Vapor Barriers

vapor barrier is an important component in building construction. Its purpose is to help prevent water vapor from reaching building walls, ceilings, attics, crawlspace, or roofs, where it can condense and cause building materials to rot or grow mold. Contact a member of our team via Live Chat to know more about the vapor barrier.
