Why it’s so important to preserve original sash and casement windows in old buildings

Sash windows and casement windows are part of our heritage and have been a common sight on UK properties since the end of the 17th century. Sash and casement windows represent a significant contribution to the charm and characteristics of period buildings and are a feature many property owners are keen to retain.

For private domestic homeowners, these original features are likely to be one of the reasons they chose the property in the first place, along with other visually aesthetic features. With the proper care they will add value if and when the owner comes to sell. From a wider heritage point of view, public buildings with sash and casement windows may be protected by laws that regulate their modification and replacement…
