Client Feature PRODUCT Innovation BCA & INDUSTRY NEWS Between and over provides the ultimate performance As would be expected, installing a layer of insulation between the framing, and another on top and over the rafter, achieved the best results (see Figure 3 and Table 1). The downside is that it takes longer to install. To view the BRANZ Study Report SR211 go to www.branz.co.nz. BRANZ thermal testing BRANZ has a registered testing facility for measuring the properties of thermal insulation materials. It has staff experienced in the thermal and insulation performance of buildings, and in the measurement of building energy efficiency. Areas of thermal expertise include: • Accredited testing to ASTM C518 and AS/NZS 4859.1 • ASTM C1363 Guarded Hot Box thermal resistance measurement of constructed panels • In-situ measurement of thermal conductivity using large area heat flux sensors • Precision measurement of thickness and loft recovery of fibrous thermal insulation, including ASTM C167 • Suppliers of equipment for thermal insulation thickness measurement • Standing heat loss of hot water cylinders • Double glazing tests to BS 5713 and CAN/CGSB-12.8-M90 • Specific thermal design • Computer modelling of heat flows in buildings • ALF (Annual Loss Factor) method for optimising the thermal design of houses • Combined heat and moisture performance simulation of buildings and structures • Measurement of building energy efficiency • Advice on ways to meet R-value standards • R-value calculations • Australasian WERS calculations.

AWA members lead the way in developing products for bushfire areas With the development and introduction of AS3959:2009 there has been some significant issues with many building materials, windows and doors certainly have been one of the products with some issues. The new standard has prescriptive requirements to meet the different Bushfire Attack Levels for windows and doors, although some of the requirements such as external screens covering the whole window are not always practical. This can obviously limit the types of windows that can be used and may not necessarily be the best solution. The alternative path to compliance is to test products to AS 1530.8.1. If passed by a product it means that the product can be used up to and including BAL 40, or if testing to AS 1530.8.2 and passed by a product, it means that the product can be used in all levels including BAL FZ. The Australian Window Association led a testing program in September 2008 to advance industry knowledge. The indicative tests were performed as initial screening tests to aid AWA members in selecting specimens for future evaluation for meeting both prescriptive requirements and for testing fully to AS1530.8.1 and 2. To date there are two window manufacturers and one glass manufacturer that have tested product, and they are Miglas Windows, Trend Windows and Viridian Glass. Successfully tested to the new Australian test standard AS 1530.8.1, Miglas FireGuard 40 window and door product series achieves compliance with AS 3959:2009, Construction of Buildings in Bushfire Prone Areas, without the need for external screens or bushfire shutters. Developed, designed and manufactured in Australia, Miglas Fireguard 40 has undergone rigorous testing by the Exova Warrington Fire testing laboratory in Dandenong, Victoria, to be approved for use on sites with a Bushfire Attack Level (BAL) of up to and including BAL-40. Miglas Fireguard 40 timber-aluminum composite windows and doors feature aluminum externally to protect from ignition, while internally, timber provides thermal insulation and stability. PyroGuard 40 from Australian glass manufacturer, Viridian, completes the product’s bushfire resistant status by providing a solid barrier against radiant heat transfer and embers. Trend Windows & Doors Pty Ltd and Smoke Control Pty Ltd announces that the Xtreme® range of Bushfire Window and Door products combined with WindowShield Fire Curtains have recently been assessed to full Flame Zone BAL FZ to comply to the highest level in the new Bushfire Construction standards (AS3959-2009 and AS1530.8.2 -2007). In a major breakthrough, the new system which will be called Xtreme® Flame Zone windows and doors System has been assessed by CSIRO to pass the standard test at the absolute extreme BAL FZ level. The System combines Trend® technologically advanced CSIRO tested BAL 40 (1530.8.1-2007) Xtreme® Window and Door system with Pyro-Protec® seals and glazing systems and standard 5mm or 6mm toughened glass and the Smoke Control CSIRO tested (1530.4) WindowShield Fire Curtain to produce the Xtreme® Flame Zone Bushfire System. This latest development is a result of Trend Windows & Doors® ongoing intensive research and development and extensive testing with the CSIRO, aimed at developing cost affordable window and door systems which will withstand the absolute extremes of bushfire attack. The special ultra-thin transparent coating with Viridian PyroGuard 40 minimises the transfer of radiant heat from the bushfire front through the glass and into the home. Even when subjected to radiation levels of 40kW/ m2, less than 3% of the radiant heat is transferred through a window glazed with PyroGuard 40. This not only protects combustible materials such as curtains and furnishing within the home, but also helps to provide significantly increased protection for occupants.

Client Feature Think carefully about termite protection When considering termite management options for your next residential construction project, it is important to have an understanding of the key features and benefits of the product you are going to use – after all you are protecting a significant asset. According to Ian Pegg, General Manager at FMC Australasia, the choice is obvious, “Insist on using the HomeGuard Precision Termite Management System. It’s An example of one of the many HomeGuard Barrier Systems currently used by most leading building companies across Australia because it works. HomeGuard is a new generation, proactive termite barrier that repels and kills termites on contact.” The HomeGuard range has the credibility of being the first ever APVMA registered physical barrier in Australia. It incorporates the leading preconstruction termiticide, Biflex, which is backed by over 20 years of Australian research data. National Sales Manager Chris Hill explains, “HomeGuard will not corrode, split or delaminate like other physical barriers and is built from materials designed to last the life of the building. The HomeGuard System is both user and environmentally friendly, is nonsensitizing and requires no special safety equipment when it is installed”. FMC Australasia’s innovative, tried and proven system blocks, repels and kills termites.
