Vapor Barrier for Reliable Moisture Protection

Moisture Protection That Helps Preserve Your Structure

A vapor barrier is a membrane, typically made of polyethylene plastic (Tyvek), designed to resist the diffusion of water vapor through building assemblies like walls, floors, and roofs. Its primary purpose is to prevent interstitial condensation by stopping warm, moist indoor air from reaching cold surfaces where it would otherwise condense into liquid water.

Key benefits include:

Moisture Protection: It prevents mold growth, mildew, and the deterioration of structural components like wood framing and insulation.

Energy Efficiency: By keeping insulation materials dry, it preserves their thermal resistance, reducing heating and cooling costs.
