In construction, several types of masonry are distinguished — solid and lightweight. Continuous masonry is convenient in that one single material is used. However, the thickness of the wall as a result is quite large, about 640 mm, which is not always satisfactory. The use of hollow brick allows the wall thickness to reduce to 380 mm.
Lightly masonry is also selected with the desire to reduce the thickness of the outer wall. Such masonry is characterized by a combination of more efficient and heating materials along with the usual. Given their properties, they are introduced into the masonry either from the inside, or from the external. For example, light concrete slabs are suitable for external atmosphere cladding, and fibolytic slabs are an ideal choice for thermal insulation from the inside.
Thermal insulation layers are laid either close to the wall, or with the formation of a small air gap (about 2-3 cm). The slabs are mounted on special metal rails, which are located horizontally and vertical. Thus, hotel rectangular compartments are obtained, which create an air layer and maintain the temperature-humid regime.
