Energy Efficiency & Sustainability

Modern glazing isn’t just about clear views—it’s a cost‑saving upgrade for your entire property:

  • Cut energy bills by up to 28 % compared with pre‑2002 double glazing, thanks to low‑emissivity coatings and argon‑filled cavities.

  • Reduce outside noise by 35 dB with acoustic laminated units—perfect for homes near busy roads or flight paths.

  • Shrink your carbon footprint: Each metre of A‑rated glass installed can save up to 42 kg of CO₂ annually.

  • Future‑proof compliance: Our units already meet the tougher U‑values proposed for the 2025 Future Homes Standard.

Ask our surveyor about triple glazing, solar‑control films or self‑cleaning glass if you want the ultimate in performance and low maintenance.
