Windows of the ADPOL SASH system are traditional, vertical sliding windows used in thousands of British houses.

Sash windows have been modified with a number of technical features in order to improve their thermal performance and security, yet manage to retain the traditional British look, allowing for the windows to be used and specified for conservation areas. 

We offer both the traditional counterbalance weights - ADPOL Sash Weight and modern ADPOL Sash Spring Balance : spring-sliding of basic load-bearing ranging between 5,5 and 27kg or an increased one of the load-bearing range between 27 and 50kg.
