Hello, likely a basic question, but just want to make sure I have it down so we don't make any mistakes!
We are renovating a Victorian property. We will have two windows being replaced - (1)UPVC bay window + (2) existing UPVC opening window being replaced with an alumnium one. And then changing another existing window with a door.
All are in a solid brick wall (so I guess around 220cm wide, approx).
Once our builders have made the openings in the solid brick walls, is there anything else we need to prepare? Do the windows go straight onto the brick, and then we add a bit of insulation internally at the reveals and plaster over? If we did that, I know the frames themselves would be thermally broken so cold from the air wouldn't travel from the outside frame to the inside frame - BUT could cold not travel through the brick from exterior and to the inside frame of the window/door (if the window/door is sitting on the brick), causing a cold internal surface?
Or is there something else to consider, i.e. insulation running the whole length from inside to outside, and then the window sits on that? If so, what sort of insulation would be suitable for both inside and outside in this case.
