Traditional Timber Box Sash Windows

Our timber box sash windows are the same as they were over 100 years ago, but our wooden sash windows have a better design, better protection and better glass. High quality, wooden sash windows should maintain their traditional appearance, though unfortunately some manufacturers have compromised.
