There is nothing worse than stained or damaged window board. They can really let your home down and spoil the look of an entire room. Our Black Ash UPVC Window Board and Sill products are manufactured to lift the look of your home and reduce maintenance. They offer unbeatable value while delivering outstanding performance. Available in a range of clean-edged and rounded styles, as well as a choice of sizes, they are elegant and practical. You can benefit from an internal window board and sill system that is scratch and stain resistant for long-lasting good looks. Unlike wood, these products won’t rot, shrink or warp - even though they look just like timber. They are sealed for protection against damp and come with a long manufacturer’s guarantee.
Perfect for the home or office, our Black Ash UPVC Window Board and Sill is stocked in Square and Bullnose profiles. They boast a realistic-looking wood grain-effect finish that is both stylish and contemporary. The products in this fast-selling range can easily be trimmed to size and they can be installed quickly with minimum effort. What’s more, they will never need sanding down or staining and only require cleaning.
We recommend these products if you want a cost-effective, wood-effect window board and sill manufactured from an ultra low maintenance material. For your convenience, we stock matching end caps for a perfect finish.
We stock Black Ash Window Board & Sill in the following profiles:
All the products benefit from a Class 1 fire and flame resistance rating. They are also UV stable. This means they won’t fade or discolour and have been tested to ensure they are colour-fast. In fact, they are manufactured to look as good as new for years. Our UPVC profiles are non-toxic and fully recyclable.
We recommend the square UPVC window board and sill if you want to create a clean-edge finish. For a more rounded feature, opt for the bullnose 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.

“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 | ![]() |
