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 applying additional fire safety measures, calculated by the suburb you live in & the risk of fire danger in that area. These ratings are called Bushfire Attack Levels, or BAL for short. BAL-40 is one of the highest levels of protection you can receive, your local council will advise you of your BAL rating, every homeowner or tenant should be aware of their BAL rating so they ensure the home has the relevant protections and make an appropriate fire safety plan . Windows and doors are designed so that the complete unit works together as protection, including fire-resistant coatings, optimum glass thickness and screen fittings.
