Hello,
I have been reading this wonderful forum for some time now. I finally managed to register and would like to start with a question.
Our roofer recommended installing additional cavity insulation. It should be 160 mm (6 inches) thick, and his suggestion is to use mineral wool combined with wood fiberboard panels for this extra insulation. He mentioned that the attic already has excellent thermal insulation. Our architect was also enthusiastic about this.
However, this will cost extra, and a rough estimate puts it at an additional 3,500 Swiss francs.
At the hardware store, an employee said that the mineral wool alone provides good insulation. Now I am a bit uncertain and would like to ask for your opinions here.
What experiences have you had, and is it worthwhile to use mineral wool as insulation?
Do the wood fiberboard panels offer any additional benefits?
These panels are supposed to maintain their functions for several decades.
Thank you in advance.
Best regards

Hi everyone,
An interesting discussion. One question upfront: How thick are the rafters? Insulation with mineral wool is effective. In winter, it keeps the heat inside the building, and in summer, it serves as thermal protection. If windows are installed, the comment about shutters is valid. If the attic is to be converted into a living space, covering the rafters with drywall is a good idea. If desired, a counter battens system with an additional layer of insulation can be added to further improve its effectiveness.
