OB700 / OB700 Solar

Aesthetically concealed built-on roller shutter

Built-on roller shutters offer great insulation, reduce street noise and integrate perfectly with your home’s exterior wall. But built-on roller shutter OB700 goes even further. This gem is super-insulating and completely concealed both inside and out.

Concealed indoors and out

Built-on roller shutter OB700 is aesthetically concealed: the box cannot be seen indoors or out, creating a very sleek look.

Strong thermal insulation

Built-on roller shutters offer optimum thermal and acoustic insulation, improving your home’s energy efficiency and significantly reducing street noise.

Dimensions up to 11 m²

At up to 11 m², built-on roller shutters also improve your privacy. They limit the view from outside, discourage burglars and reduce street noise.

A colour to satisfy every desire

Tailor your roller shutter to match the exterior joinery. The box, guide rails and bottom lath are available as standard in all RAL colours and in a great range of textured paints. There is also a wide range of colours for our top-quality slats in PVC or aluminium.

Go 100% sustainable

Why natural cooling

Our mission statement, “We Believe in Natural Cooling,” lies at the heart of all our efforts. We consider smart solar shading to be the most natural and energy-efficient way to block heat. Compare it to a tree providing shade: just as you seek natural cooling under the branches of a tree, sun protection keeps the sun out and your home, patio and workplace pleasantly cool. It offers natural air conditioning for your home which is healthy but also environmentally-friendly.
