CedAir-Mat ® is a roof ventilation mat designed to create an airspace to promote multi-directional air flow 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 water damage including mold, mildew, or corrosion and deterioration of the roofing material itself. CedAir-Mat ® is extremely flexible and conforms to any contoured surface or roofing material (cedar and tile) and is perfect for residential and commercial applications.
