175mm x 3mm Window Cappit Board

This 175mm deep and 3mm thick window board is used for capping over existing timber or tiled window cills, leaving a clean smooth finish that is great for an area that gathers a lot of moisture. These cills are easy to clean with just a cloth and are very durable.

With a White finish this product is sometimes used as an over-cill or cill extension on external wall insulation projects to extend existing windows cills out beyond the new insulation. 

These are 5m in length, perfect for getting multiple window cills sorted.
