Wooden construction, at least one that incorporates the most avant-garde techniques and means, is a trend in the architecture sector. The cross laminated panel (clt) is called revolutionize construction, and that is.
Modern wooden houses proliferate all over the world, especially in countries where this material has already been used to build. Northern Europe, mainly the United States and Canada.
In many others, such as Spain and some Latin American countries, prejudices exist regarding this type of construction. Some of them were never true and others were overcome by the technical advancement of wooden construction. But even in these countries, there is a decided advance in the sector.
There are several reasons that justify this increase in demand, and although we detail them later, it is worth mentioning the most important reasons: reduction of energy consumption both in construction and in the daily lives of users, use of renewable resources, less time construction, high durability.
Materials used for the manufacture of modern wooden houses
Many will say that wood is not exactly a new material unknown to humans. True, it has been used since the beginning of time. But it was only in recent decades, thanks to innovations related to chemistry and mechanics, that it was possible to manufacture what is known as laminated wood.
What is laminated wood? These are pieces of wood made of several smaller pieces of wood joined together by glue and pressure. The result is beams or panels with excellent physical and mechanical performance that allow the construction of larger and more resistant structures than those allowed by natural solid wood.
In modern wooden constructions, the predominant material is clear wood, but it need not be the only. Glass has an important presence, as it is increasingly common to find walls that have been replaced by glass to improve the passage of light and the visibility of the interior. We can also find concrete and steel on many occasions, but their use is not always restricted to foundations.
Current construction methods
Laminate panel construction
This is the most innovative way of construction of modern wooden houses. Large panels of glued laminated wood are used that come together to form the building.
Each panel can be the floor, a wall, etc. They are manufactured in the workshop so that each one arrives at the construction site ready to be assembled and machined: cuts, doors, windows, etc. To simplify it would be like assembling a puzzle with cranes.
Some of the advantages of performing this task in a workshop are that the duration and the need for manpower are greatly reduced, errors are also reduced and there is access to machines that normally cannot be moved to work.
It’s not just used to build houses either multi-storey buildings and even skyscrapers.
Heavy and light fabric
The construction of half-timbered houses and / or buildings consists of the construction of a wooden structure, which is then covered, not necessarily with wood, although it is common.
The difference between the two does not refer only to the size of the beams. In heavy structures, the use of nails and steel-based joints is avoided, using more assemblies or joints that take advantage of the tension of the structure. The spacing between the beams is larger and the backfill being made on light trusses is more complex or even unfeasible.
The light structures, where mainly solid wood is used, are not exactly avant-garde. In fact, it is a very traditional way of building wooden houses. The innovations in this area have much more to do with the architectural design and the use of other auxiliary materials.
Prefabricated, modular and customized
As with other construction methods, it is possible to buy modern wooden houses in different ways, depending on the level of customization.
On the one hand we have fully customized homes of the user. Here the customization is total. In this case, the price is usually higher.
We have a middle ground, modular wooden houses, where a series of modules are designed previously. The user decides how many to use and how to combine them. the possibilities can be many, although never so many as in a custom construction.
Regarding the prefabricated wooden housesDesigns are practically manufactured in series and where the possibilities for customization are very limited. While this may seem like a disadvantage, keep in mind that the price is lower and that the designs are tested and highly refined.
Advantages of wooden construction
- Wood is the natural, renewable and recyclable building material par excellence. In combination with the correct exploitation of forests, it represents the future of construction.
- It is a natural insulator. It allows significant savings for users, even without applying additional insulation.
- Drastic reduction of time and manpower, especially with regard to the environment. There is also less energy consumption during the construction process.
- The wood has a high load capacity despite its lightness. Therefore, the structures are lighter and smaller foundations are needed.
- It can be built with wood in any area. Cold and rainy climates, by the sea, etc.
Prejudice and / or inconvenience
Price. The price of wooden houses is not necessarily lower than that of other options. The raw material is more expensive, although there is a significant saving in direct labor and time. Each case would have to be analyzed independently.
Fire. Wood burns, of course. However, wooden structures do not collapse as quickly as many think. They do this predictably, allowing architects to calculate risks, and slowly.
Maintenance. It is often said that wood needs maintenance, it is true. This argument is often used as if the alternatives do not need it. The brick facades of the city are painted, repaired because pieces fall, there are humidity problems, etc. With modern wooden constructions, where the wood has been properly treated and dried, the needs are very similar to those of other construction methods.
