Why Australians should choose higher-performing uPVC windows
Written by Super User
Windows play a vital role in regulating temperatures of buildings and their overall energy efficiency, whatever the climate. Energy efficiency is not just about preserving heating in homes in winter; it is also about minimising and preserving artificial cooling in summer.
Today, high-performance windows are increasingly gaining acceptance in Australia as rising energy costs are prompting homeowners to consider the role of windows in their homes.
uPVC (unplasticised PVC, or vinyl-framed) double-glazed windows not only perform well in keeping cold out of a building and heat within; they also work to keep summer heat out and the cool air inside.
Well-established in Europe, the UK and US, where they are the dominant window type used, a key benefit of uPVC high performance windows is their ability to balance optimisation of heating and cooling loads with consumers’ desire for greater natural light.
The excellent thermal insulation of the uPVC frames combined with insulated glass units and airtight sealing mean less energy is needed to maintain an ambient temperature within the home, which is reflected in cost savings, lower energy bills and improved levels of comfort. This makes them an ideal energy-efficient and cost-effective solution for Australian homes where homeowners like large areas of glazing and plenty of natural light.
Research by the CRC for Low Carbon Living reveals that 87% of consumers want a home filled with natural light and 85% want a cool home in summer and a warm home in winter. According to uPVC Window Alliance members, higher-performing window systems (where the U value of the window is less than 2.5W/m2K) are now available in Australia that outperform basic double-glazed windows for a similar cost.
Research conducted by Climate Works for a report, Built to Perform: An Industry Led Pathway to a Zero Carbon ready Building Code, published by the Australian Built Environment Council (ASBEC) in July found that double-glazed windows are one of a number of simple measures to improve building performance that would be cost-effective if undertaken today to meet proposed stronger energy efficiency requirements of Australia’s National Construction Code. The analysis found that upfront costs of such measures would be more than offset by the energy bill savings, reduced spend on heating, cooling and ventilation equipment, and electricity network savings.
Modern uPVC windows are made from a rigid and dense material that is used worldwide for a variety of building products. The multiple chamber construction of uPVC windows gives them excellent thermal performance and strength, plus the frames’ low conductivity limits the transfer of heat and cold. uPVC is roughly 1,000 times less conductive of heat than aluminium. Thermal performance is further enhanced by a minimum 12mm air gap in the insulated glazing unit commonly found in uPVC windows.
Advances in PVC formulations, including a ‘tropical’ version for extreme heat and UV, have improved resistance to environmental conditions, such as heavy rain, warping, cracking or splitting, making uPVC windows a sound choice for Australian and New Zealand climates. With high resistance to weathering, salt-corrosion and termites, low-maintenance uPVC windows are also an excellent choice for coastal locations.
Today’s uPVC windows not only perform well, they look good, are available in a range of colours and offer superior security, thanks to advances in hardware and locking systems. Commonly used in Europe, the tilt-and-turn opening system provides great versatility for ventilating the house and ease of cleaning from inside the building. For example, in tilt mode, the top of the window tilts forward into the room venting hot air outside while preventing cool air nearer the floor from escaping. The tilt function allows ventilation at night with the peace of mind of security.
Moving the handle into the next position enables the window to be fully opened like a hinge door, allowing for cleaning or additional ventilation. Also available is a tilt-and-slide system with similar sealing properties to the tilt-and-turn versions, but better than the standard sliding windows, which rely on brush seals (which keep bugs out, but not air).
Quality uPVC windows have a lifespan comparable to that of aluminium and are recyclable at end-of-life. With their in-built thermal-efficiency, they are up to 40 per cent more efficient than a standard aluminium window, making them a worthwhile investment in today’s energy-conscious world.
With more window companies offering uPVC windows in Australia amid a growing market, they are becoming an affordable and sustainable fenestration choice for 21st century living.
Working towards Net Zero makes economic, environmental sense

The Vinyl Council of Australia welcomes the findings of a new report that shows stronger energy standards in Australia’s National Construction Code can be delivered cost-effectively for new home owners and will help Australia cut its carbon emissions.
