CedAir-Mat® is a roof ventilation mat designed to create an airspace / cavity to promote air flow in all directions between the roofing material and the sheathing below. Using a thin nylon matrix profile, CedAir-Mat® prolongs the life of the roof structure and membrane by reducing the adverse effects associated with moisture / water damage including mold, mildew, corrosion and deterioration of the roofing material itself. CedAir-Mat® is extremely flexible and conforms to any contoured surface or roofing material and is perfect for residential and commercial roof applications.
