High-Speed Insulated Spiral Door

A better heat insulation then ever before is from now on guaranteed by the 60 mm thick EFA-THERM® insulation laths! The laths are thermally separated as a standard. Especially developed details provide excellent vertical and horizontal sealing of the EFA-SST® ISO-60. The vertical insulation towards the frame is carried out by thermally separated aluminium profiles with nearly wear-free sealings. The horizontal space between wall and door leaf is closed by an active lintel sealing made of aluminium. For being used even in conditions of high temperature differences and/or high humidity, both sealings can optionally be equipped with heating tapes.
