    It does but the "standard" here is 1/4" vs 1/2" in the US. 1/4" is just too thin to hold up and of course 1/2" costs more.

    Good info. It is just something I don't ever recall seeing in the Philippines (or Asia). Maybe I just wasn't looking hard enough.

    I don't like to say this Barry but: I must say I would question the construction techniques here, especially the pillars; not that I am saying I am an expert far from it, but have read enough about it and have some understanding of concrete construction, that I can see some errors here.
    No way should a HB wall butt up to the rebar cage, all rebar must have at least 40m of encapsulation all the way round, hard to tell exactly from the picture, but I guess a half form will be placed over the cage each side and then the concrete dropped in from the top, it is not possible for it to get a firm grip on the inside rebar on the outer edge, also the HB wall will soak up the water out of the concrete like a wick, this further detracts from proper concrete construction added to all that; the likely small area of cross section of the pillar will render it not fit for purpose.
    In a pillar and beam construction all vertical pillars should be constructed up to the first beam in one continuous pour and every 40mm there should be rebar projecting out the sides to then tie in to the HB wall which is formed after the pillars.

    Just some general comments from reading responses to the OP, not critiquing his construction. With the beam and column construction the hollow blocks are really "filler" not structural. If you are using block as a structural component without beams as roof support I would have some concerns with the "average" block here, even with rebar and concrete fill (most are filled with mortar unfortunately) and the render are not enough to be structural.

    As block is normally just a filler I would recommend using EVG panels. They are faster to install and give some thermal and acoustic properties with the Styrofoam. Super simple to install utilities and it all gets rendered anyways.

    Standard construction with concrete and beam construction is usually to do the beams and columns first and then the block. I can see a slight benefit to doing your block first as you can use the block as your formwork. As mentioned earlier by another, you need 2" around your rebar cage for the concrete. Also, you need to "tie" the block to your columns with rebar or that wall is basically sitting there not tied to anything.

    With a house constructed with concrete there is little need for sheetrock; I guess if you want to fur out and insulate but see no true benefit for doing so when you look at thermal mass of concrete. Again, using the EVG panels would be about the same insulation value without the extra work and cost.

    For ceilings I would not use marine grade plywood. For what folks have mentioned with termites plus the fact that finishing it never seems to work well for the houses I've seen. Our house is two floors so I just went with the concrete deck that was rendered for the first floor. I did use hardiflex and tile for the master shower and it has held up quite well. I used hardiflex for the 2nd floor ceiling, the area is wide open to the elements. It was finished with joint tape and joint compound the same as you would finish a sheetrock ceiling. Hardiflex or the other type of cement board does take a bit more to install with even a 1/4" board is heavy but really worth the effort in my opinion because it will last much longer.

    Wood cabinets, trim, doors, etc. should be treated for termites; I have not noticed any discoloration when you finish the wood; paint, stain or varnish.

    Just my experience and thoughts.

    Shawn where are the EVG panels available. I am going to build a house in the future and would like to find out more about them (i.e. price, installation instructions, where to purchase).

    Shawn has given some detail on DI about his house build using the EVG panels he also mention where to get them in Cebu, as for the details on the construction method here is a site to check out; http://www.tridipanel.com/PDF/assembly_manual_tridi.pdf, also there are many you tube videos showing the basic principle of installation, the only one thing there is little mention of is the application of the mortar by hand.
    Shawn has said before that when he used these panels he had to apply the mortar render 4 times to get the required build up, there is mention of a hand tool to apply the mortar on the above site but I never did find it anywhere on the net?
    I would be confident to build a house without pillars or beams using EVG panels, the whole point of using them is their insulation value, pillars and beams detract from that somewhat but may be required when additional floors are added.
    It would be good if Shawn could give us a little more info on the application and the consistency of the mortar required to finish them?

    Having given more thought to the issue of using Pillar and Beam construction in conjunction with EVG panels, I see no reason not to use the panel material to create forms for the Pillars, perhaps even easier to use than Plywood, that way you have insulated the Pillars and no wasted wood, maybe someone has some scrap EVG material and could make a small test piece? Not a bad idea I think?

    As mentioned, I did a lengthy post years ago just on EVG panels, should be pretty easy to find. I really like them and the time/cost savings over block is well worth it in my opinion. Any future builds will be either poured concrete or EVG panels with the beam/column construction.

    If you have any specific questions or interested in some "lessons learned" using them just let me know. More than happy to help, especially if it saves folks time/money on their own house build.

    We would loved to have used EVG on this project but as my builder's guys were not familiar with it we decided to play it safe. But I agree wholeheartedly with Shawn - I would far prefer to use them in any future job. I have lived in a place built with that material and the insulation properties are fantastic!
