Hi all,
We have lived in this house for coming on 4 years and have never understood why the extension to the house is always a lot colder than the rest of the house. The extension consists of a garage that backs onto a office room and partly above the office and garage is the master bed room (ground floor bigger than 1st floor).
I have been doing some cabling today (RJ45) and needed to pass a cable through the garage into the office. I removed some breeze blocks that were at the base of the connecting wall. They were not physically held in place and just wedged in there. I was surprised to find the setup as per the attached picture (sorry, hand drawn by an accountant so hopefully makes sense).
I can fully understand why both the office and the bedroom get so cold as there is nothing stopping the cold air going up the cavity between the garage and the office and then subsequently into the floor boards of the upstairs bedroom.
Is this usual to have such a setup? I guess the problem is because the garage floor is a good foot lower than the house floor and so although there is installation in the wall, there is nothing stopping the cold air going under the insulation and into the gap. The wall does almost seem like it is floating.
Now how would you address this? I am thinking about using just loft attic insulation and wedging like a foot or so up the cavity all along the wall. I would let this hangdown to the garage floor and then refit the breeze blocks and seal around them. Do you think that would make it better? Is there another better solution for this? I was tempted to just blast a couple of cans of expanding foam up there but concluded this probably would be very wise.
Any help would be appreciated.
