DIY Doctor has been spending time re-writing some of our projects and the one on air bricks has been republished with lots more information including what air bricks are for, and why you should look after your air bricks to make sure they are providing enough ventilation.
Below are some of the questions we deal with in this new project A Guide to Air Brick Installation and Maintenance to Prevent Condensation and Dry Rot to Timber Floors

You will need to fit an air duct to ensure the air travels straight under the floor from outside and doesn’t disappear into the cavity wall. These are special telescopic ducts you can fit, to make sure you get proper ventilation and avoid problems with your floor timbers. . .
