Stewie Not any more... I blocked them up on the inside years ago as all the heat was escaping there in winter. Re: Old house with cold double brick walls 8Feb 17, 2020 9:18 am Good idea. Apart from the walls there is not much else you can do seeing as you have the ceiling and floor insulation taken care of. What R rating are they both and did you install them or get someone else to do it? The reason I ask is that I've seen a few jobs in the past where companies have been employed to do it and the end result left a lot to be desired - gaps in insulation between joists, not taken all the way out to the top plate etc. A 5% gap results in 50% less effective insulation.

I got both floor and ceiling insulation professionally done but I can see with the thermal camera that there are gaps here and there in the ceiling.
