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.
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).
