Good evening,
it's me again...
But I’m really impressed with the help here, no matter the topic.
One more question, this time about insulation between rafters:
- Rafters are 220mm (9 inches) thick
- Can / should / must I fill the entire rafter thickness?
- So, do I use 220mm (9 inches) insulation with a thermal conductivity of 0.035 W/(m·K)
- Or 200mm (8 inches) insulation with 0.032 W/(m·K) and leave 20mm (1 inch) of air space?
Thanks,
Regards and stay healthy!

So, practically speaking: the roof is covered. We are doing the insulation between the rafters ourselves.
From the inside:
- drywall
- counter battens / laths
- vapor retarder
- insulation
That’s the end of our work; the rest is already “on the roof,” correct?
