Perhaps even the formation of phosgene. Carcinogenic properties have mainly fiber thickness of less than 3 microns and a length greater than 5 microns. Polystyrene plates are widely used for insulation of buildings. Harmful properties of asbestos are manifested only when asbestos fibers are included in the products and materials into the air and then penetrate the human respiratory system.

Effect of. Исследования this material in construction have confirmed the allocation of a significant amount of free formaldehyde. S. In construction, it can almost completely replace the asbestos volokno. In this regard, the authorities were forced to ban n ПенополиуретанЖесткий foam also is widely used in construction. Therefore we can assume that the probability of cancer due to use in the construction of mineral wool is extremely low. Polistirol plastic mass. In spite of the tolerance for use in construction, polyurethane has negative qualities in terms of health safety. Therefore, you should read them and study their properties in terms of security for zdorovya. The main fields of application – this is the thermal insulation of walls and ceilings. Their allowable concentration in the air at the workplace is 0. Prepolymers, soft polyurethane resins, hardeners isocyanate is very dangerous to humans. It should be added that the so-called samopogasayuschy Styrofoam is not flammable material and the fire highlights the relatively small amount of toxic gases. 5 m space, you can expect that even use the maximum number of these plates will not lead to excessive air pollution by formaldehyde. 05 mg/m3 of air, and the minimum air exchange equal to 0. In performance is an excellent building material. V present production and use of asbestos declined significantly, mainly due to the reduction of its use in construction. By themselves, these materials are harmless to humans, but after impregnation they can become hazardous to health. Studies show that the board allocate a very small amount of formaldehyde, usually less than 0. He even used to manufacture toys, pipes, and a dust mask. There were several thousands of different kinds of products, including well construction components and materials for the manufacture of which used asbestos. 05 mg/m3. More… Above the main shortcomings of housing was due, primarily, the lack of appropriate market insulation. It is widely used for thermal insulation of flat roofs, for example, in the large factory floor. Mineral wool also has excellent thermal and sound insulating properties. As a result, often there have been cases of strong, threatening the health of air pollution by formaldehyde in buildings. In this regard, are particularly harmful diisocyanates. Used for the manufacture of polystyrene foam does not pose any danger to здоровья. PolistirolV as insulating materials, especially for reducing heat loss through the exterior building elements, are widely used organic plastic. Crucial to the size and shape of fibers. And Canada. If these three major blemish housing could somehow estimate the value of residential buildings would have to decrease by about 30%. Insulation materials of vegetable origin in contrast to the above materials and products, plant materials – mainly wood-fiber boards, as well as non-woven fabric or cloth from plant fibers such as Utah, hemp – a little resistant to the biological factors in connection with which they are used after preliminary impregnation of fungicidal drugs.
