I have a single-story house with a basement, built in 1968. I've been considering insulating the basement floor. From what I understand, they didn't insulate under the slab back then. Now it's the first winter in this house and we've noticed a significant temperature difference in the floors in some rooms.
In the family room, we have a raised floor that will be replaced with a ventilated floor after the turn of the year. In the changing room before the sauna, there are heating coils in the concrete.
In other rooms, marked with orange color, the floors are not warm but also not as freezing as in the room marked with blue color.
In the technical description from 1967, it says the following
Could it be that the floors are partially insulated underneath? If so, with what? Is there any other explanation?
We live in a house of the same age, also with a basement. However, ours is a Gullringshus.
What kind of heating system do you have?
We have a waterborne single-pipe system (in two loops) where the pipes go through the basement floor. Therefore, we have underfloor heating in some areas and cold in others.
In the places where I have removed the slab (during the replacement of floor drains), there has been no insulation underneath. Just thick plastic, directly on the gravel.

In places where I've removed the slab (when replacing floor drains), there has been no insulation underneath. Just thick plastic, directly on top of the gravel.
We have a waterborne system with radiators in all rooms. In the changing room before the sauna, the pipes have been routed down into the slab but nowhere else.
We have a hydronic system with radiators in all rooms. In the dressing room before the sauna, the pipes have been run down into the slab but nowhere else.
What is the easiest way to run the pipes down into the concrete? Attach a plastic tube tightly back and forth over the entire floor and mix cement to raise the floor up then? And tiles on top of that afterwards...?
