Cor-70 Hidden Sash System with Thermal Break
A new Euro-Groove concealed sash window design with slim profiles that are characterized by a seen surface of only 66 mm from the exterior that maximises the glazing surface and is able to reach 85% of the total window glazing. This characteristic provides an extraordinary increase in luminosity in the inside of the dwelling.

Its design allows for the hidden sash to be maintained from the outside in such a way that it is impossible to distinguish from the fixed zones that the opening has and therefore achieving perfect homogeneity in the façade’s style.
 
A 35 mm thermally broken area and the insertion of polyolefin sponge in the frame and sash allows it to reach values of up to 1,0 W/m²K of transmission in the space and therefore maximising its energy efficiency. These high thermal performances are completed with an increased level of sound insulation that this system achieves thanks to the possibility of installing glazing units of up to 40 mm in thickness.
 
The classifications achieved in the AEV tests go to prove that the system has excellent water tightness, air permeability and wind resistance values in order to obtain increased protection against the most unfavourable weather conditions.
