Why We Recommend uPVC Windows (And Why Builders, Designers & Developers Should Too)

When specifying windows for a high-performance build, you’re often walking a fine line between energy efficiency, cost, and long-term durability. At efficient habitat, we’ve spent years researching and testing window solutions that deliver strong thermal performance without blowing out budgets.

That’s why we confidently recommend uPVC windows — specifically from Net Zero Plus, who partner with Salamander, a global leader in sustainable, high-performance window systems.

If you’re a builder, designer, or developer looking to optimise cost, energy efficiency, and long-term outcomes, uPVC should be on your radar. Here’s why.

🏗️ Designed for Performance – Engineered for Affordability

Salamander’s window systems offer exceptional thermal insulation with Uf values as low as 0.8, helping projects easily meet — or exceed — NatHERS and Passive House benchmarks.

This level of performance allows for more design flexibility when balancing glazing ratios, insulation, and orientation — especially on tight or complex sites.

♻️ Sustainable From the Start

PVC might have a bad reputation, but not all plastics are created equal. Salamander’s windows are manufactured with up to 50% recycled material (and 100% in their GRETA® eco range), using a closed-loop recycling system that ensures PVC is reused safely and efficiently.

They’re proof that performance materials can also support circular construction models — something increasingly important for compliance and ESG-minded developers.

⚡ Low-Embodied Energy = Lower Carbon

PVC is far less energy-intensive to produce than aluminium, which means significantly lower embodied carbon from day one. In 2021 alone, Salamander’s recycling efforts avoided over 2,700 tonnes of CO₂ emissions — equivalent to taking 600+ cars off the road.

🔇 Acoustic & Thermal Gains in One

We often specify double or triple glazing on elevations facing roads or noisy environments. uPVC frames enhance these benefits, offering superior acoustic control compared to aluminium. That makes them an ideal choice for urban infill projects or high-traffic lots — without the need for costly upgrades.

🌊 Clean Manufacturing Backed by Real Action

Unlike many greenwashed claims, Salamander’s operations are genuinely sustainable — powered by hydroelectricity, treating their own wastewater, and continually investing in clean manufacturing tech like solar PV.

🔧 Built to Last, Easy to Maintain

uPVC doesn’t corrode, doesn’t require painting, and handles Australian conditions with ease. That means less maintenance, fewer call-backs, and a product lifecycle that aligns with low-impact building goals.

At efficient habitat, we don’t just talk performance — we engineer it. That’s why we consistently recommend Salamander’s uPVC windows on the projects we consult on. They strike the right balance between cost-effectiveness, sustainability, and thermal performance — without compromising on aesthetics or durability.
