Heat-insulating sliding door

SIR40 Resin-made heat-insulating sliding door for low-temperature cleanrooms

For the exit and entrance of low-temperature working rooms at about +15C, doors are required not to cause condensation at this condition. The greatest features of SIR40 with all-resin frame materials are its smart-looking appearance and light open/close movement, while maintaining high thermal insulation performance. Three types of open/close mechanisms are available: manual, self-closing, and automatic.

  • Smart-looking appearance while maintaining thermal insulation property.
  • Very light weight due to the combination of resin frame and styrene foam inside the door.
  • Some chemicals that cannot be supported by metallic sliding doors can be supported.
  • Various options are available, such as resin-made FIX window that is exclusively for double glass.
  • Fully custom-fabricated in the unit of one millimeter.
