Hello. I am renovating the bathroom/laundry room, hallway, and garage in our 90's Vittjärv house.
Uninsulated slab on ground with floating floor. I have now torn everything down to the slab. I will chip and move some drainage to then lay a new floating floor with the exact same principle. Foam and chipboard.
The unfortunate thing is that now the foam is not 60mm but only 50mm, and the boards are 22 instead of 18mm.
But now to my concern, all interior walls are standing on the foam and the chipboard.
But on the section where I've torn down, I've had to cut the foam and chipboard flush with the kitchen wall.
How should I best connect these two floors for it to be stable?
