Are you ready for bushfire season?
What makes http://www.doubleglazedwindows.net.au/ upvc double glazed windows and doors ideal for use in homes in the bushfire prone areas? Upvc is self-extinguishing and non-combustible and is notoriously difficult to ignite using common ignition sources. When compared to wood, upvc window frames are harder to ignite, are less expensive and lower maintenance. In terms of smoke density, vinyl window frames will behave similarly to wood under smouldering conditions. Upvc has also inhibits the spread of flame, it tends to form a carbonaceous layer or char, insulating the material below, excluding oxygen from combustions. In addition, the hydrochloric acid emitted acts as a combustion inhibitor. In independent tests conducted at Ohio university calculating total heat release at 10 min showed that upvc had 17MJ/m2, much better when compared to wood such as pine at 91MJ.m2 or oak 45MJ/m2. Notably, even though hydrogen chloride is a main combustion product of pvc, the toxic potency of the combustion gases is similar to and definitely not significantly worse than those produced from natural or synthetic materials found around the home.
After reading about the fire resistant properties of upvc windows, it should not surprise you to learn that one of the few properties that survived the Black Saturday Marysville fires had upvc windows. The home was left virtually unscathed, while the nearby properties were lost. The local builder cites extensive use of vinyl in the home from upvc double glazed windows to weather boards in defending it against bushfire.
