Acoustics Product Testing

Hero-Home

As more people opt for city living, developers are building more high-density dwellings than ever before. With units in close proximity to one another, the need to insulate dwellings from exterior noise has become an important consideration in the selection of building products.

The development of high performance window and door systems which provide improved acoustic performance has become more prevalent in recent times as architects, builders and homeowners seek acoustic tested systems to reduce the impact of traffic, aircraft noise, and entertainment systems. Acoustic privacy in many properties has become a major concern.

Local governments have introduced regulations to address the problem; in some instances local municipalities have their own regulations or guidelines regarding noise abatement. Many projects are now required to meet strict acoustic specifications

The Weighted Sound Reduction Index (Rw) is a number used to rate the effectiveness of a soundproofing system or material. Rw values represent aggregated data showing the average performance of a window across a broad spectrum of sounds. Increasing the Rw by one translates to a reduction of approximately 1db in noise level. Therefore, the higher the Rw number, the better a sound insulation the element will deliver.

Architectural Window Systems (AWS) has conducted extensive research and testing on our aluminium window and door systems to evaluate acoustic performance and determine Rw values for our systems with various glazing options. We test our systems in a chamber that has 100 decibels of varying sound frequencies coming through the speakers. This volume equates to an aircraft taking off nearby, jackhammer 2 metres away or a heavy truck or horns nearby.

The test chamber is fully insulated and certified by the National Acoustics Laboratory. On the inside of the test chamber, there are microphones that measure how much sound is leaking through your product. After a specified time, you are given an end result measurement for your product.

Through considered innovation, AWS offers a of windows and doors from the Elevate™, Vantage and ThermalHEART™ brands to assist in insulating the building envelope from unwanted noise – making it easier to create beautiful living spaces which meet contemporary aspirations for efficiency and comfort.

Detailed acoustic test reports show the full spectrum of sounds from both high frequencies and low frequencies, and are available for all acoustic tested AWS systems. If you are working with acoustic engineers that require further data, you can source it from your local AWS Specification Representative or authorised AWS manufacturer.

AWS Supports OzHarvest to Help Nourish Our Country

After a demanding year for many across our communities, AWS is proud to share that we have made a festive season donation to OzHarvest, Australia’s leading food rescue organisation, which will provide thousands of meals to Australians in need.

Thank you for reading this post, don't forget to subscribe!

A growing need in our communities

Food insecurity in Australia is rising at an alarming rate. Last year, an estimated 3.5 million households struggled to put food on the table, with the cost of living now the number one driver of hardship. The charities OzHarvest supports say they could distribute double the amount of food to meet demand. Every day, new people are turning up for help, often feeling ashamed or embarrassed to ask.

James from St Albans Community Youth Club in Victoria, which receives OzHarvest food weekly, put it simply: “For the first time in 10 years, we’re struggling to feed everyone.”

Why the festive season matters

The festive period can be especially difficult for families who do not know where their next meal is coming from. Demand typically spikes at this time of year, even as household budgets are stretched further. OzHarvest is working hard to ensure nourishing food reaches those who need it most, not just during the holidays but all year round.

About OzHarvest

OzHarvest was founded in 2004 by Ronni Kahn AO, after she noticed how much quality food was going to waste through her events business. What began as a simple, practical solution rescuing surplus food and delivering it to charities quickly grew from one van in Sydney into a nationwide movement. As OzHarvest expanded, Ronni and a team of pro bono lawyers successfully lobbied state governments to change legislation so food donors could give surplus food to charities without fear of liability. NSW led the way with the Civil Liabilities Amendment Act in 2005, and other states followed.

Today, OzHarvest rescues food at scale with a clear purpose to Nourish Our Country. Their mission is to stop food waste, feed people in need, and protect our planet by championing the value of food and driving change at every level of society. Their work strongly aligns with five United Nations Sustainable Development Goals.

How you can help (if you would like to)

OzHarvest welcomes every contribution. The impact is immediate and tangible.

  • $1 = 2 meals
  • Your donation helps keep OzHarvest’s wheels turning
  • It supports food relief for over 1,500 charities helping vulnerable Aussies every day

AWS Sponsors Building Tours at Glenn Murcutt Foundation Australia Symposium

Architectural Window Systems (AWS) is proud to sponsor the Murcutt Building Tours, a centrepiece of the inaugural Glenn Murcutt Architecture Foundation Symposium, to be held in Sydney from 11 – 13 September 2025.

