Coastal Sill • Therma-Tru

Continuous treated Pine substrate provides a solid stepping surface and resists rot.
All-aluminum cap and nosing resists corrosion and features an extra-high cap profile to provide improved resistance to wind-driven moisture infiltration.
Integrated removable weatherstrip creates a bumper effect, strengthening its seal with wind pressure.
Extra thick, 14-gauge aluminum approach provides excellent durability and a solid stepping surface.
