Hello everyone,
this is my first post here and I hope someone can help me a little with my questions – I am thankful for any answer and help!
My girlfriend and I are the builders of a single-family house and we are currently installing the insulation in the intermediate ceiling, garage, and attic ourselves (in consultation with a drywall specialist). We are a bit worried that we might not be doing everything right or have done it correctly. I hope you can help us!
The questions are:
- In consultation with the architect and structural engineer, we did not fill in the rafters, but pushed the insulation all the way to the outside (see pictures)
1. Is this correct?
2. Should the circled gap (approx. 5-8 cm deep up to the rafter) also contain insulation?
3. Does the board from the carpenter go directly on the insulation, or should there be a vapor barrier on it?
- We plan to insulate both the intermediate ceiling and the attic. The attic will not be converted. Is this correct?
- The rafter height of the intermediate ceiling is 200 mm, the attic 240 mm. For the intermediate ceiling, we used 180 mm of insulation to allow for an air gap; for the attic, we intend to use 240 mm because the diffusion-open foil should also provide ventilation without an air gap. Is that correct?
- Some insulation mats in the intermediate ceiling sag a bit (otherwise they were not held properly and would always fall out). Is this correct? (See pictures)
- We have stuffed existing gaps/holes with leftover material – is that correct?
- Once all insulation and vapor barriers are installed and windows/doors are fitted, we plan to rent a thermal imaging camera to detect thermal bridges.
1. Does this make sense?
2. If we don’t find any thermal bridges, can I be sure that everything was done correctly? I am particularly concerned about cavities between outside and inside and the possible resulting mold.
- Are there any other things we should consider?
Best regards and many thanks in advance
