Paarhammer Bushfire Safe Range – for all bushfire attack levels

Combine design freedom with fire safety in bushfire prone areas with Paarhammer Bushfire Safe timber windows, doors, and sliding doors. Compliant for all Bushfire Attack Levels (BALs), including BAL-FZ, without shutters.

Paarhammer Bushfire Safe windows and doors are tested to, and comply with, Australian Standards AS 3959-2018, AS 1530.8.1, and AS 1530.8.2 (and AS 3959-2009). This range is approved and compliant for the highest Bushfire Attack Level BAL-FZ (Flame Zone), and all products are accompanied with compliance certification.

In 2011 Paarhammer began manufacturing the Bushfire Safe Range of windows & doors. With FSC® (Forest Stewardship Council®) certified Manilkara Bidentata (Pacific Jarrah) timber frames, and Schott Pyranova® glass and special seals, compliance is achieved without the need for shutters.

All Paarhammer products are double glazed for highest energy efficiency, and one pane of the glass unit in BAL-FZ products comes from Germany, is 14mm thick and has clear intumescent layers which act like a heat blanket in case of fire, thereby reducing heat transfer to around 6kwh, less than half the 15kwh allowed for in the Australian Standard.

This was recognized by the Australian Windows Association (AWA), and Paarhammer received the ‘Most Innovative Window System’ award for 2012. This award came shortly after being top of the Industry Section at the Victorian Fire Awareness Awards by the Department of Sustainability.

Tilt & turn windows, fixed glass units, hinged doors, entrance doors, sliding doors, stacker doors, and French doors are available to withstand temperatures exceeding 850 degrees over 30 minutes with a cooling down period of 1 hour – thus achieving the required Australian Standards AS 3959-2018, AS 1530.8.1, and AS 1530.8.2. Tests performed by NATA accredited Exova-Warringtonfire.

Paarhammer Bushfire Safe BAL-FZ products are highly energy efficient, provide excellent sound protection, and feature precision made German hardware with multi-point metal-to-metal security locking. Suitable for any design, modern or traditional, BAL-FZ tested and approved timber windows and doors are custom made locally to your specifications (within size limitations), and are available oiled to enhance the natural rich reddish colour or in a range of stained or solid finishes. Made in Victoria and available Australia wide.

Also available, Paarhammer -/60/- Fire Rated Party Wall Windows for shared or adjoining walls. This fire safety product is a great solution to prevent the spread of fire between buildings.

Whatever the bushfire rating, architects, builders, developers and owners can now rest assured that Paarhammer products achieve the highest energy ratings while providing maximum safety and peace of mind.
