Our Materials

Sustainable. High-Performance. Built to Last.

We exclusively use FSC-certified timber, ensuring that every piece of wood we work with comes from responsibly managed forests. Our preferred choice for most windows is Accoya High Performance Modified Wood—a revolutionary material that’s carbon-negative and built to last.

  • 50-Year Guarantee – Accoya’s stability and durability are so exceptional that its manufacturer offers an industry-leading warranty.

  • Outstanding Weather Resistance – Unlike traditional timber, Accoya is highly resistant to swelling, shrinking, and rot.

  • Sustainable & Carbon Negative – Made from fast-growing, sustainably sourced wood, Accoya actively reduces carbon emissions over its lifetime.

Our windows are designed to meet and exceed modern thermal performance standards, ensuring that homes stay warmer for longer while reducing energy consumption.

Our Timber

We work closely with a local glass supplier who specialises in narrow double glazing—a cost-effective solution for heritage windows that need to meet conservation requirements without compromising on insulation. For more modern builds, we also source larger double-glazed units (up to 24mm thick) that deliver excellent thermal and acoustic performance.

For those looking for the very latest in glazing technology, we also offer Fineo and LandVac vacuum glass. While not locally sourced, these innovative glass options provide exceptional U-values in a slimline unit, making them perfect for heritage projects that need modern insulation without altering traditional aesthetics.

  • Narrow Double Glazing – Our local supplier specialises in slimline heritage glass, ideal for traditional windows without compromising insulation.

  • Fineo & LandVac Glass – Cutting-edge vacuum-sealed glazing that delivers a superior U-value in an ultra-thin profile, making it perfect for historic and high-end projects.

  • Exceptional Thermal & Sound Insulation – Achieve modern performance without altering the original character of a property.

These glazing technologies ensure that our heritage windows meet conservation standards while delivering superior energy efficiency—proving that tradition and innovation can go hand in hand.

Our Glass

Minimising Waste, Maximising Efficiency.

Sustainability doesn’t stop with sourcing—it’s embedded in how we work. We reuse and recycle wherever possible, ensuring minimal waste and maximum efficiency.

  • Offcuts are repurposed to heat our joinery yard, reducing energy use.

  • New dust extraction system keeps our workshop clean and safe for staff.

  • Reduced CO₂ footprint through efficient material use and waste management.

This not only reduces our environmental impact but also allows us to offer exceptional value to our customers, without compromising on quality.

Built For The Future

Every material we use is chosen for its performance, sustainability, and longevity. Whether it’s Accoya timber, vacuum glazing, or our commitment to minimising waste, we ensure that every window and door is an investment in quality craftsmanship and a greener future.
