Hello everyone,
I have some basic theoretical questions regarding the floor construction. Our project involves the renovation of an existing barn. The exterior sandstone walls will remain and have been reinforced with a foundation, and inside we will remove approximately 40-50 cm (15-20 inches) of soil.
My main question is: at which exact layer is the electrical installation usually planned?
Several years ago, new wooden beams were installed on the first floor, and OSB boards were added on top. How would the construction above this look like (electrical installation/central ventilation/underfloor heating/screed/parquet)? Also, how many centimeters should be roughly planned above the OSB boards? Unfortunately, we don’t have high ceilings, so space is somewhat limited.
I would appreciate any helpful advice.
Best regards,
Daniel

Hi,
I can only tell you how our construction is set up:
From bottom to top: concrete slab, vapor barrier (bitumen membranes), electrical and water pipes, insulation (styrofoam), underfloor heating, screed.
I'm not an expert, but I think it’s not a good idea to have the cables lying directly between the gravel. When it’s compacted, the stones might press through the cable insulation, and then you could have problems. I don’t think the exact position of the cables is critical. I would plan them deep enough so you can route them up into the walls. Otherwise, I would simply run the cables above the moisture barrier and add an extra layer of styrofoam on top (kind of like a puzzle).
I’m also not sure about ventilation. We don’t have any. Overall, the floor build-up on the ground floor is about 18cm (7 inches) and upstairs about 13cm (5 inches) (with less insulation).
