Window Boards
Commonly referred to as internal window sills, window boards are premium MDF surfaces found at the bottom of a window. Although they are typically used to cover the gap between the front wall and the window, they can also divert condensation away from the glazing. In most households, window boards also serve as shelving units for picture frames, ornaments and plants.
- MDF window boards are much easier to work with than real wood. As a man-made product there are no natural imperfections to contend with so you are left with a perfectly smooth finish every time.
- The material we use is an industrial grade, moisture resistant MDF. This is the best quality MDF available and ensures our window boards are highly durable and will last over time.
- Order a tongue for maximum installation convenience. The standard tongue size is 9mm x 9mm on an 18mm window board, 12mm x 12mm on a 25mm board and 15mm x 15mm on a 30mm board.
