Mortairvent® CW is our all-wall mortar deflection system for cavity wall construction that creates a clear drainage & ventilation space while maintaining the code minimum one-inch airspace. Our design gives specifiers and contractors more options from one manufacturing source.

Applications

For use as an all-wall mortar deflection. The gray filter fabric acts as a mortar diverter, which allows moisture, but not the mortar, to drain down the wall via the molded polymer core geomatrix design. With the proper installation of weep vents at all flashing locations, Mortairvent® CW will create an unobstructed clear path for moisture removal.

Features & Benefits

  • The unique configuration provides uniformity and structural integrity which will stand up to the weight of the mortar.
  • Mortairvent® CW, with the use of proper top and bottom vents, turns a drainage wall into a drained and ventilated rainscreen wall design.
  • Will not rot or react with common building materials.
  • Requires no adhesives, fasteners, or special skills to install.
  • Meets NFPA 285 Criteria.
  • 25-year warranty.

Apply a water resistant barrier over sidewall sheeting. Check local building codes and specifications for more information.

Install Mortairvent® CW over installed rigid foam insulation board. Starting at the base of the wall unroll Mortairvent® CW from right to left between brick anchors with the three-dimensional (blue) polymer matrix side against the water resistant barrier and mortar deflection fabric facing exterior of building. Unroll the next course in the same manner as the first.

Be sure to always butt the blue polymer material together without overlapping.
Mortairvent® CW should be installed horizontally between brick ties as exterior brickwork is completed so as to maintain captivation within the brick anchoring system.
