The most important part of the heat losses in buildings occurs on the exterior facades. For this reason, buildings should be insulated from the outside as well as from the inside. In addition, external insulation protects the structures against energy losses and ensures the continuity of the comfort condition.
The most suitable system is considered to be the insulation made from the outside in terms of building physics. The insulation made from the outside surrounds the building like a mantle and does not form a thermal bridge. Thus, stresses and cracks that will occur due to temperature changes are prevented, and the construction is kept constantly dry thanks to ventilation.
The thickness of the material chosen for the thermal insulation to be made on the walls and the choice of material are two important factors. In the processes to be applied for thermal insulation, the selected material should not absorb water into its structure (water permeability resistance), its vapor diffusion resistance should be high, plaster can be applied directly on it, it should be resistant to impacts and pressure, and its heat transmission coefficient should be low. In addition to these, the necessary calculations must be made in order to prevent the problems that will occur in condensation while choosing the thermal insulation thickness.
