Hi everyone,
In another thread, I asked about installing a mechanical ventilation system with heat recovery. It looks like the planned floor construction for my project may not be ideal for installing such a system.
The current plan is:
50 mm (2 inches) insulation
30 mm (1.2 inches) staple board
70 mm (2.8 inches) cement screed
10 mm (0.4 inches) tile/parquet flooring
------
Total 160 mm (6.3 inches)
If it were changed to:
70 mm (2.8 inches) insulation
20 mm (0.8 inches) staple board
50 mm (2 inches) screed
10 mm (0.4 inches) tile/parquet flooring
------
Total 160 mm (6.3 inches)
everything would be fine.
Now my question:
What is the exact purpose of the staple board? Is it just to hold the pipes in place until the screed is poured? For that, wouldn’t about 10 mm (0.4 inches) be sufficient?
Why are there 20 mm (0.8 inches) and 30 mm (1.2 inches) staple boards available?
What are the advantages and disadvantages between 20 mm and 30 mm thickness?
Thanks and best regards,
Andreas

In practice, it can help to place some weight on the panels here and there during the pipe layout. The clamp itself does not hold in the polystyrene (or whatever material the insulation board is) but in the membrane due to the "barbs."
Therefore, whether you choose 70 / 20 or 60 / 30 probably doesn’t matter much. I would go for the more affordable option or whichever fits your ventilation space for sure.

Hello,
The different thicknesses of the "fastening plate" are used to achieve various build-up heights. The surface is not waterproof. With careful installation, including using the edge insulation strip, it is possible to lay liquid screeds. However, in most cases, screeds are installed with a damp consistency.
There are also several differences among the commonly used pipes. Composite pipes are very easy to install since their bent shape is maintained. PE-RT pipes and especially PE-XC pipes tend to revert to their original shape. It is therefore advisable to use more clamps in the curved sections.

Of course, the panels won’t be 100% waterproof once you puncture them. But at least they hold up against the flowing screed, which is very, very fluid...
