External roller blinds are mainly used in renovations of existing buildings and in new constructions. They are manufactured in three types depending on the height and width of the opening and the cross-sections of the mat profiles. They are installed on the outside of the frame, leaving the original height of the opening unchanged.
It is placed externally without reducing the remaining height as is the case with the superimposed boxes
Possibility of integrated screen to avoid reduction of the remaining height in case of a separate screen
Aerodynamic design for noise reduction
