Is the thermal insulation performed only on the outer walls sufficient?

       In a building, thermal insulation should be applied to the floor and roof along with all the facades. Contrary to popular belief, heat losses or gains are caused not only by the façade but also by the heat transmitted from the roof and floor. Since the floor of the building is a reinforced concrete element, the floor acts as a thermal bridge and transmits the heat drawn from the columns of the building to the ground quickly, causing heat loss. On the other hand, since the heated air in the building rises to the attic in accordance with the law of physics, heat losses from the roof are also high. Instead of laying flat slabs between floors, building elements that will provide insulation should be used, and the attic floors should be insulated from the floor or rafter level. In addition, the windows must be correctly selected as joinery and double glazing according to the climate zone.
