Hello,
I am not an expert, and before insulating my roof as described below, I would like to hear some opinions.
For simplicity, I am uploading a few pictures to help with understanding.
To begin with, I can get standard kitchen rolls very cheaply.
There is old fiberglass insulation with aluminum foil between the rafters, which is only about 60mm (2.4 inches) thick. The kitchen rolls are simply pressed onto it, and the 12mm (0.5 inch) OSB boards (12mm chosen for flexibility) are screwed onto the rafters. (Rafter thickness 160mm (6.3 inches))
The visible OSB boards are sealed at the joints with Isover tape, serving as the vapor barrier.
Additionally, I want to insulate the floor, possibly using 20mm (0.8 inch) polystyrene and OSB boards.
The questions I have regarding the method shown and described in the pictures are:
- Could this lead to mold?
- Is this prohibited from a fire safety perspective? Or are there roof insulation materials with similarly flammable properties that are nonetheless commonly used?

I grabbed a few rolls and I’m just going to try it out. I also picked up some leftover Isover insulation blankets on a local classifieds site. I’ll probably do a mix and check it with a thermal imaging camera.
@hilfehilfe: I don’t have high heating costs anyway, so why be so unfriendly right away?Sorry if that came across as unfriendly! That was not my intention!
People shouldn’t have to restrain themselves but should be able to do what they want. You’ve already made your decision internally anyway. Why don’t you have high heating costs?
