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.
