Window offers like day and night

Seriously. There is a really big manufacturer in PL, Drutex. They do everything themselves. Located in Gdansk. And there are dozens of smaller window factories, whose names I don’t know, that, just like here in D., process the profiles of the brand manufacturers into windows. In Poland often Veka profiles, since Veka, as far as I know, also has profile factories in Poland. So it’s merely assembly of prefabricated industrial parts. With us, as said, Roton handles and hinges, Veka profiles, glass from ? Results in a window whose stickers said something about Szczecin, i.e. Stettin.

Fittings and U-value is, as far as I know, the difference with the windows. We built through GU. I think the window installer said he gets 250 euros per window including the roller shutter.

Last year, during a renovation which was very affordable due to our upcoming new construction, I bought a window from Drutex at a very low price and installed it myself. So far, I absolutely cannot find anything bad about this window - absolutely airtight.

So you would also use Drutex in new buildings? Entire hotels have been equipped with Drutex here. No problem at all.

I would use it without hesitation for my new building, however, I am now going one level up to aluminum/larch because the budget allows it. Otherwise, I would have no problem choosing these windows. Great for the price

We also installed them in our single-family home renovation. 50m² window area including front door, triple glazed with warm edge and colored foil. 9k gross + installation for Drutex, about 12k gross would have been with profiles from the German manufacturer (I just forgot the name). There is nothing to complain about the windows.

Fittings and U-value are, as far as I know, the difference with the windows.

What do you mean by difference? Between "German" and "Polish"? Drutex uses fittings from Mako – you find that with 50% of the German manufacturers too. U-values are the same everywhere; Drutex offers from passive house windows with Uw 0.7 up to standard 1.2, just like most others.

converted from our area with 50m² (including front door with Uw 1.0) we paid about €270 / m² window area with foil – including installation! Without foil it would have been about €250/m². Based on your 20 windows / 38m² that would be €9600. That fits. But I find the 35k quite a lot – our highest offer was €400/m² (all without plaster work).

BUT: The installers for us were the biggest disaster and in the end I didn’t pay everything and fixed the defects myself. Definitely pay attention to clean installation and ideally demand a RAL-compliant installation in writing, ask how it will be implemented and check!
