The Wood Window Alliance (WWA) promotional organisation has released a film highlighting its products’ service-life performance and carbon footprint superiority over rival materials.

The eight-minute film, aimed at architects and other specifiers, is called Wood Windows C02t Less and is based on service life research by Imperial College.

Its theme is that wood windows last longer and are better value than PVCu products, as well as having a lower carbon footprint.

The commentary claims that three-quarters of a tonne of CO2 can be saved by fitting a standard house with timber windows rather than PVCu – the equivalent, it says, of the volume emitted by a small family car travelling 6,500km.

The film also highlights the ability of modern manufacturers to “repair, replicate or replace” old timber windows to ensure refurbished or new products are in keeping with historic buildings, plus how these products can combine authentic looks with up-to-date energy performance.

“The film is all about offering architects and specifiers the information they need to make an informed decision when specifying windows,” said WWA chairman Sean Parnaby.
