Natural stone shells have quite high indicators in sound and thermal insulation. The only thing that drops the merits of the shell, is that the shells requires reliable waterproofing from moisture, especially in the winter period of time. Moisture that enters the shell -grinder, in the absence of or poor -quality waterproofing, can freeze inside porous stone. The freezing of moisture inside the shells acts on the destruction of the internal structure of the shell, which reduces the quality of its fortress.
It is for this reason that the shells should not be used as bearing external walls in the lower floors of a multi -storey building. Basically, the shellship is used to build low -rise buildings, utility rooms, garages and cottages. If a shell is used in the construction of the house, it is better to use it on utility rooms or to the second floor, which will not carry a heavy load of the first floor. Must be installed on the site so as not to go far for water.
Regarding the protection of the walls from the shell, then as waterproofing it is necessary to use high -quality waterproofing membranes, and when warming and facing walls, it is advisable to create a ventilated facade, which will not allow moisture to penetrate the walls. Also, for insulation of walls from shells, you should choose a high -quality insulation – basalt cotton wool or polyvinyl chloride fibrous soft bags.
