Why Windows May Fail

Tuesday, February 18, 2025

Mistakes in window installation can lead to drafts and/or water egress, or windows that do not work well. Correct flashing, fixing and gap sealing are extremely important. But it starts even before a window gets on site, with the correct installation of the glass into the sash, so the double/triple glazed glass units (IGU’s) do not fail.Mistake 1) Using the wrong support blocks while glazing:Wrongly positioned support blocks or blocks that are not load bearing may cause the window frame or sash to sag and deform. This could affect the seal, leading to condensation within the IGU. Support blocks must

Building in Bushfire Prone Areas

Wednesday, November 20, 2024

With bushfires already started early for this summer, it is important to know what to expect when building in one of the higher bushfire prone areas. And it is not necessarily ‘bush fires’ but also ‘grass fires’ that can be dangerous to homes. If you plan to build in a BAL rated area, you will require a Bushfire Attack Level (BAL) assessment. Bushfire Attack Levels – BALs There are 6 BALs that range from BAL-Low, BAL-12.5, BAL-19, BAL-29, BAL-40 to BAL-FZ. The higher your BAL, the more expensive your new build (or extensive extension) will be, and the more important

Choose Windows Wisely

Thursday, October 31, 2024

With windows being a significant cost factor of a new home, it is worthwhile to start your decision-making process early. Already at the design stage, consider how the build will work, how the position of windows and doors will allow for airflow through the space, and how and where doors will provide access. Design for natural light and solar heat gain in winter, and shading requirements in summer, and plan carefully with current and future needs in mind.Building EnvelopePriority must be given to creating a well-insulated building envelope - walls, floor, roof and windows. All these are items that should

Staff are Paarhammer’s greatest asset. With much pleasure, we recently celebrated a 20-year work anniversary and a 30-year work anniversary.

She became indispensable as Office Manager and Personal Assistant to Tony, the Managing Director. Judy (centre) with Edith and Tony Paarhammer. Andy started as an apprentice in 1994. He worked his way up to become Production Manager and organised the workflow in the factory for many years.

Window = Frame+Glass+Hardware

Wednesday, July 31, 2024

Windows are an important part of any building and have to comply with several Australian Standards (AS). This is the reason why windows are made as a whole system where frame, glass, and hardware, are designed as a unit to achieve the required results. If any part of such a system gets changed, it will not comply with the AS’s anymore and become a ‘deemed to satisfy’ or ‘engineered solution’. When hardware details, profile details, or any components are changed, or the overall size is made larger compared to tested sizes, the window system may no longer be compliant and

American Oak Windows

Wednesday, June 19, 2024

Paarhammer is now in full production of American Oak windows and doors. Since Victorian Ash is no longer available due to the Victorian Government ending native timber harvesting, American Oak was chosen as its replacement for high-performing window products due to its colour, grain, strength and sustainability. American Oak – Quercus Rubra – is a blond, medium density hardwood of about 730kg/m3 with a straight open and even grain, and uniform texture. Windows and doors made of hardwood are naturally hard-wearing, strong, energy efficient and visually stunning. American Oak has itself a BAL-rating of 19, but should higher BAL-ratings be

Window Development 1950’s to today

Monday, May 27, 2024

The building industry in Australia represented by HIA and Master Builders are addicted to low cost windows. From the 1950’s onwards, glazing became cheaper and allowed architects to frame views and bring light into the building. Also, builders realised that windows at that time per square meter were only about half the cost of a wall. So with using more glass, one could construct cheaper buildings. As a solution to keeping such glasshouses at a liveable temperature, larger air-conditioning systems were required. Central Europe: Houses and windows in Europe developed quite differently. In the alpine region already a couple of centuries ago they

Compliance: Insights and Pathways

Thursday, April 18, 2024

The integrity and compliance of building components are paramount to ensuring health, safety and sustainability in the evolving landscape of the building industry. Among these components, windows play an essential role in the structural and environmental performance of buildings. Poorly manufactured or standard windows lose more heat in winter and gain more heat in summer than any other surface in a building. This whitepaper delves into the multifaceted dimensions of window compliance within Australian standards and regulations, highlighting the economic, legal and social implications of non-conforming and non-compliant building products. It underscores the importance of rigorous independent testing and certification processes
