The Cavity wall usually used for saving heat into home, also if the home has any dampness we can not use cavity wall until solve the dampness problem.

* Cavity walls give better thermal insulation than solid walls. It is because of the space provided between two leaves of cavity walls is full of air and reduces heat transmission into the building from outside.

*Moisture content in the outer atmosphere does not allow to enter because of hollow space between leaves. So, they also prevent dampness.

They also act as good sound insulators.
