Wall Construction

[furryferret]

Folks. I'm building a two storey house on a budget. Pilings are going in soon and are 200mm square finished so I have to decide the wall structure. I'm thinking along the lines of a sandwich of 150mm Thai cinder blocks with 50mm sheet insulation on the inside, faced with plasterboard. I'm assures that this would give a high R rating and would be cheaper than QCon  or similar. Comments appreciated.

cinder blocks

They are a good way to go, single  75mm ones are used all the time around our way, doubled up is a cheap cavity twin wall build. 

Gone up to 5 baht each now from 4 bht. ?

Yep...your idea will work well...

I am struggling to understand why /or how someone has organized piles without knowing the load/wall construction loading it.

I am also struggling to see how anyone can include budget and piles in the same sentence.

 

good luck tho

With double AAC block you won't need the insulation or plasterboard, it will also go up faster than cinder block and give better sound reduction. So I don't think that it would be that much different in total cost

In Thailand's hot climate you want to keep humidity out of the building with a vapour barrier around the structure.

Ideally with foam under the slab. Insulation goes on the exterior wall, glued onto the concrete.

Concrete absorbs moisture and takes years to dry out when new. The interior should have metal brackets and drywall to allow inward drying of the unfinished concrete walls.

This is assuming you are going to be air condition the entire house. If you are going to have an open system with fans and open vents then it is not needed.

Many buildings in Thailand have mold issues even brand news ones, not sure if this a big concern for you?  What ever you do don't put the septic tank under the building...

I would avoid slab foundations and used raised piers.

To answer you question, the main supports are concrete and reinforce with metal rods, rebar. In between you can use non structural bricks like clay if you like and parge it.
