More susceptible to wooden houses for fire

Before starting the study of the issue of more or smaller exposure to wooden buildings to fire, it is necessary to understand for yourself that everything burns, absolutely everything, only at different temperatures. Multi -storey panel buildings, brick houses for personal residence of one family are burning, absolutely all the material burns, even iron trams burn. But not every material can light up from the closure in the mains or under the long effect of the flame.

In the same way, not every material spreads the flame, some materials have a class of non -combustibility «NG», that is, they do not distribute open flame, some «G4», This means that in four seconds, under the influence of a flame, the material lights up and spreads the flame. Such a thing as burning in regulatory documents is not found anywhere.

For residential buildings or technical products, such an indicator as a class of fire resistance or refractory is used. Wooden houses made of whole beams or with the frame structure of the walls have very high resistance to fire. The most vulnerable parts of the house made of wood are roof, especially if it is made of wood chips (gont).
