What is an overhead door?
Overhead doors are made of several jointed panels that roll up on tracks above the access or across the ceiling. These doors come with different rail systems depending on the building and the space available. The tracks can either go straight up above the doorway, with a bend towards the ceiling or they can follow the roof pitch. The overhead door is primarily used as a service door but also very popular as a garage door.
Sectional door
The overhead door currently is the bestselling door on the market. It is known by different names such as sectional door, section door or garage door.
History of the overhead door
In the late 70s and early 80s of the last century, overhead doors were introduced as an alternative to non-insulated rolling shutters. Because they consist of insulated sandwich panels overhead doors have excellent insulating qualities. Another advantage was the ability to fill the doorframe with glass panels and the installation of a wicket door. Furthermore, overhead doors are very stable and suitable for relatively large door sizes.
The compact door as an alternative service door
The compact door can be regarded as an overhead door because the door panels are stored ‘overhead’ when the door is open. From the outside, it even looks like another overhead door, but all the difference is made on the inside. The main advantage is that the compact door is a folding door. This means that it saves a lot of space.
