Get To Know The Most Used Materials In Sustainable Construction
Energy efficiency and sustainability
The various materials to be used for the construction of a sustainable building must be committed to the pursuit of pollution reduction. We must evaluate the environmental impact of the products used, try to work with materials with the lowest possible level of industrial processing, or directly recycled such as vegetable, animal or wood fibre.
In addition, many materials not only have less environmental impact but also have better performance. In the case of wood, its insulating capacity far exceeds that of concrete. It manages to muffle noise while maintaining a stable temperature inside the building or home. In addition, with the appropriate treatment it can regulate the humidity of the environment.
In search of the perfect material
It is so important to find sustainable building materials, that there are branches of engineering, such as Materials Engineering, which is concerned with finding new ways to manufacture materials while producing as little environmental impact as possible.
An example of these practices is being developed by researchers at the Massachusetts Institute of Technology (MIT), who are investigating different formulas to make the manufacture of building materials as sustainable as possible. Their latest research is based on finding new ways to manufacture cement without producing greenhouse gas emissions, which today represents 8 percent of the world’s total.
Cellulose insulation is made from waste paper and is currently one of the most widely used on the market, and can be said to be completely recycled. Also in panel form, the cellulose has had to be treated to protect it from fire and prevent mold and even so, its production cost is very low.
Also the wool insulation, coming from the sheep is known for its thermal capacity when it gets wet and for its capacity to expel its humidity when the environment changes from wet to dry.
For openings such as doors and windows, the common strategy is triple glazing with two air chambers. One of the chambers is filled with Argon (gas) which causes a great thermal insulation. For carpentry, the material par excellence in recent years has been PVC (Polyvinyl Chloride), which is an economical material, easy to maintain and highly energy efficient.
