Resistance to Fire
In wooden buildings, members’ building layers are based on fire resistance and the requirements of building material standards (fireproof or fireproof). The walls of the loader, which have a double layer of gypsum panels or wooden products, are used in the space between the two layers of insulating materials that are fire-proof and provide the conditions for high resistance.
Modern wood construction is best suited to the issue of fire protection. The technological progress and the total positive experience with wooden buildings have been considered by the legislator, and the construction of wooden buildings for up to five floors provides confidence to the wooden structure.
In this building system, all wooden structures are covered with refractory materials. In most cases, gypsum boards are used as fire protection layers, so that in most wooden buildings, all internal surfaces of walls and ceilings are covered with gypsum boards.
The plaster, due to 21% water crystallization, has a high fire resistance and is widely used as a heat insulation material to protect columns and components of wooden buildings during fire.
It is true that the wood is flammable, but the coal produced on the surface of the wood, due to its thermal insulation, reduces the penetration rate of fire inside the wood, resulting in greater stability. Due to this phenomenon, solid wood beams in fires have shown much more resistance than steel.
