Heat exchange through composite walls

Abstract

We investigated the heat conduction through different composite walls and analysed heat balance - thermal efficiency on both sides of the walls. Advantages are commented and the necessity of thermal isolation is emphasized. Examples of several combinations for two ways of passive isolation are analysed. Numerous materials for thermal isolation are presented and value of the overall coefficient of transmission is calculated for different combinations. It is concluded that for construction of walls it is better to use shallow brick rather than full and that it is more efficient to place thermal isolation on the exterior side of wall because only in that case continual isolating layer can be realized.
