Firestone Channel Venting Base is an oxidized asphalt-coated fiberglass base sheet with granules on the underside of the membrane. There is a slight grid pattern embossed into the granules to further aid in venting of latent moisture in the existing roof system or deck. It is designed to be mechanically fastened over lightweight concrete roof decks or other surfaces as a base for Firestone modified bitumen or built-up asphalt roofing systems. The top sanded surface is suitable for installation of the roofing system using hot asphalt, Firestone MB Cold Adhesive or a roofing torch.
