The interior perforations make it possible to produce lighter pieces and, depending on their geometry and composition, they can improve the wall’s thermal performance. There are also different sizes and configurations intended for interior walls, exterior walls, and other uses.
Another advantage is that its lower weight can help reduce the permanent loads of certain elements of the building. Even so, not all hollow bricks have the same characteristics, so it is important to review the technical specifications of each piece.
Which is more resistant?
Resistance should not be determined solely by whether the brick is solid or hollow. The performance of a wall also depends on the type of piece, its specific strength, the mortar, the arrangement of the bricks, and especially the structural system of the building.
In a modern home, for example, a brick wall can function as an enclosure without being the element responsible for bearing the main structural loads. In other systems, masonry can have a structural function and require materials specifically designed and calculated for that purpose.
For this reason, before choosing a brick for a load-bearing wall, it is essential to have the calculation and specification of a professional.
Which insulates better from cold and heat?
In terms of thermal insulation, hollow brick may offer advantages thanks to the air chambers inside it. However, that does not mean that any hollow brick is automatically a better insulator than any solid brick.
The thermal performance of a wall depends on the whole assembly made up of the brick, plaster, cladding, air chambers, and insulating materials. The wall thickness and the proper execution of the work also have an important influence.
That is why, if the main goal is to keep a home cool in summer and warm in winter, specialists usually consider the complete insulation system rather than choosing only between solid and hollow brick.
Which brick do the experts recommend?
For a conventional construction, hollow brick is usually a practical alternative for many enclosures, mainly because of its lower weight, ease of installation, and insulation possibilities.
Solid brick, for its part, remains a useful option when certain strength, mass, or durability performance is sought and when the project specifically contemplates its use.
