The Mortairvent CW and Mortairvent RFI products introduce the benefits of rain screen technology (mortar deflection, moisture drainage, and ventilation) to full masonry cavity wall applications. The Mortarvent CW system features a nonwoven, mortar deflection fabric bonded to a 1/4-, 1/2-, or 3/4-in. polypropylene mesh designed to keep the entire wall cavity clear from mortar droppings and debris. Mortairvent RFI adds a thermal insulation feature to Mortairvent CW as the product is factory adhered to rigid foam insulation panels in 16-in. widths designed to fit between the brick ties in full cavity wall applications.
