Hello, I am currently gathering quotes for the installation of a front door, garage door, garage gates, and especially windows.
Company A offers Schüco windows and Graute front doors (also Schüco or Hörmann if desired).
Companies B and C sell Kömmerling front doors and windows.

Are there any concerns regarding any of these manufacturers, or are they all of equal quality when comparing identical U-values?

I have no experience at all with which products are good. All the brochures read very well, especially the passive house versions.

Best regards

Hello Becker84,
no, manufacturers are not necessarily of equal quality just because the U-values are the same. Nobody can really judge that since many important details are missing. For example:
- Who is the manufacturer (Company A, B, C)?
- Which window system from Schüco, Kömmerling? The companies you mentioned are profile manufacturers. They only supply the plastic profiles to the window manufacturers.
- Who installs the units?
- Color, size, construction type of the windows?
- Glass? ...

Regards, Peter

Oh, I see, good to know... No one told me about that.
I will post it here as soon as I find out.
