Building Envelope Systems

Control Moisture Movement with Our Patented Technology

W. R. MEADOWS has been helping building owners, designers, and contractors fight off the ravages of moisture infiltration for over 95 years. The W. R. MEADOWS system of moisture protection products is designed to work from the ground up to provide you with the best available defense against moisture infiltration for the building envelope.

Since the products were developed to work together by one company, all products are compatible and constructable. We provide vapor barriers/retarders, waterproofing, and air and vapor barriers for all your building envelope design needs. For building envelope systems, W. R. MEADOWS has the perfect product to protect your investment for years to come.

Air Barrier White Paper

The rationale for non-permeable air barriers (fluid-applied or self-adhered sheet) is based on a number of factors. The most notable of these is the code-driven mandate for exterior continuous insulation in many climate zones. This white paper explains how this decision is made based on many factors, including insulation, the International Building Code, climatic conditions, etc.
