ᐅ Issues with the Edge Insulation Strip!

Hello everyone,

I will start installing the screed insulation in the next few days. I have the following problem. My perimeter insulation strip is 15cm (6 inches) wide. The floor construction has a height of 15cm (6 inches) and 17cm (7 inches).

How should I install the perimeter insulation strip? Can I lay the first layer of insulation/impact sound insulation first, then install the perimeter strip, and afterward the fixing panels, or does the perimeter insulation need to reach all the way down to the raw concrete floor?

Thanks for your help.

I am not a professional, but in our case, the edge insulation strip was glued onto the fastening board.

I also don’t see the point in extending the insulation strip all the way to the unfinished subfloor since it only serves to decouple the screed from the masonry.

It doesn’t have to be installed on the unfinished subfloor. We did it this way as well: first layer of insulation, then edge insulation strips, followed by impact sound insulation.

Hello questioner.
The answer from "readytorumble" might have been given off the cuff, but it is correct!
According to the standard, the edge strip (screed edge strip) must, in the case of single-layer insulation, extend down to the load-bearing substrate (note this refers to the concrete slab). For multi-layer insulation (note this is the situation we have reduced to the facts, and although simplified, it is technically accurate), the edge strip must be installed before applying the impact sound insulation layer and secured against unintended displacement along the wall surface.
