Deeplas White Square Edge Capping Board – 400mm x 5m

The Deeplas White Square Edge Capping Board is engineered specifically for fast, efficient refurbishment projects where structural timber replacement isn’t required. These exceptionally wide, premium square edge capping boards are used to cover existing deep fascias which are tired or worn, completely transforming large or deep weathered rooflines into a pristine, contemporary feature. Manufactured from high-quality, calcium-organic PVC-u, the P1030 board is completely weather-resistant, meaning it will never rot, warp, or require painting.

Please note that capping boards must be fixed directly to structurally sound timber backing. If your existing timber is decayed or you require a more heavy duty application, you should check out our selection of full-replacement Fascia Boards. Otherwise, you can view our full range of alternative sizes and finishes in our parent capping boards category.

Premium Deep Window Sill Cover Board

In addition to being a fantastic product for extra-deep exterior roofline use, the massive 400mm profile of this Deeplas board makes it a perfect deep window sill cover board. When utilized indoors, it effortlessly caps over unusually wide, stained, or damaged internal window cills, providing perfectly clean lines and stunning modern visuals across large surface areas. The robust uPVC skin creates a durable, impact-resistant surface that completely eliminates the need for sanding, priming, or painting—requiring nothing more than a quick wipe down to maintain its bright white finish.
