Hello! Thank you very much for your interest in my issue 🙂
First of all: I am not a professional.
I want to insulate my screed floor (160 m² (1720 sq ft)) with insulation panels on a (basically) level concrete slab. The panels can be installed as a floating floor.
- Do I need a vapor barrier? One supplier (Anderhalden AG in OW) advised against it, while others recommend using one.
- One room of 25 m² (269 sq ft) is about 2 cm (0.8 inches) higher than the rest of the area. How should I handle this? Do I need to add a leveling layer to the rest of the floor, or is there some kind of bridging solution?
- Are there any important points I might have overlooked?
Thank you very much for your advice!
Best regards,
Phil

Whether you need to install a vapor barrier or not should be clarified with the manufacturer of the insulation panels; for example, new cement screed can release moisture (as vapor) for quite a long time. Although the amounts are small, they could still lead to defects.
If you want a uniformly level floor, a base layer must be applied; there are base layers with a minimum thickness requirement that should be considered when choosing the product. Bitumen-coated wood fiber and granulate base layers, for example, can be applied from 1cm (0.4 inches) thickness.
All technical aspects to consider during installation can be found in the product’s technical datasheet and the manufacturer’s processing guidelines – it is important to read and follow these carefully; datasheets are usually available on the manufacturer’s website.

The question was about insulating a floor; Thermo-hemp is not suitable for this because it is not sufficiently compression-resistant.
