Trend was showing its Xtreme Bushfire resistant Windows and Doors at the DesignBUILD 2009 exhibition. In addition to special glass, these have high temperature rubber seals (similar to the material used on ovens) and aluminium frames (it is not good if the glass can survive a bushfire but the rubber seal melts). While these may meet standards, established after research such as the Bushfire CRC Report - Windows & Glazing, it doesn't seem a good idea to rely on glazing for bushfire protection on its own. It would make sense to use a metal mesh outside to protect these windows. While the glass might survive the heat of a fire, it could still break due to flying debris, or if doused with water during fire fighting.
