ᐅ Removable Roof Insulation – Ideas

Dear insulation experts,

I am new here and need some expert advice:

Together with a few friends, I want to buy and renovate three old farm buildings (so-called Rustici) in Ticino. Both the shell and the roofs of these Rustici are made entirely of gneiss slabs. These roofs are extremely durable and stable, but individual displaced stones can cause leaks. There are only a few specialized roofers left who are familiar with this type of roof, and they can fix leaks by carefully repositioning the stones. However, to do this, they need to be able to access the roof from the inside.

This leads to our challenge: We want to insulate the roof from the inside, but with a construction that can be relatively easily removed again (in case a leak occurs).

I would be very grateful for your ideas. Here is what I have considered:

- Placing insulation mats between the rafters, directly under the gneiss slabs, then screwing OSB boards onto the rafters (which could also act as vapor barriers).

- An even neater solution would be to install insulation directly on the OSB boards, so the entire assembly could be removed at once. Which insulation material would you recommend for this?

What do you think of this idea? I am not an expert and would really appreciate any advice!

Kind regards

That is quite an ambitious project, this renovation. This rigid PUR foam is a good option for making the roof watertight. The fact that it is waterproof is also a positive aspect. Additionally, this insulation material has a long service life.

Thanks again for your input. I didn’t know that this rigid PUR foam has such good properties. I also want to insulate our roof from the inside and will use this rigid PUR foam for that.
