lagging / insulating multiple pipes

Hello all.

I have a series of copper pipes (water supply + radiators) that are running quite close to each other.... close enough so that I can't quite put pipe lagging around them. So I am using foil backed insulation wrap for these pipes instead. I would like to wrap all the pipes together (not individually) but am not sure this is best thing to do.

However, my concern is condensation - the pipes are obviously carrying a mix of hot and cold water and I am worried that I will have a condesation issue from the cold pipes.... Is this a major problem? Should I wrap the cold pipes separately?

Any help and advice would be much appreciated.

I'd keep them seperate.
More likely get your cold pipes getting hot when heating on.
thank you for your reply... I check what the pipes were for... there are a total of 6 pipes, 3 flows to radiators and 3 returns from raditators.... so no cold water supply as such.... I persume this would be fine?
