Wonderful work but a bit outside the scope of this amateur as I've never carved a stone.
The Cheongmaru really does look nice. I wonder how it can be done with much less vertical space like what I have in this room? Or what would be the best practice for putting in a wood floor in this room?
Yes, you are right that material is some type of vinyl. I was thinking of getting rid of it but if it serves a purpose there I might as well leave it.
When you say '500 mm on center' does that mean to space the furring 500mm apart, with one of the furrings starting in the center?
In regard to the joists, how are they joined to the floor, or do they just rest on the isoplaat?
If you look in my diagram, I have run the joists in the opposite direction of the furrings - is that correct? And what sort of spacing should they be placed?
Is the furring there to create an air gap between the reflective insulator layer and the isoplaat?
Finally, with the reflective insulation - would you normally use this material if it wasn't a concrete floor we were working with?
Say it was limecrete or cob - would you still use a non-breathing reflective layer in there?
Anything else you could suggest would be a great help!
