can we insulate our bathroom's cavity wall?

[janek]

we have a victorian/edwardian 2 up 2 down with no cavity wall. however, the bathroom (downstairs, out the back, past the kitchen) is an extension and does have a cavity wall (or at least i presume it does - the brickwork is different and looks like a cavity wall insulation leaflet that came through the door once...).

so, is it possible to insulate just a bathroom? would a company come out and do just that do you think? have you done it? it's so cold in there, even with the heating on, and the condensation on the walls implies that insulation would be the key...

Hi janek - first of all, you have to determine that you have a cavity to insulate. If your extension was built after about 1950, then it probably has a cavity wall. Another giveaway is the brickwork - if it is "stretcher bond" - ie you can see the "long" part of the brick laid end-to-end and then another course of the same bricks laid on top of that, with no "short" parts of the bricks visible, then it is probably a cavity wall. If so, yes, it can be insulated, separate from the rest of the house, and yes, it would make a difference. Hope this helps.
