Standard EPS 400 is used as support elements for pipes in dry underfloor heating systems. The physical properties of EPS 400 polystyrene provide optimal thermal and acoustic insulation of the system. Veneer in the form of aluminum foil ensures optimal heat distribution on the surface of the plate. Made from high density recyclable expanded polystyrene (EPS) and uses 16mm pipe with 4 channels spaced 150mm apart for maximum efficiency.
