History of the overhead door
Overhead doors were introduced onto the market last century, during the late '70s and early ’80s, as an alternative to uninsulated roller shutter doors. The overhead door had excellent insulating qualities as the door leaf could be constructed using insulated sandwich panels. It also offered other advantages such as the possibility of installing large glass panels and additional personnel entry doors in a door leaf.
The main advantage when using an overhead door is the excellent insulation it provides. An overhead door has many different design variations which can include glazing or a personnel entry door. The door is stable and suitable for relatively large door sizes.
