PVC window sills
A window sill, also known as a window ledge or window bottom, is the shelf-like, flat piece of window trim found at the base of the window. Window sills are important to the design and functionality of the window.
Sills serve a variety of purposes and functionality:
- Structural Integrity. The rigid sill on the bottom helps eliminate flexing to support the structure
- Improved Energy Efficiency. Provides a barrier for thermal insulation to be installed
- Water Protection. Protects the wall and leads water away from the building when it rains and not into your home
- Decorative Space. Showcase plants, pictures, candles, etc.
