The b!klimax AIR+ radiant panel consists of a special plasterboard sheet coated with a material that has a high light reflectance coefficient, capable of absorbing and reducing up to 70 per cent of the formaldehyde present in the air within the room. The surface, featuring square perforations, ensures high sound absorption performance whilst lending the panel an original and elegant appearance. The thermal insulation of the unit is provided by a 40 mm thick layer of rock wool with a density of 165 kg/m³ (rock wool fire reaction class A1), fitted with a dedicated housing for the four hydraulic circuits made from Ø6 mm PE HD-Xc pipes (pipes with an oxygen diffusion barrier in accordance with DIN 4726).
