Inwido UK is the latest member to join the Wood Window Alliance (WWA).

The company, part of the Inwido Group, a leading Nordic window and door manufacturer, has a product portfolio which includes an energy efficient, triple-glazed window offering a U-value of 0.8.

“The more members we have, the more powerful the campaign and the more we can do to promote wood windows as the choice for the 21st century,” said WWA campaign chairman Nick Quinn.

“The value of membership was really demonstrated at Ecobuild when the WWA stand generated great publicity and numerous sales leads for members.”

As part of the WWA, Inwido will benefit from using the Alliance’s distinctive heart and tree brandmark.

To carry the WWA brandmark Inwido’s windows must be manufactured from sustainable wood sources, be accredited by an independent UK or European body and have warranties for durability, paint life, ironmongery and insulated glass units.
