Material Specifications
Manufactured from a polyvinyl chloride compound specifically designed for continuous exposure to weathering.
Compound possesses excellent sunlight resistance, good low temperature properties and contains a polymeric plasticizer to ensure performance.
Features
Top-flap – overlaps two adjacent bricks to stop mortar from falling into air passage.
Flexible wings – To adjust to variation in mortar joint widths (5/16” – ¾”)
Louvers – To allow air passages while creating a water barrier.
Water ridges – When water buildup on the exterior wall surface is blown into the air passage, these ridges create a barrier which directs the rain down and out of the cavity.
Williams-Goodco Brick Vents
The Williams-Goodco brick vent is an injection molded vent made from flexible polyvinyl chloride in an offset “T” shape. When inserted in vertical mortar joints between two bricks, the slotted leg of the vent allows air to SOMETHING in and out, while allowing water to weep out. It also prevents water from penetrating in.
Comes in light gray.
