Insulation around foundation by Sabine
I was wondering how to insulate the basement around the foundation. I recon, that under the foundation is out of the question, but if I insulate on the sides can I eliminate the cold bridge? Insulation on the slab of the basement is out of the question because of the height requirements. Danke 🙂

Is that existing building? If it isn’t, I see no reason why you shouldn’t plan insulation under the foundation, like on this example:

Last two examples show variations of that detail. We did a few projects with something like that, and it works.
The building is new one. But under the foundation you have to have gravel. Where do you plan to place the insulation? In between? What happens with the insulation after the whole weight of the building? Is it still effective?
Also, does anyone know after what depth in the ground thermal insulation becomes irrelevant?
In most cases it is enough to go with the insulation up until 80 – 100cm in depth. But in this case I think that Basement is heated so you have to pack everything without loosing warmth. That also Depends on your EnEv (Energy Efficiency) project. 🙂
