House made of expanded clay – thermoactivity in action

Expanded clay houses have already gained immense popularity all over the world. Why?

When choosing materials for building a house, almost every one of us is guided by the same criteria: material strength, thermal insulation, durability, price. But what is most important today?

If we structure the answers of the average buyer of building materials, we can highlight the main points:

Durability – you always want to feel safe in your own home and think about repairs as rarely as possible.

Healthy microclimate – a private house is a long-term investment. Most likely, your children and possibly grandchildren will live in it. It is clear that a healthy atmosphere should reign here.

Thermal insulation - as we know, it is heating that represents the largest part of operating costs.

Having analyzed the most popular building materials from the point of view of the above criteria, we can confidently state that expanded clay blocks are the best fit for all these requirements. So…

Durability - expanded clay this material is made of clay and its durability can be compared to ceramics. For information - in Europe, medieval ceramic buildings built in the fourteenth century are still in use in some places.

Healthy microclimate - clay, as a raw material for the production of expanded clay, is a natural, "healthy" material. In addition, due to the structural features of expanded clay, "breathing" walls can be erected. This material also has the highest vapor permeability, which will not allow mold and mildew to develop.

Thermal insulation - expanded clay blocks have very low thermal conductivity. These indicators allow using a thermal insulation layer at least 2 cm thinner than in the case of insulating walls from other building materials.

This means that for 172 sq. m of external walls you will get on average 3.5 m³ less thermal insulation. But this is only one aspect of "thermally active" walls. Secondly, the already mentioned vapor permeability is very important. During the operation of the building (when taking a bath and shower, washing, cooking), water vapor constantly "tries" to cross the wall. If the vapor accumulates in the room and walls, this creates ideal conditions for the development of fungus and mold. Expanded clay walls are "breathable", which allows them to effectively remove water vapor from the house.
