Wood Information Sheets

Wood Information Sheets (WIS) are 4-10 page long comprehensive introductions to timber topics, intended as an authoritative guide to good design for all practitioners. TRADA has over 70 sheets on a broad range of wood topics.


Resources for TRADA Members and Registered Users:

Introducing wood – This WIS give readers a general overview of timber as both a living, biological organism and as a construction material, and explains the terms used when describing timber and their properties.


Timbers – their properties and uses – This WIS sets out the properties and uses of 140 timber species used in the UK. This can be used to help with species selection or to identify species with comparable properties when alternatives are required. Available for a limited time only.


Resources for TRADA Members and Academic Users:


Moisture in timber – This WIS provides basic information for the specifier and user on the facts and importance of the moisture content of wood. It considers drying, shrinkage and movement, including movement values for some common species, and also looks at measuring moisture content, particularly the use of moisture meters.


Specifying British-grown timbers – This WIS summarises the characteristics and the current and potential uses of timber grown in Britain, and contains a detailed set of species data sheets of a number of Britain's timbers including Oak, ash and Douglas fir.


Specifying timber for healthy buildings – This WIS looks at the increasing evidence base that underpins the use of timber in construction, especially in interiors, where people will interact with materials either directly by visual or haptic senses, or indirectly through smell, air quality, humidity buffering and thermal comfort.


Resources for TRADA Members only:


Introduction to wood-based panel products – This WIS is an overview of wood-based panels. It outlines the manufacture and characteristics of the basic types and also indicates some of the speciality products derived from them. 


Specifying timber exposed to weathering – This WIS explains the causes of weathering and its significance to timber performance.


Preservative treatment for timber - a guide to specification – This WIS guides the specifier through the process of deciding whether a preservative treatment is required, where a treatment is required, and choosing a treatment.


Specification and use of wood-based panels in exterior and high humidity situations – This WIS details the considerations which must be made when specifying wood-based panels for exterior use, in particular whether a preservative treatment or protective measure is required to extend service life.


Structural use of hardwoods – This WIS covers a number of topics relating to the structural use of hardwoods including factors that must be considered when specifying the species.



Books Online

The Books Online area lets you view the full texts – including drawings and tables – of selected TRADA publications online at no extra cost.


Resources for TRADA Members and Registered Users:

Timber for marine and fresh water construction – This book covers a variety of different timber species and for which applications they are suitable.


Resources for TRADA Members and Academic Users:

Off-site and industrialised timber construction: Delivering quality and efficiency – This book explains how timber can be used to meet the imperative for high-quality, sustainable and efficient buildings.


Cross-laminated timber: design and performance – This book covers the design and performance of CLT within construction.



Learning Resources

Learning Resources (LRs) are principally designed for lecturers and students of engineering, architecture and the built environment, but are an excellent starting point for all.


All our LRs are available to both TRADA Members and Academic Users (lecturers and students who have registered for free through Academic access).


Resources for TRADA Members and Academic Users:

Module: Timber as a material – This module includes an introduction to timber, the tree, moisture content and durability, wood-based materials, and why it's important to use the correct names when specifying timber.


Module: Construction principles, specification and design – This module covers the principles of design with timber, designing for durability, designing for building performance, and timber cladding.
