Wood, perfect insulation in summer

Why build with solid plywood 

Today build design houses with wood is perfectly possible and even desirable from many points of view. It is a growing trend year by year winning advocates use both professionals and among customers, something that the industry has also managed to detect and leverage and improved the supply and variety of products.
From the point of view of respect for nature, wood is the building material has lower carbon footprint and, therefore, is the most sustainable. Its insulating characteristics makes it a very useful material as an enclosure, as it simplifies construction and minimizes the need for specific insulation materials. Structurally, the laminated wood is a predictable, stable, durable material and ensuring the soundness of the structures built with it. Finally, aesthetically, it is a very visually pleasing material can be used uncoated, providing an aesthetic and warmth to the spaces value.

Improved laminated timber

Manufacture of plywood is a technique that has been developed relatively recently, mainly throughout the twentieth century to transform it into a much more reliable, durable and economical material. From raw wood, thin and long sheets, which are assembled with high-strength resins without formaldehyde and by a process involving high pressures and temperatures are extracted. The result is a homogeneous material in its structural performance and extremely stable against humidity and temperature changes.


Thanks to laminate, wood can be treated very effectively against attack by pests, moisture, fungi or even fire. It also facilitates the process of drying and curing a material such as wood required to avoid undesired deformations and cracks. In the case of laminated wood, the assembly is performed by alternating layers and varying the direction of the fiber, which improves the natural resistance of a material nature has created to resist very well in one direction. The crossed fibers prevents mainly the occurrence of longitudinal cracks and deformation or buckling of large parts.



In addition to the production of beams and columns large, which can save similar to the structures of other materials, such as concrete or steel lights, and withstand without problem the same charges, the plywood being allows manufacturing cladding panels with structural capacity. This application is very interesting because it greatly expands the role wood can play in modern homes. Imagine a house built entirely of wood can lead us to think in typical Nordic style hut made of stacked logs. However, it is now possible to build modern houses where wood is the protagonist and without sacrificing the sophistication of contemporary design, the strength of the work accomplished with conventional materials or facilities that provide a high level of finishes.


The good thermal behavior of wood

If we think about how laminated timber equals benefits than other materials commonly used in construction (such as ceramics, concrete or steel), choose to build with wood can be a matter of taste. But, if you also consider the excellent thermal behavior that wood, decide to use it can be a future investment.


A very practical way to understand why wood works so well against temperature changes is to think what we feel when we touch a metallic element that is the sun in summer. Almost certainly it will be unbearably hot. What happens if we touch a wooden railing? His touch will be warm, but never reach high temperatures. Exactly the same happens against low temperatures, when contact with the cold metal can even make the skin adheres somewhat.


What is this about? The explanation is simple. It is because the internal structure of wood, the fibers are formed by numerous cells cellulose, the same material is made of paper. Once dried and treated, they are hollow and filled with air. Air is actually the best of insulators and insulation all present in the construction market seek trap air bubbles within the material structure. For this reason, the best insulators tend to be very light.


The consequence of that wood is as good thermal insulator when we use it in the construction of a dwelling is to replace wholly or partially the use of insulation such as expanded polystyrene (white cork), extruded polystyrene, polyurethane foam or rock wool. Walls can be built entirely of wood and are able to isolate the inside from outside temperatures. And although the comfort of a wooden construction we always associate in cold, we must say that in a hot climate this can have a very positive impact on both the quality of the indoor environment and a reduction in electricity bills.


Another very important feature of thermal wood is its low heat absorption. Because it is much lighter than other structural materials as it is extremely more insulating than these, wood is not able to absorb a lot of heat, as if they have heavy brick walls, concrete or stone. Similarly, the wood also emits large amounts of energy and its behavior, in this sense, is very slow, which helps maintain stable better climatic conditions inside our house. This benefits us in making use of air conditioning in summer, which is a type of installation that only changes the air temperature and, therefore, once stops working much more efficiently, the internal temperature rises rapidly from the heat that floors, walls and ceilings outputted.



What are thermal bridges and why avoids building with wood


Thermal bridges occur naturally in any construction in which different materials are used insulation capacity, whether or not used as insulators. Imagine you have a very well insulated wall by a thick layer of rock wool in most of its surface. It is well insulated, but right on the corner of the house the rock wool layer is interrupted where the wall meets a steel pillar. In the area where there is less heat and cold insulation pass freely through the steel, whose thermal behavior is very bad in terms of isolation. thermal bridges can occur almost anywhere in the house, but especially where different elements are joined together and there are material changes. Corners between walls, pillars embedded in walls, window frames or encounters between walls and floors or ceilings are places where thermal bridges often occur.


If the jumpers terms are not properly controlled, they will introduce very hot during summer and let you escape in winter. The consequences will be more than obvious during the summer and the air conditioning system you will be forced to expend more energy to counteract the heat source. While in winter it can work, even worse, as the negative effect of heat loss heating adds that in areas considered bridges terms may form condensation water. These spots indoor humidity often become a difficult problem to tackle and that can affect air quality, spoil the interior finishes and disfigure the appearance of the house.


As mentioned earlier, in most cases, thermal bridges occur because of structural (usually steel or concrete) elements, but what if our structural elements are inherently insulators? If our house is built with solid wood structure contralaminada, pillars and beams, due to its own constitution and thickness, it will be more insulating than the walls themselves. Thus, the problem of thermal bridges is virtually eradicated and no longer an issue to be monitored as closely as in other cases.



Wood, the material of our century


As we have seen, building with wood structure CLT technology combines a host of unique advantages with those of any other construction system. The beauty and health of this natural material, we must add its great versatility to design space dream, strength and durability, energy conservation and sustainability.
