Roller garage doors are made up of a 'curtain' of slats which open and close vertically, neatly rolling up into a compact box at the top of the your garage opening. They are operated by a fob - or a button on the control box - which then activates a powerful electric motor.
Because they roll into a compact top box, roller garage doors can free up give you around 25% more space compared to traditional up-and-over garage doors.
