Batten Information

BS5534 Battens are manufactured from timber selected from approved sources in accordance with BS 5534:2014 + A2:2018 and graded by an optical grading machine prior to the application of a preservative treatment Tanalith to BS 8417:2011.

Fully graded BS 5534 battens are becoming a standard warranty requirement with these guaranteed schemes:

  • National House Builders Council (NHBC)
  • Local Authority Building Control (LABC)
  • Roof Sure • Roof Sure Plus
  • NFRC Co-partnership
  • Trustmark
  • Competent Roofer

Since October 2011, NHBC Standards require that all timber used for battens and counter battens should be indelibly marked with the appropriate markings of BS 5534.

How to tell if battens are fully compliant with BS 5534

Each batten that fully complies should be indelibly marked with the following information:

  • supplier
  • ‘Graded BS 5534’
  • size
  • if applicable, the third-party certification scheme logo
  • origin (imported or British grown, and/or species code WPPA or Other as below– see table).

Battens that are produced under independent third-party schemes such as the BM TRADA Certification Q-Mark Timber Tiling Batten Scheme and BRE’s ‘Tickmark’ Scheme are now appearing on the market and some are colour coded to depict graded material.
