The frameless sliding windows comprise insulating glass units with perimeter aluminum or glass-ﬁbre-reinforced plastic (GRP) sections. Mounted in aluminum frames that are ﬁtted ﬂush with ﬂoor and ceiling, the sliding units offer minimum rolling resistance when operated. The system drainage for the ﬂush assembly is via a recessed channel or is installed below the raised outdoor ﬂoor covering. Sky-Frame Original is suitable for all climates and available for the systems Classic, Arc and Slope.
The 12 mm thick, single-glazed Sky-Frame 1 units are suitable for applications without thermal insulation requirements. The system also incorporates special sliding seals that offer a high level of sound control.
The excellent sound and thermal control standards met by the Sky-Frame 2 technology have made it the most popular Sky-Frame solution. The slim (only 30 mm thick) double-glazed insulating glass assembly has proved an outstanding performer in a wide range of climate zones.
The Sky-Frame 3 system with its 54 mm thick insulating glass units meets the highest standards. The triple-glazed elements offer extra stability and even greater resistance to wind loads.
