board, it will probably mean you will have to re-install some of the
pipework and making good some of the excess notching.

I believe building regs require you to insulate pretty well all water
pipes nowadays, for economy reasons rather then frost protection.Â* This
does not adversely affect your second suggestion though.

Although I have insulated my pipes, I'd not be too worried about not
insulating central heating pipes upstairs - any heat lost will be
lost into the building.


Wrapping the pipes can prevent them rubbing against the joists and
hence creaking. I would strongly recommend doing it.

If it is purely for noise, then simply wrapping at the joist will do that.

As I said, I have insulated my pipes, but only between the joists. Where
they pass through existing notches, there is just a very thin layer of
material to keep them from touching.

If you only do the bit where a pipe goes through a notch, expansion and
contraction of a number of years might 'relocate' it.

The slip-over felt-style insulation is cheap enough, surely ?.
