Worthington Louvers – Installation Instructions

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 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.
