In its lifetime, the humble garage door has taken on many different shapes and sizes. Over the years, technology has provided us with easier ways of using garage entry doors and more efficient methods of manufacturing them. However, the basic types of garage doorway have remained very much the same. This article will examine the kinds of car port doorway available and their functions.
Overhead Garage Door
The typical overhead storage garage has been around since the early 1920s, it was designed by a man called C. G. Johnson, who, incidentally, went on to invent the first electric door openers in 1926 (yes, garage entry door openers have been around for that long). These gates consist of hinged panels, which are lifted by a spring, and a track and rollers. The overhead garage gate is most often seen in the 'roll-up' style.
Single Panel Garage Doors
Unlike the overhead garage entry door, the single panel or monolithic doorway, as its name suggests, is made from one complete panel. However, just like the overhead garage entry door, it opens 'overhead' and functions with a spring and rollers mechanism. A single panel garage entry door is most often seen in the 'up-and-over' style.
Sectional Garage Doors
On the other hand, there are sectional garage doorways, which are usually made from six to eight panels. These doors also slide up and overhead and will typically occupy the same interior space as a single panel door. However, the sectional garage gate has two benefits over its single-paneled counterpart.
First, the sectional gate does not require any outside space to open. Therefore, a car can be parked close to the garage and the door can still be opened. Second, all six or eight of the panels have their own connection to the track, which makes the sectional door much more reliable.
Roller Garage Doors
The roller door is made from a corrugated material, usually steel (although fiberglass is sometimes used) and has either a loaded spring rolling mechanism, a manual pulley or a motor.
These kind of car port doors are often seen in commercial use. Like the sectional garage doors they can be opened without the need for external space. However, they lack any aesthetic appeal and can be troublesome to fix.
All of these types of garage gate can be, and are, made from a variety of materials, including steel, polyethylene, wood or aluminum. Today, most car port door styles can be insulated to provide better energy efficiency and some are made from recycled or recyclable materials.
