Up next on Fundamentals of timber: Moisture in timber

TRADA image

Learn with TRADA Live: Fundamentals of timber provides a comprehensive overview of the many aspects of timber and is intended as an introductory resource for newcomers to the material and those looking to construct a strong foundational layer of knowledge upon which to build with the support of a trusted authority like TRADA.


The final two webinars of the 'Fundamentals of timber' series cover moisture in timber. Since it is an important subject and the webinars are best attended in sequence, attendees can only register for both webinars as a bundle.


Moisture in timber – Part 1 (2 Nov 2021, 12:00–13:00 GMT)

This covers: the most important timber issue to understand; what green timber or seasoned timber is; understanding the amount of water in timber; Equilibrium Moisture Content (EMC) and Fibre Saturation Point (FSP); what 12% moisture content means; why and how the moisture content of timber changes; drying of timber and good methods of storing timber; and shrinkage and movement.


This webinar has now taken place. However, you can still book on to attend Moisture in timber – Part 2.


Moisture in timber – Part 2 (14 Dec 2021, 12:00–13:00 GMT)

This covers: how much timber can shrink and how this occurs; shrinkage and swelling in the different planes of timber; movement classifications and how this aids determining the amount of shrinkage; how we accommodate shrinkage and swelling; and an introduction to Use Classes and in-service moisture contents.



Part 1 has now taken place. However, you can still book on to attend Moisture in timber – Part 2. The prices below reflect this.
