What are softwood window boards? Softwood window boards are usually found under a window and are sometimes called windowsills. In our range of internal window boards we have rebated softwood and primed MDF window boards, all available in different sizes depending on what size you need.

Our rebated softwood window boards are made from high quality wood and have been kiln dried for increased stability. Each window board is made from slow grow timber which improves strength and durability.

Each piece of primed MDF window board in our range is easy to work with and has full FSC® chain of custody certification. Every single piece is also supplied in long lengths, reducing wastage costs.

Head down to your local branch to pick up all the internal window board supplies you need. Make sure you take a look at our full timber range for any other products you may need to complete the job you’re working on.
