What are sliding sash windows?

Sliding sash windows were a common site in Georgian and Victorian homes and consist of a movable pane which allows you to control ventilation in your home. Available in both uPVC and timber, our sliding sash windows allow you to retain the original character of your home while improving its efficiency and comfort. They offer effortless operation with the use of tensioned balances; either sash can also be tilted inwards to allow for easier cleaning. Spring balances are concealed within the framework for easy adjustment and eliminating the need for cords. With traditional features such as an oval shaped frame and classic sash horns, the authenticity is retained giving you a beautiful window that will complement your home.

This also prevents children operating the windows and they offer superb security against possible intruders.
