Thermal insulation (U-values)

Sky-Frame 2 is used everywhere where its extremely good insulation values are sufficient.

The filigree system uses insulating glass that is just 30mm thick.

Below are some U_w values for a 2-panels window (1 sliding element and 1 fixed element) calculated in accordance with
EN 10077:

W x H = 2*2.3m x 2.5m with glass

U_g=1.1 W/m²K > U_w=1.40 W/m²K
U_g=1.0 W/m²K > U_w=1.31 W/m²K
