Advanced Building Products 3 mm Mortairvent® Rainscreen, 150 sq. ft.
When building exterior walls with stone, stucco, brick, cedar, EIFS, or fiber cement siding, it is important to use an effective rain-screen system that will provide a means for drainage and ventilation. Moisture will find its way into these wall systems by way of cracked mortar joints, gaps or cracks in the surface of the material. Natural absorption of the wood or fiber cement also needs to be considered. Once this moisture penetrates the outer surface of the wall, it becomes trapped in the wall system with no way to escape, creating the perfect environment for toxic mold growth and possible structural failure.
Mortairvent® is a drainage and ventilation system specifically designed for use with most exterior siding materials.
- Helps reduce the risk of mold or mildew
- Minimizes staining, peeling and blistering of exterior finishes
- Contributes to LEED points

Apply a weather resistant barrier over sidewall sheathing. Note: some regions may require two layers of weather resistant barrier. Check local codes for more information.
Install Mortairvent® after windows and doors have been properly installed and flashed
Starting at the base of the wall, unroll Mortairvent® from right to left with the fabric flap on the bottom. The blue geomatrix should be facing the weather resistant barrier and the filter fabric facing the exterior of the building.
Staple or nail every three square feet.
On the bottom and top course only, fold the fabric flap and tuck it between the (blue) polymer matrix and the weather resistant barrier to create an insect screen. The top course roll will need to be inverted to achieve this.
On subsequent courses, butt the blue polymer material together without overlapping. Pull the fabric flap over the previous course (shingle style) and staple.
Apply lath, scratch coat, and stucco or masonry veneer siding over Mortairvent® using recommended fasteners and spacing.
