The deepest PVC system in our range: 100 mm installation depth, six-chamber frame and sash, exclusively triple 48 mm glazing. With the right glazing the U-value of the window goes down to 0.61 W/m²K, which is passive-house level. This is for those whose first consideration is thermal insulation and whose wall thickness can take the deeper frame.

The section drawing is the manufacturer's official diagram.
The actual U-value comes from the chosen glazing and the size of the unit together, which is why we write it out in the quote, item by item.
With the right glazing the U-value of the window goes down to 0.61 W/m²K. Less heating, lower bills, and better use of solar gain.
The all-round seal and the right glazing together give the sound insulation. On a busy street, thicker glass counts for more than the profile.
The system is prepared for security hardware, so it is not a solution added on afterwards.
Narrow yet rigid profiles, so a larger glazed area fits into the same opening.
Source: the official Gealan system description. The list describes what the system is capable of; which of it applies in your case is decided by the installation situation and the glazing you choose.
We do not publish a price list, because we manufacture to measure and a price written for a standard size would be misleading anyway. What we will tell you is what moves it.
We manufacture to measure. A large, divided, tilt-and-turn unit costs more than fixed glazing of the same size. With several items the unit price is usually more favourable.
Triple glazing costs more than double, and so do safety glass and enhanced acoustic glass. We quote several versions in the offer so that you can see the difference in forints.
Foil-laminated and RAL colour versions carry a surcharge. The strip-out, the installation and the foam sealing are included; the sill and the removal of rubble are separate items. Scaffolding is rarely needed, only where the height calls for it.
The survey is free, and afterwards you get an itemised quote, written out item by item. During office hours this is typically ready within a few hours. Request a quote →
With us window replacement comes from one hand: we take out the old unit, we fit the new one, with fixings every 70 centimetres and foam sealing. You do not have to coordinate two teams.
We give a 5-year guarantee on the installation. We have been working since 2004, with 4816 windows and doors fitted behind us.
If you are planning a refurbishment, it is worth looking at shading at the same time: it means one call-out and one making good. The front door can go into the same quote too.

On the outside the Gealan Kubus ALWAYS gets an acrylic, that is acrylcolor, surface rather than foil. Acrylic is not a layer glued on but a solid colour co-extruded with the profile: it cannot blister or peel, and it lasts better than foil even in dark shades that heat up in the sun. Inside it can be ordered in white or with a foil finish. The acrylic range is narrower than the foil range, so here we show the complete list as confirmed by our supplier.
These are the acrylic colours available. The colour of the outer face can be chosen from this list.

Source: the acrylcolor colour list issued by our supplier on 3 September 2026, with 14 colours. The sample square is an average colour measured from the manufacturer's own colour list and is therefore indicative: the authoritative identifier for an order is the RAL code beside it, not the shade you see on screen. Acrylic goes only on the outer face; acrylic on both sides cannot be ordered. We confirm the exact range currently in production in the quote, and we bring an original colour sample to the survey.
We come out, we measure, and we talk through which system is justified in your case.
Size, structure, opening type and price, item by item. We can quote several systems so that you can compare.
Removal, installation, fixings every 70 centimetres, foam sealing. The sill, the RAL tape and the removal of rubble are separate items.
Send us the sizes, or just how many openings there are. We come back within one working day and arrange a time for the survey.
