Wood Window Alliance

The Wood Window Alliance (WWA) promotes and champions the beauty, efficiency, sustainability and durability of wooden windows. Founded and managed by its members, the WWA is the benchmark for industry standards, with members having to meet independently verified quality, performance and sustainability criteria.

Committed to backing up claims with authoritative, independent research, the WWA have engaged in significant life-cycle analysis and performance reviews. Through such studies, it has been demonstrated that wood window frames made to WWA specifications are carbon-negative over their overall life-cycle.
