Hi all

Has anyone got any ideas on best materials for pipe packing.
After a central heating re-furb I have some pipes which (at some point of
the heating cycle) clang together.
It seems to occur after the heating has been on for 10-15 mins.
Anyway, I have found the offending pipes and they are rather inaccessible.
I want to fit some material around/between the pipes.
So it needs to be durable, but not abrasive or damaging to the pipe.
Compressible to allow some movement, but resilient so it doesn't simply
flatten.
"Slippy" so that the pipe can move, but not so the material simply falls
out.

It needs to be possible to install this one-handed in hard-to-get at
location where the pipes are fairly hard up under floor boards which cannot
be lifted.

Suggestions gratefully received

Pipe lagging/insulation springs to mind as an obvious solution?

The message

Nip down to Tescos and raid their empty fruit boxes for some bubble-wrap.

Thanks Mathew, but the spacing of the pipes won't accommodate that.
Some gaps between/around pipes are as little as 2-3mm, hence the subject.

If the rads have individual thermostats, check the water flow is in the
right direction 'cos they vibrate like crazy if put in the wrong way round
and rattle the pipes. Some modern valves are bidirectional and might have a
double headed arrow stamped on, in which case that's wouldn't be the
problem.

Just trim the width of the insulation down to, say, 5mm or so and this
will compress nicely into the gap. Such insulation may well prove of
benefit when it comes to the actual fitting as you can put it round the
pipe(s) elsewhere and slide it along into place.

How about some of those plastic pipe clips that are used under trunking
when running radiator pipes up an interior wall? They clip two pipes
together in very close proximity.

Not a serious suggestion I hope?

you can get lagging for that - fibre sleeves.

Otherwise try foam-in-a-can.
