Pipes filling!

stebiz

Can I ask what anybody uses to fill holes in which house pipes that maybe an inch or two. In the past I've cut up an old cloth etc to stuff in but I'd like to do it properly and paint over.

Foam?
Polystyrene?

I'm guessing with some pipes getting hot it will need to be heat resistant.

Do you mean you've got a pipe going through a wall, and the hole in the wall is larger than the pipe ? If so, the easiest is to buy a can of the expanding foam, this can be cut / sanded once it's cured. Or else you could just mix up a small amount of mortar and use that to fill the gap - if using mortar, it's a good idea to wrap a bit of lagging around the pipe first, to prevent the mortar coming into direct contact with the pipe and causing any problems later on. Sometimes mortar can "attack" copper and cause a leak over a few years.

Yes that's what I mean. Not worded very well by me. I was thinking foam. That's okay with heat??It's just to save any drafts. Also around waste pipe etc which obviously won't get hot.

It's supposed to be OK with heat, at least the amount of heat you'd get from a pipe. To be honest I'd be tempted to wrap a bit of lagging around the pipe first, just to be on the safe side, but then I'm always a bit over cautious :-)

Maybe not the appearance that you are after but you can buy pipe collars which are neat and very cheap.
