uPVC windows — compare companies' offers independently
uPVC (PVC) windows are window units made from a steel-reinforced PVC profile with a glazing unit; they are chosen for warmth, quiet, durability and an affordable price. On OKNA.ua you compare uPVC windows from many verified companies across Ukraine at once — independently, in one catalogue — and choose by price, profile, glazing unit and lead time.
OKNA.ua is a niche portal about windows only, with over 25 years of expertise — not an everything-marketplace: it lists specialist window companies, so you see an independent comparison of the market rather than one seller's pitch. Manufacturing to your sizes, measurement, delivery, installation and warranty are handled by the company you choose.
How to choose a uPVC window: profile, glazing unit, opening
Warmth, quiet and price are set by three things — the profile, the glazing unit and the opening type. Below are honest pointers on when each option fits; compare specific configurations from different companies in the catalogue on this page.
uPVC profile by chamber count
| Profile (frame depth) | Chambers | When to choose |
|---|---|---|
| 58–60 mm | 3–4 | Base frame: balconies, non-living spaces, standard apartments in warm regions, a moderate budget. |
| 70 mm | 5 | The all-round choice for apartments and houses — the best balance of warmth and price. |
| 80–92 mm | 6–7 | Maximum energy efficiency: detached houses, cold regions, ground floors, panoramic glazing. |
The greater the frame depth and the number of chambers, the better the profile retains heat — and the higher the price. In Ukraine, uPVC windows are made to ДСТУ EN 14351-1:2020 ("Windows and doors — Part 1: Windows and external pedestrian doorsets"), in force from 01.02.2021 in place of the former ДСТУ Б В.2.6-15:2011, and PVC profiles to ДСТУ Б В.2.7-130. The standard also sets the window's heat-transfer coefficient Uw, W/(m²·K): the lower it is, the warmer the window (Uw describes the whole window, while Ug describes only the glazing unit).
Glazing unit: warmth, noise, price
| Glazing unit | Build | What it gives |
|---|---|---|
| Single-chamber | 2 panes, 1 cavity | Lighter and cheaper; base warmth — for balconies, non-living spaces and warm regions. |
| Double-chamber | 3 panes, 2 cavities | Warmer and quieter; the default choice for homes in most regions. |
| Low-E (i-glass) | energy-saving coating | Reflects heat radiation back into the room — lower heat loss in winter. |
| Argon | inert gas in the cavity | Improves the unit's insulation compared with an air fill. |
| Multifunctional glass | selective coating | Also reduces solar overheating in summer — for sunny facades. |
Opening types
| Type | How it works | When to choose |
|---|---|---|
| Fixed | does not open | Cheapest; for shopfronts and upper sections, but harder to clean from outside. |
| Turn-only | swings open sideways | Simpler, affordable hardware; where tilt ventilation is not needed. |
| Tilt-and-turn | sideways + tilt for ventilation | The all-purpose standard for homes — easy draught-free ventilation. |
| Sliding | slides sideways | Saves space; for balconies, loggias and terraces. |

What the price of a uPVC window depends on
There is no single per-window price — the cost is calculated individually for your opening, so the catalogue shows "from" prices. The total is driven by:
- Profile — chamber count (60/70/80–92 mm), frame depth and the brand of the system.
- Glazing unit — single- or double-chamber, with or without Low-E (i-glass) and argon.
- Size and number of sashes — a fixed section is cheaper than a tilt-and-turn one.
- Hardware — basic, with micro-ventilation or anti-burglary.
- Colour and lamination — a white window is more affordable than woodgrain or RAL lamination.
- Survey, removal and installation — fitting, removing the old window, reveals, a sill and waste disposal are counted separately.
- Floor and access — height and the need to hoist large units.
A per-m² price is only a guide for comparison: a small window usually costs more per m² than a large one. Compare like-for-like configurations from different companies independently — and choose by price and lead time. Your chosen company states the exact cost after measuring.

Questions and answers
How much do uPVC windows cost?
There is no single price: the cost depends on the profile (chamber count), the glazing unit, the opening type, the hardware and the opening size, so companies calculate it individually. Compare starting prices from many companies in the OKNA.ua catalogue independently, send a request to the one you choose — and get an exact quote; an online calculator is available for a preliminary estimate.
How do I choose the profile and glazing unit?
Start from the climate, the floor and the noise level: for most apartments people take a 70 mm profile (5 chambers) with a double-chamber glazing unit (3 panes) with Low-E glass and argon; for cold regions and ground floors — 80–92 mm (6–7 chambers). Your chosen company will suggest the best combination for your home once you send a request.
How many chambers does a profile need?
For warm regions and standard apartments, 3–4 chambers (58–60 mm) are enough; the all-round choice is 5 chambers (70 mm); for maximum energy efficiency, cold regions and ground floors, 6–7 chambers (80–92 mm) are used. More chambers mean a warmer window but a higher price.
Why are uPVC windows better than wooden and aluminium ones?
uPVC windows give the best balance of warmth, price and upkeep: they are cheaper than wooden ones and warmer than non-thermal aluminium, need no painting and resist moisture. Wooden windows are natural and prestigious but cost more; aluminium is stronger for large structures and facades, and warm systems with a thermal break cost more. For homes, PVC is most often the optimum.
What does the price of a uPVC window depend on?
The price is affected by the profile (chamber count and brand), the glazing unit (single-/double-chamber, Low-E, argon), the size and number of sashes, the hardware, the colour and lamination, and the survey, removal and installation. A per-m² price is only a guide, since a small window costs more per m² than a large one. Your chosen company calculates the exact figure after measuring.
What warranty do uPVC windows have?
The warranty is provided by the company you choose — the manufacturer or seller — separately for the profile and glazing unit, the hardware and the installation; the exact terms are stated by the company in the contract. So we recommend comparing not only the price but also the warranty terms of several companies in the OKNA.ua catalogue before ordering.
How long do uPVC windows last?
Service life depends on the quality of the profile and hardware, correct installation and maintenance. With proper use, quality uPVC windows last for decades; the hardware needs occasional servicing (lubrication) and the seals may eventually need replacing. Check the exact warranty and service terms with your chosen company.
To which standard are uPVC windows made in Ukraine?
uPVC windows are made to ДСТУ EN 14351-1:2020 ("Windows and doors — Part 1: Windows and external pedestrian doorsets"), in force from 01.02.2021 in place of the former ДСТУ Б В.2.6-15:2011, and PVC profiles to ДСТУ Б В.2.7-130. The standard also sets the window's heat-transfer coefficient Uw. Verified companies in the OKNA.ua catalogue work with profiles and glazing units that meet these requirements.
