Insulate basement exterior wall due to 10,000 houses program

Ok, then clear. Thanks to you!

The question is still whether there is an external insulation for the basement with a WLG value of 0.32 ?? Does anyone know something about that?

Oh yes: 2 seconds on Google would have helped you a long time ago ;)

I have googled as well. What I’m not clear about is which of the insulations can also be used underground and which are external insulations? Perimeter insulation is also the insulation that is applied under the floor slab, right? That’s why I asked here if someone can say, this is exactly the product you need. Ideally, my house construction company would tell me the solution. But they want to install internal insulation for 5000 euros and that’s it.

Perimeter insulation is always the insulation against the ground. Whether it is also allowed under the slab is shown by the manufacturer's approvals regarding compressive strength. What is designated as perimeter insulation may definitely be installed up to a depth of 3m.

Thanks for the info. Then I probably have to clarify with the energy consultant what value he needs so that we can save ourselves the interior insulation.
