Identification

Steel frame low-energy buildings constructive system, where the achieved airtightness quality level is at least equivalent of a concrete building.

Energy losses in building are caused by both insulation and air leakage. In western Europe, the thickness has been more than tripled to increase insulation, but by contrast, the airtightness has been totally ignored and today the energy leaks due to a bad airtightness are 2 times higher than the energy losses through the insulation. A standard steel frame building shows an air permeability 6 m3/m²/h where the Sopratec III system is only 0.18 m3/m²/h. As an example a small commercial building with only 1000 m2 facade & roof surface with an air permeability of 6 m3/m²/h will leak 1,000 x 5 = 6,000 m3/h air. With an external temperature of +5°C and interior temperature of +20°C , the heating energy needed only to warm up the leaked air will be 32,4 kW, against only 1 kW with the Sopratec III.

Label Date February 2019
