Hello! We are building a single-family bungalow with a basement! Under the living room is the double garage as the coldest room in the house! Floor on the ground floor: 11cm substructure (Styrofoam/insulation, underfloor heating), on top of that will be 6cm screed! Now to my question: does it make sense to insulate the basement ceiling again with styrodur? Otherwise, I would leave the ceiling bare (concrete)...

Hello,


In my opinion, you will not get any building permit at all if you ignore the points insulation and fire protection for the basement garage!

Kind regards

2 walls need to be insulated and a fireproof door must be installed! Obviously! But the ceiling doesn't appear anywhere! Apparently, it "does not" have to be done according to the [Energieeinsparverordnung].

He is on vacation...
Our heating installer said, however, that he wouldn't do it because then the garage would be very cold, as it would be completely outside the thermal envelope!
He says we wouldn't lose that much energy from above!

Well, if the "rest" of him is just as "professionally competent," you can expect a few surprises!
Hopefully, he has adequately considered the heat loss below the heating level in the underfloor heating.

Best regards
