Most of buildings, a thermal loss occurs in a structure, aperture, vent or gap. Insulation is to minimize the heat transfers between the inside and the outside by increasing the heat resistance of a wall, window, roof or floor. Insulation materials are something that can minimize heat flows caused by conduction, convection or radiation.

The effect of insulation construction is to reduce the energy losses by 40 to 50 %. It is possible to achieve excellent heating conditions with a small amount of energy. Due to the characteristics of materials, it can absorb noises very well. Since a building with weak insulation performance requires a continuous flow of energies to the inside to maintain the indoor temperature, there is a large amount of heat loss. Also, it is directly related to the costs and the refreshing environment. Therefore, insulation is a very critical problem.
