Building materials for the solid house: properties, advantages, disadvantages

The good thing: With all four solid house building materials, the requirements for thermal insulation, soundproofing and living comfort can be met without any problems. Nevertheless, there are clear differences between aerated concrete, lightweight concrete, bricks and sand-lime brick - stone is not just stone.

Bricks: the number 1 among builders
Bricks (or bricks) are the favorite among builders who choose a solid home. Advantage of the building material: bricks are very robust, ensure a particularly pleasant room climate thanks to their moisture-regulating properties and enable very good thermal insulation. A filling made of heat-insulating perlite in the middle of the brick helps here. The disadvantage: Since bricks are made of clay that is fired at 1,000 degrees, they are very heavy. If you want to build massive buildings and do it yourself, you will probably not opt ​​for a solid brick house. Simple mud bricks are burned at only 900 degrees Celsius and have to be plastered because they are not so weather-resistant.

Lightweight concrete: good insulation all round
If you build your solid house from lightweight concrete, you build either with pumice stones or expanded clay. Both have good thermal insulation, excellent soundproofing and they save energy during their production: lightweight concrete is made from cement and water, and pumice (a natural rock of volcanic origin) or expanded clay (heat-sealed clay balls) are added as a “porous” supplement. They give lightweight concrete its good insulating properties and high compressive strength - and of course its lightness. In the case of lightweight concrete, builders can therefore very well help to build.

Sand-lime brick: Good against noise and temperature peaks
Sand-lime bricks exist in nature, but industrially produced sand-lime bricks are mostly used in solid house construction. Lime, sand and water are used to create blanks that are then hardened under steam pressure and at a temperature of 200 degrees Celsius. Sand-lime brick has proven itself in solid houses due to its numerous good properties: It provides optimal protection against noise, is extremely airtight and therefore pressure-resistant and ensures a pleasant room climate because it balances the temperature. It also offers good fire protection. Its poor insulation values ​​are disadvantageous: today's requirements for thermal insulation can only be met with additional insulation - thanks to the low wall thickness of solid sand-lime brick houses, there is at least enough space for this.

Aerated concrete: massive customization
Aerated concrete contains cement or lime, finely ground quartz sand and water as raw materials. The solid house building material is given volume by aluminum powder. The mixture is hardened by steam at around 200 degrees Celsius. The small pores that are created not only give the aerated concrete its name, but also give it its very good insulating properties. In addition, its low weight and easy processing make it popular with builders. Because the individual aerated concrete blocks can be precisely cut and, due to their low weight, easily placed. This makes them ideal for self-construction.
