A hinged window system that was conceived with the object of satisfying the needs of a determined market segment for an economical window system, simple but versatile with many features.

With a 70 mm frame depth and Euro Groove opening gearing, this innovation has thermal transmission from only 0,8 W/m²K in order to adapt to distinct climatic severities and material demands on energy efficiency.

Its simplicity in fitting and reduced need for labour allows for a more industrialised manufacture resulting with time and cost savings at the end.

It features a straight style in both sash and bead.

A glazing capacity of up to 65.5 mm that allows the use of energy efficient glazing and compositions with large thicknesses and affords this system excellent accoustic and thermal features.

A new Euro Groove concealed sash window design with slim profiles that are characterised by a visible surface of just 66 mm from the exterior. This maximises the glazing surface and is able to reach 85% of the total window glazing. This characteristic provides an extraordinary increase in light levels inside the dwelling.

It has been designed in such a way as to allow for the hidden sash to be maintained from the outside whilst remaining so discrete that it is impossible to distinguish from the fixed zones of the opening. This achieves perfect homogeneity in the façade’s style.

A 35 mm thermal break area coupled with the insertion of the 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 complemented with an increased level of sound insulation achieved by this system 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.
