There is nothing that lets a room down more than a stained or damaged window board. Our White UPVC Window Board and Sill products are designed to lift the look of your home and reduce maintenance. They offer unbeatable value while delivering robust performance. Available in a range of clean-edged and rounded styles, as well as a choice of sizes, they are stylish and practical. You will benefit from an internal window board and sill system that is scratch and stain resistant for durable good looks. Unlike wood, these products won’t rot, shrink or warp. They are sealed for protection against moisture and come with a long manufacturer’s guarantee.
Perfect for any room in the home or office, our White Window Board and Sill is stocked in Square and Bullnose profiles. They boast a smooth gloss finish, and are manufactured from robust UPVC . The products in this range can easily be trimmed to size and they can be installed with little effort. They will never need sanding down or painting and only require cleaning.
We recommend these products if you want a cost-effective, hassle-free window board and sill solution. For your convenience, we stock matching end caps for a flawless finish.
We stock White Window Board & Sill in the following profiles:
All the products benefit from a Class 1 fire resistance rating. They are also UV stable, meaning they won’t fade or discolour. In fact, they will look as good as new for years. The UPVC profiles are non-toxic and fully recyclable.
We recommend the square window board and sill if you want to achieve a clean-edge finish. For a more curved look, opt for the bullnose UPVC window board and sill. To guarantee your complete satisfaction we ensure both of these products are dispatched with a protective film.
Ensure you choose the right size product for your project - simply click on the correct length measurements in the drop-down menu on product pages.
We deliver White Window Board & Sill across whole of the UK mainland. We dispatch and deliver profiles in as little as 1 to 3 days, no matter where you are. Buy online today and discover our brilliant UPVC products, prices and customer service.

“Very impressed this time around!!! (disappointed with communication and delivery in first lockdown) and left a negative review which I updated after delivery. I can now understand all the good reviews before the pandemic. Still the cheapest by far and the products are spot on. I've just placed another order - Thank you keep up the good work” Jason Wright | ![]() |
