Salamander Windows: Why We Choose Salamander for High-Performance Homes

At Net Zero Plus, every decision we make is guided by our commitment to performance, sustainability, and future-focused building practices. That’s why we’re proud to partner with Salamander, a European leader in premium uPVC window technology and one of the few manufacturers walking the talk when it comes to meaningful climate action.

Salamander’s windows aren’t just high-performing — they’re designed with sustainability at their core, from materials and manufacturing to recycling and reuse. Their company-wide mission? To become a climate-neutral business and lead the industry in responsible production, innovation, and environmental stewardship.

More Than Just Sustainability

“For us, sustainability means more than just environmental protection: we use resources responsibly, focus on long-term employee retention and balanced growth.”

– Götz Schmiedeknecht, Co-CEO, Salamander

Salamander’s approach to sustainability spans four pillars: environmental protection, resource conservation, social responsibility, and smart growth. These aren’t empty promises — they’re embedded in everything the company does, from hydroelectric-powered facilities to their closed-loop PVC recycling systems and award-winning carbon reduction initiatives.

Why PVC? Why Now?

In the context of window manufacturing, uPVC (unplasticised polyvinyl chloride) is widely regarded as one of the most sustainable choices available. Compared to timber or aluminium, PVC:

• Requires far less energy to produce and process
• Has one of the longest service lives of any window material
• Offers exceptional insulation values (up to 0.8 Uf)
• Can be recycled up to seven times without losing performance

What makes Salamander’s offering unique is how they’ve refined and optimised every stage of this process. Up to 50% of the PVC they use is already recycled, and their premium Greta® window line uses 100% recycled PVC — turning old windows into new, with zero compromise on quality or performance.

Resource-Efficient Manufacturing

PVC’s low processing temperature (~200°C) means it consumes significantly less primary energy compared to other materials. Salamander builds on this advantage by:

• Investing in modular, material-saving product designs
• Using hydroelectric power to reduce grid reliance
• Implementing on-site sewage treatment and waste systems
• Designing window systems that are easier to disassemble and recycle

In 2021, their main site in Türkheim alone purchased 1,481 tonnes of recycled PVC, preventing an estimated 2,745 tonnes of CO₂ emissions. That’s equivalent to taking hundreds of cars off the road for a year.

A Long-Term, Values-Aligned Partner

Salamander’s environmental leadership goes hand-in-hand with its social and economic values. As a family-owned business with more than 100 years of history, the company takes a holistic view of sustainability that includes:

• Employee wellbeing and education initiatives
• Advocacy for diversity and inclusion, with staff from more than 34 nationalities
• Resilience through thoughtful, sustainable growth
• Collaboration with industry bodies such as Rewindo, EPPA and VinylPlus

This long-term thinking mirrors our own approach at Net Zero Plus. We’re not interested in building faster at the expense of the planet — we’re here to build better, smarter and more sustainably.

Salamander Windows are a perfect fit for our high-performance, low-impact homes and are part of the reason we can offer triple-glazed systems that meet Passive House standards while helping reduce energy use by up to 70%.

The Bottom Line

The windows you choose matter. And when they come from a company actively working toward becoming climate neutral, you know you’re making a decision that supports both people and the planet.
