Durability by design
Designers can considerably extend the life of timber components by attention to detail. Achieving ‘durability by design’ requires the designer to understand the performance requirement for the component.
In order to define performance, designers must:
- Identify an appropriate service life for the structure and components, taking into account the acceptable maintenance and possible replacement of parts
- Understand the hazards likely to be encountered during the life of the component or structure
- Understand the capability of materials exposed to such hazards to meet these expectations.
The performance can then be matched to appropriate specifications and protective design detailing.
This Wood Information Sheet (WIS) focuses on timber's resistance to weathering, adverse atmospheric conditions and fungal and insect attack.
Fire also threatens the 'durability' of a structure. However, specifying for fire resistance is covered in WIS 4-11: Wood-based panel products and timber in fire.
- Expected service life and component sensitivity
- Hazards and material behaviour
- Principles for protective detailing
This Wood Information Sheet was reviewed in March 2019 and minor corrections were made.
Wood Information Sheet 2/3-63: Modified wood products is due for its third revision in five years. This high frequency of revision reflects the increasing range modified woods coming to market and the need to make specifiers aware of their properties and suitability for different end uses.
This document contains a fully comprehensive list of all the most up to date Wood Information Sheets (WIS) published by TRADA. Available to members for free or non-members for £12.00, these Wood Information Sheets provide technical guidance related to almost every timber topic under the sun.

The first decision to be made regarding preservative treatment is whether the use of a naturally durable species will satisfy the durability requirements or whether treatment is needed. This Wood Information Sheet aims to guide the specifier through the process necessary to reach a decision that will result in a...
