Aluminium with enhanced thermal insulation, which can be made in exceptionally large sizes. It belongs where the design calls for a large glazed area and the view is the point.

A premium family house, where large windows and balcony doors are in the plan.

The data in the table are the manufacturer's official product figures. The Uw value refers to the best version available; your own window is also affected by size, glazing and glazing bars, so we write the actual value into the quote.
Aluminium is stronger, so it can carry a large sash on a narrower frame. More glass and more light fit into the same opening.
A powder-coated finish that does not fade or warp. The colour range is practically the whole RAL scale.
Aluminium costs more than PVC. If value for money is the main consideration, the Kömmerling PVC line is the better choice, and we will say so.
We do not publish a price list, because we manufacture to measure and a price written for a standard size would be misleading anyway.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 have them made to measure, so the size of the opening and the quantity are the first factors. The advantage of aluminium is precisely that large structures can be built from it, but the size shows up in the price too.
Triple, safety and acoustic glass carry a surcharge, as does RC2 burglary-resistant hardware. You see each of them on a separate line in the quote.
The powder-coated finish can be ordered in practically the whole RAL range, with a surcharge for special colours. The strip-out and the installation are included, the sill is a separate item. Scaffolding is rarely needed, only where the height calls for it.
We also quote the same opening in PVC, so that you see the difference in forints rather than deciding on a hunch. We give a 5-year guarantee on the installation. Request a quote →
If this line seems too much, or not enough: Basic aluminium · Exclusive aluminium. If you want to see timber on the inside, that is the timber-aluminium window. If a metal look on the facade is the aim but price matters, then the aluminium-clad PVC window is the middle way.
In the same visit as the window replacement we also fit shading, in one call-out.
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.
