The industrial system with SUPPORT BARS Ø 20/25 is ideal for underfloor heating of warehouses. The system consists of a PVC bar with U profile to house the pipe Ø 20/25, distance 50 or 100 mm, equipped with a lower adhesive band for fixing on the polyethylene sheet with or without thermal insulation. Special clips allow the support bar to be anchored to the thermal insulation layer and plastic dowels ensure that the panels do not rise during the laying of the pipe.
