There is much misconception about the ability of wood to perform under harsh conditions. However, the correct choice of product, good design and the help of technology mean that almost any end use can now have a wood based solution.

Natural properties

Wood is such a unique and diverse material that many end use solutions can be found just by the appropriate choice of species. Research has divided commercial timbers into five durability classes, each with a defined life expectancy. The heartwood of species with a rating of Durable or Very Durable can be successfully used in exterior situations without the support of preservative treatments.

Preservatives and finishes

Preservatives are products applied to timber in order to enhance its natural durability. Meanwhile, Finishes are applied to alter the appearance of timber, but in doing so they may or may not extend its life expectancy. As there are many types of products and many methods of application it is important when specifying preservatives and finishes to be clear about how long you expect the timber product to last and how often it will need to be maintained.

Fire

Timber and Wood Based Products help designers to improve the Fire safety of structures in many ways. Wood Based fire doors are a prime example, by helping to contain the problem and giving occupants the opportunity to escape. Other timber elements such as beams or joists will perform in a predicable way during a fire, which means the integrity of a building can be maintained for a known period of time, helping to prevent the loss of life and minimisation of damage.
