Sill Pan Flashing: Protect Your Walls From Water Damage

Sill pan flashing is a type of metal flashing installed at the base of a window or door to prevent water from seeping into the wall cavity. It is typically made of galvanized steel or aluminum and is bent into a U-shape to fit around the window or door frame. The flashing extends out over the exterior siding and down over the sill, creating a weather-tight seal. Sill pan flashing is an essential component of a properly installed window or door system and helps to prevent water damage to the building’s structure.
