Keeping Pipe Insulation in place

Depends what you mean by keeping it in place but I used Gaffer Tape on mine. Wrapped it around it so that it couldn't come off along the seam.

I've always used Ty-Wraps (Zip Ties) - the nylon cable ties. Cheap, durable and easy to fix

cable ties are fine as long as you don't crush the pipe insulation.....

Personally, I'd look at aluminium foil wrap tape wrapped in a spiral, that will give a reflective layer on top of the foam insulation so the foil tape will serve two purposes, hold the insulation together and provide a reflector as well.

Tapes fall off in time. It does take longer tying string but it lasts - if kept dry. Under a house, bits of scrap copper wire are one option. Perhaps nylon ties last, I dont know.

Do they no longer sell tape specifically to run along the split in the insulation? That is what I used 20 years ago and it is still in place.

I did mine using unsplit insulation, but that has to be threaded on as the pipework is constructed. (It was semi split, but I didn't break it open.)

It doesn't look like you can buy it anymore for standard plumbing, only for aircon type applications. 12 years ago, Wickes and builders merchants all had it.

Remember the stuff that was like carpet under felt and you had to wrap it round? I do, bloody awful stuff.

That's what I have on the pipes that have insulation.

What's the stuff like? It's in good condition, but is it worth replacing whilst I am at it?

This is what I do, although I just tend to run it down the slit rather than in a spiral.

I honestly do not know how efficient it is. It was over 40 years ago last time I used it.
