Product Details

Our new wide windowboard product designed to help create a feature window in any room, providing a place for those special momentos and framing views out into gardens and outdoor spaces. 

The new wide window board comes in a white primed finish and has a bull nosed profile with a flush back edge, so it can cut it down to suit different wall thicknesses.

Measuring 25mm x 350mm x 3,660mm, the wide window board is also being brought to market to give tradespeople a window board that can be installed with windows on external walls fitted with extra insulation to meet the latest building regulations and which, as a result, are thicker than they would have been previously. 

Allow Size Instructions Yes
Feature Moisture Resistant MDF. White Primed ready for undercoat and gloss finish. All sizes shown are finished sizes
Fitting Instruction If you are fitting an MDF Window Sill from The Skirting Board Shop, all you need to secure the product is a strong adhesive. We also recommend using an adhesive if you have opted for a stained finish. This is a quick and easy installation process which removes the decoration required to hide nails or screws. But if you are finishing the product with paint, then simply follow these steps to correctly fix it in place: Pre-drill holes to prevent splitting or damaging the wood Put the skirting board in place Drill in finishing nails so they are just below the surface of the wood Use an adhesive to strengthen the fixing if required Apply a finish to the nail heads to match the rest of the sill
