What is BAL-40 WINDOWS & DOORS safety?

To ensure the safety of commercial and residential properties, the authorities and regulators in Australia today have special requirements aimed at the feasibility of additional measures in the manufacture of secure coatings for aluminum profiles. The fire safety of the BAL-40 is the best protection against any kind of fire, even more so when the room is in close proximity to a potential flashover. Windows and doors are designed so that the fire protection system works on all levels, from ventilation modes to fire-resistant coatings, optimum glass thickness and flexible fittings, whose coordinated operation eliminates jamming of the opening in the event of an emergency.

BAL-40 fire safety standards

Let’s find out how it works. The proposed requirements are classified by the Standards Australia Committee FP-020, Construction of Buildings in Bushfire-prone Areas, to supersede AS 3959-1999. The fire safety performance of windows consists of the following characteristics depending on the configuration:


  • Presence of safety shutters as per AS3959-2009 paragraph 8.5.1 depending on window configuration;
  • The profile and fittings must be made of the materials referred to in sections 5.5.1, 6.5.1, 7.5.1, 8.5.1 and 9.5.1), including aluminium (mandatory).  
  • The window system must comply with AS1530.8.1 2007, where the opening sash guard must be made of corrosion-resistant steel or bronze, with a 2mm opening depending on the configuration;
  • Glazing must be made of toughened glass with a minimum thickness of 6 mm (also triple glazing);
  • All parts of the window (blind and opening) must be protected by a metal mesh (anti-corrosive or bronze) with a maximum aperture of 2 mm;
  • All gaskets and sealants around the perimeter of the window must be made of materials with a flammability index of 5 or of silicone.