The report, Built to Perform: An Industry Led Pathway to a Zero Carbon Ready Building Code, prepared by the Australian SustainableBuilt Environment Council (ASBEC) and ClimateWorks Australia, analysed and identified measures that would be cost-effective in improving the energy efficiency of buildings relative to the upfront investment cost.
By 2030, improvement in Code energy requirements could deliver between 19 and 25 per cent of the energy savings required to achieve net zero energy in new residential buildings through simple, cost-effective measures such as improved air tightness, double glazed windows, increased insulation, outdoor shading, and more efficient air conditioners, hot water systems and lighting.
Although there are upfront costs associated with these improvements, they are small (less than 4% for detached homes) relative to overall construction costs and land prices while providing ongoing benefit for occupants.
“Australia lags other regions around the world in terms of building energy efficient homes” Vinyl Council Chief Executive, Sophi MacMillan said. “All of the buildings being built today will still be in use in 2050, potentially locking in poor performance at a time when much of the world will be at or near net zero emissions if current target projections are met.”
“We are particularly concerned by the continued use of very low performing windows in a country that loves large windows in its houses. Built to Perform is important in showing there are cost effective measures, such as double glazing, we can – and should – be implementing from today.”
The Vinyl Council also supports the proposition in the report that targets and a forward trajectory are set for future Building Code updates from 2019, with a clear and transparent process for implementation and adjustment over time.
“This approach would provide the certainty industries like ours – supplying thermally efficient uPVC windows and other building products - need to innovate and invest, so as to supply the economic products that higher performing buildings need”, Sophi explained. “This will support a rapid and least-cost, national transition to net zero.”
“Built to Perform clearly shows that cost-effective investment can be made from today to deliver long term improvements in residential energy demand and greenhouse emissions.”
Built to Perform provides industry-based evidence that the Code could, between now and 2050, reduce energy bills by up to $27 billion, cut energy network costs by up to $7 billion and deliver at least 78 million tonnes of cumulative emissions savings.
About the report
Built to Perform: An Industry Led Pathway to a Zero Carbon Ready Building Code presents the results of the Building Code Energy Performance Trajectory project, which quantifies the opportunities of establishing a clear, consistent and ambitious long-term plan for the energy requirements in the National Construction Code. The report modelled eight different building types across four climate zones. It investigated the costs and benefits to society of simple energy efficiency and on-site renewable energy opportunities. The analysis assessed upfront costs associated with improvements, as well as benefits from reduced energy bills, downsizing of heating, cooling and ventilation equipment, and reduced network costs.
This report was produced with the generous support of the Cooperative Research Centre for Low Carbon Living, the RACV and dozens of building industry and government partners. The project has been delivered in partnership with CSIRO, Energy Action (EA), Strategy. Policy. Research. (SPR) and the Sustainable Buildings Research Centre at the University of Wollongong (UOW).
The Vinyl Council of Australia is a member of ASBEC and one of the report’s industry partners.

PVC Recycling in Hospitals program: 150-hospital target in 2018
Written by Super User
The Vinyl Council of Australia aims to expand its successful PVC Recycling in Hospitals program to cover 150 hospitals by the end of 2018.
Since its launch in 2009, the innovative waste management and recycling program has grown to operate in 138 hospitals throughout Australia and New Zealand. It is managed by the Vinyl Council of Australia and its member partners – Baxter Healthcare, Aces Medical Waste and Welvic Australia.
Over the past year, more than 200 tonnes of high-grade PVC waste from hospitals has been diverted from landfill to recycling. This material is redirected to reprocessors in Australia. Australian and New Zealand manufacturers use the recycled polymer in new goods, such as garden hoses and outdoor playground matting.
The program partners are also exploring design of new product applications to accept the growing volume of recyclate generated through the thriving program.
Commenting on their target, Vinyl Council Chief Executive Sophi MacMillan says: “Thanks to great support and enthusiasm from healthcare professionals, the PVC Recycling in Hospitals program is now operating in every state in Australia except the Northern Territory.
“It’s a great example of how the healthcare sector can demonstrate leadership in PVC sustainability and recover high quality material that can be genuinely recycled locally for use in new products. We are currently looking at further end product applications for the recyclate.
