Summary

Although timber is combustible – it ignites and flames spread over the surface – the build-up of charcoal on the surface limits the oxygen supply to the underlying timber and acts as an insulator. Therefore, in a fire, the timber below the charred layer is relatively cool and retains its structural integrity. Also, timber burns at a known rate related to its density.

Key Information

When timber burns, the layer below the charred layer is relatively cool and retains its structural integrity.

Timber burns at a known rate related to its density.

The biggest advantage of cement bonded particleboards over other wood based panel products is its superior behaviour in fire.

The term “flame retardant” applies to treatments which actively reduce surface spread of flames.
