Fast closing rates and enhanced sealing properties of high speed doors provide a barrier to unwanted heat (or cold) in an environment. But controlling an environment is not limited to containing internal conditions. 
According to Andrew Bykersma from Albany Door Systems, traditional doors are often left open or cannot cope with the high cycle nature of industrial facilities. 
"By controlling an environment a customer can reduce energy consumption through efficiency of refrigeration or heating. This will now become more critical than ever due to the carbon tax and an increase in the cost of refrigerant gases," he adds. 
According to Bykersma, Albany also has a range of doors which incorporate insulation to the doors curtain which provides additional protection from temperature loss. 
Moving beyond temperature control, a high speed door will also act as a means of contamination control by reducing and eliminating the ingress of dust, pollution, pests and rodents, Bykersma says. 
Materials must therefore be durable, and the door should seal tightly, without any gaps from unwanted pests or pollutants to pass through. 
A few new trends and technologies are also emerging in the safety of industrial doors. "For example, the pre-running photo cell on Albany's Rapid Roll 3000 model travels down in front of the doors curtain to ensure that the door will retract/reverse before coming in contact with any object in the doors path," Bykersma says. 
Need for speed

High speed doors also aim to improve traffic flow in factories and other manufacturing facilities. Some fast rolling doors on the market have opening speeds of 9m per second without frequency inverter, and even 10m per second with frequency inverter.
Mil Lozanovski, the MTI Qualos national sales manager says design features such as top air seals aims to reduce the gap between the building wall and the door to prevent energy loss.
He also points out that a door moving practically non-stop must also be highly durable. The modern frequency inverter control system provides the door with a "soft" start on opening, and a "soft" stop on closing, he says. This means, even in continuous operation, barely any wear and tear occurs, resulting in minimal maintenance.
Keeping intruders out
Another key purpose of industrial doors is, of course, security. Important features to look out for here include: reliable operation to provide suitable barrier and effective integration to facility-wide security systems. The speed of operation can also assist in ensuring there is no unwanted access after entering.
For Assa Abloy marketing communications manager Nick Penny, a key issue is that the process of choosing suitable door hardware and security products is often neglected. The challenge, he says, stems from the fact there are thousands of products of varying quality on the market. And an influx of cheap imports is exacerbating the situation.

The company suggests seeking locks that meet Australian standards to ensure the product has been tested for security, durability and corrosion resistance.
