uPVC Window Sills in Białystok — Internal

What Is a uPVC Sill Made Of?

An internal uPVC sill is the most popular choice for interiors — economical, practical and resistant to everyday use. The core is made of high-impact polyvinyl chloride and laminated with high-quality uPVC veneers, so the surface is smooth, uniform and easy to keep clean.

The material resists moisture, staining and typical cleaning agents, so the sill works well even where it is wiped down regularly. It is a solution that looks good from day one and needs no special care. In Białystok and across Podlasie, uPVC sills are our most frequently ordered internal option.

What Colours and Finishes Are Available?

You can match a uPVC sill to the colour of the window and the whole interior. There is a wide range of veneers to choose from — from classic white to wood-effect decors that warm up a room and go with floors or furniture.

We cut the sill to any length, and the end caps come in the colour of the sill, so the whole thing looks consistent. During transport and fitting the surface is protected with a film. uPVC sills are compatible with uPVC, timber and aluminium windows, so we'll match them to any joinery — including the uPVC windows in our range.

• Wide range of veneers: white and wood-effect decors.
• Any length, end caps in the colour of the sill.
• Protective film during transport and fitting.
• For uPVC, timber and aluminium windows.

Choosing and Fitting a uPVC Sill

Choosing a uPVC sill starts with a free on-site survey. We check the depth of the recess, the width of the window and what the sill has to cope with day to day — only then do we talk about colour and overhang. A sill is best planned together with replacing the joinery, because then the dressings and fitting come out clean, with no touch-ups.

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 a uPVC 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.
