Hello,
in our house from 1964, the roof is to be insulated and re-roofed. Currently, there are pumice stones between the rafters in the upper floor area, which, according to the energy consultant, should be removed for summer heat protection and replaced with insulation between the rafters. However, when removing the stones from the outside, it is very likely (according to 2 roofers, the energy consultant, and our own assessment) that the interior plaster on the sloped ceilings in the upper floor will be damaged or fall off (reed mats as plaster carrier in between).
Now we have the following options:
1. Remove the stones directly from the inside ourselves, install panels on the slopes (exact execution would need to be planned again if this option is chosen).
+ Advantage: Being able to renovate the rooms inside independently of the roofer without the "fear" that something will fall off again and create dust and dirt.
- Disadvantage: Additional effort, as the slopes otherwise would only need to be re-wallpapered.
2. Wait until the roofer removes the stones from the outside (probably in summer) and then see to what extent the slopes need to be replastered or covered with panels.
+ Advantage: Currently less effort, no possibly "unnecessary" removal of plaster.
- Disadvantage: Uncertainty and no "completion" of the upper floor before moving in in May.
3. Leave the stones in place completely, insulate on top of the stones (recommendation of the roofer, but the energy consultant still needs to calculate whether this is sufficient for summer heat protection and recommends removing the stones).
+ Advantage: Least effort.
- Disadvantage: Possibly heat stress due to the stones heating up in summer.
I would be interested in opinions and experiences, especially regarding warming pumice stones in summer (roof faces east/west). Our bed would also be directly under a slope, so heat radiation in summer would probably be quite uncomfortable.
Thank you very much!
