Outsulation MD System Highlights
The drainage channels present in Outsulation MD will evacuate "incidental" water that, for a variety of reasons, may find its way behind the EPS insulation. Water Resistive Barriers (WRBs) prevent this moisture from coming into contact with the substrate as it drains. All Dryvit WRBs are classified in Canada as a Type III air barrier, but offer a range of vapour permeability from highly permeable Backstop NT, to Backstop NT-VB's vapour barrier performance allowing the designer to balance exterior wall system properties with the building's mechanical and interior climate controls. Dryvit WRBs are an essential element of the Outsulation MD System.
