Vapor Diffusion Ports Explained...

In this video we break down vapor diffusion ports, a strategy for managing moisture in unvented roof assemblies in warm climates (IECC zones 1-3) using a highly vapor permeable membrane at the roof ridge. Unlike traditional ridge vents, diffusion ports are airtight and watertight, while allowing vapor to escape without air infiltration. This method enables the use of fibrous insulation without exterior insulation or spray foam, reducing cost and complexity.