“New South Wales is one of our priorities given it only has 11 hospitals participating in the program at the moment. As the state with the biggest population in Australia, the opportunity to grow the program there is really good.”
As part of their drive to encourage greater participation and explain how the program works, Vinyl Council representatives are attending the NSW Nurses and Midwives’ Association Annual Conference in Sydney from 25 to 27 July 2018.
Taking the ‘squiggle’ out of developing recycling solutions
Written by Super User
Fostering innovation in recycling and encouraging circularity of materials in the economy is a challenging and complex endeavour, The Vinyl Council has been engaged in such activity for several years, working with members of the vinyl value chain to facilitate solutions to end-of-life PVC products.
Industry Recycling Strategy Manager, Helen Millicer will be presenting on this topic at the 2018 Waste Strategy Summit to be held in Sydney 26-28 June.
On 28 June, in a presentation entitled 'Pilots and Collaborators – taking the ‘squiggle’ out of developing recycling solutions', Helen will share how the Council works to collaborate widely with stakeholders to develop innovative approaches to waste recovery and recycling. As an example, she will outline the challenges and successes of initiating and managing a project to divert a complex end-of-life vinyl product from landfill and find beneficial uses for the raw materials.
Her talk will cover:
• How to implement concrete and effective recycling solutions in organisations
• Understanding the importance of collaboration between industries, organisations and governments in developing recycling strategy
• Learning how to take maximise the chance of success and take the 'squiggle' out of the process
• Some of the exciting possibilities of PVC recycling in Australia
Helen will then participate in a panel session with a number of experts.
Made locally. Recycled locally. PVC Recycling in Hospitals program leads the way in circular economy
Written by Super User
The Vinyl Council of Australia wishes to clarify some recent reports about its increasingly successful PVC Recycling in Hospitals program.
Managed by the Vinyl Council of Australia and its member partners in the program – Baxter Healthcare, Aces Medical Waste and Welvic Australia – the PVC Recycling in Hospitals program is a local initiative to redirect high-grade PVC waste from hospitals to local recycling companies to be reprocessed in Australia and sold to Australian and New Zealand manufacturers who produce new, finished products such as garden hoses and outdoor playground matting.
Unlike other commercial and residential programs in Australia and New Zealand, the PVC Recycling in Hospitals program processes and recycles PVC material here in Australia, closing the loop on the manufacture, supply and disposal of PVC products in hospitals.
Thanks to the support and enthusiasm of hospitals, nurses and other healthcare professionals in Australia and New Zealand, the PVC Recycling in Hospitals program has now grown to more than 130 hospitals.
Over the past 12 months almost 200 tonnes of PVC waste from hospitals has been diverted from landfill to recycling.
At a time when residential recycling programs are under enormous pressure due to significant changes to waste management policies in China and its decision to restrict the importation of unsorted waste from other countries, the Vinyl Council confirms its PVC Recycling in Hospitals program remains unaffected by these changes in international waste management. We are proud that our industry program continues to lead by example as a local, innovative waste management and recycling program.
To support the growth of the PVC Recycling in Hospitals program, Welvic made a significant investment in modern recycling equipment last year and has created six new jobs at its Victorian PVC compounding plant.
Baxter Healthcare, a local manufacturer of hospital IV fluids bags, has also invested in education and training in the healthcare sector and provides logistics support.
"We seek to assure the healthcare sector and its staff that the PVC Recycling in Hospitals program is strong and is not affected by China’s ban on unsorted materials. All the medical waste collected under the program has always been, and continues to be, reprocessed and used here or in New Zealand," said Vinyl Council's CEO Sophi MacMillan.
"This example-setting program is growing precisely because it is supported by the local vinyl manufacturing industry and the healthcare sector as product consumers. It is a clear demonstration that circularity within Australia can work."
The Vinyl Council is calling on other industries and manufacturers to support the program and for measures to strengthen the local recycling industry.
"We would like to see greater support and incentives from government to encourage local design and manufacturing of products that use recyclate, to drive demand for recyclate use in Australia,” said Sophi.
“And we’d like policies to encourage procurement of those products that demonstrate they are closing the circularity gap in Australia.”
