Hello,
I have been reading in this wonderful forum for some time. Now I have finally managed to register here and I am starting right away with a question.
Our roofer recommended installing an additional intermediate insulation. It should be 160 mm thick and his suggestion is to install this additional insulation with mineral wool and wood fiber boards. He said there is already wonderful thermal insulation in the attic. Our architect was also enthusiastic.
But that costs extra money and with a rough calculation, we are at an additional 3,500 francs.
At the hardware store, an employee said that the mineral wool alone already insulates well. Now I am a bit uncertain and therefore ask here.
What experiences have you had and is it worthwhile to use mineral wool as insulation?
Do the wood fiber boards also provide additional benefits?
These boards are supposed to fulfill their functions for several decades.
Thank you in advance.
Best regards
