Aerated concrete or brick - a comprehensive comparison

For houses in solid construction, there is always the question of the building material. In recent years, aerated concrete is becoming increasingly popular. What advantages and disadvantages he has compared to bricks, and which of the two building materials best fits where, this guide explores in detail.

Aerated concrete properties

Aerated concrete is a modern building material that has been developed for around 50 years. It consists of a steam-hardened quicklime-sand mixture.

Due to the pore structure, aerated concrete is extremely light. This brings with it some advantages:

  • lighter overall constructions, therefore also static advantages
  • easy processability even in large formats, thus time advantage and cost advantage
  • lower transport costs

In addition, aerated concrete also has very good thermal insulation properties. Additional insulation can be made much thinner, or completely eliminated. This also creates a cost advantage.

Aerated concrete blocks can be processed very easily - especially as plan stones. With the possible use of thin-bed mortar, the mortar consumption is significantly lower than with brick walls.

Autoclaved aerated concrete and brick

Self-walling with aerated concrete blocks is easy and comparatively fast. Tiles only need to be placed on a thin bed. The working speed is about two to three times as high as brick walls.

Due to the low weight of even large stones and easy handling, a faster construction progress can be achieved. It also requires less qualified helpers. Autoclaved aerated concrete is the ideal building material.

For brick walls more craftsmanship and technical knowledge is necessary. The brick walls are more complicated.

At most, the comparatively high water absorption capacity of aerated concrete blocks can be felt as a disadvantage - in construction, this disadvantage can almost always be easily compensated.

thermal insulation

The thermal insulation of aerated concrete blocks is so high that in monolithic construction usually no further thermal insulation is necessary. This construction also automatically eliminates thermal bridges. The requirements of the EnEV are far exceeded by monolithic construction with aerated concrete blocks.

In the brick sector, although special thermal insulation bricks can be used, which already contain insulating material, but they are laborious to process and are priced significantly above conventional gas concrete blocks.

Price advantage of aerated concrete blocks

The price advantage arises in the construction of aerated concrete blocks from several factors:

  • low production costs, therefore cheaper material price
  • lower transport costs due to lower weight
  • Time savings in processing (less labor, less time spent) thereby cost advantage in construction
  • Elimination of additional thermal insulation in monolithic construction
  • Overall lighter overall construction, thus saving due to changes in statics possible.

Tips & Tricks

The walls with aerated concrete blocks is relatively simple, but must still be carried out exactly. A briefing from a specialist is helpful here.
