Installation Guides

Helpful Hints

• Ganged Windows—Multiple window units should have a continuous piece of DamSill under the mullion (joint between the two windows).  These areas frequently leak and a continuous piece of DamSill will catch the water.
• Windows With EIFS Accents—The DamSill can be installed on windows with up to a 1” accent without modification. Accents over 1” must be cut at an angle to allow the DamSill drain holes to reach the outboard surface.
• Caulking The Window—All windows and window perimeters should be sealed.  The construction elements of many windows and doors leak.  These areas should be caulked to help prevent leaking.
