Rapid US is a plastic panel suitably coated with a screen printed non-woven sheet with 50 mm pitch, which acts as a support for the PE-RT piping equipped with an appropriate hook system able to attach to the panel without the aid of clips. The panel comes in sheets folded in two to book with useful dimensions of 2x1 m, of small footprint therefore easy to transport both for the low volume involved as well as for the lightness. The system is suitable for low inertia plants occupying a total thickness of only 30 mm.
