The influence of thermal insulation materials on human health

Inache is the case with mineral or glass fiber, manufactured by industry. In performance is an excellent building material. In this regard, are particularly harmful diisocyanates. In case of fire may form highly toxic gases. If these three major blemish housing could somehow estimate the value of residential buildings would have to decrease by about 30%. In this regard, the authorities were forced to ban n It is characterized by considerable stability to high temperatures and chemicals. They cause allergic reactions and severe forms of respiratory ailments. A list of various insulating materials is very extensive. 02 mg/m2 surface of the plate for 1 hour. One faction of mineral fibers contained in the mineral wool, carcinogenic, and the binder used in the production of mineral wool – phenol-formaldehyde resin or melamine – in a long time allocates free formaldehyde, which is highly toxic, carcinogenic and suspected in Mineralnaya wool, as mentioned above, contains phenol-formaldehyde resins, which leads to prolonged release into the environment of free formaldehyde. In terms of health safety of mineral wool has two major drawbacks. This was due to the numerous protests of institutions and individuals involved in the protection of the environment and health. And Canada. Due to the exceptional qualities of asbestos fibers – a very high mechanical strength, resistance to aggressive chemicals and high temperatures – in some cases, asbestos is irreplaceable, and therefore allows the possibility of its further application in industry and even in construction, but in much smaller scale than in the past. AsbestAsbest, being very resistant material, has many technical advantages have been used in various industries. It should be noted that the experts of the World Health Organization, engaged in harmful effects of asbestos products, are wary of asbestos on exclusion from various areas of application. Therefore we can assume that the probability of cancer due to use in the construction of mineral wool is extremely low. 05 mg/m3. In spite of the tolerance for use in construction, polyurethane has negative qualities in terms of health safety. Given the practical aspect of mineral wool in the building, it is best to use it in the form of plates and laminates, as it facilitates the construction raboty. Their allowable concentration in the air at the workplace is 0. Very polystyrene is widely used because it is fairly durable, non-toxic and is easy deshev. Its main component is styrene. When the permissible concentration of formaldehyde in the air in a residential area of?

PPLICATION krilamidnogo foam for use in строительстве. This applies to both asbestos fibers and mineral fibers produced by the industrial method. 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. Unfortunately, its main drawback is the prolonged excretion of free formaldegida. The reason for this was lack of knowledge of carcinogenic asbesta. Carcinogenic properties have mainly fiber thickness of less than 3 microns and a length greater than 5 microns. ПенополиуретанЖесткий foam also is widely used in construction. Studies have found that the mineral wool contains a small amount of fibers that may be suspected of carcinogenic action. Multilayer exterior walls or walls of cold storage also often contain polyurethane foam. It is widely used for thermal insulation of flat roofs, for example, in the large factory floor. In construction, it can almost completely replace the asbestos volokno. 4-2. Исследования this material in construction have confirmed the allocation of a significant amount of free formaldehyde. Used for the manufacture of polystyrene foam does not pose any danger to здоровья. Asbestos fibers in the proportion of these dimensions are very large, and therefore it is very dangerous for zdorovya. Mineral wool also has excellent thermal and sound insulating properties. It can be assumed that the polystyrene is used as a building material, safe for health.
