Advantages of Cavity Walls

1) As there is no contact between the inner and outer walls there is no possibility of moisture travel ling from the outer leaf to the inner wall.

2) The layer of air in between the walls acts as an insulator and reduces the transferring of heat. Such
walls are most suitable for tropical region, like our country India. It is observed that cavity walls
have 25% more insulating value than solid walls.

3) These walls have good sound insulating properties. These are thus recommended for libraries, radio and T.V. recording rooms.
4) These walls are economical.
