- Gypsum + cardboard panel
- Steam-insulation film
- TermPIR AL, termPIR PK or termPIR WS insulation panels
- Wind-insulation film/breathable membrane or aluminium tape
The termPIR AL insulation panel is a dedicated panel for the under-rafter and inter-rafter systems. It must be sealed with self-adhesive aluminium tape. It is possible to use the termPIR WS or termPIR PK insulating panels. In this case, it is necessary to use a breathable membrane since it is impossible to use self-adhesive aluminium tape.
