Hello,
The granting of an energy and roof renovation bonus is subject in Wallonia to a thermal resistance requirement of
insulation placed> = 4,5 so I deduced that this was the minimum requirement. NO ??
Addressing the problem of infiltration is indeed the priority, a single moderate infiltration for 1 year.
Never understood where it came from (temperature is average, rain and wind fairly dense but there were worse without consequences these times).
To calculate the dew point, as I thought, you must first be equipped to measure the% humidity inside and outside ...
If you still have a little time to devote to me, I will come back to point 3 ie the insulation of the attic attic (office which will be heated by a radiator that I have already connected but the boiler is not yet in service) which is also a priority for me since I sometimes sit there for hours.
Thank you for your contribution which confirms my reasoning even if the decisions are still pending.
