1. Increased sash dimensions

The system allows to assemble the sash up to 3300 mm in height and up to 3200 mm in width (it is recommended to use reinforcing elements while working with sashes of huge dimensions).

2. High thermal insulation level (Uf ≤ 1,3 W/m²K).

The usage of wide polyamide thermal bridges as well as the possibility of 50 mm triple glazing installation allows to perform better values of thermotechnics. The frame U-value comes up to 1,3 W/m²K.

3. Anti Bi-Metal polyamide thermal bridge

The usage of 32 mm «Anti Bi-Metal» polyamide thermal bridges in the sash profiles allows to compensate the changes caused by the temperature deviations between the inner and outer sides of the combined profiles.

4. Compatibility with ALT W72 series

The system retains the seam space geometry for infill unit equal to W72 series – the possible infill thickness is from 26 to 50 mm. The mounting depth of the SL160 sash profiles also coincides with the W72 profiles, so when using the SL160 in conjunction with the standard "warm" ALT series, the style remains unified and the perception of the external and internal appearance of the objects is ensured.
