Cast Aluminum Brick & Block Ventilators are made of high corrosion resistant alloy #319. All castings come with aluminum insect screen with 7 x 7” mesh. The block ventilators are designed with a deep louvered face and a continuous water stop set far back on the inside of the casting, a combination that prevents water from entering the building. There is a drip at the top and bottom of the casting to prevent water staining or sprawling of the brick.
