GAF Materials Corp. has launched two Master Flow™ roof louvers.
GAF Materials Corp., Wayne, N.J., has launched two Master Flow™ roof louvers with predrilled nail holes and extra-wide flashing area for easy installation. The RT65 is constructed of polypropylene and has a noncorroding screen that deters birds and small animals. It has a full 50 square inches of net-free ventilation area per vent and is scratch-, crush- and dent-resistant. It is available in four colors. SSB960 has a distinctive aluminum slant-back design. It offers 20 percent more ventilation, a full 60 inches of net-free ventilating area per vent. Ultimately this means fewer vents needed for installation, which translates into lower installation costs. The louver has aluminum rust-free construction, offers an embossed finish that hides scratches and resists wrinkles, and comes in six colors.
