Hello,
I have a question:
My house currently has an electric underfloor heating system installed on the ground floor, first floor, and attic in all rooms. I am planning to install a heat pump and retrofit water pipes by milling channels into the screed.
According to the building documentation, there is already insulation beneath the screed. Now I wonder if it makes sense to completely remove the screed on the ground floor, install new impact sound insulation and thermal insulation, and then lay a new screed. The terraced house was built in 1990.
For the first floor and attic, I plan to only mill the water pipes into the existing screed. Would you recommend also removing the screed on the ground floor, or is it sufficient there to just mill the pipes as well?
Best regards

You have WLG 024 6cm (2.4 inches) PUR with aluminum foil facing, and on top a grid membrane.
But aren’t you adding impact sound insulation as well?Yep. But why impact sound insulation? No one lives below you. It’s not needed; the PUR alone is sufficient.N

That's true, there is no one below me. I just thought that once tiles are installed and you walk on them, it might be noisy. But I could be wrong. What you're referring to is impact sound. You won't have any issues with that. You’re welcome to come and test it at my place.

I think impact sound insulation isn’t expensive. It could be installed if it improves things.It could be. But it’s definitely not necessary with the construction method mentioned.
