well done matt,looks well mate
i have fitted a electric insulated roller shutter door and i would highly recommend it ,its really sturdy once its down and all the sections have locked into eachother ,their is no way you would kick it in and it cant be pry[sp] barred from the bottomm as the motor holds it in place ,available in loads of colours .
have to get mine finished now ,going slabbing it tomorow with a mate of mine
