An insulated roller door has all the benefits of the single skin roller door with a few more to add.
Insulated roller doors can be fitted internally and externally. So if you don't have the headroom in the garage, it's not a problem. The headroom requirements start at eight inches (205 mm) and go up to twelve inches (305mm). Insulated roller doors come automated as standard with a manual option available.
Insulated roller doors are for the security conscious. There are no handles or locks to pick (automated version), making it virtually impossible to gain access through your garage door.
