Sills, Bottom Sweeps, Sill Pan & Sill Covers Genuine Therma-Tru ® sills and bottom sweeps help form a tight seal against wind-driven moisture infiltration at the bottom of the door system and help channel moisture away from the home. The sill pan (recommended) adds an extra layer of protection to help keep moisture away from the subfloor. Inswing Sills Designed to mate with our inswing bottom sweeps to help seal the margin between the door and sill. Help channel moisture away from the home with a 6-degree sloped ramp. Help provide a solid stepping surface with a slip-resistant tread pattern on the approach. A thermal break helps stop cold and heat from traveling through the sill and forming condensation inside the home. Offered in a variety of materials with features to meet the needs of different climates and exposures. See finish options on page 18.
