Portos blinds

Overhead blinds, which can also be called overhead or overlay blinds, are mounted only at the stage of the stage of building construction or replacement of window frames in existing facilities. The box of the shutter in this case is applied to the window or door frame. To the outer part of the window frame are screwed guides, only later the whole set is installed in the window recess. The roller shutter box in the final effect is invisible, and the roller shutter appears to be part of the window.
