Channel Venting Base

Aid in Venting Latent Moisture

Elevate 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 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 Elevate modified bitumen or built-up roofing systems. The sanded top surface is suitable for installation of the roofing system using a self-adhered base sheet, hot asphalt, Elevate MB Cold Adhesive, or a roofing torch.
