Replace radiator microbore with 15mm copper pipes behind skirting board

[germproof1206]

Hello,

I'm replacing the copper microbore pipe currently running through the concrete slab with 15mm copper pipe behind the skirting board.
As per the picture bellow, I'm removing about 12cm of plasterboard and planning fix the pipes directly to the brick (cavity wall) with plastic talon clips.

I read a number of threads where people seem to be performing this work with no obvious concerns.
Are there best practices I should be following, like insulating the pipe or running tape/membrane between the wall and the pipes ?

Thank you

The ideal would be a bit of rockwool/felt or similar just to lag the pipework but it's not essential.
