Wood has been an excellent natural building material in history. In some countries like Finland, wood has always seen as the main building material as its popularity of the tradition of wood house since centuries ago. This country even made significant investments in the development and research of timber construction. The purpose of these efforts has been to increase the use of wood in construction.

There is a proof that wood known as building construction by the existence of old European wood house made in the 16 century. It is also proven that wood performs better toward fire risk compared to steel or brick. Many wood house manufacturers apply fire rated materials like plasterboard or charcoal to cover the timber frame in order to added protection to it.

Charcoal is crystallized pyrolysis on the outside surface which in itself acts as an excellent heat insulating material. It is a secret made by most construction manufacturers when the decomposition wood happens to the temperature around 271 degrees Celsius. Wood does not char until a high temperature is reached and does not conduct heat well that makes this reaction is slow to penetrate into the interior of the wood beam.

Modern wood or timber frame construction uses technological advances for improving the performance of wood. It is done without changing the benefits of the raw material. It surely experienced to retain the product quality.
