"How much does a window cost?" is the most common question we get — and the only one that cannot honestly be answered with a single number. Two windows of the same size can differ in price by a factor of two, without any sleight of hand. Below we break the price down into its parts, so you know what you are paying for and where the real savings are.
Why there is no "price per metre"
The price of a window does not grow in proportion to the glass area. The most expensive elements — hardware, gaskets, welds and labour — sit around the perimeter and in every sash, not in the middle of the glass. That is why one large window is usually cheaper than two small ones with the same total area, and a window with three sashes costs noticeably more than a fixed window (FIX) of the same dimensions. Price lists "from X zł per m²" describe the simplest white window in the cheapest system — a real order almost never looks like that.
1. Material and profile system
The reference point is uPVC — the best price-to-performance ratio. Timber and aluminium at the same dimensions come out higher, but they are bought for other reasons: timber for a natural interior, aluminium for very large glazing and slim profiles. Within a single material the differences are considerable too: a 76 mm uPVC profile with external sealing (AD) is the standard; the MD version with a centre gasket and depths of 82–88 mm are the next steps up — each with better insulation and a higher price.
2. The glass unit
The glass is usually the largest single item in a window. Moving from a double-glazed to a triple-glazed unit raises the price, but also lowers the Uw of the whole window and is today's standard in new homes. Then come the options: a warm-edge spacer instead of an aluminium one, safety glass (toughened or laminated), acoustic glass, solar-control glass. Each makes sense in a specific place — laminated glass on the ground floor, acoustic on the street side, solar-control on a south-facing terrace — and none makes sense everywhere.
3. Size, layout and opening type
A fixed window (FIX) is the cheapest, because it has no sash and no hardware. Tilt-and-turn is the standard. Balcony doors, windows with a low threshold and above all HST lift-and-slide doors are a different price category altogether — heavy sashes, rollers, tracks and glass of large area. If the budget is tight, the simplest saving is fewer sashes: in a wide window, one opening sash plus a fixed section instead of two sashes.
4. Colour
White is the base price. A woodgrain foil or a RAL colour is a surcharge — one rate for one side, another for two. A two-tone version (for example anthracite outside, white inside) is usually more sensible than colour on both sides, and looks identical from the street. In aluminium the RAL palette is wide, and the price depends on the type of coating (matt, gloss, textured).
5. Extras that are easy to overlook
Trickle vents, lockable handles, RC2 class security hardware, concealed hinges, sills, roller shutters — inexpensive individually, together they can add up to a lot. It pays to put them on a list from the start, so you compare quotes with the same content, not a "window" against a "window plus ten options".
6. Transport and unloading
Windows travel on racks, and the cost of transport depends on distance and order size — not on the number of windows. That is why shipping a single window is disproportionately expensive, while a full set for a house spreads that cost across many items. This is precisely why we accept orders from 2 windows or 1 HST door. For Germany, the Netherlands or Belgium we quote transport individually based on the address.
What "without installation" means and why it pays off
Buying windows without installation, you pay for the product — without the installation company's mark-up on the goods. You arrange installation locally, with a team you choose yourself and pay for the work, not for the windows. For the investor this means two clear invoices instead of one "package" where nobody knows what costs what. There is also a tax reason: when replacing windows in your own, occupied home, under the thermal modernisation relief you deduct the real purchase cost — up to PLN 53,000 per person. This is general information, not tax advice; confirm the details with your accountant.
How to compare two quotes so you compare the same thing
- The same specification. Dimensions, layout, opening type of every pane, glass unit, spacer, colour, hardware — point by point.
- Uw of the whole window, not of the glass alone (Ug) or the profile (Uf). The manufacturer states it in the Declaration of Performance — we explain how to read it separately.
- What is included in the price: transport, racks, sills, handles, documents for the country of delivery.
- Lead time and payment terms. A deposit on ordering is the norm, because windows are made to measure; the balance before or on delivery.
- Warranty and service. Who provides it and where, if a sash needs adjusting after two years.
How to get a firm price
We do not publish prices online, because every configuration is priced by a person who knows these systems — and who answers with a firm quote, not a price range. Build your window in the configurator: material, system, dimensions, layout, opening, glazing and colour. You can add several windows to the project and ask for a quote in two systems at once, to see the difference on your own example. We reply within 48 hours.
