Kaba thermally insulated cylinder Cold outside - dry inside

Secure access in any weather  
The thermally insulated cylinder (TIC) is thermally insulated by separating the outside and inside of the cylinder housing with a plastic middle piece. This prevents coldness and moisture from being transfered from the outside to the inside. The TIC cylinder is suitable for all applications in which water from condensation or even the formation of ice on the inside of the cylinder can be expected.  In addition, this cylinder is sealed off against driving rain. At the same time, the sheet rain seal increases tightness against drafts.

  • Protection against condensation water on the inside also under extremely cold outside temperatures
  • On the outside and higher protection against drafts (˝blower door˝ Test)
  • Ideal for passive houses and outside arcade doors
  • Available with thumbturn knob and asymmetrical cam
  • Foam rubber insulation for sealling the door lock
