3.3Timber preservation (natural solid timber)

This chapter gives guidance on meeting the Technical Requirements for the protection of natural solid timber against fungal decay when exposed to damp conditions and against insect attack.


This chapter gives acceptable treatment schedules for the treatment of natural solid timber but does not cover:

  • products such as plywood and wood particle boards
  • the condition before the treatment
  • treatment process techniques, which is the responsibility of the organisation carrying out the operation.
