SUNFLEX: Folding Door Systems

Extend your attitude towards life

The all-rounder among the glass systems: Folding door systems from SUNFLEX. The connected panels make them particularly easy to handle. In addition, they stand out due to the large range of variants available – from the non-insulated system for interior applications to the highly thermally insulated system as a wall closure in passive energy houses. Our folding door systems are thus especially suitable for conservatories or as terrace doors in your home. Thanks to the low profile depth, you do not have to compromise on either barrier freedom or energy efficiency, even with maximum thermal insulation.
