Hi,
The picture is of the back wall in my garage, the white painted brick on the left is a single leaf exposed to the outside, the block way is a cavity with the loo on the otherwise.
The cavity is full of rubble and snot and is about 15 to 20mm at it's widest so is too small to insulate (I've drilled holes and looked with a borescope and measured with calipers).
The downstairs loo is very cold, I think what is happening is that the single leaf wall soaking up the cold and passing it down to the outer blockwork of the cavity that in turn is passing the cold through the rubble and snots to the inner leaf to the loo.
If you touch the blockwork and then touch the brickwork you can feel the difference in temperature.
Whats the best way to sort this issue without taking the blockwork down and rebuilding with a proper cavity ?
I don't want to insulate inside the loo as it's already small and insulating the blockwork I don't think would help, it may actually make it worse as the garage gets quite warm with the sun on the door.
Would trying to create a thermal break between the blockwork and bricks be worth while ?
Thanks in advance
