External roller shutters are modern window covers that protect interiors from overheating in summer and heat loss in winter, and reduce noise levels. They are excellent protection against wind, rain, sun, snow and other atmospheric phenomena. They provide very good thermal insulation of the building, which in the summer prevents too much sunlight in the rooms, and in the winter it results in significant heat energy savings.

In addition, they increase sound insulation, perceptibly reducing noise levels in the rooms.
