Double skinned foam filled lath curtain Roller Shutter. This is an alternative to the Insulated Sectional door where there is no headroom for top tracks and spring assemblies. This door can also be installed externally but would require a canopy or Hood to cover the barrel assembly.
This is the same operation as a single skin roller shutter, but care should be taken to allow for an increase in the barrel diameter when the door is in the open position. Normally Electrically operated either 3 or 1 phase motor.
Doors can be finish colour to standard RAL or BS colour.
