Our ALU-12M411 come insulated which make them the perfect product for customers who want to save on energy bills as they keep the heat in, cold out or vice versa depending on that time of the year they are used. They are also used as “high quality” curtains and block out nearly 100% of all light – ideal for those of you living in big cities or busy towns.
The canopy where the shutter rolls into can come as a square or rounded option depending on your preference. 
Comes in 7 standard colours: White, brown, cream, fir green, grey, silver or black. We also have both vented & non-vented options.
For larger openings please see the “big brother” of this model, our ALU-12M511.

  • Offers low to medium security 
  • The ALU-12M411 traditionally offers a more cost effective and aesthetically pleasing solution to that of an insulated steel shutter.
