Mangerton | Bushfire Safe & Energy-Efficient


Built in a bushfire prone area with partly BAL-FZ and partly BAL-40 rating, the clients also wanted to achieve very high energy efficiency. Paarhammer Bushfire Safe Range covers it all.


The distinctive window design features horizontal bars on fixed window panes with inset tilt & turn window openings. The build also features a lift-slide stacker door with highlights, fixed windows, and tilt & turn windows.

BAL-FZ Rating and No Shutters

The clients wanted bushfire safe/resistant windows, without the typical design compromise posed by bushfire shutters. Paarhammer’s Bushfire Windows Do Not require any shutters even at the highest exposure level (BAL-FZ).


All window frames are made from FSC certified Manilkara Bidentata with the BAL-FZ windows and doors featuring Schott Pyranova® Glass which is 14mm thick and includes invisible intumescent layers that swell up in case of fire to create a heat blanket to stop radiant heat being transferred to the inside. Watch the testing footage, to see this mechanism in action.



For BAL-40 Viridian Pyro40® glass is used. Both, the glazing for BAL-FZ and for BAL-40, is made into double glazed insulating units (IGU’s) and achieve a very low U-value of 2.2 and 1.7 respectively.

All Paarhammer Bushfire Safe products have been tested, approved and are compliant to AS1530.8.1-2007, compliant with AS3959- 2009 and AS3959-2018 for BAL-40, and AS1530.8.2-2007, compliant with AS3959-2009 and AS3959-2018 for BAL-FZ.


Test reports are available on request and compliance certificates are supplied for each project. See more information on BAL-40 and BAL-FZ.
