The first windows and door system for Flame Zone living
Warm timber looks for flame zone protection.

SCHOTT Pyranova Fire Rated Glass now plays a significant role in the protection of houses in Australia’s bushfire prone areas. This results window and door manufacturer Paarhammer having successfully developed Australia’s first ever approved window and door system for building in Flame Zone (BAL FZ).

Innovation at Paarhammer knows no bounds. Hard on the heels of Paarhammer’s launch of Australia’s first BAL 40 windows comes the launch of Australia’s first window approved for building in Flame Zone (BAL-FZ) as per AS 3959-2009 and AS1530.8.2. In a major technical breakthrough, Victoria’s multi-award winning regional timber window manufacturer Paarhammer have achieved what has been unattainable until now: windows and doors that do not require additional shutters or fire screens in Flame Zone designated areas. With all the new Australian Standards and local regulations regarding building or renovating in bushfire prone areas (BAL zones) Paarhammer took on the challenge to further develop their famous tilt & turn timber windows, doors and sliding doors to withstand temperatures exceeding 850 degrees over 30 minutes with a cooling down period of 1 hour – thus achieving the required Australian Standards. Fire safety and risk testing was conducted by Exova Warringtonfire Melbourne and the Paarhammer products passed beyond expectations. Readings after the test showed the tilt & turn, sliding and locking operation in perfect working order. The inside of the windows, doors and weather seals showed no signs of the raging fire and heat of the test simulating the highest level of bushfire outside. Radiated heat through the windows and doors did not exceed 6kW, which is less than half of the 15kW allowed by the Australian Standard.

This astonishing result was achieved with locally sourced red ironbark timber, SCHOTT Pyranova® glass incorporated into double-glazing, special seals, and of course, the expertise and determination of Paarhammer Pty Ltd. “This development is very significant for people wanting to build in the highest bushfire prone area”, says Tony Paarhammer, “Up to now there were no windows and doors available at all for Flame Zone. Now we offer a full suite of bushfire safety products from BAL-29 and BAL-40 to BAL-FZ windows and doors as well as our special BAL-FZ shutters. Paarhammer bushfire products give peace of mind without compromising their standing as the highest energy rated windows and doors on the market. Their unique framing, sealing and secure metal-to-metal locking system provide the highest energy efficiency (U-values from 1.1, air infiltration from 0.05) and sound protection of 45dB.

For over 20 years, Paarhammer windows have been setting the benchmark in energy efficiency in Australia. Whether a design calls for stylish contemporary minimalism, bringing a historic building into the 21st century or building in the highest bushfire prone areas, Paarhammer provides compelling solutions for the most demanding residential and commercial projects.
