Flame zone-approved windows and doors
Paarhammer has developed windows and doors that do not require additional shutters or fire screens in Flame Zone-designated areas.
Previously, the Australian Standard for buildings in bushfire-prone areas (AS3959-2009 and AS1530.8.2.) allowed only windows combined with a screen system for buildings in the highest Bushfire Attack Level (BAL-FZ).
That was until Paarhammer succeeded in enabling its tilt and turn timber windows, doors and sliding doors to withstand temperatures exceeding 850 degrees over 30 minutes with a cooling down period of one hour – thus achieving the required Australian Standard AS1530.8.2.
Paarhammer’s products passed fire safety and risk testing, which was conducted by Exova Warringtonfire Melbourne, to AS 3959-2009 and AS 1530.8.2. Readings after the test showed the tilt and turn, sliding and locking operation in perfect working order, according to Paarhammer.
The company states that the inside of the windows, doors and weather seals showed no signs of damage from the fire and heat of the test, which simulates the highest level of bushfire. It adds that radiated heat through the windows and doors did not exceed six kilowatts, which is less than half of the 15 kilowatts allowed by the Australian Standard 3959-2009 and AS 1530.8.2.
“This development is very significant for people wanting to build in the highest bushfire-prone area. Up to now, there were no windows and doors available at all for Flame Zones. We developed these products to help keep people and property safe during bushfires,” says Tony Paarhammer, managing director at Paarhammer.
The company was awarded Best Use of Windows and Doors in Commercial Buildings at the Australian Windows Association’s conference. Paarhammer received the award for its work on Saffire Freycinet, a new coastal sanctuary on the east coast of Tasmania.
