Hello everyone,
Despite searching extensively, I haven’t been able to resolve the question about insulating our basement. Maybe you can help me?
We are building a detached house with a basement made of 36cm (14 inches) Ytong blocks. The basement includes a self-contained apartment and an office. The concrete slab has already been insulated with 10cm (4 inches) of perimeter insulation.
Both the energy consultant and the architect said that no additional insulation is necessary for the basement walls, as the Ytong blocks provide sufficient thermal insulation there.
The overall construction of the house is single-layered, so without additional insulation.
Does it make sense to insulate only the outside of the basement, or can I save the money?
Best regards!

I really can hardly imagine that Ytong® would recommend skipping perimeter insulation for a partly below-grade living basement—or rather lower ground floor (LGF) in your case. .. I see it the same way ... if there is no proper ventilation to control the indoor humidity in the basement living spaces, mold growth is basically guaranteed ..B

We are on a slope and don’t have any hydrostatic pressure .. but surface water in the "disturbed soil" can quickly turn into hydrostatic pressure ..
