I'm going to replace the basement window in the pictures, but I'm not quite sure how to do it when it's "inmurat".
I've replaced a dozen windows in wooden walls but never in a concrete wall.
The wall consists of 25 cm concrete blocks. Nothing else.
How is it usually with windows in a concrete wall? Are there shims under the frame as usual, and you insulate as usual? And then plaster on the outside and inside, against the frame?
Or have they built in wooden studs that then attach the window to?
Or how might it be done?
The opening has some unusual dimensions, 141x67.5 cm. If I'm going to fit a 14x7 window, I have to remove the plaster, but maybe I should do that anyway to get the window out?
Or should I saw off the frame and break it out, so the plaster remains intact? But then I have to put in studs in the "spår" and buy a smaller window.

Can anyone advise me?
Grateful for answers.
 
  • Old basement window in a concrete wall likely set in 25 cm concrete hollow blocks, surrounded by plaster, with a hose pipe attached nearby.
  • Close-up of a concrete wall with a window frame corner, showing signs of wear and cracking around the edges.
  • Close-up of the corner of a basement window frame embedded in a concrete wall, showing cracks and damaged surrounding plaster.
  • Close-up of a weathered window frame set in a concrete wall, showing cracked paint and some visible gaps and edges.
Saw the frame and break it "in" to damage as little plaster as possible. The module is 20-25mm smaller in height and width. On the outside, plates (L-shaped) are usually installed during replacement, and on the inside, sealing, plastering, or lining is done.
Preferably mounted with Adjufix with the accompanying attachment on the sleeve if there's nothing sensible to pull on! Good luck :)

Best regards, fremax
