Construction and front brick is determined by the presence of voids in it. By the presence of voids, bricks are divided into hollow, hollow porous and full -bodied. Full -bodied bricks have no holes. They are used to build the foundation, the base of the building, but you can make the outer wall from them.
There are holes of various shapes in hollow bricks, due to which their thermal conductivity decreases. Therefore, the walls are made thinner – up to 1.3 meters. Hollow brick, as a rule, is always used for faces facing, as it is easier. Hollow porous brick is the most “warm” brick. He, like a hollow brick, has holes, but unlike it has a different structure of the material. In the manufacture of porous bricks, special mineral or organic additives fall into clay, which form microscopic closed pores when firing.
The strength of the brick does not depend on the presence of pores in it. Thanks to the pores, the product becomes easier and due to this it is possible to increase the size of the brick. As a result of this, the construction is faster, the walls become thinner, the masonry is simplified, additional thermal insulation is not required. In addition, there are grooves and crests on the sides of the porous brick, which makes it possible to abandon vertical solutions. Due to this, the solution is saved and the thermal protection of the walls is improved. Outside, the facades of the building are plastered or covered with facial brick.
