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...

European Experience If you look at a major European city with a plane, it is easy to see: about 60% of its territory is covered by roofs. Wise Europeans have long been multiplied expensive land in the city on the ability of modern building technology. And they came to the need for roofing as additional areas. In Ukraine, their experience will not be superfluous. Let's start with definitions. Operated roof - is a special design, intended for the movement of people or vehicles, recreation, growing green plants, etc. Such roofs can, for example, to solve the problem of creating a playground or car park in the center city, where there is no free space. The main advantages of the exploited roofs - they increase the efficiency and functionality of the operation of (it turns out, in essence, an additional floor). In the case of a "green roof" important is also the question of ecology. Additional advantage of such roofs - covering under the protection of the working layer, and there are no problems with ultraviolet light. In addition, improved thermal engineering characteristics, so you can apply a thin layer of thermal insulator. But to be fair to say and some of the shortcomings of the exploited roofs. These include the significant additional costs, more high demands on material selection and installation of roofing tiles (this is due primarily to the complexity of repairs), higher demands on the statics of the roof of the large weight, the need for continuous care operated surface. Operated roof is a "layer cake". From top to bottom layers are as follows: Exploited layer Separation layer Insulation layer Waterproofing layer and vapor control layer The layer, which creates a bias internal supporting structure of the roof covering Pedestrian Pedestrian operated roof can be divided into restricted and unrestricted in use. Limited. Movement on a roof is only allowed within the established zones.
