    Polystyrene panel houses

    I read an article in the bangkok post recently about a thai called tanin jobsiri who makes polystyrene panel houses.
    Very energy efficient and surprisingly cheap to build,it seems.The article says that there is a display house in Min Buri built by Homebuilder Centric or is that home builder Centric?
    Can anyone help,where is Min Buri and has anyone heard of the builder or the designer?

    Other than that I could only find the Bangkok News article. It gives location for the house though -Phraya Suren Road in Min Buri.

    I build this "workers house" for test purpose before start to building my main house.
    I buils EPS/MgO sandwich elements- 10 mm MgO boards both side and 80 mm EPS core. In the main house I will use 120 mm elements for subfloors and roof.
    Inside roof I made by EPS panels and also outside I using EPS log siding. I use only painted panels, because local printing shop cant print right colors to my textures...
    Easy to cut any profile and hopely finding place there they can print right way so can made my main house looking like real log house.
    If I find my camera then I will update some photos more(we moved and it be somewhere in the boxes)

    First thought would be fire hazard and what means of fire retardant are used.

    Wiki seems to agree with my suspicions:

    Fire hazards
    Like other organic compounds, polystyrene is flammable. Polystyrene is classified according to DIN4102 as a "B3" product, meaning highly flammable or "Easily Ignited." As a consequence, although it is an efficient insulator at low temperatures, its use is prohibited in any exposed installations in building construction if the material is not flame-retardant.[citation needed] It must be concealed behind drywall, sheet metal, or concrete.[citation needed] Foamed polystyrene plastic materials have been accidentally ignited and caused huge fires and losses, for example at the Düsseldorf International Airport, the Channel tunnel (where polystyrene was inside a railcar that caught fire), and the Browns Ferry Nuclear Power Plant (where fire breached a fire retardant and reached the foamed plastic underneath, inside a firestop that had not been tested and certified in accordance with the final installation).[citation needed]
    Polystyrene - Wikipedia, the free encyclopedia

    What methods of fire retardant are used and how effective are they?

    3 mm MgO board fire rating is same as 13 mm gypsum board and can use like in Finland to get 15 min fire rating.

    Erect the house is easy
    floor take 2,5 h for 3 unprofessional thai workers
    walls 8 h
    roof 6,5 h
    all those times included reparation time for elements.
    Element weight is 22kg/m2 (100 mm element 10mm MgO boards both side and 80 mm EPS core)

    I think totally 12500 THb/ building-m2.
    You save coolin cost and labour cost. Surface is snooth and ready to paint with normal paints.
    I use Polyurea hard coating. It is expensive but the best one also suitable for waterproofing.
    No need to make boxes only imagination is the limit

    In Finland we use lambda value for 400kg/m3 siporex (q-con - that white brick here) 0,13W/m2K and EPS 0,033W/m2K and MgO 0,12W/m2K

    so if use 100 mm MgO sandwich wall it correspond 330 mm siporex wall.
    If put both side panel sidings then it correspond 550 mm q-con wall...
    you get also insulated ceiling/roof same time.

    Does EPS-SE graded (fire retardant) look different from standard EPS? How do you tell the difference...apart from burn and learn?

    I like the idea...but wary of cheap/wrong building material.

    Very interesting, the added extra cost would probably be off set by savings in energy and cut down in the amount of noise from the outside.

    I've seen this method used more and more in the UK. It looks tougher than he panels and would probably be a method that would be picked up easier in Thailand.

    at first I test this too
    but need much more work and irons and concrete and has much lower U value and need thicker walls

    my element have all in one package and strength is enough to build one floor house without any frame and like I make fiberglass I beams c/c 1200 mm jointing elements together can building multiple floor houses. If using earth screws,fiberglass and polyurea whole the house can made iron and concrete free!

    Why use fiberglass I beams?
    4-5 times lighter than iron
    have same strenght as iron
    no need paint
    no rust
    can use normal hand tools to joint

    Just add 2x12,5mm Knauf gypsumboard and it's 60 minutes fire proof, that should be enough to leave the house, granted that you install a fire alarm.
