The strongest shutter on the market

Blockout’s Extruded Maxiblock Roller Shutter is the strongest shutter in our range and the toughest on the market. It is made from a 40mm double walled extruded aluminium profile with a wall thickness of 1.2mm (compared to 0.38mm for standard shutters).  


Exclusive MAXIBLOCK® security system

The Blockout Extruded Maxiblock Roller Shutter not only uses Blockout’s exclusive heavy-duty track, locked in profile and bottom bar security system; it also offers the highest level of security through unique side locking chambers. These internal chambers secure the shutter slats inside the track, making it almost impossible to pull the slats out of position. The result is a roller shutter that provides you with security and protection from:

  • Intruders 

  • Storms 

  • Hail 

  • Strong winds 

  • Bushfires  BAL40

Light control

Blockout Extruded Maxiblock Roller Shutters are custom made, allowing light and ventilation holes to be vertically aligned with each other for better aesthetics and light control. The roller shutter can create a total block out effect or provide a soft filtered light.

Insulation benefits

As an externally fitted shutter, Blockout Extruded MAXIBLOCK® Roller Shutters act as a thermal barrier, creating an insulating air pocket between the shutter and the window. They can:

  • Cut direct sunlight by 81% 

  • Reducing light and glare 

  • Reduce heat gain by up to 70% in summer 

  • Prevent heat loss by up to 70% in winter 

  • Minimise outside noise.


Extruded MAXIBLOCK® Roller Shutters are available in variety of colours.
