Background | Why the WWA?

The Wood Window Alliance was formed in 2007 by a group of leading manufacturers supplying timber-based windows and doors in the UK and Ireland to:

As a condition of membership, manufacturers must meet independently verified quality, performance, and sustainability criteria. Membership and performance auditing are reviewed annually.

Windows are: fully factory finished and glazed; CE marked, supported by Declarations of Performance; supported by warranties covering glazing, ironmongery, and coatings endorsed by accredited WWA suppliers; and fitted by qualified installers. Through testing and certification, members can provide reassurance, where necessary, that windows and doors are tested to PAS24 in compliance with Approved Document Q. Many members also have the prestigious Secured by Design accreditation.

Members supply (and often install) new and replacement timber, modified timber and alu-clad timber windows and doors for modern and period domestic properties.

The Alliance is committed to backing its claims with authoritative, independent research and to promoting informed debate on issues such as service life, sustainability, and cost value comparisons.

The Wood Window Alliance is part of the British Woodworking Federation.
