MDF Window Sills in Białystok — Waterproof
An MDF sill is a good compromise between a warm, wooden look and resistance to moisture. The waterproof wood-based board gives a smooth surface and durability for years — it works where you want wood in the climate, but without its fussiness.
What Is an MDF Sill?
An MDF sill is a wood-based product made by pressing wood fibres. Unlike an ordinary board it is waterproof, which makes it suitable for the window area, where moisture and condensation can occur.
MDF gives a smooth surface and a warm, wooden look that warms up a room and goes with floors, furniture and joinery. It guarantees durability for many years while staying easy to keep clean. It is a solution for interiors — for people who want the effect of wood without its sensitivity to water. In Białystok and across Podlasie, MDF sills are usually chosen for living rooms, bedrooms and other rooms.

MDF or uPVC — Which to Choose?
An MDF sill and a uPVC sill are two popular options for interiors, but they give a different effect. MDF goes for a warm, wooden look and a solid, smooth finish — it is chosen by those who want the natural aesthetics of wood. A uPVC sill is the most economical and comes in the widest range of veneers, including wood-effect decors.
Both are for interiors and both stand up well to everyday use. If you want the effect of wood with water resistance, choose MDF; if price and the choice of colours matter most, take a look at the other window sills. MDF is compatible with uPVC, timber and aluminium windows, so we'll match it to any joinery — including new uPVC windows.

Choosing and Fitting an MDF Sill
Choosing an MDF sill starts with a free on-site survey — we check the depth of the recess, the width of the window and the style of the interior, then we choose the colour and finish. A sill is best planned together with replacing the joinery, so the dressings and fitting come out clean.
We carry out the fitting with our own Pro-Plast crew, and the purchase can be spread over instalments. As a local Białystok firm we give a 5-year warranty. We're glad to combine an MDF sill with new uPVC windows — book a free survey or call 602 488 413. You'll find the other types of sill on the window sills page.
