Vapor Barriers and Vapor Locks

Vapor Locks are created by applying a vapor permeable flexible material that is affixed directly behind cladding and under roofs. The material allows air to flow through but not moisture.

What is a Vapor Lock?

Vapor locks are a performance adhesive, moisture control and sound reduction membrane.

After the insulation is in place a vapor barrier prevents water vapor from diffusing into the wall, ceiling or floor during the cold winter or heavy rainy seasons.
