Therma-Tru Sills

Hardwood Adjustable Sill

  • Continuous moisture-resistant treated Pine substrate provides a solid stepping surface and resists rot.
  • Durable hardwood cap and nosing stands up to wear and can be stained to match the door and trim.
  • High-dam, narrow cap mates with the dual-bulb bottom sweep to help deflect moisture away from the cap; engineered U-shaped weather seal creates an added barrier against wind-driven moisture infiltration.
  • Flush-fitting zinc dichromate screws form an uninterrupted sealing surface, resist corrosion, and adjust the cap vertically to help maintain a tight seal over time.
  • Thick, 15-gauge aluminum approach provides excellent durability and a solid stepping surface.
Adjustable for long-lasting performance.
Genuine Therma-Tru sills are engineered with features to help minimize the potential for leaks and drafts. Our adjustable sills allow flexibility to adjust the sill cap vertically to close gaps over time, helping to maintain a tight seal between the sill and bottom of the door.
