ᐅ Insulating plastic fittings/water pipes and underfloor heating under the screed?

Hello,

as shown in the two photos, the hot and cold water pipes are insulated. The plumber says the fittings (connectors) do not need to be insulated because they are made of plastic. Is this correct, or could this cause problems regarding thermal insulation, condensation, or noise?

The pipes are located under the screed, meaning there will be polystyrene insulation and a self-leveling screed on top.

The plumber suggests he could wrap fleece over them, but says it is not necessary. What is your opinion?

Best regards, Andreas

I would route the conduit over the wall or ceiling. But your solution is rubbish and rubbish again...

No, that’s your approach – so you would chase cut across the structure? Completely against every guideline. You would chase cut into concrete? Totally against the rules...

But thanks, now everyone can see what kind of person you are.

By the way, this is not my solution – I wouldn’t presume to tell my architect and plumber how to do things. And this is basically how it’s done on almost every construction project here – maybe except for timber frame construction, but I’m not sure about that.

I was talking about warping of walls or ceilings, not in *please read first then reply click*.

Why are you talking about cutting concrete in timber construction? No one here will understand that either.

I can’t imagine all your neighbors have companies ready to install the drinking water pipes in the underfloor heating.

Why don’t you write out your floor construction for us ... *I want to keep laughing about construction mistakes

Just read carefully again what I wrote regarding the timber frame...

And interesting how you want to install pipes under a concrete ceiling without chasing grooves.

By the way, no one installs water pipes INSIDE the underfloor heating, but underneath it.

Okay, I’m out, I’m not going to feed a troll like you any further.
