Maxiblock Blockout Shutter


The Maxiblock shutter includes all the features of the original Blockout shutter with the added benefit of increased strength for security applications.

The secret to the Maxiblock shutters strength lies in the heavy duty track and exclusive internal locking chamber which locks the curtain inside the tracks preventing the curtain from being pulled out by intruders or high wind areas.

 The Maxiblock shutter also includes a reinforced bottom bar which prevents the curtain from bending when unwanted pressure is applied.

As with the original Blockout Shutter The curtain is made using a roll formed aluminium slat which is filled with foam to provide excellent insulation properties. All major components are made from powder coated aluminium to provide a long lasting rust free product.

The combination of the foam filled curtain slats and the air gap created between the shutter and the window glass can reduce the heat gain in summer by up to 90% and the heat loss in winter by up to 70%


  • Blockout Heat - keeps the heat out in summer, traps the warmth in winter. Westerly facing windows can make afternoons very uncomfortable, not with Blockout!
  • Blockout Noise - reduce road and other unwanted noise
  • Blockout Light - great for shift-workers and children who need to sleep during the day
  • Blockout Intruders - The mechanical protection and visual appearance of the Maxiblock shutter can prevent, deter and impede unwanted intruders. (For commercial applications we recommend Extruded Maxiblock Shutters)
  • Blockout Wind,Rain & Hail - prevent wind driven rain from entering windows and doors. Shutters can also make verandas and patios usable in when the weather is unpleasant.
