Why UPVC Windows?
Bushfires Can’t Beat Our Windows!
Our uPVC windows and doors have inherent flame retardancy properties. The window profiles do not support combustion and are in fact self-extinguishing once a flame source is removed. One of the few homes to have survived the 2009 Marysville bushfire in Victoria, had uPVC windows, and PVC was extensively used in other parts of the home. The vinyl weatherboards and window frames escaped any significant damage and protected the house from ember attacks to the interior.
UPVC window frames have been developed and tested specifically to meet construction requirements for designated Bushfire Attack Levels (BAL) within Australian Standards for Construction in Bushfire Prone Areas (AS 3959:2009). uPVC windows with metal reinforcing are permitted in zones classified as up to BAL-29 (where the number represents the heat flux in kW m2) risk. Some uPVC window systems have been independently tested and comply with AS 1530.8.1 which permits their use in zones BAL-40 and above.

Check out the table below to compare the rating of windows and doors you need to keep your home as safe as possible.
| BAL RATING | FIRE RESISTANCE | RISK LEVEL |
|---|---|---|
| BAL 12.5 | Low | Concern of Ember Attack |
| BAL 19 | Moderate | Increased level of ember attack & burning debris, radiant heat up to 19kwm squared |
| BAL 29 | High | Greater risk from airborne burning debris, further risk from radiant heat exposure up to 29kwm squared |
| BAL 40 | Very High | Burning debris ignited by windborne embers & radiant heat exposure up to 40kwm squared |
| BAL FZ | Flame Zone | Direct flame contact from fire front & radiant heat exposure greater than 40kwm squared |
