Adequacy of materials used for building of dwelling houses

Summary
A health living in a room is conditioned by providing the possibility of the exchange of air at least two times per hour, eliminating any unpleasant effect of the draught at the same time. The speed of circulating and exchanging air shall be lower than 0.2 m per sec.
At a standard building the air exchange is effected through pores of the outside walls. The property of the material to transmit the air is called the air permeability of a material. It varies and depends upon the basic materials or raw materials from which the walls are built as well as on the method of building, the outside conditions of the air exchange and finally on mode of the treatment the inside and outside wall surfaces.
The further possibility of the air exchange in the dwelling room is favoured by the unadequate tightness of windows and doors. The amount of the air exchange is, in the West Europe, with the market items less than with walls, due to the porosity. However, in this country it is relatively larger, taking into account the surfaces which the exchange is mediating.
The air exchange in houses built in the standard method was enabled mediately through walls and windows, while in the monolithic concrete buildings the air is exchanged mediate through windows only which is in most cases too moderate.
The author states results obtained from theoretical studies and practical researches regarding the temperature of air, humidity air permeablility of some building materials as well as windows and doors.
