Up and over garage doors are the most popular type of door available.
They are very versatile and are available in a wide range of materials and designs.
These include steel, fibreglass, Upvc and most types of timber.
There are two main types of up and over door.
These are Canopy and Retractable.
Their mechanisms and the way the panels open and close are different and both types have their uses for specific applications.
The canopy garage door is the simplest and most common type of mechanism.
The name is derived from the way that the fully opened door panel protrudes about a third forward of the door opening to form a canopy.
The canopy door gives the maximum drive-through width when open and is the easiest to install.
It is balanced and assisted by torsion springs positioned above the panel on the head of the fixing frame.
This mechanism is not normally used for automatically opening garage doors.
The retractable garage door is fast becoming the more popular type of mechanism.
The name comes from the fact that the panel is retracted fully into the garage when it is open.
The mechanism is suitable for electric operation.
The drive-through width on a retractable mechanism is reduced as the lifting arms sit in between the sub-frame when the door is opened.
The retractable mechanism has adjustable tension springs at the sides which can easily be increased in size and strength to take heavier panels.
Retractable door mechanisms are ideal for garage doors over 8 feet wide and heavier door panels such as hardwood.
Double garage doors always use retractable gear.
General Sizing Information The size of up and over door sizes are always defined by the internal fixing frame dimensions.
This is the frame for used to fix the door panel itself and can be either a timber or steel box section.
The actual drive through width and height of any up and over garage door will never be the same as the ordering size.
The door panel always hangs down in the opening and reduces the height depending on the thickness of the door panel itself and the width can be reduced as mentioned above when using retractable door gear.
The optimum single garage door size is about 8'0" wide (2438mm) to allow easy access of a vehicle, the height depends on other factors such as building restrictions or taller 4 x 4 vehicles but always try for 7 feet as minimum.
