Worldwide increasing energy prices have prompted EFAFLEX to design completely new high-speed spiral doors as hall closure. The technically new design constitutes an improvement of the physical characteristics of the door leaf as well as an optimization of the functionality.

As the first manufacturer worldwide, we will now offer thermally separated EFA-THERM® insulation laths for the EFA-SST as a standard. Thus, depending on the size of the door, excellent heat insulation of between 0.66 and 1.52 W/m2K can be achieved. The new door leaf is exceptionally robust, long-lived, tight, and sound insulating. Depending on the desired light entry, we include as many EFA-CLEAR transparent laths of acrylic glass into the door as you wish.
