Heating pipes laid over DPM...will it melt?

[liam546]

I've put a DPM down and wrapped the copper heating pipes in gaffer tape. I hope this isn't a silly question but is there any possibility that the heating pipes will melt the DPM as its only plastic.

No.

Good, thats the response I was hoping for. Many thanks. I'll shall proceed

Offpage, but while you have the bathroom stripped out, why not undercoat and first coat the walls and ceiling?

If you're screeding that floor, consider laying a bit of insulation and underfloor heating pipes now. Don't have to use em but you've then got future potential

Thank you for all the advice

It's only a little downstairs loo so I've decided to lay the DPM, then batton out with 2x1 and put 25mm celotex in between. Then on top will be 18mm WBP ply before priming and tiling.

Does that sound ok?

I have done the below. Battons and celotex. But what about the edges and gaps where the pipes are etc. Should I use expanding foam in all tiny areas and around pipes or just leave it ?

I would like to finish this job tomorrow so if anyone can offer any advice on what to fill in around the copper pipes and walk edges that would be really helpful. I was thinking of just using expanding foam. Them finishing with a vapour control sheet and 18mm WBP ply.
