Offering the timeless appeal of the sliding window assembly, Classic was the first ever Sky-Frame system.

The sliding windows comprise insulating glass units with perimeter aluminium or glass-fibre-reinforced plastic (GRP) sections. The aluminium frames are fitted flush with both floor and ceiling, with system drainage in a recessed channel below the raised outdoor floor covering. The sliding units offer minimal rolling resistance for ease of operation.