Innovation and sustainability progress unveiled at PVC AUS 2018
Written by Super User
Advances in technology, sustainability and product stewardship over the last 20 years have helped to transform the PVC sector across Australia and turn vinyl into a ‘sound choice of material’, delegates learnt at PVC AUS 2018: Shaping the Future.
Organised by the Vinyl Council of Australia in its 20th anniversary year, the two-day Sydney event in March shared latest developments in PVC formulations and best practice manufacturing that demonstrate the sector’s commitment to continuous improvement.
The event was supported by headline sponsors Austria-based Greiner Extrusion GmbH, Krauss-Maffei Berstorff from Munich, Germany and Italian machinery manufacturer PlasMec.
Vinyl Council Chief Executive Sophi Macmillan commented: “We are driving continuous improvement through the industry in Australia, for both locally-made and imported products, and this is driving change through PVC product supply chains.
“One of the longest standing product stewardship programs in Australia, our PVC Stewardship Program is leading in many areas. These include its life cycle approach, specific and measurable commitments, transparency, and focus on continuous improvement across the value chain.”
Currently 47 companies are Signatories to the Program, representing the majority of the Australian PVC industry. These companies include manufacturers of PVC resin, additives and end-products, PVC compounders and product importers. Major PVC applications represented in the Program include companies manufacturing or importing packaging, cables, windows, flooring, pipes, formwork, medical products, and profiles.
Among the industry successes Sophi highlighted were: a 99.45% reduction in lead additive use since 2002, the Signatories’ 90% compliance with the PVC Industry Energy and Greenhouse Gas Emissions Charter and several PVC recycling initiatives covering advertising banners, commercial vinyl flooring and medical devices.
In his US perspective on ‘Vinyl for a Purpose-Driven Sustainable Development’, Cristian Barcan, VP Sustainability & Industry Affairs at the Vinyl Institute covered key sustainability progress. This includes a 90% reduction in VCM emissions since 1983 and the elimination of lead and cadmium stabilisers. More than 450,000 tonnes of PVC are recycled annually in the US.
Cristian observed: “Unprecedented challenges lie ahead, we have to change. We don’t have three planets of natural resources; doing more with less is needed to address the needs of the next generation.”
Dr Tracy Wakefield of Plustec Pty Ltd outlined the benefits of uPVC Tilt n Turn windows and how their functionality, in terms of low-maintenance, ease-of-cleaning, security and superior ventilation are the future of windows in Australia – and crucially, suit its climate.
With 85% of windows installed in Australian homes still single-glazed, Gerhard Hoffmann of Greiner Extrusion emphasised how the insect-proof, thermally-efficient, 100% recyclable and corrosion-resistant properties of uPVC windows represent a cost-effective fenestration opportunity.
Advances in formulations were a key topic with Dane Tallen of stabiliser manufacturers Baerlocher exploring how calcium-based solutions could provide cost-effective and sustainable solutions for injection-moulding applications; while Dexter Chan from Arkema discussed the improved performance merits of acrylic impact modifiers in replacing chlorinated polyethylene (CPE) in rigid PVC.
Several updates on technology developments in the Australian PVC sector included a new chemical technology to separate PVC and laminated materials. Dennis Collins from PVC Separation explained how their two-stage chemical and environmentally-friendly process works for a variety of materials recycling, from PVC construction products to shoes, medical and food packaging items.
Dario Soncin of PlasMec covered latest developments in PVC dry blend preparation that can contribute to energy savings. Following him, Christian Birzer of Krauss-Maffei Berstorff revealed interesting advances in plastic processing machinery, including increasing the speed limit for pipe, increasing the production density and flexibility of pelletizing and narrowing the limits for u-PVC sheet extrusion.
Arjen Sevenster, Technical and Environmental Affairs Senior Manager at the European Council of Vinyl Manufacturers (ECVM) highlighted major sustainability progress in the European PVC industry and how the VinylPlus Voluntary Commitment is supporting the Circular Economy objectives for PVC.
Summing up, Sophi concluded: “With a high calibre of speakers and content, our conference attracted nearly 150 people and has been a huge success. It has demonstrated that PVC, as a durable, low-carbon plastic with the potential for circularity, can contribute to shaping a more sustainable future for all.”
