Staple plate 20 or 30 mm?

The plates may lift slightly due to the pressurized pipe, but that is not a big deal. Thicker plates might withstand this better, but that is just a guess. Practically, it is useful to weigh down the plates here and there during the design of the pipes. The staple itself does not hold in the Styrofoam (or whatever it is) of the stapler plate but in the foil through the "barbs."

Therefore, 70 / 20 or 60 / 30 probably does not matter much; I would get the cheaper one or the one where you can definitely fit your ventilation space-wise...

Hello

The different thicknesses of the "Tackerplatte" are used to achieve different installation heights. The surface is not waterproof. Cleanly processed, also with the edge insulation strip, processing of flow screeds is possible. In most cases, however, screeds are installed earth-moist.
There are also various differences with the commonly used pipes.
Composite pipes are very easy to lay as the bent shape is retained.
PE RT pipes and especially PE XC pipes always try to return to their original shape. Here, using a few more clips in the bend area is advisable.

Right, I had forgotten that... In the bends, depending on how tight they are, you can put a clip every 10cm or even closer... If anyone still needs clips, I should have a few hundred left that can be sold cheaply... Of course, the panels are not 100% waterproof if you poke holes in them. But at least they withstand the flowing screed, and that is very, very fluid...
