Mortar Trap™ Weep Vents

A 100% recycled polyester plastic non-woven mesh vent which is treated with a flame retardant and ultra-violet inhibitors. Used in vertical joints between brick masonry in masonry wall construction to provide for the drainage of moisture and promotion of air flow. The weep vents also prevent insects from entering through the openings.

Installation: Install the weeps in vertical joints ( head joints) of the brick masonry every 24 inches at the flashing level for moisture evacuation and air flow. Weeps should be installed at both the top and the bottom of the wall for equalization of air pressure.
