The system is characterised by an expanded polystyrene panel produced in compliance with UNI EN 13163 and the Minimum Environmental Criteria (CAM), moulded in closed-cell water-repellency, covered with 0.6 mm thick HIPS thermoformed film for greater resistance to deformation due to treading. Equipped with grooves on all four sides for optimal coupling, moulded upper surface with 23-mm elevations to accommodate pipes at multiple 5-cm spacings. 

The system is completed with the RDZ Tech PE-X pipe Ø 17 mm made of high-density polyethylene, cross-linked and equipped with an oxygen barrier according to DIN 4726, the hook clips, the open support bends, the manifold and the Plus perimeter frame.
