How to install a vapor barrier to control radon and vapor intrusion

Reef Industries offers a complete system of polyethylene vapor retarders, seaming tapes, and pipe boots for total moisture infiltration control. There are several levels of permeance to choose from to meet the specific project demands for roofing, wall and under slab applications.

Reef Industries’ Griffolyn® vapor barriers and vapor retarders can prevent water vapor from causing poor insulation performance, structural damage and other moisture related problems. The main reason for retarding the transmission of water vapor through the building envelope is to prevent water vapor from condensing within the building structure cavities. The Griffolyn® vapor retarder system’s low permeance keeps moisture from infiltrating the building envelope.
