From an architectural point of view, prefabricated wooden houses can offer the same characteristics of living comfort as modern brick buildings. Just follow the necessary precautions.

The construction of prefabricated wooden houses must follow certain architectural rules capable of guaranteeing the right structural stability and durability.
In some ways, the construction procedure for these buildings is different from that required to construct brick houses. While the finishes and attention to the best possible insulation must follow the same precautions required by the legislation in force in terms of limiting consumption.

The wooden structure offers the same performance as the traditional one.

There is still today a serious prejudice towards prefabricated wooden houses. It is believed that they cannot guarantee the same longevity as traditional masonry houses, or that they do not offer the necessary comfort and ideal insulation.
Instead, the technology currently used for the construction of prefabricated houses manages to equate, and in some ways exceed, the comfort and quality of life that traditional construction can ensure.

Many examples of wooden houses are present on the site of Pineca manufacturer and designer of wooden houses.

In fact, in Italy, wooden constructions are still few and in a clear minority as a percentage of new constructions. This is a trend destined to change radically in the coming years. In fact, there is already a progressive increase in this field today.
Traditional limits, such as the difficulty of creating a mezzanine or a second floor, are progressively overcome by the many improvements in the design and construction phase. The technology used for the construction of the supporting structure, the panels, their construction and subsequent assembly ensure the perfect stability of the building.
It is no coincidence that the wooden modules are the most commonly used for rapid and decisive reconstruction in earthquake areas. The performance of wood in absorbing the oscillations of the ground in the event of an earthquake is notoriously better than the more rigid masonry structure.

What is the best wood to make prefabricated houses?

Much of the positive outcome in the construction of a wooden house depends on the most careful and prudent choice of raw material.
Not all wood is the same and often its characteristics also vary according to the age of the plant and the type of processing it has undergone.
Certainly the best performance expected is obtained with a good starting wood. In this case, spruce is certainly the optimal choice and guarantees the best performance over time.
Other aspects that increase the yield of the material must also be taken into account. If spruce is basically an excellent raw material, the importance of proper seasoning should not be underestimated. This process is essential to make the environment inhospitable for xylophagous insects and the formation of rot or other episodes that could compromise the solidity of the structure.
It is difficult to opt for solid wood, a good alternative is the choice of beams and laminated panels, worked in such a way as to withstand the stresses of atmospheric events and always guarantee the maximum solidity of the structure at a lower cost.

The thermal insulation system for the best insulation and lower heating costs

All new buildings must ensure the best performance in terms of limiting consumption for space heating.
Well insulated walls mean greater stability and pleasantness of the temperature inside the house.
One of the characteristics of wood is to gradually transfer heat. This translates into greater ability than brick to keep the environment cool in summer and warm in winter.
A slower transfer of the internal temperature is also facilitated by the presence of good insulation of the walls. This is why it is important to consider that in the best prefabricated buildings, the wood of the load-bearing structure hardly remains visible. In fact, it is advisable to cover it with insulating panels that improve the sealing and protective performance of the wall.
Rock wool, polystyrene (PES), but also natural materials such as wood fiber, cork or recycled fabric, are just some of the solutions used to create the thermal coat.

Removing stagnant water is the priority

One of the aspects that the designer of wooden houses must carefully consider concerns the possibility of creating pitched roofs to remove rainwater.
This represents, especially if it remains stagnant, one of the most serious problems in construction, both the common one such as the innovative wood, must deal with the need to remove water from surfaces as quickly as possible.
For this it is necessary to provide the best drainage and dripping system, especially when the project requires the construction of flat roofs and terraces.
The use of insulating materials for the pitched roof certainly represents the best alternative, more practical and economical, clearly it must be carefully considered together with the client of the project.
