Timber windows have a proven life cycle of 100 years; it is unlikely that Aluminium or U.P.V.C could match this, as they are difficult to repair and apply new protective coatings, which usually results in the whole window or door being replaced.

Windows and doors manufactured in timber have a huge advantage environmentally over alternative materials commonly in use. This can be measured by the embodied energy used, the embodied energy measures the total energy used to transform raw material into ready to use building products. It is expressed in megajoules per kilogram (Mj/kg). The direct effect of the amount of energy being used to convert the raw material into a usable product reflects in the amount of carbon released into the atmosphere. If you also consider the amount of carbon dioxide being stored during the manufacture of timber the benefits of timber become considerable.
