CAVITY WALLS==>>
A cavity wall or hollow wall is the one which consists of two separate walls,called leaves or skins with a cavity or gap in between.
The two leaves of a cavity may be of equal thickness if it is a non - load bearing wall, or the internal leaf may be thicker than the external leaf, to meet the structural requirements.
Cavity walls are often constructed for giving better thermal insulation to the building...
it also prevents the dampness to enter ans acts as sound insulation . Thus they are normally the outer walls of the building.
SIZE OF CAVITY WALLS==>>
The size of cavity wall varies from 4 to 10 cm ...The inner and outer skins should not be less than 10 cm each (half brick)...
ADVANTAGES OF CAVITY WALLS==>>
=>> External moisture (dampness) cannot travel inside the building..
=>> Transmission of heat from external face to the inside the room is very much reduced..
=>> Cavity walls also offer good insulation against sound...
=>>The nuisance of efflorescence is also very much reduced..
=>> They are cheaper and economical..
=>> Loads on foundation are reduced because of lesser solid thickness...
