Hello,
My semi det. house built circa 1945 has terrible draught running around the cavity walls. My sons room is very cold and the other day I noticed that cold air was coming out from the skirting board. This was coinciding with the gusts of wind i could hear outside. Downstairs in the living room, a slight hole under the window board was also letting a howling gail through. I intend to block up both of these holes, but i am worried that there is such a draught inside the cavity wall in the first place.
I do know that previous owner has had cavity wall insulation fitted. I have seen evidence of this, when the windows were replaced (didnt see every window being replaced). I remember in my sons room, there was quite a deficite under his window, so i stuffed some loft insulation in.
All 3 bedrooms and corrosponding rooms downstairs have had fire places when house was built. most of these are gone now. But i think i might have worked out where the draught is getting in to the cavity wall.
On the external wall of my sons room near the eves, there is a 12" square air brick with large holes. This is facing the direction of the wind and must be letting in the draught. I do remember seeing the corrosponding louvred vent in my sonse room has been filled (when i wallpapered).
I have two more of these air bricks on the bathroom and toilette, but the room is not as cold / draughty.
I was considering blocking it up somehow, but noticed that all the other houses in the street still have the air brick in place.
Any ideas regarding what I can do about the draught inside the cav wal and if it would be a good idea to block the air brick up. More importantly, how? (I was thinking expanding foam / sand flat / paint red).
Please help our house is so cold!
(to prevent the usual pointless posts, have new boiler, working CH, double loft insulation).
