The building material is the first element you choose when planning to build your house. In our country where it is part of the heritage, the brick full regained its letters of nobility and today dethrones the concrete block. It must be said that the advantages of this beautiful red brick are extremely numerous and that we have little to reproach him. This is what we will see without delay.
The different types of bricks
There are several kinds of bricks, namely:
- The solid brick or red brick, is a recyclable natural material with many advantages. It is devoid of cells.
- The hollow brick, which has horizontal or vertical perforations, can be used to erect partitions but also walls of load-bearing walls. Lighter than solid brick, and also less expensive, it is the most widely used brick for building houses.
- The facing brick, which is a facade brick. Pressed or molded, reconstituted or in terracotta, it is mainly used to bring a decorative note to a construction.
- The refractory brick, highly resistant to very high temperatures up to 1700 ° C, it is mainly used for the construction of a barbecue, a fireplace or even a pizza oven for example because it is very expensive,
- The glass brick, used inside the house to erect partitions in any type of room, from the bathroom to the living rooms.
Let us focus here on solid brick, a material very present in our landscapes, and recognizable among all because of its red color.
Building your house in solid bricks: the advantages of this natural material
Solid brick is made with a little sand and a lot of clay. This mixture is first dried and then baked at very high temperaturei.e. 1200 ° C. This brick may present some differences from one region to another, both in terms of its appearance and its dimensions. But this does not affect the very many qualities of this brick. In fact, we only know of benefits.
- Offers good fire resistance,
- Has good insulation capacities,
- Let the walls breathe because of its porosity,
- Accumulates heat during the day then releases it,
- Very solid,
- Whose density is 2 tonnes per cubic meter,
- Highly resistant to humidity,
- Offers very good humidity regulation which allows you to benefit from healthy air inside the home,
- Construction material:
- Aesthetic, so that it is not absolutely necessary to cover it with a facade plaster,
- Easy to install.
Solid brick: a material with few disadvantages
The solid terracotta brick can be criticized for displaying a substantial gray energy level, much higher than that of most other building materials – ie 1,200 kWh / m³ – except for reinforced concrete much worse still with 1,850 kWh / m³. It is the entire life cycle of a material that makes it possible to calculate embodied energy, from its design to its recycling. Everything is taken into account: the extraction of the raw material, the transport, the transformation, the manufacture, the marketing, the implementation, the use: these stages require the use of different energies. It is the sum of all these energies that we call gray energy. This allows materials to be compared with each other, at least in this area.
About the raw material price, that of solid brick is significantly higher than that of concrete block. But the comparison should not stop at the purchase price alone. To be fair, when choosing the building material for a house, the cost of insulation must also be taken into account. If we opt for a material with very little insulation, it is therefore necessary to reserve a substantial budget for the insulation of the frame, for example in the case of concrete blocks. However, by opting for solid brick, in fine the cost difference is markedly reduced between these two materials.
For information, the average price of one red brick wall is around 110 € / m² installation understood by a building professional. As for the price applied to build a red brick house, the cost of installation by a pro alone is around € 70 per square meter. This gives us for example all-inclusive € 800 / m² maximum out of water / air out and between 1,500 and 1,800 € / m² for a turnkey house. Obviously, it is necessary request multiple quotes in order to compare the prices according to the desired services, which vary from one craftsman to another.
