot traffic. Manufactured using Rockwool’s patented dual-density technology, this A1 non-combustible thermal roof insulation board is ideal for large flat roof areas typically found on storage, logistics and distribution centers, as well as for education, healthcare and residential roofing applications.

“The roof is often overlooked in terms of fire safety, particularly from a regulatory standpoint, which can result in specifiers inadvertently yet routinely introducing a weak link into the building envelope via the unconsidered ‘fifth façade,’” said Will Wigfield, Product Manager at Rockwool. “However, there now exists a non-combustible flat roof insulation capable of meeting stringent thermal requirements in just one layer – offering contractors a quick and easy install without compromising fire safety. HARDROCK (DD) TRB achieves the highest-attainable Euroclass A1 rating under EN 13501-1, meaning that it simply will not burn.”” 

According to the manufacturer, HARDROCK (DD) TRB is easy to handle on site, and in the majority of applications can be securely installed within a mechanically-fixed single-ply waterproofing system using just one fixing per board, in contrast to the multiple fixings needed with PIR / PUR foam board installation. (Note: Exceptions may occur that demand multiple fixings, including, for example, the corner regions of flat roof systems, which are subject to increased external suction and internal pressure force, and require more fasteners.) The result is a quick and simple installation, reducing any risks of cold bridging that may otherwise compromise thermal performance. The product is also compatible with all commonly used flat roof membranes, including single-ply and EPDM, bitumen membranes and liquid-applied systems.

Manufactured from basalt rock, which is melted, spun and bound to create stone wool insulation boards, HARDROCK (DD) TRB is dimensionally stable, eliminating the need for any mechanical fasteners to prevent differential thermal expansion and undue stress on the waterproofing membrane. It is also water repellent and completely unaffected by damage caused by the freeze/thaw cycle, according to the manufacturer.

HARDROCK (DD) TRB Thermal Roof Boardis available as a specification-only product, supported by Rockwool’s Technical Solutions team who can provide U-value calculations, BIM modelling, and detailed technical guidance for all projects.
