The weight of a wooden houses is on average 3-4 times lower than a traditional concrete-brick construction, resulting in lower seismic strength and greater resistance to earthquakes and the natural elasticity of the wood ensures a good behavior of the house.
Yes, the wood burns and no one contests this statement but it burns at a speed of 0.70mm/minute, and after 30 minutes of burning, the ash deposited on it does not let the fire spread further. The formed ashes protect the rest of the wood from fire propagation. Generally, the fire affects all construction materials in different ways, even if a certain structure does not burn, it has always a reaction: steel loses half of its strength and becomes yielding at 800 Celsius degrees, the concrete cracks and peels and so on with all the material we look at, each one reacts to fire in its own way. For the wooden houses, there are woodfire protection treatments that increase the resistance and controls the fire behaviour by delaying the burning rate of the wood.
In the old wooden houses, the wooden boards «whistle» which causes noise problems since the wooden elements are placed one above the other and kept together by nails. Creaks are given by rubbing two pieces of wood together.
If we use better gripping, or if we use certain soundproofing materials such as felt, rubber or other specific materials, we eliminate the squeaking in the house.If we lay 5-6 cm of sound-absorbing material (such as rigid wood, mineral wool, cork, etc.) on the floor, we have ensured the necessary sound insulation of it, both for background and impact noise.
Wood cracks occur during the natural wood drying process and variations in humidity over time. The most prominent cracks are in beams that still have the heart of the tree in the section. Many of the cracks do not affect the resistance of the wood, which stabilizes over time. In our days wood is dried in industrial dryers before the final processing, which limits cracks in time, and if we use laminated wood the internal stresses compensate each other and the cracks are small and very limited.
Wood rot occurs when is exposed to moisture and humidity variations constantly or if the timber is in contact with the topsoil or organic matter, which speeds up its reintegration in nature. The use of waterproof membranes, foundation and other waterproof materials are the best rotting prevention solutions for the timber houses.
The mushrooms appear on the wooden constructions if the wood we use is still green and wet, or it is in contact with water or wetlands most of the time. Dry wood (>15% moisture) does not have such problems. To avoid the formation of mushrooms after building the house, the wood must be dry and a specific treatments or protections can be applied to ensure the best resistance in time.
