Hello everyone,
In the construction description of our intended house it literally says:
"The base slab will have thermal insulation (bottom slab and edge insulation) of 80mm WLG 035 or equivalent top slab insulation according to the energy certificate."
In our conversation with the contractor, he referred to the top slab insulation as screed insulation and explained that he would install this variant and not the bottom slab insulation. As a reason, he used a comparison to roof insulation, where you would also insulate inside the building to keep the heat inside... therefore, the screed insulation makes more sense. This sounds plausible to a layman at first, but I would like this statement to be critically questioned again – not least to develop my own opinion on it and to be able to discuss the topic...
What speaks for one or the other variant?
Are top slab insulation and screed insulation actually the same?
How would the top slab insulation have to be designed to achieve the same efficiency as the aforementioned bottom slab/edge insulation?
What is more expensive?
I hope you can help me!
Regards, David
