The above-ground segment of the house is mainly formed by the walls. Considering their exterior, not only their thickness is of big relevance – backing for the roof structure, but also insulating characteristics – protection against changing weather conditions and huge heat losses.
This last feature is particularly important in our climate conditions.
An important duty in which architects must succeed is the choice of an optimal technical project for the external wall insulation. In numerous situations, economic short-sightedness prevails and the compromise is made to apply single-layer wall technology without warming layer. In the multiple-layer wall purposes are split among two or indeed more components. One has only (or mainly) structural function, the second has a simply insulating purpose, and perhaps also another component of protective and decorative purpose. Therefore, thermic insulation relies mainly on the depth of the insulating material layer. Smaller or greater thickness of this layer does not change the composition of the surface (of the other layers) or the expense for its construction. The modification in thermal insulation (our links) features alters only the price of warming layer and affects the cost of the entire wall to a small degree.
Settling the most economically effective depth of the thermal insulation layer conforming to the principle of the shortest compensation period or the lowest costs of the long-term use cycle is supposed to be the starting place for the investor to make a decision on the selection of wall structure and diameter of the thermal insulating component.
