“We see a new era of opportunity to provide greater value to our customers by expanding our cornerstone products: Aptra UV8 film and RoofTopGuard II underlayment. Aptra Elements and RoofTopGuard Craftsman will better address the need for energy savings and installation speed in the new world of construction. Only RKW has the intellectual property, global relationships and might to launch these products.”
Aptra Elements is a metallic, highly reflective roof underlayment that reduces home and building energy costs. The second product, RoofTopGuard Craftsman roof underlayment, is based on RKW’s premier RoofTopGuard II technology but weighs 40 percent less, and installs faster and easier than #30 lb. felt paper.
Aptra Elements keeps the house warmer in the winter and cooler in the summer. The advanced material maintains strength and flexibility without the metal surface rub-off or oxidation. Breathable, waterproof and durable, the engineering breakthrough is available in various weights for wall and other roofing components.
Aptra Elements uses technology based on Aptra UV8 microporous film and science from confidential European and US partners. Product characteristics include a surface reflectivity of 0.97% and emissivity of 0.03% bonded with light-weight, UV-stabilized, non-abrasive, water-resistance and mold-barrier properties of Aptra UV8 film.
RKW’s new RoofTopGuard Craftsman underlayment offers waterproof secure protection and durable strength with economical pricing for temperate climates where premium high-wind protection is not required. RoofTopGuard Craftsman is made of reflective grey, nonwoven-coated spunbond polypropylene and applies 30% faster compared to traditional asphalt felt.
RoofTopGuard Craftsman covers a 1,200-square-foot house in one or two light-weight rolls compared to 30-pound felt paper that could require five or more rolls to cover the same house. Each roll of RoofTopGuard Craftsman covers 1,000 square feet or nominal 10 squares per roll; compared to 30 pound felt paper that covers 200 square feet or two squares per roll.
Economical pricing, fewer and lighter weight rolls mean value, less waste and faster installation for the roofer with quality performance for the home owner. RoofTopGuard Craftsman provides excellent slip resistance, is not affected by humidity or rot and lays flat without wrinkling or buckling when mechanically fastened to the roof deck.
