Hello everyone,
I need some opinions from the experts regarding the repair of the inner window reveals. But first, a little background:
Two years ago, we moved into a mid-terrace house built in 1969 (and have since renovated just about everything). The windows date from the late 80s and are okay, except for the roof (completely newly insulated and covered), so we have not carried out any further insulation measures. The roller shutter boxes can be accessed from inside; each has a simple plywood board attached inside at the bottom of the roller shutter box (slid in with a rail, see photos). These are neither insulated nor particularly airtight.
I have since replaced some of these plywood panels with (insulated) plastic covers. I removed the rails of the old covers, plastered everything over, and now screw the new covers in from below.
However, at some windows, I have the problem that there is a gap—more or less large depending on the room—between the inner reveal and the window frame. At the worst spots, you can even see the construction foam from the window installation. (At the time of viewing, there was nicely wallpapered over all of this...) There is sometimes quite a strong draft, which may be good against mold formation, but regarding draughts and heating costs, I would like to reduce this "forced ventilation" somewhat. And before I replace the roller shutter cover there, I would first have to finish repairing the reveal at these windows.
After some internet research, my idea would be: plaster over the existing holes, then install a suitable calcium silicate board (reveal board) on each left and right side of the window reveal, and finally plaster/paint it. However, someone at the building supply store told me I should rather use suitable polystyrene boards for this. I tend to think that in terms of moisture regulation and mold prevention, the calcium silicate boards would be more appropriate? They are sometimes also available in fairly narrow versions, as I don’t necessarily want to knock off additional plaster everywhere...
What is the experts’ opinion on this? I would simply like to make it a bit more airtight but so that nothing rots later, etc.
Thanks in advance for your tips!
Regards,
Stephan
