Hello everyone,
we insulated the sloping ceiling (24 cm thickness) and the floor ceiling (12 cm thickness) ourselves with rock wool. We also installed the vapor barrier ourselves.
Now the insulation in the floor ceiling is open upwards, i.e. towards the walkable roof truss, at the sides. There is a gap of about 5 cm.
The roof truss is currently only used as a storage area and the floor is made of ESP boards (with tongue and groove).
See also the pictures. The vapor barrier of the sloping ceiling was connected to the main purlins of the roof truss. Foil = Neovap 20 from Dörken (Sd value of about 20 m)
Now the question: Can it stay like this or do we need to close the gap with foil?
We insulated the whole thing in April, after the moisture from the interior plaster and screed was already out of the house. The insulation is bone dry.
According to the Energy Saving Ordinance, we would have only had to insulate the sloping ceiling, by the way. We then added the floor ceiling as additional insulation (cold and heat protection) as well as soundproofing.
Thank you in advance.
Best regards
