Windows in Białystok — uPVC, Aluminium and Roof

What Windows Does Pro-Plast Offer?

At Pro-Plast in Białystok you'll find three main types of window — we match them to what you want to achieve, not the other way round. The common denominator is sound specs: 6-chamber profiles, triple glazing at Ug = 0,5 W/m²K and a warm-edge spacer.

uPVC windows are the most common choice for houses and flats — warm, quiet and sensibly priced. We have several lines with different Uw ratings, so we'll match a window both to your budget and to your energy requirements. We set out the line details, specs and hardware on the uPVC windows page.

Aluminium joinery comes into play with large glazed areas and shopfronts — slim, rigid profiles will carry more glass than uPVC. It's a material built to last, resistant to sun and moisture, common in shops, offices and modern homes. More on the aluminium joinery page.

Roof windows are the foundation of a liveable loft — they let in more light than a wall window and properly ventilate a room that heats up fast in summer. What counts here is warm fitting and the flashing, because a roof window works in harsher conditions. See roof windows.

Energy-Efficient Windows — Keeping the Heat Inside

In Białystok and across the Podlasie region winters can be long and bitter, and the heating season drags on for months. Here energy-efficient windows are no luxury — they are simply a smaller bill for half the year.

Our warmest uPVC windows reach a whole-window coefficient of Uw from just 0,78 W/m²K, and all of them run on triple glazing at Ug = 0,5 and a warm-edge spacer. In practice a warmer window means not only a lower bill, but also no cold draught off the glass and less water on the sill in winter — you feel the difference in the very first winter after replacing old joinery.

Which window gives you the best ratio of price to savings depends on the wall, the orientation and the budget. We compare specific lines and their specs on the uPVC windows page, and at the quotation stage we'll work it out for your home.

Why Pro-Plast — Fitting, Instalments and a 5-Year Warranty

Even the best window, badly fitted, stops being the best window. Poor foam, a frame set out of true or skipped insulation where it meets the wall, and the draughts come through despite the fine figures on the label. That is why we take fitting just as seriously as the product itself.

• Free on-site survey — we come out, measure up and check the fitting conditions.
• Free written quote — specific solutions to suit your budget, with no obligation.
• Fitting by our own crew — with care for the seal and the finish, plus delivery.
• 5-year warranty and instalments — branded profiles, and the purchase can be spread over time.

We are a Białystok firm with real experience in joinery — we don't vanish once the windows are in. Once they're fitted, it's worth thinking about window sills, roller blinds and insect screens too, which we'll match in a coordinated palette. Have questions or want a firm price? Book a free survey.
