HYBRIS is a reflective insulation product based on a honeycomb structure made of shaped polyethylene foams glued to aluminium coated polyethylene foils. Its high thermal performance is provided by a special structure composed of a large number of low emissivity cavities, protected from dust and excessive air movement. Moreover, the low emissivity external films provide additional thermal resistance, when associated with air cavities. HYBRIS significantly reduces building energy consumption while providing maximum comfort. With a core declared thermal conductivity (λD) as low as 0.033 W/mK, HYBRIS provides a thermal resistance as high as 6.20 m²K/W.
