Unique benefits

  • Ideal for major renovations and newbuild projects

    The box for a built-on roller shutter is fitted to the window so it can be concealed invisibly in the wall. Therefore a built-on roller shutter should be incorporated into your plans right at the start of the construction or window renovation process. 
  • Durable

    The guide rails are made from sturdy aluminium and the slats are foam-filled for extra sturdiness and a longer service life.
  • Super-insulating box: best U-value on the market!

    The non-insulated box is often a weak link in the building shell. The OB910 Thermo makes this a thing of the past with a U-value of no less than 0,50 W/m²K. The secret of this super-insulating built-on roller shutter lies in a new type of insulation in the box, based on graphite granules. These dissipate the heat radiation by means of reflection and absorption, thereby vastly reducing the transport of thermal energy in the material and improving the insulation value.
  • Super-silent and 40% longer service life

    Choose SilensioTM and your roller shutter will not only be silent but will have a service life 40% longer than a standard roller shutter. The ultra-quiet tubular motor is quieter than any other household appliance! With an almost inaudible ‘soft start & stop’ function, the typical sound of slats clattering together is eliminated.
