Hızlı spiral door EFA-SST®.

As the first manufacturer of endüstriyel kapılar worldwide, efda offers thermally separated EFA-THERM® izolasyon laths for the EFA-SST® as a standard. Depending on the door size, this allows for outstanding thermal izolasyon values of between 0.66 and 1.52 W/m² K to be achieved. Thanks to the fast opening and closing speeds of our industrial high-speed doors, little energy is lost to the outside or between two rooms.

The door leaf for the efda industrial door is extraordinarily robust, tight and sound-insulating. You can determine the required number of EFA-CLEAR® transparent laths for your EFA-SST® according to the desired incidence of light. The efda spiral does not wind the door leaf onto a shaft, but keeps it at a distance to save space. This design optimally combines highest opening speeds, durability and effectiveness.

In addition to the standard aluminium-coloured coating, we are also able to paint the door’s laths and steel parts in almost any colour from the RAL system on request. In this way, the doors can be perfectly adapted to the architecture and any façade and blend in perfectly with the appearance of your company premises.

Our high-speed sarmal kapılar have the circular round spiral, the best solution for the fastest opening and closing times, as a standard. If the space above the door is limited, you can also choose between two space-saving variants for many door types of the S series: oval spiral and low lintel.

As the world’s leading manufacturer of high-speed doors, it is our aspiration to also be pioneers in the field of güvenlik: All efda products meet the highest standards and protect both people and the goods as well as the door itself. It is not only our endüstriyel kapılar that impress with their state-of-the-art güvenlik technology, but also the associated systems: EFA-SCAN®, for example, is the world’s first laser scanner for use on doors, which is a reliable pulse generator and güvenlik system in one.
