The system of external blinds monobloc is a combination of positive features of external blinds + perfect combination of blinds with the window. The roller shutter box and guides are made of PVC. This box is mounted above the window. From the outside, it is suitable for facade treatment and from the inside for dry or wet plaster, which makes it completely invisible.
The box contains an additional layer of styrofoam which completely eliminates the risk of frost. In spite of the complete construction of the box, its construction (bottom and front inspection flaps) allows the repair of the shutter without interfering with the façade or interior plasters.
This system is recommended for newly buildings in which the window opening has been enlarged by the height of the roller shutter box or to existing ones, however, at the expense of the height of the window.
