ᐅ Ground-level terrace exit with exterior wall insulation

Hello everyone,

We are currently insulating our facade with 16cm (6.3 inches) EPS. The insulation will be extended down to the level of the basement windows, so it will also run underneath the patio doors. The basement itself is not heated. Now we are wondering what the best solution is for the patio exits. According to our energy consultant, we are not allowed to omit insulation under the doors. Our builder says that we cannot lay patio slabs on top of the insulation because the insulation boards cannot support the weight.

One solution we found would be a stepped exit, similar to a windowsill. However, this would result in a step. Ideally, everything would be on the same level.

Does anyone have any ideas or have faced the same problem?

Here is a photo showing one of the patio doors at the bottom. The entire facade will be insulated. The terrace area will be built up with fill material.

We basically have window sills

Cool, thanks a lot! I just found something similar online, but yours look nicer. Do you happen to know where they are from or what they are called?

What about the windowsills? No, they were provided by the general contractor.

Ok, too bad. I sent our general contractor a few links; maybe they will find something. The energy consultant also wanted to give it some thought.

The calculation lists Granit Delia Light. When I search for it on Google, the color doesn’t match. I don’t have the sample selection on hand at the moment.
