Health is in first place among all the factors that determine the quality of life. This is shown by all opinion polls. People’s priorities remain unchanged for a long time. The quality of life depends on four components: stable earnings, a sense of security, health, as well as the environment that directly affects it. Sustainability today is expected in everything. Building materials are no exception. But at the same time this question is surrounded by many myths.
The first myth concerns the mandatory naturalness of materials. They try to avoid synthetics by choosing natural products. However, a combination of chemical elements is everything. Alumina and silicon oxides, for example, are present in soda, polymers and other components are present in wood. Outside the dugouts, which can be considered the standard of environmental friendliness, our life has long gone. Nobody uses wagons or walk in bast shoes. Modern materials surround us everywhere. So is it worth worrying that natural products began to be replaced by more convenient and practical artificial counterparts in construction?
The myth that eco-friendly materials cannot emit any harmful substances is also very persistent. However, in practice, everything is different.
Even the most natural materials are accompanied by the use of glue, varnishes and much more. A large number of organic poisons are present in wood, as they help fight microorganisms and bacteria, and increase the life of materials.
The third myth is the need for "breathing" of building structures. In fact, we are talking here about the ability of a material to trap or pass steam. Air exchange is provided in modern homes by ventilation systems. Even wooden walls cannot physically pass air, since a large number of heaters, insulators and the like are placed next to them. It is from heat-insulating materials that the environmental friendliness of the house most often depends, or rather, from their correct choice. The structural elements themselves do not matter much.
The fourth myth concerns the gradual loss of environmental friendliness. In fact, environmental friendliness is a complex concept, that is, it should be considered in this case the entire life cycle of the material, including its disposal and transportation. In practice, synthetic polyurethane foam makes it possible to save significantly more energy than the one that was spent on its production. Therefore, it is environmentally friendly, despite its artificial origin.
Among the common misconceptions, one can distinguish the illusion of the high cost of environmentally friendly products. With the right approach, a house that is not harmful to health can be cheaper than evaporating harmful substances.
