What function will the protective radlies perform
Rolls are one of those few relatively young inventions, thanks to which you understand that construction and window technologies are developing in the right direction. Indeed, it is difficult to imagine such a device or device that will solve as many global and useful tasks as rollers.
The main function of the rolllet (or roller shutters) is the protection of motionless property from extraneous interventions, or, in other words, protection against hacking. And in this regard, they perfectly replace the once -popular forged metal lattices, as well as bulky and uncomfortable shutters. The advantage of the rolllet over traditional protective devices is that they easily and very quickly open from the inside of the room, without cluttering the evacuation paths, which is very important when the fire occurs.
