Doors in cold storage rooms must withstand enormous stresses. Top quality and perfect workmanship are prerequisites if all components are to defy cold and moisture. EFA-SST®-ISO-60 is the ideal tight sealing door if effective insulation is demanded of heavily frequented openings, such as those to cold storage rooms.
The EFA-SST®-ISO-60 combines two EFAFLEX door technologies into an innovative solution: the multiply patented spirals and highly insulating laths. Elaborate seals additionally prevent air and heat exchange. An excellently insulated door such as the EFA-SST®-ISO-60, which opens and closes very rapidly, helps you substantially lower your costs and creates constant climatic conditions at your establishment.
Now, 60 millimetre thick EFA-THERM® insulation laths guarantee better heat insulation than ever before! These laths come thermally separated as a standard. Especially developed details produce the excellent vertical and horizontal sealing of the EFA-SST®-ISO-60. The vertical insulation against the door frame is made with thermally separated aluminium profiles with low-wear seals (see photo above). An active aluminium head seal seals the horizontal space between the structural connection and the door blade. For use in large temperature differences and / or high air humidity, both seals can be optionally equipped with heating strips.
