Many readers write to us because they have well understood the advantages of wooden houses than those built with traditional construction called, or cement and bricks. In other countries, such as here in Australia where we are writing, the wooden buildings represent a substantial part of housing, and even individual homes built with brick facades, a type of popular building especially in the suburbs and countryside , they have a wooden frame and wooden walls, with only the outer shell of bricks.

Let's analyze point by point the advantages of wooden houses, as many in Italy still have doubts about several aspects of this type of construction. We begin by stating that a wooden house normally provides a healthier environment for occupants, with a strong reduction of mold and bacteria inside the home, especially with important benefits for allergy sufferers. The hygroscopic properties of wood make that can actually adjust the amount of moisture in the air inside the house.

Wood is a natural material that builds up heat and moisture from the surrounding air, regulating the climate inside the house and reduce overheating in summer. This is due to the low thermal conductivity of wood, and simplicity in building structures with few thermal bridges.

Obviously a major feature of wooden houses is that it is a building material which does not affect the ecological balance. The whole process of production and woodworking procude few CO2 emissions, much less other pollutants. The energy needed to produce the necessary wood to build a house comes to be a small fraction of that required for a house brick. The tailings can also be easily recycled or reused, maybe even only as fuel for a chimney or boiler.

That brings us to the economic aspects: a wooden house can be prefabricated or built largely at the factory and then assembled on site. This system optimizes the cost and reduce construction time (other factors affecting costs), also eliminating the variable weather that affects profoundly in the case of a construction site entirely. Reduced construction time mean less interest payable for any loan, payable monthly and possibly less if you live in a rented house.

The last point is related to the durability of wooden houses, and the amount of maintenance required. In countries like Australia there are whole villages in the late nineteenth century with houses built entirely of wood, and certainly not with the techniques and modern materials, which are still in perfect condition and regularly habitable. The rest of the wood raw material is more resistant to aggression of atmospheric agents, even in extreme climatic conditions as reflected in the wood construction found in geographical areas with completely different climate, as cold and hot Australia Canada.
