JG King Homes moves to aluplast uPVC insulated window systems

For nearly 40 years, JG King Homes has been a leader in innovative construction of project homes, offering Victorian families quality homes with unrivalled structural warranties. As a family-owned business, JG King has earned the trust of its customers, delivering a 50-year structural warranty on all homes—an industry-leading assurance of their commitment to quality. As the only volume home builder in Victoria to provide steel frames as standard, JG King differentiates itself with TRUECORE® steel, ensuring strength, durability, and peace of mind for homeowners.

A key to JG King's success is its vertical integration. The company not only manufactures its own steel framing but also operates Project Windows and Doors, a window fabricating business that supplies all of JG King's new home builds, as well as smaller builders and renovators across the region. This control over materials and processes enables JG King to maintain high standards of quality while innovating ahead of industry trends.

After the federal government first proposed increasing the minimum energy efficiency standard for new homes from 6-star to 7-star, JG King Homes responded swiftly. Already committed to sustainability and energy efficiency, the company saw this as an opportunity to enhance their offerings. "We’ve always been ahead of the curve in adopting better building practices," says John King, executive director of JG King Homes. "When the government signalled the shift to a 7-star energy rating, we began testing our materials and designs to meet the new standards well before they became mandatory.

“We have never been scared to take a risk and choose what we believe are better building elements for our homes,” King says.

Realising that double-glazed aluminium windows couldn’t achieve the necessary thermal performance, after extensive research, JG King turned to uPVC. "I looked at what was happening in Europe and the US, where uPVC dominates the market," says King. "Also, the systems, machinery, and processes around uPVC were far more advanced than aluminium. It was a clear decision to move forward with uPVC."

Selecting the right supplier was crucial. "We needed a partner who could meet our high demands for volume, consistency, and quality," King notes. After thorough investigation, they chose aluplast for its quality, performance, capacity to supply, customer service and modern aesthetic. JG King Homes made significant investments in new equipment and technologies, importing state-of-the-art machinery from Italy for uPVC fabrication. They now manufacture the only uPVC windows in Australia with V-Perfect technology which creates a truly seamless weld that maintains a perfect appearance for decades.

"Our factory now operates with a level of automation that’s vastly superior to an aluminium setup. It’s allowed us to produce windows with a seamless weld and a cleaner finish—something our customers really appreciate."

This investment has not only improved the quality of JG King’s window systems but also increased their production capacity. "We can now manufacture double the quantity of windows we need for our own builds," King reveals.

The benefits of aluplast uPVC systems extend beyond energy efficiency. "These windows offer superior thermal insulation, soundproofing, and security," King says.

"They’re also completely recyclable and reusable, which aligns with our commitment to sustainability. aluplast has a closed-loop recycling system, meaning they pick up all our waste and reuse it in other products. It’s a perfect fit for our environmental goals."

Introducing aluplast uPVC systems before Victoria’s 7-star introduction in 2024 has proven to be a game-changer for JG King Homes. "The feedback from our customers has been fantastic," King shares. "People can’t believe how quiet, comfortable, and secure their homes are. It’s a real testament to the quality of the product."

In a rapidly evolving industry, JG King Homes continues to set standards for quality, innovation, and sustainability. Through forward-thinking and strategic partnerships, they are meeting today’s market demands and helping shape the future of Australian homebuilding.
