I have recently purchased a 1960s semi detached property which has a total of 11 cavity air bricks.
3 at the front (1 below bay window and 2 level with first floor windows), 5 on the side (3 at just above ground level and 2 just above first floor windows) and finally 3 at the rear (1 below ground floor window and 2 at first floor window level).
There is also a through vent in the lounge for the gas fire
I have noticed the neighbors property, same year built, same size and shape has only 3 air bricks, one on each side at ground level.
He has lived there 14 years and suffered no problems from damp or condensation.
Walking around the estate it seems some of the properties have more airbricks than others.
Firstly is there a need for all 11 airbricks?
I have just had cavity wall insulation installed and so was wondering what the point of having 11 air bricks, my neighbors also has CWI.
I notice in the property drafts under the upstairs floor boards and on a cold night the carpets upstairs very cold from the draft underneath.
I covered 2 of the rear air bricks as a trial with duct tape and the under floorboard draft vanished.
I have since removed the tape and the drafts are back, are there air bricks that will not allow draft into the cavity or can I safely block a few of the air bricks? if so which ones the upper or lower?
