Timber Window Accreditation Scheme and the BSI Kitemark
In July 2004, the British Woodworking Federation (BWF) formed a partnership between its Timber Window Accreditation Scheme and the BSI Kitemark scheme.
To mark this significant development, the BWF changed the name of its scheme to the TWA scheme.
At the heart of this partnership is the requirement that all TWA scheme manufacturers will have to gain BSI Kitemark certification (BS 644) for their factory glazed timber windows. In addition to the technical criteria the Kitemark requires TWA Scheme manufacturers to undergo:
- Independent and third party auditing of their products
- Compliance with the TWA Scheme quality control requirements
- Stringent operational and weathertightness tests for each window style
- An annual audit test of a random window sample
- Two rigorous factory inspections per year to ensure compliance with the technical criteria.
