What it's used for
- Finishing internal window reveals in living rooms, bedrooms, and hallways as a neat, paintable sill board
- Replacing damaged or uneven timber window boards where a consistent, knot-free surface is required
- New-build and renovation projects where a factory-primed board reduces on-site preparation time
- Kitchens and bathrooms where humidity levels can cause solid timber to warp or swell over time
Fitting and handling
Allow the boards to acclimatise in the room where they will be fitted for at least 24 hours before installation, keeping them flat and supported along their full length. Fix using a suitable grab adhesive applied in a serpentine bead to the underside, with mechanical fixings added at each end where the board meets the window frame or plaster reveal. Once fitted, apply a compatible water-based or solvent-based top coat paint to all exposed faces and edges to seal the board fully and protect against moisture ingress.
FAQ
Is MDF window board suitable for kitchens and bathrooms?
This board is manufactured from moisture resistant MDF, which makes it more stable than standard MDF in humid conditions. It is suitable for kitchens and bathrooms provided all surfaces and edges are fully sealed with paint before and after fitting. It is not rated for external use or direct water contact.
What is the difference between a bullnose and a square-edge window board?
A bullnose profile has a rounded front edge that softens the appearance of the sill and reduces the risk of chipping at the leading edge. A square-edge board has a sharp 90-degree front edge. Bullnose boards are the more common choice for painted interiors across new-build and renovation projects in the UK.
Can I cut this MDF window board to length on site?
Yes. MDF cuts cleanly with a fine-toothed hand saw or circular saw. After any cut, seal the exposed MDF edge with primer or paint before fitting to prevent moisture absorption. Nottage Timber Merchants also offer cut-to-size options, so contact us if you need boards cut before delivery.
