What is Thermal Insulation of Buildings?
Thermal insulation is an important technology to reduce energy consumption in buildings by preventing heat gain/loss through the building envelope. Thermal insulation is a construction material with low thermal conductivity. These materials have no other purpose than to save energy and protect and provide comfort to occupants. In general, people living in hot regions wants to make their inside atmosphere very cool similarly people living in cold regions, wants warmer atmosphere inside. But, we know that the heat transfer takes place from hotter to colder areas. As a result, heat loss happens. To overcome this loss in buildings thermal insulation is provided to maintain required temperature inside the building. The aim of thermal insulation is to minimize the heat transfer between outside and inside of building. We do these services in Coimbatore, Palakkad, Tirupur, Erode, Metupalayam, Ooty, Munnar, Pollachi, Valparai, Udumalpet, Marayur.
Basically there are three possibilities for the positioning of the insulation layer within a structural element. These are external, internal and core thermal insulation. The external one is the most favourable one. The whole building is enclosed within a gapless thermal skin. Thermal bridging and the under-cooling of the buildings structures are avoided. A special form of external insulation is the perimeter insulation which encloses all structural elements having soil contact. The perimeter insulation is positioned vertically at the basement walls and horizontally under the basements floor outside the buildings sealing layer. It has to meet structural stability criteria and long-term endurance to moisture exposition. An example for external insulation are the integrated insulation systems, which are also called a thermal skin. It consists of an insulation layer, a reinforced layer and a final coating. The reinforced layer and the final coating protect the insulation material against mechanical stress and effects of weather. The core insulation is positioned in the cavity of a cavity wall. The cavity is either completely or partially filled with the insulation material, leaving space for an air gap, which can be used as an additional insulating layer or to ventilate the cavity and hence quickens the drying of the insulation material. The cavity insulation is used in renovations as well as in new buildings. Internal insulation is preferred during renovations due to the fact that here no problems are caused concerning the protection of historic buildings or other civil rights. Disadvantages of this placement are, that the building construction is under-cooled in winter and the hardly controllable difficulties related to thermal bridges. Furthermore, the summer overheating problem is increased by the reduction of the thermal capacity on the interior surfaces.
Insulation materials have to keep their shape, be durable and resistant against mould and parasites. The moisture balance of the construction has to be positive, i.e. the water accumulating inside the construction during the thawing period (winter) has to be removed to the exterior during the evaporating period (summer). The placement of a wind tight layer at the outer surface and an airtight on the inner surface prevent the insulation material form being perfused with humid and warm room air from the inside or cold ambient air from the outside. Depending on the field of use, the insulation material have to suffice the safety requirements for fire protection.
