Drainage Products to Keep Outboard Insulated Walls Dry

Rigid outboard insulation can range from being very porous to virtually waterproof. These characteristics must be known and the exterior building envelope designed to provide for them. This is no easy task, and it involves significant understanding and careful design.

Designing an exterior building envelope that may have two or more layers of boardstock materials that can range from porous to virtually waterproof and that may be vapor retarders under various conditions, carries a significant risk.

A  gap created by the MTI’s Drainage Planes and Drainage Strips keeps Rigid Boardstock Insulation applications assemblies dry.
