Frequently Asked Questions

What are the specific Australian Standards for commercial door accessibility?

In Australia, commercial doors must comply with AS 1428.1-2021, which outlines the requirements for design and mobility access. This standard specifies that doorways must have a minimum clear opening width of 850mm to allow for wheelchair access. Furthermore, the threshold must be level or have a compliant ramp, and the hardware—such as handles or D-levers—must be operable with one hand and located at a height between 900mm and 1100mm. Ensuring these standards are met during replacement is a legal requirement for Australian businesses to provide inclusive access to all members of the community.

How do fire-rated commercial doors differ from standard doors in Australia?

Fire-rated doors are engineered systems tested under AS 1905.1 to resist the spread of fire for a specific duration, known as the Fire Resistance Level (FRL). Unlike standard doors, these units feature a specialised core, intumescent seals that expand when exposed to heat, and fire-resistant glazing if applicable. During replacement, it is crucial that the entire assembly—including the frame and hardware—is certified as a single unit. After installation, a compliance tag is usually attached to the door leaf to verify its fire rating, which is essential for passing annual fire safety audits in Australian commercial buildings.

Why is an “airtightness” check important for commercial doors in the Australian climate?

With Australia’s increasing focus on the Nationwide House Energy Rating Scheme (NatHERS) and commercial energy efficiency, sealing is paramount. A poorly sealed door allows conditioned air to escape, significantly increasing electricity costs during hot Australian summers. During the replacement process, high-quality perimeter seals and automatic “drop seals” at the base of the door should be installed. These components not only improve thermal efficiency but also act as a barrier against dust, insects, and noise, creating a more controlled and comfortable internal environment for employees and customers alike.

Can I reuse existing hardware on a commercial door replacement?

While it is technically possible to reuse handles, locks, or closers, it is generally discouraged during a full commercial door replacement. Existing hardware may have internal wear that isn’t visible, or the mounting holes might not align perfectly with the new door’s reinforced points, compromising the door’s structural integrity or warranty. Furthermore, in 2026, many Australian businesses are upgrading to smart access control systems. Replacing old hardware ensures that the new door operates at its peak mechanical efficiency and allows for the seamless integration of modern security technologies like biometric or RFID readers.

What is a “door closer” and why must it be adjusted correctly?

A door closer is a mechanical device that ensures a commercial door closes automatically after being opened. In Australia, correct adjustment is a safety requirement; a door that slams can cause injury, while one that doesn’t close fully can compromise fire safety or security. The adjustment involves two main speeds: the “closing speed” (from fully open to about 15 degrees) and the “latching speed” (the final few degrees). Ensuring the door closes firmly enough to engage the latch without excessive force is a critical final step in the replacement process to maintain the building’s safety and thermal envelope.
