Timber windows

The appearance of traditional timber casement or sash windows is timeless but the technology and precision tooling used these days by craftsmen ensures that each window is a perfect visual and technological fit. As installers of these superior quality windows we are very much aware that individual styling to suit the property is essential. Timber windows are made to suit all properties whether it is a thatched cottage or a hi-tech modern development, each window is engineered for maximum thermal and acoustic performance.

George Barnsdale windows are supplied to us pre-glazed to British Standards with 24mm Double Glazed units using Low E Energy Saving Glass. Further glass specification may be added to this for improved acoustic performance.
