CityView Window and Door systems rated for BAL40
Darley is pleased to advise that the following BAL40 tests were recently performed on the following CityView systems:
BAL40 refers to the Bushfire Attack Level (BAL) protection of your building from burning embers ignited by the wind borne 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Other systems have been tested to the superseded Australian Standard, while our CityView systems have been tested to the newer and more stringent 2018 standards.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 is used instead of the traditional pine cribs, resulting in higher burn temperatures – change the arrangement to emphasize the point of more accurate fire conditions.
The above mentioned CityView window and door systems exceeded testing requirements and were able to withstand temperatures of up to 40kw without compromising frame and glazing systems.
The CityView range of window and door systems are rated to BAL40 and provide protection from ember attacks, burning debris and exposure to flames.

Bushfire Attack Levels (BAL)
| BAL Levels | Description | CityView window & door systems compliance |
|---|---|---|
| BAL - LOW | There is insufficient risk to warrant specific construction requirements. |  |
| BAL - 12.5 | Ember attack | |
| BAL - 19 | Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 12.5 and 19 kW m2. | |
| BAL - 29 | Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux between 19 and 29 kW m2. | |
| BAL - 40 | Increasing levels of ember attack and burning debris ignited by windborne embers together with increasing heat flux with the increased likelihood of exposure to flames. | |
| BAL - FZ | Direct exposure to flames from fire front in addition to heat flux and ember attack. |  |
