The interior atmosphere is a very important part of life. Aluplast external roller shutter systems can not only be an additional protection for your homes, but will undoubtedly contribute to creating a unique atmosphere inside. In the era of building with a significant number of glazed areas in the body of the architectural structure, external roller shutters are an essential addition to the house, offering a number of tangible benefits. 

Protection against temperature fluctuations

It has already been demonstrated on more than one occasion that fitting windows with roller shutters can make a significant contribution to reducing the thermal inertia of a room. In winter, the layer of air remaining between the glass and the armour of the lowered roller shutter (the so-called air gap) acts as an insulator and provides measurably better protection against heat loss. This has a significant impact on reducing heating costs – savings can be up to 40%. In summer, lowering the roller shutters over windows, in rooms with high exposure to sunlight, prevents these rooms from becoming too hot. This in effect solves the issue of cooling them to comfortable temperatures, which also translates into real savings.​​​​​​​

Sound insulation

For buildings located in high-traffic areas such as stations, thoroughfares, airports, etc., noise protection is becoming increasingly important. A correctly installed external roller shutter, when lowered, can reduce the level of sound entering the interior by up to several decibels.​​​​​​​

Privacy protection

With external roller shutters, you can effectively protect yourself against unwanted glances from outsiders. It is a solution that guarantees a clearly defined zone of privacy and separation from the outside world.​​​​​​​

Compatibility

This assumption, which is valid for the profile system programme, also applies to the external roller shutter system. They can be mounted on all Aluplast system window profiles, as well as on any other window profile after using a special connector.​​​​​​​

Wide adaptability

The variety of forms and materials used in the production of roller shutters offers unlimited possibilities of application (single-family buildings, apartment buildings, commercial buildings, industrial facilities). The extensive range of colours of aluminium roller shutters (RAL colour palette) and the constantly enriched list of available veneers for PVC roller shutters make external roller shutters an important decorative element of modern buildings, irrespective of their utilitarian functions.​​​​​​​
