It is produced as perforated or full according to the features it contains. The distance of the holes in the perforated ones from the side walls is called the wall thickness.

• In external walls, these wall thicknesses should be at least 20 mm.

• It should be at least 17 mm on interior walls.

In addition, the volume of the holes should not exceed half the total volume of the hollow block. If this rule is not followed, an efficient result cannot be obtained.

Increasing wall thickness will increase the weight and cost of building materials used for stone. It will increase the load on the structure to be built with stone.

The reduction in wall thickness will reduce the cost and weight.

The usage areas of concrete blocks with different wall thicknesses are different.

For example

Less wall thickness is used in interior walls

• More wall thickness is used in places where thermal insulation is required or on the outer walls of the building.

You can see how much building material will be used and the cost will increase depending on the wall thickness.
