We can supply MDF window boards (also known as window sills) in depths of 18mm and 25mm. Simply choose which size you require when on the product page.

Our MDF window boards are primed all over. If you're worried about the effects of moisture on the MDF, worry no more! All of our MDF is now moisture resistant HDF no matter what size or length you choose.

MDF and HDF are materials made to last. You might just be looking to create as an ordinary window cill but you can also use our window boards as window seat boards - great for a view spot over a flourishing garden.

We are able to produce custom sizes (length and width) as we offer a bespoke service so if you need the window board cutting to a different size, simply drop us an email and we'll get back to you as soon as possible.
