What Is A Window Board?

Posted by Skirting World on 10th Sep 2018

What Is A Window Board?

A window board is a piece of wood (or in our case premium MDF) that is found underneath a window. They are commonly referred to as window cills.

What are they used for?

A window boards primary use is to cover the reveal at the bottom of the window.

External walls are usually a lot thicker than a window and because they are fitted flush with the outside of the wall, you are left with. a reveal around the window.

A window board fitted on the bottom reveal covers this gap.

Do they serve any other uses?

As well as their main purpose, they do have other uses:

Aesthetically Pleasing

When fitted underneath the window, the reveal itself looks more appealing to the eye.

Generally, the left, right and top of the window reveal are plaster boarded and then plastered. The bottom of the reveal is normally left as brick work or a bare plaster board.

This is why a window board can help make the window reveal look complete.

Can Be Used As A Shelf

In most homes, you'll find various ornaments and picture frames on the window sills.

This is common practise as they are normally wide enough to sit an array of items up on.

What's The Best Material For A Window Board?

You can find window boards made using softwood, hardwood, PVC and MDF. Out of these, we would always recommend MDF as it tends to be the cheapest option and gives the best finish (especially if painting).

Softwood and hardwood window boards can be expensive. PVC doesn't have the same premium look as wood.

Our MDF window boards are made using our premium moisture resistant MDF. If you choose the primed option, you'll be able to apply your final finish straight away.

Do All Window Boards Feature A Bullnose?

When purchasing window boards, you may find that a lot of them are described as being bullnosed. This refers to the front edge of the board being round rather than square.

This helps to make the board look more appealing and also prevents any sharp edges causing harm.

But to answer the question, no. Not all window board feature a bullnose.

You can get hold of square window boards up on request. Companies like ourselves can also add a different shape or design should it be required.

Do Window Boards Always Have A Tongue?

Not as standard. For instance, our window boards will not feature a tongue unless it is requested.

A tongue is used to fit into the groove on the window to help secure the board and keep it in place.

However, it's not a necessity. Window boards can be installed perfectly without a tongue.

Can You Use Window Boards To Make Shelving?

Yes, we've had many customers order them for this purpose. They've also used them to make bookcases.

Our standard sizes may be too big for these uses, but that's why we offer custom and bespoke window boards.

We can pretty much make any size that is needed. If you have a project coming up, just get in touch for a quote.