Thank you for reading this post, don't forget to subscribe!

The Symposium, presented by the Murcutt Foundation, celebrates more than five decades of architectural practice by Glenn Murcutt AO, Australia’s most celebrated living architect. The program offers three days of tours, talks and events for architects, students and design professionals, culminating in a rare opportunity to engage directly with some of Murcutt’s most acclaimed works.

As part of its ongoing support for architectural excellence and sustainable, place-based design, AWS is sponsoring the Murcutt Building Tours on Thursday, 11 September, providing a rare, guided experience led by Murcutt himself through two iconic residential projects:

  • Nicholas House
  • Simpson Lee House

“I am so pleased that so many have taken the chance to see these two projects that were designed in such close collaboration with the clients at the time, and which have been so well loved and cared for over the many decades since. It is such a joy to share this work,” Glenn Murcutt AO.

“Glenn Murcutt’s works embody a profound sensitivity to landscape, climate and material — and they are best understood by being experienced firsthand,” said Angela Bevitt-Parr, National Marketing Manager at AWS. “AWS is proud to support this extraordinary opportunity for architects to deepen their understanding of Murcutt’s work and philosophy through direct engagement with these exceptional places.”

Beyond the tours, the Symposium will feature keynote addresses from Glenn Murcutt AO and Francis Kéré (fellow Pritzker Prize Laureate), the inaugural awarding of the Murcutt Pin, and a full day of talks exploring the themes that have informed Murcutt’s unique model of practice.

“Francis Kéré is one of the great humans, and a gifted architect who really shows architecture can make a difference in people’s lives. I have a huge amount of respect and time and a wonderful friendship with this man because of his integrity. I am so pleased that Sydney will get to meet him this year,” Glenn Murcutt AO.

Designing Value – AWS celebrates 30 years

In late 1994, two dedicated fenestration professionals, Gavan Pead and David McCleary, took a pivotal tour of Architectural Profiles Ltd (APL) in Cambridge, New Zealand. Inspired by APL’s customer-focused business model, they envisioned bringing a similar approach to challenge the Australian market’s basic, outdated aluminium windows and doors that dominated at that time.

Thank you for reading this post, don't forget to subscribe!

This vision led to the founding of Architectural Window Systems (AWS) in January 1995, with Pead as the first General Manager and McCleary as Head of Design. AWS launched with the release of the 502 sliding window and 541 sliding door – affordable, single-glazed products that immediately stirred the market. “In those days, profiles were hand-drawn, and every detail required precise verification,” McCleary recalls. Their commitment to quality was matched by strong supplier support, relationships that remain solid today.

To bring this customer-centric model to life, AWS built a robust network of independent fabricators across Australia, now exceeding 200, with unparalleled reach and service capabilities. Steve Butcher of Great Lakes Glass, an early adopter, recalls that “their passion was infectious, and if they were starting something new, I wanted to be part of it.”

AWS quickly became a trusted name in high-performance aluminium windows, with products designed to meet the needs of architects, designers, builders, and homeowners. With the launch of ThermalHEART™ in 2007, followed by ThermalHEART™ commercial in 2012, AWS introduced its first thermally broken products, raising the bar for energy efficiency. In 2003, David’s son, Mark McCleary, joined AWS, continuing the family’s involvement in the company. In 2021, Mark took over the leadership of research and design, guiding the development of innovative window and door solutions. That same year, AWS introduced ComfortEDGE™, a significant step forward in thermal efficiency. With additional ComfortEDGE™ products set for release in 2025, AWS continues to strengthen its commitment to energy-efficient solutions for the Australian market.

Reflecting on the success of the last 30 years, AWS General Manager Greg Taylor notes that “it’s our model that differentiates us. A supplier that is not only an extrusion supplier, but a reliable, supportive, engaged business partner that understands the need for continuous improvement”.

In 2025, AWS will continue to focus on improvement, introducing a class-leading digital environment for specifiers, fabricators, and staff, along with an automated workflow connectivity solution exclusively for AWS fabricators.
