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.

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.

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.

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.

Architects and Building Designers are tasked with the most important objectives; managing client expectations, design intent, – and of course budget all within site parameters and building compliance.

When it comes to achieving or exceeding a 7-star energy rating as part of the National Construction Code, few of these choices offer as much scope for variation and flexibility as the selection and application of window and door systems as a major component of the thermal envelope of the building.

Well specified windows and doors can be the difference between a thermally efficient design which comes in on budget versus an over engineered, high performing build that can confuse the most experienced specifier and possibly exceed budget – perhaps unnecessarily.

Thermally broken windows have long held the title of one of the most energy efficient solutions by offering the broadest application for use. By insulating the pathway for thermal transmission through the window frame, it’s a clever way to make the most from the durability of aluminium while reducing its conductivity – but extra components inevitably mean more assembly and a comparatively higher price tag.

So, is there a cost-efficient way to maximise energy gains, while maintaining strength and design flexibility without turning to thermally broken windows?

That’s a question both asked and answered by leading supplier of aluminium windows and doors, AWS (Architectural Window Systems). This fundamental question was asked over 10 years ago and it led to the development of a more cost effective, energy efficient solution which also offers a contemporary design aesthetic in the current market.

Cue ComfortEDGE™

ComfortEDGE is an elegant, double-glazed solution for residential applications that rivals the energy efficiency of thermally broken products. Its embedded frames provide a sleek design comprising fewer components than thermally broken counterparts, making it a cost-effective, wholly Australian made option for Australian projects. ComfortEDGE recognises that clever design doesn’t have to be complicated, and skilfully minimises the amount of exposed frame by embedding into the timber reveal, insulating against the environment to improve energy efficiency and thermal comfort.

ComfortEDGE truly is the perfect meeting point of form and functionality. It’s stylish and high performing, with U Values as low as 1.9 – placing you in the best position to meet 7-star energy provisions while keeping your budgeton track.

Back to weighing up your options… How will you know if ComfortEDGE is right for your project?

AWS recommends consulting your specification expert early in the design process, taking a holistic approach to build sustainably and to meet energy compliance on budget. For designers looking to harness the vast possibilities afforded by Australian designed and manufactured architectural windows, give your AWS specifier team member a call and reap the rewards.
