Refractoriness of a wood-frame house
isn´t less than refractoriness of a traditional construction.
If it wasn´t true the wood-frame technology wouldn´t
be so commonly used in developing countries. No doubt that wood
is a good fire conductor but before the fire is able to reach
a wood structure has to pass through outside surfaces such as
Pladur panels, siding or fire-brick. Furthermore OSB panels
(Oriented Strand Board ) with the help of special treatments
attain a high level of refractoriness.
