Hi,
We have a 1930s brick semi. At the front, we have a bay (brick). The bay has 4 air bricks in at ground level spaced 58cm, 68cm and 58cm respectively. There is a noticable draft in the front room.
In the side wall where our hall/stairs are there are another 4 air bricks at ground level spaced about 75cm-1m apart. It can get very drafty in there.
Round the rest of the house we only appear to have 2 other air bricks - one is under the kitchen, well below floor level (our back garden is at a much lower level). I find this a little confusing as I am pretty sure that the back half of the kitchen is on concrete as it was extended more recently, so I'm not sure where that vent goes.
The other ground level air brick appears to be ventilation for under the floor in our back room.
My question is whether the air bricks around the front and side seem excessive or whether they are needed eg. for sufficient air flow to the back of the house?
Our neighbour in the other half of the symmetrical semi blocks some of his air bricks with metal plates over the winter (I think about half of them) and removes them in the summer. We've had a new boiler, cavity wall insulation, loft insulation and I've had a look at the hinges and seals on the PVC doors to check for drafts. It seems a shame if we're losing a lot of heat through air bricks if we don't need so many.
