I am building our beach house slowly (budget). I am planning the patio area where I want to build a Pompeii (40" to 48" internal dia) together with a bbq (maybe 48" x 20") and a Tandoor (about 20" dia)
I have not come up with the exact layout yet, but it will also have some counter top (maybe reconstituted granite or large 1200mm x 600mm porcelain tiles). I will probably design it in an 'L' or even 'U' pattern. Room is not an issue. I expect to start building in a couple of months time.
I am a carpenter and joiner by trade but I have laid bricks and hollow blocks in the past.
As my budget is less than 25,000 pesos ($500) I will have to go cheap on some of the materials. I do have some things lying about like hollow blocks, sand, gravel and wood.
I have priced fire bricks here and they are way out of my budget at 100 pesos ($2 each) + delivery for 2x4x8. I am going to use locally made clay bricks from a pottery project. They are 10.5 pesos (21 cents) each for 2x4x8. I understand the up and downs of using kiln fired clay bricks, but in general they seem to be of good quality here. I can get the red clay for free.
Here is where I need advice:
Insulation is a small problem. We do not have much products readily available, probably because the temperature seldom goes below 26C (even at night). We can buy polystyrene but that would melt.
I can however buy Perlite course grade for 750 pesos ($15) for 50 litres. I can also buy Vermiculite 650 pesos ($13) for 5 KG (11LB). Both of these products are available from a hydroponics garden supply store. It seems a bit expensive, but delivery is only about $8.
So for the bottom insulation, what mixture would you recommend for underfloor and between inner and outer domes? (given that I have Perlite, Vermiculite, clay, sand, & cement)
The Tandoor will be made from two pots from the pottery and insulated with perlite.
The BBQ will be brick and my friend will weld up a grate from 304 stainless rod for free.
The tools I will make myself. I can 'turn' the handles and the stainless is lying about.
