Avoiding Renovation Regrets

Avoiding Renovation Regrets

Wednesday, November 03, 2021

Australia's love affair with renovating is expected to continue not only because Australians love to renovate, but also as households increasingly prefer to direct excessive property transaction costs towards improving their existing homes, rather than trading up. Top 5 regrets But renovations can be fraught with issues: according to research by the Victorian Government, the top five renovation regrets are insufficient insulation, air leakage, poor lighting, not selecting double glazing, and poor design. Energy efficiency Windows and doors play a very important role in buildings. They let in light but at the same time protect the home from wind, rain
Difference in U-value Calculations

Difference in U-value Calculations

Wednesday, October 06, 2021

Windows around the world get tested and certified using different criteria: Australia uses the North American NFRC (National Fenestration Rating Council) system, Europe uses ISO 10077-2 and ISO 15099, then there is the Passive House Criteria and ift Rosenheim Directive WA15/2. How do you know you get the best window for your build? One thing is clear: the lower the U-value, the better your window. But if the outcomes of the different methods are not the same, can you compare apples with apples? Is an Australian U-value of 1.1 worse than a European U-value of 0.8? Or is it better or
Claiming energy stars

Claiming energy stars

Monday, November 09, 2020

In a recent article in ‘The Conversation’ some builders are said to use the star rating system in a way that could mislead customers. The same can be said of the window industry. If you are looking for highly energy efficient windows, do not believe claims like ‘best energy efficient windows in Australia’ if this claim cannot be independently proven.WERS – Window Energy Rating Scheme – is the Australian rating system that gives windows stars for cooling and for heating. It also rates windows for their U-value and air-infiltration. The lower the U-value, the higher the energy efficiency of the

Advantages of tilt & turn Windows

Turn your four walls into a home with noticeably high room comfort. Custom made tilt & turn windows by Paarhammer feature several locking points around the window and, together with rebated framing and compression seals, provide high energy efficiency, sound protection and security. While outward opening windows – whether awning or side opening – have issues with space when combined with external roller shutters, they are also difficult to clean from the inside. In this situation flyscreens must be mounted on the inside, and also hinder the cleaning process. Sliding and double hung windows are notoriously draughty even when closed,

Architects Declare - What next?

Monday, November 18, 2019

Imports of building material have been on the rise in Australia in recent years, but has the worldwide Architects Declare movement shone a light on the product of local manufacturers in the respective regions of members? The aim of Architects Declare is to consider the overall impact to the environment when designing structures of tomorrow. Confirming the sources of raw materials, manufacturing methods, and reducing the travelling distance of construction items all impact the overall footprint of each project. Local job growth and the continuing development of skills in Australia is also an important consideration. The range of products still

Architects declare Climate Emergency

Monday, October 07, 2019

Recently hundreds of leading architects in Australia declared a ‘climate and biodiversity emergency’ and joined architects around the world. The group called Architects Declare Australia has as their goal – ‘to ;encourage architects to design buildings that are less wasteful, more adaptable and much more environmentally friendly’. Buildings account for nearly 40 per cent of greenhouse gas (CO2) emissions The group wants to raise awareness and are calling for the urgent need for action in the built environment, and also among their clients and supply chains. Paarhammer is part of this supply chain, making windows and doors. Right from the

Compliance and Industry Updates

Recently the first national conference for members of the newly merged Australian Glass and Windows Association (AGWA) took place at Darling Harbour. A multitude of informative seminars on a variety of topics kept delegates busy, while there were many exhibitors showing their wares. The stand-out topic to take home for us was compliance and the upcoming changes to the industry through the National Construction Code (NCC). Housing Industry of Australia (HIA) gave an overview and outlook of the housing market in all states and territories of Australia, and while detached housing will experience a small drop, it is apartments which

   The Window Energy Rating Scheme (WERS) enables windows to be rated and labelled for their energy impact on a whole house, in any climate of Australia. Paarhammer recently had some of their windows and doors re-tested with different glazing options and achieved excellent results. A Custom Rating on WERS provides an exact rating for a window product, based on its exact materials and specifications for frame, glazing and other components. Weather tightness is based on reported air infiltration data obtained according to the AS 2047 performance test. WERS is independent of any one manufacturer and acts as a fair,

Recently Paarhammer had their Wood-Alu composite window tested, and achieved the highest rating for windows with N6, C4 (general) and N5, C3 (corner) with the Ultimate Limit State Pressure Testing result at +5900 Pa and -5900 Pa. This test as per Australian Standard AS2047-2014 covers Structural Deflection, Air Infiltration, Water Penetration Resistance and Ultimate Strength, and was performed by a NATA-accredited testing facility in Melbourne. Under the National Construction Code (NCC), the Building Code of Australia (BCA) is a set of technical provisions for the design and construction of buildings throughout Australia. It allows for variations in climate, and geological
Bushfire Compliance

Bushfire Compliance

Flame Zone (BAL-FZ) product testing requires successful completion of the AS1530.8.2-2007 test. This test has a 30 minute furnace cycle and a 60 minute cooling down cycle in which the product still has to keep its integrity. Part of the test is also a radiant heat requirement of a maximum of 15kW/m2 on the inside. Paarhammer BAL-FZ products showed a heat flux on the non-fire side of between 1kW/m2 and 2kW/m2 in the test, depending on the product. This is just 1/10th of the allowed radiant heat. To put this into perspective, naked skin can tolerate 5kW/m2 for approximately 10 seconds

Compliance - the next Step

In response to non-compliant building products, the Queensland Government has taken the lead in creating new laws to cover the sale and use of building products, and creating a chain of responsibility. Bunnings Queensland reflects these changes in the updated information on the building products stocked. Compliance information and fitness for intended purpose for a building product must now be provided by each person in the supply chain, to the next person in the supply chain. This includes manufacturers, importers and suppliers who all have a responsibility to ensure that the building product in question is compliant and fit for
