Insulation tape to stop creaky central heating pipes?

[HannibalSmith100]

Central heating in my house was retrofitted before we moved in and the pipes creak when heated but also when you stand on the flooring above (still not sure if it's the pipes creaking or the flooring itself). It looks like the pipes haven't been installed low enough into the beams which means they make slight contact in places with the chipboard flooring that sits on top. I've tried to chisel the pipe recesses a bit deeper but the pipes won't drop any lower so I'm thinking of just chiselling a small channel along the underside of the floorboard so contact is no longer made with the pipes.

To help with the creaking when the pipes are heated, I was thinking of sticking electrical/insulating tape to the inside surface of the beam recesses so that the pipes sit on the tape surface rather than the wood itself. Would this stop the creaking and would the tape be able to withstand the heat? Could I also use the tape directly on the copper pipes where there are two pipes right next to each other?

Duct tape would probably be a better idea.And some nail in pipe clips to boot !

if possible, cut the notches a little deeper, then wrap pipes in pipe felt.

Pipe felt like this? https://www.wickes.co.uk/Topsleeve-...uPT7g_qbldeqN4GIkVhoCCscQAvD_BwE&gclsrc=aw.ds

How would the pipe clips help? Not sure what surface I'd be nailing them to?

Nail pipe clips into the bottom of the slot that's cut in the joist. They will keep pipes from rubbing against the side of the slot ,floorboards above ,and any pipe alongside.

Ah I see, that makes sense, thanks. Although I don't think there's room within the recess for this. Could potentially chisel out more room but it's a bit awkward with the pipe in place. Hence why I was thinking more along the lines of a thin tape. I think the felt could work in the space I have though.

If the pipes have rub/clean marks on them where the flooring rubs on them then you need to either lower the pipes or use some 1/2mm hardboard tacked to the joists just to lift the board slightly. Pipes rubbing on flooring will eventually wear through and burst, even with felt applied.

If they are moving due to expansion/contraction and creak or click then don't use felt lagging, it's like a sock that goes over the pipe. Ideally use some (edit) single layer wool felt roll and that will just wrap around the pipe where it sits on the wood.

Great, thank you all!
