60-year minimum Service Life for wood windows

The Wood Window Alliance (WWA) has produced an eight-minute video showcasing new research by Imperial College London, which demonstrates that windows made to WWA standards have a minimum estimated service life of 60 years - which can be extended to 80 years or more.

The video explains how this results in a lower Whole Life Cost over 60-100 years than comparable PVCu alternatives, as they will not have to be replaced during the life of a building. It also details the advances in manufacturing and design behind the claims; reviews research by Davis Langdon which shows that WWA frames are CO2-negative; and explores how to achieve authentic period detailing without sacrificing the energy-efficiency of modern window technology.

Wood Window Alliance members make many different styles of window, but all are factory-finished and have to meet stringent quality, performance and sustainability criteria, audited by an independent third party. They carry typical warranties of 30 years on the frames and eight years on the paint finish.
