Roller shutter systems (roller shutters) are installed on window or door openings and provide protection against prying looks, burglary attempts, noise, and weather. There are three types of roller shutter systems: roller shutters, rolling grills and roller garage doors.

Roller shutter is a roller shutter curtain assembled of narrow (from 36 up to 77 mm) aluminium roller shutter profiles (slats). The curtain is winded into a roll on the tube which is usually placed inside the shutter box. A roller shutter system also consists of guide rails which guide the movement of the curtain, a drive to control the shutter and the locking system. Due to wide colour range, roller shutters can be considered as an important decorative element of the faç ade. More than 30 colour solutions for roller shutters are offered today:

The shutter boxes are also selected depending on the exterior of the building. There are several types of shutter boxes for roller shutter systems: 45° and 20°, round, quarter-round. Exterior shutter boxes can be mounted in ready-built houses as well as during the construction stage.

The shutter box is unseen being hidden inside of the window opening in a previously prepared housing. When the curtain is raised, it seems that there’s no roller shutter system. One of the advantages of roller shutters with built-in shutter box is that they integrate with building frontage without interrupting its style.
