ISO – SL
The slightly curved form of the ALU profile secures smooth operation of the door. The special, soft PVC reinforcement on the inside of the lamella ensures that sound is absorbed even by maximum opening speed (max. = 1,7 m/sec).
The inner reinforcement is interrupted by a thermal bridge placed between the inner and outter side of the roller, due to which the thermal permeability is reduced.
This door is a synonym for high speed, quiet performance and great thermal insulation.
