Hello,
We are in the process of a complete renovation and are currently at the stage of installing new interior walls for the new layout on our concrete slab.
We have some questions about how to do this in the best way.
- The house is a split-level.
- The concrete slab has minimal insulation underneath, 5mm mineral wool in dry rooms and 10mm in wet rooms under the slab.
- However, as we can discern from drawings and on-site inspections, there is a good capillary breaking layer under the insulation, and it slopes quite well.
- As mentioned, we have completely renovated and found no traces of moisture anywhere.
- We intend to lay grooved foam boards for water-based underfloor heating powered by geothermal energy (Flooré) where we can, and pour screed over the foam boards in wet rooms.
- We will have a moisture barrier before the parquet we will lay (on top of the grooved boards). Tiles will be laid directly on the boards in some cases or on top of the screed.
Since we know that reverse moisture migration can occur if the underfloor heating is turned off and it's not sufficiently insulated, we are keen to protect the new walls in the best possible way.
The builders' plan is to place sill gasket under the new walls which they intend to build with wood.
What does the forum think of this plan?
Should we protect in another way since we plan to lay underfloor heating?
Thanks in advance for all the great tips!
