What are the properties of a brick

Properties of masonry bricks

Material for the masonry brick

The basic material for the bricks has in principle always been the same for centuries and consists of loam or clay that is burned. Temperatures of 900 to 1200 degrees are necessary for this. However, what is now made from this very original building material is impressive.

Properties of masonry bricks

  • Soundproof
  • open to diffusion
  • low thermal conductivity

Positive properties are improved

Bricks or bricks have good properties anyway. But these have been significantly improved by the new manufacturing methods and the additives. In the case of porous bricks, for example, styrofoam balls are mixed into the clay before the fire. When the polystyrene particles are burned, small air chambers remain in the stone. This reduces both the weight of the brick and the thermal conductivity.

The thermal insulation is improved even more if the holes in the brick are filled with perlite. As a result, in the case of an otherwise double-shell outer wall, only a single-shell wall structure is sometimes necessary. In this way, not only material costs but also high labor costs can be saved.

New bricks with exciting and good properties come onto the market almost every day. You should not necessarily only trust the advertising, but trust real tests by Stiftung Warentest or other respected testing organizations, especially with thermal bricks and special thermal insulation bricks.

After all, these stones usually cost a little more. But if you can find the right brick for your building project, you can actually save quite a bit.
