Linear Thermal Transmittance of Holding Unit of Balcony Slab to External Wall

Abstract

The balcony is one of the main reasons of the increased heat loss. If the balcony construction is performed of a metal back slab it would be hardly possible to avoid the formation of a powerful thermal bridge that will go along the whole balcony length. This problem could be solved by the thermal isolation of the wall which is the balcony support or by carrying out an integral thermal isolation of both the wall and the balcony. In the article the estimation and comparison of the six possible variants of the construction thermal isolation has been carried out. With the help of the two-dimensional thermal field the linear thermal transmittance and the temperature in distinguished points have been found.
