Window replacement and exterior wall

Hello everyone,

we have purchased a terraced house built in 1990 and unfortunately already need to replace the old wooden windows. Now the following questions arise: double or triple glazing? It is often said that the wall must insulate better than the window. According to the old building description, our exterior walls are made of 30 cm thick thermal insulation bricks (see photo) and built with thermal insulation mortar. But what is the U-value??? Or would you also insulate the facade before replacing the windows? Can you recommend a window manufacturer with a good price-performance ratio? Currently, we are leaning towards plastic windows. Thank you for your feedback. Best regards

Are you sure it’s the windows and not just their seals?
What makes the windows in need of replacement?
What have the neighbors done in this regard (windows, facade)?

We had a similar problem. We had a window installer come. The windows were adjusted, some new seals, a few new roller shutter belts, a new handle on the balcony door. That was all, the windows are still good and there are no more drafts. Conclusion: let a professional take a look.

In the sense of an expert, not a dealer. Dealers who smell merchandise turnover do not always remain steadfast ;-)

Hello everyone, thank you for your feedback. We already have new seals - but for some windows it no longer helps. Unfortunately.

You don't mean those self-adhesive foam strips, do you? That kind of thing not only helps little, but nothing at all, especially if the sashes are incorrectly adjusted. Take some photos, will you.
