Dear Insulation Experts,
I’m new here and facing my first major project:
Together with some friends, we want to buy and make habitable three old barns (so-called Rustici) in southern Switzerland. Both the shell and the roofs of these Rustici are made exclusively of gneiss slabs. These roofs are extremely durable and stable, but a few displaced stones can cause leaks. There are only a few specialized roofers left who know how to work with these roofs, but they can make them watertight again by carefully repositioning the stones. To do this, they must be able to access the roof from the inside.
This brings me to our challenge: we want to insulate the roof from the inside, but with a construction that can be relatively easily removed (in case any leaks occur).
I’m very grateful for your ideas. Here’s what I have in mind:
- Place insulation mats between the rafters, directly under the gneiss slabs, then screw OSB boards onto the rafters (also serving as vapor barriers).
- Even neater would be to attach the insulation material directly onto the OSB boards, allowing the whole construction to be removed at once. Which insulation material would you recommend for that?
What do you think of this idea? As I said, I’m not an expert and would really appreciate any advice!
Best regards

a basic question:
Would the space under the roof (attic) actually be used for living purposes?
If not, it could be designed as a cold storage room, and the ceiling of the top floor could be insulated...
Regards,
Dirk

Yes! Space is limited and the Rustici houses are not designed for our body height. One room is open towards the roof, and in the other room we would like to create a mezzanine with sleeping areas.

I am very grateful for your ideas. Perhaps a sealed inner roof could be installed, similar to a tent. Possibly made from EPDM (comparable to flat roofs). This would largely eliminate the need to monitor the cavity space.
