One of the highlights of the Josko product range is the wood/aluminium Platin Blue lift-and-slide door with outstanding heat insulation values. The angular, flush glass design of the door and recessed upper guiderail make it an impressive solution. The door profiles have no glass strips and are especially narrow, while the fixed components are almost frameless. This not only ensures a maximum glass area and transparency, the standard triple glazing with Ug 0.5 W/m²K guarantees best heat insulation values of up to Uw 0.65 W/m²K.
