insulation roof

insulation roof . To address energy efficiency, as well as to increase the comfort rooms, plays an important role warming of the building envelope : insulated roof, exterior walls, floors, coatings, etc. To do this, simply reduce their energy consumption by heater . When sovremnnom building an important role for the value of thermal resistance of roofs and ceilings, under which, new construction, modernization and repair of buildings can not be implemented without the use of effective insulation materials . Application of thermal insulation at the device mastic and roll roofs for flat surfaces outside the building to some extent reduces the cost of heating buildings by reducing heat flow due to increased thermal resistance of one of walling - cover. In addition, thermal insulation for flat concrete coating: protects roof insulation cover from the effects of variable ambient temperatures, smooths fluctuations in temperature the main file cover, thereby avoiding the appearance of cracks, due to uneven temperature fluctuations, shifts the dew point to an external tepoizoltsionny Layer , which excludes otsyrevanie concrete or reinforced concrete solid surface; formed a more favorable microclimate by raising the temperature of the inner surface of the coating (the ceiling) and reduce the temperature difference between indoor air and the surface of the ceiling, including the attic. Use insulation to pitched roofs allows you to turn the attic into the living, which increases the useful area of the premises. A warming roofing from metal or sheeting prevents condensation on its surface in the cold time of year, it is very important for storage. It should be noted that the physical and technical properties of insulating materials used have a determining influence on the thermal efficiency and operational reliability of designs. When selecting insulation materials should be borne in mind that at dolovechnost and thermal stability and physical and mechanical properties of insulating materials within the construction fence, have a significant impact, many operational factors. This is, first and foremost, alternating (winter-summer) temperature-humidity mode of construction and the possibility of capillary and diffusion wetting insulation material , as well as the effects of wind, snow loads, mechanical loads of people walking, moving, transport and mechanisms on the surface roofing industrial buildings. As insulation materials , used in construction, work in fairly harsh conditions, they are increased requirements. First of all, pay attention to the coefficient of thermal conductivity l, W/(mK) material. It must be such as to insulating material , in operation, could provide the required resistance to heat transfer in the design, at the lowest possible thickness of the insulating layer. Consequently, predpochteie need to give a highly insulating material. In addition, the insulating material shall be frost (at least 20 - 25 cycles) to maintain their properties without a significant reduction in the strength and insulating characteristics to the repair of buildings, as well as be water resistant, biological stability, not to allocate during the operation of toxic and foul-smelling substances. Density of material used for insulation shall be not more than 250 kg/m3, or substantially increase the load on the structure, which must be considered when selecting materials for the repair of dilapidated buildings.
