The company, which has also launched a new technical guide for its wood windows, says demand is being driven by housing associations and housebuilders, who recognise the environmental benefits of timber.

All of JELD-WEN‘s softwood timber windows are PEFC chain of custody certified, which means they can be tracked back to the forest to ensure they originate from a well-managed sustainable source.

And, while green credentials are essential, the company believes factory finishing is equally playing a role in helping support the resurgence of timber.

“Choosing sustainable products goes hand in hand with selecting those that are energy efficient,” said Tony Pell, product manager at JELD-WEN. “All our factory glazed timber windows are fitted with Low E glazing units, which enable them to achieve some of the best U-values on the market, as well as helping to meet Part L requirements.”

JELD-WEN offers a six-year guarantee on Hi-build factory stained or a 10-year guarantee on Hi-build factory painted windows, which it says reduces labour requirements on site.

“Our aim is to promote good practice within the window industry and show that timber is the natural choice for energy efficiency, low maintenance and enhanced security,” said Tony Pell.

The new guide provides practical information on the correct method of installation for different types of timber window, as well as care and maintenance on site.

“This guide is designed to promote good practice, as well as making it as easy as possible for customers to choose the correct windows to meet their requirements,” added Mr Pell.
