If you're researching energy-efficient double glazing in Thornbury you're already in the right catchment — the BS35 postcode is on our daily route from Bedwas. Knowing Thornbury street by street pays off at survey stage. Thornbury is a market town north of Bristol with a mix of historic properties and modern estates. Quality window and door installations serve both traditional and contemporary homes. On a double-glazing upgrade here we typically specify multi-chambered uPVC frames with argon-filled low-E glass, which noticeably warmer rooms by the second winter and quieter living space year-round. All units carry a U-value of 1.2 W/m²K or better and are FENSA-registered on completion. Most weeks we'll have at least one job on the go in Yate or Bristol, which keeps our local response time tight. No subcontractors, no commission-only sales reps — survey by an employed surveyor and install by our own fitters. We beat any like-for-like quote and provide a free no-obligation written survey.

Sash windows are a defining feature of Georgian, Victorian and Edwardian properties. Our modern uPVC and timber-effect sash windows replicate the classic sliding design while delivering the energy efficiency, security and low maintenance of modern glazing.
