GAF has made available its Cobra IntakePro Rooftop Intake Vent, which promotes energy efficiency and helps guard against roof system rot, ice damming and mildew growth. It can also improve attic ventilation airflow by up to 20 percent when installed with existing soffit/undereave vents in a properly balanced ventilation system (based on GAF ASHRAE airflow testing at 5-mph wind speed). The vent, which rolls out and fastens with included 1 3/4-inch coil nails, is fully tested to withstand wind-driven rain, snow and ice-dam infiltration (under controlled GAF laboratory testing).
Roof specifiers and installers can now achieve project goals in fire resistance and solar reflectance more easily with CertainTeed Presidio Metal Roofing, according to the latest editions of industry performance test standards. Introduced last year, the line of steel roofing products blends the look of classic roofing materials with the exceptional wind/hail resistance and solar reflectance of metal roofing.
New fire rating requirements issued for Class A and B fire ratings by UL 790, the industry standard for fire-resistant roofing, make it easier for building professionals to achieve higher fire ratings with Presidio. Specifiers now can achieve Class A fire rating with Presidio by using a fire resistant rated rolled roofing underlayment as the bottom layer placed over roof sheathing—a structural panel is no longer needed. Further, the metal roofing products now earn a Class B fire rating when paired with any standard CertainTeed roofing underlayment.
In regards to solar reflectance, seven colors from the Presidio roofing product line have recently been approved for compliance with California Cool Roof Rating Council (CRRC) standards: Presidio Tile colors English Toffee, Nutmeg, Speckled Bronze and Terra Cotta, and Presidio Shake colors Ash, Sand Dune and Weathered Wood. Each of these products received a “Best” rating in CRCC’s good-better-best tier system, with solar reflectance ratings ranging from 0.26 to 0.34.
“Sustainability and providing customers with products that help ensure the safety of homeowners have long been top priorities at CertainTeed,” says Dale Walton, residential products manager for CertainTeed Roofing. “And, the recent reports from UL and the CRCC serve as proof of this commitment. With Presidio, specifiers and contractors will have the peace of mind to install the highest quality energy-efficient, fire-and weather-resistant roof, all while more easily meeting project certification goals.”
Each easy to install Presidio panel has overlaps that conceal the joints and create a seamless appearance. Presidio Tile embodies the same Mediterranean magnetism of traditional clay, but weighs hundreds of pounds less, and at a fraction of the cost. Presidio Shake is pre-weathered, aged and distressed to recreate the look of wood. Lastly, Presidio Slate showcases the natural beauty of stone in a lightweight, fully recyclable, energy-efficient material.
