The Importance of Rainscreen Technology:What is a rainscreen? A rainscreen is a pressure-equalized airspace between the structural envelope and the exterior cladding that promotes drainage of moisture from the wall system. Rainscreens were designed to allow the moisture to "drain, not remain". The air pressure difference across the exterior cladding is a significant force causing the infiltration of air and water on windward facades. The equalization of this pressure neutralizes the forces that draw moisture into the assembly. Manufactured at our Geotextiles Facility, we recently redesigned Mortairvent to be manufactured from 40% recycled content qualifying it for LEED credits. We have also increased the compression strength of Mortairvent allowing for better ventilation and drainage as compared to other products on the market.Why Mortairvent?Our innovative rainscreen technology equilizes the air pressure within the wall system by creating a ventilation cavity between the weather resistant barrier (WRB) and the exterior wall. The polymore-core mesh creates the airspace while the filter fabric blocks mortar from seeping into the newly formed cavity. This design allows excess moisture to drain and not remain in the wall system.
