FRE Treatment

Despite being classed as a combustible construction material, timber can perform exceptionally well compared with other materials.

It can maintain its strength and integrity in a well designed structure. Large dimension timbers will develop a surface layer of char which will insulate the timber within and retard fire development.

 The surface of timber will readily ignite and spread along it’s surface. With careful treatment this ‘surface spread of flame’ can be slowed through use of modern pressure treated fire retardants. Smoke propagation can also be reduced, which is often even more important in safety critical applications such as public buildings and escape passages.
