or is there any limit?

Have a boiler that the pipes come straight up into the loft - the boiler, in the kitchen, thus allows cold air to come down into the kitchen through the cavity (it's a bungalow) - so I want to just pack the space with loft insulation - thus touching/around the two pipes leading up into the loft space, both of which get pretty hot as you can imagine just to prevent the cold air coming down.

Is this OK to do - the pipes are copper. It seems fine on the plastic pipes we have in the loft, but wanted to make sure copper was also OK?

Thanks

Andy

Can't see a problem with Rockwool, F/glass etc. Mine have foamed plastic "sheaths" on them (it's that stuff sold in metre lengths and slit along it's length, then are buried in Rockwool.

In fact, I'm pretty sure you should insulate them to save money, you only want the heat to escape where it's wanted.......

Andyyes fine .. water pipes do not get hot enough to cause any real probs

Thanks to both of you... thought it was the case but worth checking.
