The density of the aggregate affects the thermal and sound
insulation qualities of the blocks. Blocks can be used in either leaf (or both
leaves) of a cavity wall. Here, the outer leaf is dense concrete. The wall will
be finished with 2 coats sand/cement render. Insulation is in the form of
cavity boards and a lightweight block inner leaf. Blocks (dense and
lightweight) are also used for internal loadbearing walls and partitions.
Blocks are divided into many types.

| Concrete Blocks |
There are blocks which made from
lightweight, aerated concrete. They form the internal leaf of a cavity wall and
will be finished with plasterboard fixed on plaster dabs. These blocks are also
suitable for plastering.
