Our crappy 1930’s semi just seems to soak up heat, which is handy in the winter, but hellish during the summer. It doesn’t help that our main bedroom where me and my wife sleep’s south facing, with a ******* big bay window. I’ve had the windows and the blinds on the front of the house shut all day, and it’s still 27° in there. Just hope it drops tonight, the outside temperature’s just starting to drop below that now, so once the internal temp exceeds the outside I’ll open the windows and start a fan.
I’m guessing with the age of the property, it’s just all solid brick construction, without a cavity meaning that the brick just soaks up the sun all day, and then radiates it back into the house overnight.
We have a boarded out loft with stairs going up into from the landing. Just at the top of those stairs there’s a Velux window, so I’m contemplating whether somehow adding a temporary extractor fan to that window would help.
