This Warmup VLo Nexxa-12 Castellated System Panel is a self-adhesive board that holds 12mm PERT pipe in place when installing underfloor heating. The board measures 650 x 1050mm and is ideal for low-profile or retrofit projects. Made from recyclable polystyrene, the panels are easy to cut and fit around obstacles. Once the pipe is laid, a 22mm levelling compound is applied directly on top, with no overboarding needed.
