Design Freedom

The choice of installing Compact Sectional doors was the task faced by Porsche Centre Melbourne when developing their Car Showroom; the decision was made due to the amount of space which would be saved with the compact folding door design and the transparent flow between the workshop/engineering area and the car showroom itself. To achieve this they created a building in which most of the internal walls were made of glass. However this gave rise to the problem that normal industrial/sectional doors did not correspond with the clean requirements of the design. The necessary space-saving cannot be achieved with a traditional overhead door, and a roller shutter interfered with the freedom of the design. A combination of both had to be the solution.

Solution: Space saving and design freedom combined in one industrial door

When searching for a suitable solution, it became clear that the Compact Sectional door could deal with both requirements at once: its folding system guarantees space-saving and makes it possible to design the door to meet the client’s requirements. With coordinating the use of colour and glazing, the Compact door can be precisely adapted to the design of the building.

In the new car showroom, glass boxes house both the direct dialogue bay and the dynamic testing/custom engineering workshop; the site also contains a car wash. The Compact doors are located at the entrance of each glass box and are fully-glazed and have a powder-coated finish. The carwash also features a Compact door with motors suitable for a carwash. This project shows that an architect’s freedom in designing a building does not have to be restricted by the essential elements installed in that building.

Space Saving

Designing large facitilies, architects are often faced with a major challenge: large facilities often have the need for many access doors which may have varying requirements, i.e. does your design need to integrate crane tracks and mechanical installations such as sprinkler systems and lighting into the building without restricting the use of the building? The equipment often requires, as far as possible, to be installed around the sides of the building and above the door openings, but this gives rise to problems with opening the doors. Traditional overhead door opens above the access or across the ceiling making it is impossible to fit crane tracks, for instance.

Saving space with the Compact folding door compared to traditional sectional doors

With research into sectional door options, you will find that traditional sectional doors may not fit into the building design because they limit the space above the door.  The panels of the Compact folding door fold up above the door opening, saving space and therefore it is possible to install a range of equipment above the door opening without restricting use.

No Overhead Supports


Buildings designed for emergency services such as the fire brigade and ambulance services need reliable access doors that require little maintenance and also have the option of a high-speed motor to open the door rapidly. Fire brigades often require ducts, lighting and other installations to be fitted around the door opening because fire brigade vehicles are parked as close as possible to the exit.

No overhead supports: more space and no balancing springs

With a traditional overhead door, the door blade raises up above the access on rails or moves into the building via a rail system. To open, the door requires clear space above the access to the height of the door. An average sectional door is 3.5 to 4 metres high. If the overhead door is moved into the building it runs on a rail system that either follows the roofline or goes straight into the building. Both options require a complex steel structure. Tensioned balancing springs are used to move the door and ensure that the door opens along the rails. This system has a high failure rate and the balancing springs have to be regularly maintained or replaced. If the springs break it can be a serious hazard.

Compact folding door beats the traditional sectional door

Worldwide, many government bodies have recognised the disadvantages of overhead doors and opted for a different solution: the Compact Sectional Door. This industrial door folds up above the door opening so it requires no steel structure and little space. So the total costs of a Compact door are lower than for an overhead door.

Minimal costs and flexible installation

With the door blade powered by an electric motor the Compact door also has no balance springs, so maintenance costs are minimal. Since the door blade folds up above the door opening it is possible to fit all installations such as ducts or lighting in the immediate area. Besides these practical advantages there are many options and accessories available for architects to put their signature on a building.
