Cellulose Fibre Thermal

We consider three types of modern insulation: mineral wool, expanded polystyrene and ecowool. If the mineral wool has long been used in construction in Russia, the polystyrene is a relatively new material, and ecowool and at all exotic. All three materials with the technology of production do not rot, have good insulating properties, are inexpensive and easy to use. Mineral wool are processing of molten rock or slag. In the resulting synthetic vitreous fibers are added binders. It has good heat and sound insulation properties; when wet, these quality of mineral wool are significantly reduced.

This insulation is not flammable. The characteristics of mineral wool thermal conductivity, W / (m * K): 0,039-0,054 Group of combustibility: NY, G1, G2 Resistance to deformation: Average Water and biostability: low Destruction temperature, C 350 Density, kg / cu. m: 75-350 life, years: 20-30 Ecowool or cellulose wadding, as a rule, consists of 81% of the treated pulp at 12% - of preservative, and by 7% - of the flame retardants. In fibers of the material is lignin, which gives the sticky when wet. All components of this material are non-toxic, non-volatile, harmless to human natural ingredients. Cellulose insulation does not support combustion, not rot, has good heat and sound insulation. Ecowool capable of holding up to 20% humidity, which has almost no effect on the heat-insulating properties. Material easily gives moisture to the environment and when dry does not lose its properties.

Characteristics of Cellulose Fibre Thermal conductivity, W / (m * K): 0,036-0,041 flammability Group: G1, G2 resistant strains: low Water and biological stability: the average temperature of the destruction, C 220 Density, kg / cu. m: 30-96 life, years: 30-50 Expanded polystyrene - the material class of plastics, characterized by cellular structure. Characterized by high water and biopersistence, low specific gravity. A characteristic feature of polystyrene - a low fire, so it usually used at temperatures above 150 C. Burning polystyrene is accompanied by a large amount of smoke and toxic substances. To prevent such effects in this type of insulation material in the production of retardants are added. This is called self-extinguishing expanded polystyrene and its name is added to the letter "C" at the end. Soundproofing foam quality is not high. Thermal characteristics of polystyrene, W / (m * K): 0.04 Flammability Group: T3, T4 resistance to deformation, high Water and biological stability: high temperature fracture, C 160 Density, kg / cu.
