In today’s rapidly evolving property sector, the sustainability and durability of building products are paramount. As the construction industry grapples with environmental challenges, material selection plays a crucial role in shaping the future.

One material that stands out for its durability, versatility and resilience in meeting both environmental and economic needs is PVC.

Unlike other forms of plastic, 57% of PVC’s composition is derived from salt, an abundant natural resource. Exceptional durability is one of PVC’s most compelling attributes. With exceptional resistance to corrosion, weathering, and environmental degradation, products made from PVC can remain in use for generations. In construction, this means longer-lasting materials that require minimal maintenance, ultimately leading to cost savings for property developers and owners.

PVC’s versatility is another key factor driving its widespread use in construction. It can be easily extruded into various shapes and forms, making it suitable for a wide range of applications. From pipes and window frames to flooring and roofing materials, PVC’s adaptability allows it to meet the diverse needs of the property sector.

Reliability is a critical consideration in construction, and PVC delivers on this front. Its inert nature ensures that it remains safe for human use, in water infrastructure, and the environment. With a proven track record spanning multiple decades, PVC has demonstrated its reliability in applications where human health and wellbeing are paramount.

 

PVC applications in construction

PVC’s remarkable properties make it an ideal choice for numerous construction applications. Here are some key areas where PVC is widely used in both Australia and globally and making a significant impact.

 

Pipes, plumbing and ducting

PVC pipes are widely used in plumbing and water infrastructure systems due to their durability, resistance to corrosion and chemical degradation, and ease of installation. They provide a durable and reliable solution for transporting water, wastewater, and gas, ensuring the longevity and efficiency of pipeline infrastructure.

In Europe, underground PVC-U and PVC-Hi pressure pipe systems for water and natural gas supply have been shown to have an expected service life of at least 100 years, according to a joint position paper by PVC4Pipes and TEPPFA. Being highly durable and able to be recycled multiple times without losing their long-term mechanical performances, PVC pipes are a cost-efficient, safe and sustainable choice for transporting drinking water and natural gas, through the whole life-cycle of the distribution networks.

The Vinyl Council of Australia added a new category – PVC Duct Systems – to its Best Environmental Practice PVC Product Register in response to the growth in the use of low-profile PVC ductwork systems.

The EcoDuct 300 Series is the first product in this category to carry the Vinyl Council’s Best Environmental Practice (BEP) PVC trademark. This mark is awarded to independently assessed, Best Practice PVC-compliant products that meet stringent life cycle criteria, developed by the Green Building Council of Australia.

Incorporating up to 50% recycled PVC, the newly accredited EcoDuct is a low impact, fire retardant duct system that is specifically designed for high-rise apartment applications where limited ceiling spaces are common. It is also 100% recyclable at the end of life.

The Vinyl Council’s BEP PVC Register covers a wide range of BEP-accredited construction products. PVC Duct Systems join existing categories covering flooring, resilient wall coverings, pipes & fittings, conduit/fittings, fencing, cable and permanent formwork.

 

Windows and Doors

PVC window and door frames are favoured for their thermal efficiency, sound insulation, and low maintenance requirements. These frames contribute to energy savings by enhancing insulation, reducing heating and cooling costs for buildings.

High-performance windows are essential for achieving 7-star home standards, enhancing energy efficiency, and maximising occupant comfort. uPVC (unplasticized polyvinyl chloride) stands out as the superior choice due to its insulation, durability, sustainability, and cost-effectiveness, outperforming aluminium, and timber in key areas.

Flooring 

PVC flooring offers a cost-effective and resilient option for residential and commercial properties. Its water resistance, ease of cleaning, and wide range of design options make it a popular choice for both high-traffic areas and aesthetic appeal.

 

Roofing

PVC roofing membranes are known for their durability and weather resistance. They provide excellent protection against harsh environmental conditions, extending the lifespan of roofing systems and reducing the need for frequent replacements.

 

Recycling PVC: A Sustainable Approach

As sustainability takes centre stage, the construction and property sector must focus on recycling materials to reduce waste and conserve resources. PVC excels in this regard, as it can be recycled into new, long-lasting products without compromising quality and integrity.

 

The recycling process

PVC recycling involves collecting, sorting, and processing used PVC products to produce recycled PVC, often referred to as “rPVC.” The recycling process includes:

  • Collection: Gathering used PVC products from various sources, including construction sites, hospitals, and households.
  • Sorting: Separating PVC materials from other types of plastics to ensure a pure recycling stream.
  • Processing: Shredding, cleaning, and melting the collected PVC to form new products.

Recycled PVC can be used to manufacture new, long-lasting construction materials, from pipes, ducting and window frames to flooring and roofing membranes. This not only conserves resources but also reduces the demand for virgin PVC, lowering carbon emissions associated with production and contributing to a circular economy.

The VCA’s PVC Stewardship Program (PSP) addresses specific, measurable commitments across the lifecycle of PVC, including raw materials, manufacturing, supply chains, additives, waste, and recycling. The program aims to further the safety and sustainability of the PVC industry in Australia. There are 44 reporting Signatories committed to furthering the safety and sustainability of the PVC industry in Australia.

In 2024, Signatory use of locally sourced rPVC declined by 7% to 2,090,831kg. Yet, on a positive note, of the 19 PSP commitments scored in 2023 and 2024, compliance has improved in all but two (use of recycled PVC and safe handling of recycled PVC). Average compliance (pre-Auditor assurance) has increased from 86% to 91%. This is a doubly pleasing result because two new commitments are scored for the first time in 2024.

As the Vinyl Council of Australia continues to work diligently with partners across the PVC sector, it is clear that now more than ever before, using durable, sustainable, and cost-effective PVC products makes sense. Build a better world with PVC, and together, we can pave the way for a greener and more sustainable future in the Australian construction and property sectors.
