Sound systems - Import export

70 COR aluminium windows are characterised by thinner profiles, resulting in a section of only 66 mm visible from the outside and maximising the glazing area. This feature allows an extraordinary gain of light in interior rooms. And this is complemented by maximised thermal efficiency, thanks to the 35 mm thermal barrier and the polyolefin foam insert in the frame and sash that allows for heat transfer coefficients of up to 1.0 W/m²K. COR 70 aluminium windows have a high degree of sound insulation, which this system achieves in particular thanks to the possibility of installing glass up to 40 mm thick
