Alu HD Diffusion

Alu HD Diffusion

Flat insulating panel in sintered expanded polystyrene (EPS), available in white and with improved thermal conductivity (graphite), to which an aluminum alloy sheet is coupled with a printed on installation grid useful for laying the piping.

The aluminum alloy sheet with a thickness of 250 µm guarantees rapid heat diffusion and gives the system a robustness that can adequately resist the stresses due to the trampling of operators and the humidity of the screed during construction phases; it also acts as a vapor barrier in the operating phase of the radiant system.

The foil is equipped with two self-adhesive edges to ensure the overlap between adjacent panels in such a way as to allow adequate overlapping and a solid coupling, ensuring an optimal seal during the installation of the panels and the casting of the screed.
