Hello everyone,
I am currently looking for a window manufacturer for our new building. I have received an offer from the company Hilzinger, which is very attractive in terms of price.
First, about the technical specifications:
PVC profile 70mm 5-chamber, triple glazing Ug=0.7, complete window U-value 1.0, warm edge
I chose this option because I do not find it sensible to install windows at passive house level in a "normal" single-family house made of 36.5 Poroton without insulation. Overall, the window area is about 40m².
Now to my question. The offer from Hilzinger is about 10% (= €1,500) below the next offer. If I only consider the pure technical criteria, these are exactly the same windows. Where could the difference lie? Does anyone have experience with windows or doors from Hilzinger? My gut feeling tells me that something is fishy here. But I have absolutely no idea what.
I hope you can help.
Regards Martin
