EFA-SST® is the classic among EFAFLEX Highspeed doors, and our most successful series.
Rising energy prices the whole world over have led EFAFLEX to completely redesign High-speed spiral doors for closing off large halls. The newly engineered design marks an improvement in the physical properties of the door blade and an optimization of its functionality. We are the world's first manufacturer to provide a series of thermally insulated EFA-THERM® insulation laths for EFA-SST®. These achieve outstanding heat insulation between 0.7 and 1.4 W/m²K depending on door size. The latest door blade
is extraordinarily robust, long-lasting, tight and sound-insulating. Depending on how much light you wish to allow in, we can incorporate as many EFA-CLEAR transparent acrylic glass laths as you like into the blade of your EFA-SST®. These are also available in double-wall design.
Should there ever be a collision, your door will still be serviceable again immediately. You can request EFA-SST® with the EFA-ACS Active Crash
System, which fully automatically repairs the door in just a few seconds. The safety mechanism ensures fully automatic, electronically monitored
retraction of the door blade after a collision. EFA-ACS eliminates expensive repairs, unnecessary downtimes and a lot of inconvenience.
