Problems with the edge insulation strip!

Hello everyone,

I will start with the screed insulation in the next few days. I have the following problem. My edge insulation strip has a width of 15cm. My floor structure has a height of 15cm and 17cm.

How do I install the edge insulation strip now? Can I first lay the first layer of insulation/impact sound insulation, then attach the edge insulation strip, and after that the tacker plates, or does the insulation strip have to reach down to the raw concrete floor??

Thanks for the help

I am not an expert, however, in our case the edge insulation strip was glued onto the stapler plate. I also see no point in laying the insulation strip down to the raw floor, after all it only serves to decouple the screed from the masonry.

He does not have to put it on the bare floor. We did it this way as well: first layer of insulation, then edge insulation strips, and then impact sound insulation.

Hello questioner. The answer from "readytorumble" may have come from the gut, but it is correct! The edge strip (screed setting strip) must – according to the standard – rest on the load-bearing substrate (Anm. that is the concrete slab) for single-layer insulation layers. For multi-layer insulation layers (Anm. this is the situation as we have reduced it to the facts, but can see it as technically correct) the edge strip must be installed before the installation of the impact sound insulation layer and secured against unintended displacement on the wall surface. --------------------------- Regards: KlaRa
