This system requires a smooth pose more specialized than the ashlar, but has the advantage of better compacting the screed around the pipe, allowing a better yield than the ashlar. The correct execution is guaranteed by modulbarre to step 5, but still remains more than the rough ashlar.
Suitable for capannoncini, workshops or stores no larger than 1000 square meters.
The module is provided for the laying step 20 everywhere.
The tube diameter is 20×2 choice PE Xa or PE-RT (both with EVOH oxygen barrier).
The distribution can be predicted by the collector or integrated group built a fixed point or climate (material choice polyamide or brass).
