Every building loses some of its thermal energy to some degree. Windows, doors and garage gates are places that are exposed to the biggest losses of heat. These elements we should focus on, thinking about saving energy. External blinds are an effective way to improve the energy balance of a building and to save realistically.
The shutter system that is sometimes called topped or overlaid, and also embedded shutters are solely utilised while building from scratch or at windows replacement in existent buildings.
These, while planned in the building blueprints will improve its image and insulate it considerably. The window box is embedded in the lintel and the guide rails in the window recess. It enables to cover the shutter box and insulate it perfectly so there are no so called thermal bridges. The shutter box is invisible as a result and shutter seems to be one with a window.
The system enables to install a service cover in the lower part of the box (the box installed outside) or in the front (the box installed in the broad window frame). It is possible to operate the shutter both manually by pulling the stripes or electrically with a RC. It consists of two support walls, which enable better thermal insulation, and its stiffness prevent the box from bending while installing.
