Whether for use in existing roller shutter boxes, in new construction, renovation or as a whole ‘Plug & Play’ system: Our windows and doors can be equipped with any of our roller shutter single, top or stem elements of the brand roma. We use high quality roller shutter and external venetian blinds, made of aluminum, in Germany, and which are available in various shades.

For our complete systems, the size of the roller shutter and external venetian blind mounting boxes depends on the existing masonry (new box / paper box) and the size of the opening or window. Our technical staff computes the optimum for the application result.

The operation of roller shutters and venetian blinds can be electrical or mechanical upon request. Our comprehensive product range offers single, radio, or central control. All sun protection systems are also available with integrated fly screens.
