Insulation on chased-in pipes

[dwaindigital]

HI Plumbers,
I need some advice on our chased-in pipes. We had plumbers tell us an array of different things.

Questions:
1) Do copper pipes need insulation?
2) if so what type?
3) Do Pex pipes need insulation?
3) if so what type?

I know they have been done already but I'm going to attempt to get them insulation before plastering

I'm worried that the bonding used to fill the chase we rub against the pipe over the years with the heat expansion.


Thanks in advance.

Tbh no insulation as your chases arnt deep enough so either waterproof gaffa tap or hair felt

That's what I thought I needed. I have some of it and just wanted to know if this is the best possible thing to use with the depth of my chases

Single wrap hair felt wil keep the cement off the copper pipes as below . Kop

My neighbor has given me this. Looks similar
Any good?
Will probably cut it into strip and spiral wrap it

Yep very good might need to slit it so you can install it on the pipes

Also hot water and a cloth to wipe the flux off first eg green marks

Thanks,
So much to learn about this stuff.
When you say slit it you mean in sections because of the brackets?

Yes and it’s a tube so slit / cut so you can wrap the pipe eg normally gets installed at the install stage
