Cavity Wall Structure

Mullie

Can anyone clarify something for me regarding the construction of the walls in modernhouses:
How exactly is a cavity wall built?
According to the info I've searched on the web, going from the inside to the outside a wall is structured as follows:
Plasterboard
4 inch block
Insulation
Cavity
Outside block

This image also corresponds to that general description.


If I'm not mistaken, in my house, starting on the inside:
Plasterboard
Large Cavity
....other stuff that I can't see.

My problem is that there is a gale blowing through this cavity that enters the house at the base of the wall below the skirting boards/under the wardrobes/on the underside of the window sills/plug sockets and generally anywhere that there is a gap.
Is this normal building practice?
Is there something wrong with my walls in the fact that there is free airflow immediately behind the plasterboard?
Thanks!

very few houses are actually built as described. You need to figure the exact construction.
Is the plasterboard stuck to the walls with dabs of plaster ?

A very common problem can be the 4 inch pipe used as a vent is short of the plasterboard allowing air in behind the board at coming out at the skirting. solution is to extend the pipe.
