Thermal Insulation Applications on the Inner Surface of the Walls
This system, which is frequently applied in residences today; It gives more positive results when applied in places that are used for a short time and do not require permanent heating, such as office buildings, concert and movie theaters. In this system, the heat storage ability of the walls is low, but the preheating time is short. In case of thermal insulation from the inner surface , sheathing as a result of vapor diffusionCondensation possibility is extremely high for the purpose of material. For this reason, a vapor barrier material should definitely be used in the hot direction of the insulation boards (Figure 2). The insulation applied from the inside is especially applied in the thermal insulation of the owned buildings and in cases where external thermal insulation is not preferred. However, in these programs, it is necessary to take measures to eliminate the thermal bridges that occur in the parts where the floors, columns, beams and curtains are connected to the outer wall. Despite the negative aspects such as the difficulty of the program technique and the increase in cost seen in externally insulated walls, the simplicity of the program and the decrease in cost in walls insulated from the inner surface are considered among the positives.
Among the advantages of the insulation applied from the inside are that it does not affect the exterior of the building, does not require scaffolding, is not affected by the external weather during the program, the program is simple, it allows the program for the desired place or wall, and it is more economical. However, as a result of thermal stresses caused by temperature differences in the insulation from the inside, deteriorations and cracks may occur in the internal structure.
