Advantages And Disadvantages of Wood

Advantages of Wood

Dry assembly and possibility of prefabrication

it is much faster and easier to work than wet construction, allowing less material waste and reducing execution times. If it is prefabricated, it dramatically increases the control with its consequent reduction in terms and defects of the material and assembly.

Advantages And Disadvantages of Wood

Thermal insulation

Since wood hardly conducts heat, it eliminates thermal bridges that are difficult or impossible to avoid with other materials. If a good design is added to this, most of the pathologies that afflict current homes can be prevented.

Sustainable and ecological

On the one hand, this material eliminates thermal bridges, reduces energy consumption. On the other, it is of natural, recyclable, and renewable origin, whose elaboration compared to other industrialized products offers less waste, requires low energy consumption, and respects nature and the environment. It is entirely renewable if logging is done correctly and with the relevant certificates that guarantee the resource’s repopulation and care. Also, it is reusable.

It admits low maintenance coatings

Wood is an organic material, and as such, if it is exposed to certain weather conditions, it requires unique treatments. Instead, it allows different types of finishes to be used that reduce the said need for maintenance. For example, inside wooden houses, Canadian houses are not prefabricated, but they have more outstanding durability and less maintenance than other systems.

Versatile and easy to handle

It is a raw material that supports a wide variety of jobs, joints, and assemblies. It also supports many uses and dimensions, whether for structures, substructures, or decorative finishes.


It is a material whose durability has been proven over the centuries in traditional construction. Adequately designed and protected, the structural wood can last for hundreds of years without significant damage.


one of the most distinct advantages is that it is much cheaper to build in wood than in concrete, brick, or steel. Why? Because the material itself is abundant, it requires little manufacturing. It is effortless to transport and handle thanks to its low weight and because dry construction substantially reduces construction times (even more if it is a prefabricated system).

Mechanical resistance

Structurally it works well in traction, compression, and flexion. If we compare it with materials such as concrete and steel of much greater weight and cost, we may be surprised: (according to CTE. 2011 values), when compressed, wood has values ​​between 16-23 N / mm 2, reinforced concrete: 20-30 N / mm 2 and steel 215-460 N / mm 2 while in flexure 14-30 N / mm 2 in wood and 1.5-5.0 N / mm 2 in concrete. Structural steel, in this case, has very high bending strengths. With this, it can be seen that wood easily achieves flexural values ​​ten times higher than concrete.


It is a factor to consider, the lower the weight, the more material can be transported in a single truck, fewer people and simpler machinery are necessary for its handling, the lower its weight has to support the structure, etc … everything that influences quantities and costs.

Disadvantages of Wood

It requires a lot of control

As I have already mentioned before, wood is an organic material, and this means that it is susceptible to alterations by different factors such as humidity or xylophagous insects. For this not to happen, they require meticulous control and a series of unique treatments depending on the use that is going to be given to the piece. This requires being strict with the certificates that are needed, among other issues.


Especially if it will be exposed to atmospheric factors, the wood has to be treated from time to time with varnishes, paints, seals, or other processes that maintain its properties. A “beautiful” wood requires effort, but in any case, it makes it more valuable. This is not why we should be afraid that it will quickly spoil, an example that we all have in our minds would be a port dock made of wood, and the wood will hold up correctly, saltwater being one of the most corrosive substances there is for buildings.

Not feasible for the entire population

Fortunately, or unfortunately, not everyone likes wood, but what is clear is that there is not enough wood to build houses of this material for everyone in a sustainable way. With this, what I want to imply is that more should be made in wood, but not that everyone does.

Reaction to fire 

Later I will explain this aspect that has made more than one person sleep without need. Just mention here that wood reacts poorly, but it resists fire exceptionally well.

Usually reduced dimensions

Traditionally large buildings have hardly been built (avoiding large stone constructions such as cathedrals) until the appearance of steel and reinforced concrete. The most significant distance that could be bridged in the wood was the trees’ length that could be cut. Nowadays, new technologies make it possible to “join” wooden beams (laminated timber) and bridge greater distances. Still, it is a way of building that is not very widespread in our country.


Not all trees are the same, and therefore not all the woods that are extracted from them. Each species has different properties that make them more suitable for some uses or others. Even within the same species, there may be critical physical variations such as knots or cracks. That is why it is necessary to be well informed about the wood classifications before prescribing them, be it decorative, structural, exterior finishing, etc. For example, a young pine is softer than oak, so the former will be more suitable for slats and the second for structural beams.
