The TDUK Market Briefing is a comprehensive new resource from TDUK to help stakeholders from across the timber sector better understand the timber market and current economic conditions.

Timber Topics August 2025 | Timber Use Classes

by Jennie Ward|29 July 2524 September 25|Build, Supply

Do you know your Use Classes? The way treated timber must be described in merchants and on site has changed. It’s up to you to understand what Use Class the treated timber products you stock have been treated to, and where it is safe for them to be used. TDUK...

Timber Topics July 2025 | Understanding external timber cladding

by Jennie Ward|27 June 2524 September 25|Build, Supply

To support best practice across the industry, TDUK – working in collaboration with the Timber Decking & Cladding Association (TDCA) – has created the Timber Cladding Handbook, a valuable resource available at www.timberdevelopment.uk.

Designing for Natural Durability

by Guest Author|08 June 2531 March 26|Design

The case studies in this publication demonstrate longevity and durability of untreated timber used in external instances. They show that timber can provide robust results with an unparalleled aesthetic free from chemical treatments.

Shear and Torsion

by Edinburgh Napier University|13 November 2423 April 25|Design

Eurocode 5 provides verifications for design for shear, for stress components (both parallel and perpendicular to the grain), as well as advice on design for torsion, based on shear strength of the section.

Lateral Torsional Buckling

by Edinburgh Napier University|13 November 2423 April 25|Design

Lateral torsional instability may arise in timber members subjected to either bending, or bending and compression forces.

Creep

by Edinburgh Napier University|13 November 2423 April 25|Design

Over time, both the elastic deflection of loaded timber members and the relative movement of timber members mechanically fastened together increase. This time-dependent increase in deformation is called “creep.”

Airtightness

by Edinburgh Napier University|13 November 2423 April 25|Design

Achieving airtightness in a timber structure design is vital for energy efficiency, thermal comfort, and to protect a timber structure from dampness and mould.

Strength Grading

by Edinburgh Napier University|08 November 2430 April 26|Design

Due to the significant variability of characteristics across different woods, a strength grading system exists to classify timber that is safe and effective for use in structural applications.
