Has anybody used these concrete planks in the construction of a single story house, to go above a regular suspended plasterboard ceiling in the roofspace.
I ask for these reasons.
1. It would create a proper attic environment for storage space if an access hole (lockable) was installed.
2. They would be another barrier to lessen heat transfer from rooftile to rooms below. (obviously insualtion would be laid on top of the beams).
3. Most important reason. Security. Many burglars in Thailand remove a few roof tiles and get in that way. Those concrete slabs would be a real disappointment for them!
4. The "cold" water storage tank (and maybe the pump?) could be located in there, considering it gets bloody hot in there, it might supply nice warm water for free.
5. There would be some benefit for sound proofing.
Feasable?
Cost per square meter for those beams?
