Just finishing off the first fix plumbing in my new bathroom (upstairs)
and I'm turning my attention to insulating the new pipework before I put
the floor down (chipboard over the kitchen ceiling). I'm insulating
both hot and cold, to help stop condensation in the case of the cold,
but it worries me I have a cold bridge where the pipe passes through the
hole in the joist. Has anybody had any problems with this, and even
better, could offer a solution please?

Thanks.
