BAL40 tests were performed on the following CityView window and door systems from Darley Aluminium:

• CityView Patio Sliding Door
• CityView Sliding Window
• CityView Architectural Door
• CityView 35mm Awning Window
• CityView 50mm HD Awning/Casement Window
• 100mm x 50mm Single Glazed Framing

BAL40 refers to the Bushfire Attack Level (BAL) protection of your building from burning embers ignited by windborne debris and exposure to a high level of radiant heat up to and including 40 kW/m².

Warringtonfire conducted the BAL40 test in March 2022, in accordance with the requirements outlined in the current Australian Standard AS1530.8.1.2018.

Other systems have been tested to the superseded Australian Standard, while our CityView systems have been tested to the newer and more stringent 2018 standards.

To simulate more accurate fire conditions, Tasmanian Oak was used instead of the traditional pine cribs, resulting in higher burn temperatures.

The above mentioned CityView window and door systems exceeded testing requirements and were able to withstand temperatures of up to 40kW without compromising the frame and glazing systems.

CityView window and door systems are rated to BAL40 and provide protection from ember attacks, burning debris and exposure to flames.
