SlopeShield Plus SA® Self-Adhered Roofing Underlayment Introduced By VaproShield
Gig
Harbor, WA - VaproShield, supplier of breathable membrane systems for roofs and walls, announces the new product 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. The 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,” noted 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.
“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.
The construction technology of SlopeShield Plus Self-Adhered is a composite of polymers and polyester in a sheet good that allows vapor diffusion. 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" and 19 2/3”. SlopeFlashing
is used to flash eaves, hips, ridges and valleys.
Complete Roof And Wall Water Resistant, Vapor Permeable Air Barrier System
It was noted that 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 NIST (National Institute of Standards and Technology, NISTIR 7238) study showed that an effective air barrier can reduce a building’s energy costs by as much as 40%
and electrical costs by more than 25%.
