Moisture Protection in Masonry Walls

Advanced Building Products is serious about being an active member of the architectural community that supports and in turn specifies our extensive variety of moisture management products.

Mortairvent
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.
Waterproofing Membranes - Moistseal
Moistseal is a polyvinyl chloride sheet available in 10, 20, 30 and 60 mils. It will show no cracking or flaking when bent through 180 degrees over a 1/32" mandrel and then bent at the same point over the same size mandrel in the opposite direction through 360 degrees. The material conforms to A.S.T.M. Standards D-822 for at least 400 hours. Strict quality control assures full weight and uniform thickness.

Manufactured stone, EIFS & stucco are extremely popular home exterior coverings. Despite their considerable durability hairline cracks will form, most frequently in the mortar joints. These cracks are especially common in parts of the country that experience frequent freeze/thaw weather patterns. These hairline cracks allow wind-driven rain to penetrate the mortar and collect within the interior wall. Once the moisture gets in it has nowhere to go thus creating the perfect environment for toxic mold growth.

Mortairvent® is a two-ply mortar deflection and ventilation system that had been specifically designed for use with manufactured stone, stucco, EIFS and brick. By installing the Mortairvent® two-ply system, a ventilation cavity is created between the vapor barrier and exterior wall. The blue polymer core mesh creates the airspace, while the filter fabric blocks mortar droppings from seeping into this newly formed cavity, while still allowing moisture to pass through. The combination of drainage and ventilation eliminates the threat of toxic mold.
