The latest fire and smoke reduction window systems for bushfire-prone areas

Australia–   Australia is known for its dry heat, scorching sun and unparalleled track record for devastating bushfires. Fires caused by electrical faults and kitchen accidents are also quite common in our country and they too threaten devastation to Australian lives and families.

In the month of October 2013 alone, over 100 fires wiped out a total of 118,000 hectares of land and almost 300 homes across the state of NSW. More recently, we saw similar devastation from bushfires along the Victoria’s Great Ocean Road and across various regions in Western Australia.

And while these instances are just part-and-parcel of living in Australia, a lot of the damage caused by these fires to property and buildings could have been avoided had certified fireproof and smoke reducing building products been used when they were constructed, and had best-practice design of buildings in bushfire-prone areas been followed.

One of the major hurdles facing designers of homes in bushfire prone areas is the perception that building to high Bushfire Attack Levels (BAL) is difficult and expensive, another is that our most common and low-cost building materials are not suited for these areas.

The most commonly specified windows in Australia for example are either standard aluminium or timber frames, both of which are highly combustible and encourage flames and smoke to spread at a fast rate in the case of a fire. Glass windows, if not properly treated, can also be a hazard in their own right as sudden rises in temperature can see glass crack, shatter and fracture from the severe stress.

But mandatory design standards for Construction of Buildings in Bushfire-Prone Areas (AS3959) means highly-combustible windows are things of the past and, suitably, we’re now seeing window frame and glazing manufacturers produce new lines of products designed to combat or resist the threat of building fires in line with AS3959. These specialised ranges of window and door systems offer smoke and fire reduction and control and include seals and sealing systems, fire rated frames, doors, windows and glass panels.

Other than AS3959, Australia also has product standards for fire reduction and resistant performance. All products claiming to be fire safe and rated to building standards and regulations should state exactly what regulations and requirements they meet, as well as being able to provide technical and specifications to ensure peace of mind and complete confidence in the product selection and suitability of application.

Standards and guides include:

-AS 3959:2009 Construction of Buildings in Bushfire Prone Areas
-AS1530.4 Fire resistance tests of elements of building construction
-AS1530.8.1 Tests on elements of construction for buildings exposed to simulated bushfire attack – Radiant heat and small flaming sources
-AS1530.8.2 Tests on elements of construction for buildings exposed to simulated bushfire attack- Large flaming sources
-AS1851 Maintenance of fire protection systems and equipment
-AS1905.1 Components for the fire protection of openings in fire resistants walls Part 1: Fire Doors
-Bushfire Attack Levels (BAL)
-Building Code of Australia (BCA) Flammability Index, Spread-of Flame Index, Smoke Developed Index

The following are products that provide various levels of fire protection, reduction and control.
