The Model BV is a heavy-duty extruded aluminum brick vent.  The aluminum construction makes it resistant to the corrosive environment of foundation walls and chimneys.  The brick vent comes with both birdscreen and insect screen.  The brick vent features both extended head and extended sill to provide a drip edge for water to travel around the opening.  there is also a raised water stop at the back to prevent any water flowing into the duct.  It also has structural ribs in the head and sill to provide a good masonary bond.  The brick vent is made from extruded aluminum, is available in custom sizes and is more versatile than a cast aluminum vent.
