In mixed climates, where homes that heat in the winter and cool in the summer, homes using traditional polyethylene vapor retarders may actually trap moisture in the cavity during the summer. This raises the risk of costly moisture and mold issues, structural damage, health consequences, and liability.

When insulating our new homes, we use CertainTeed MemBrain to prevent water vapor from getting trapped in the wall cavities. This leading edge product allows moisture to escape during humid summer months and blocks moisture from entering the walls during cool winter months.

CertainTeed MemBrain provides a balanced moisture level, creating a comfortable living condition.
