Worthington louvers should be installed with
galvanized fasteners and urethane adhesive. Most
commonly the louvers are secured through the brick
molding. The urethane adhesive should be applied in
a ¼” bead about 3/8” from the outside edge of the
louver and squeezed out to the edge and act as a
caulk and sealant to prevent water seepage when the
louver is secure with fasteners.
All open louvers may allow water seepage during
severe weather conditions. Worthington recommends
installing a flash pan to catch any water seepage.
This can be fashioned out of sheet metal or coil
stock and fastened in position before louver
installation.
When ordering a louver that's open with
screen, a noncorrosive screen backing is
attached so that insects and the like are kept
out, while allowing air to flow through
