Windows – The basic system of the KELLER CLASSIC side elements
forms the AWS 70 HI series of the quality brand SCHÜCO witha construction depth of the frame profiles of 70 mm and leaf profiles of 80 mm.
The thermal insulation comprises a new composite system for aluminium half profiles using triple-chamber insulating bars with additional insulation and special seals in the rebate regions.
This leads to very low heat loss which reduces heating energy consumption and so also lowers emissions.
