Future-proof stone width?

Good morning dear forum,

regarding our house planning, a question has come up:

Every year the guidelines for houses and their insulation (new construction & existing buildings) are tightened. If I build now - assuming 36 masonry with a thermal conductivity of 0.09 - will I have to retrofit/insulate in the future?

If that is the case, are there wall values (thickness/conductivity) where subsequent insulation can be excluded?

Thanks and best regards
Peter

Hello,

...Every year again the guidelines for houses and their insulation (new construction & existing buildings) are tightened.

This usually concerns new construction.

...If I build now - assuming 36 masonry with a thermal conductivity of 0.09 - do I have to retrofit/insulate in the future?

That is no longer a solid (monolithic) stone, but rather a cookie monster ;-)

best regards

I would spontaneously guess aerated concrete (Ytong) ^^

If I build now - assuming 36 masonry with a thermal conductivity of 0.09 - will I have to retrofit/insulate in the future?

Possibly if the facade needs to be refurbished in 20 years... otherwise, it will probably not come to that...

If that is the case, are there wall values (thickness/conductivity) where subsequent insulation can be ruled out?

About 80-90 cm of Ytong or more should be enough at first to be on the safe side!

Hi, I interpret the first two answers to mean that if anything, corrections would have to be made at the earliest during a façade renovation. Otherwise, the two responders seem to be opponents of the monolithic construction method ("Krümelmonster", "80-90cm Ytongg"), right?

No, you have to differentiate here. Self-build or company work? In the latter case, it would always make sense to separate load-bearing (structural engineering), soundproofing, and insulation, i.e., each should be handled by the respective specialist. Anything else would be a compromise. In self-build, it often looks a bit different, as other aspects also come into play.
