Fineo is an advanced ultra‑thin vacuum glazing that delivers the thermal performance of triple glazing in a unit just 7.7mm thick. Designed specifically for retrofitting into existing timber frames, it offers exceptional insulation (U‑value 0.7 W/m²K), reduced noise, improved comfort and a lower carbon footprint — all without altering the character of your original windows. As the only vacuum glazing manufactured in Europe and backed by a 20‑year warranty, Fineo provides a modern, high‑performance upgrade for traditional properties.

Fineo glazing performs at its best when installed by joiners who understand the nuances of traditional timber windows. At Coulson Joinery, our heritage in architectural joinery means we treat every frame with care, precision and respect. We retrofit Fineo seamlessly into existing sash frames, preserving your home’s character while delivering modern thermal performance, reduced noise and long‑lasting comfort. When you choose us, you’re choosing craftsmanship, accuracy and a finish that stands the test of time.
