Timber sash windows are traditional vertically sliding windows made from wood, typically featuring two counterbalanced sashes that glide within a box frame.
Prized for their craftsmanship, aesthetic warmth, and repairability, they are a defining feature of UK period properties-from Georgian elegance to Edwardian simplicity.
When properly maintained and restored with breathable finishes, timber sash windows offer exceptional longevity, authenticity, and-when upgraded with heritage-appropriate double glazing-modern thermal and acoustic performance.
