Citizens! My searches on the subject turned up a few threads, but they were all kind of old, so I hope no one minds me asking again if anyone here has any experience with MGO board. I'm specifically interested in anyone who might have used it for subfloor decking or roof decking for ICF structures. I'm about to commence building what I'm pretty sure is going to be, the bank willing, a two-story Reddi-Wall house this summer. I'm most interested in this material due to it's not being (fire)wood. But the more I look into it, the more I see the potential for MGO board to be an excellent fit with ICF construction. For instance, there have been threads here concerning the practice of using certain floor joist hangars to hang floors without removing the EPS from behind it, technically creating a potential fire chase that would allow spread between floors. However an interior envelope made with MGO subfloors with MGO drywall butted up to it and an MGO board ceiling could moot the issue by creating a seamless firewall between the habitable interior and the ICF. But at this point of course my ideas are all purely conjecture, so I'm hoping to hear from someone with experience with the product, which is why I'm posting. By the way, how about this idea: steel trussed floors with 3/4-1" MGO board topped with a half inch or so of non-structural GypCrete as an inexpensive substitute for a poured concrete floor? Light, fire-proof, water-proof, sound-attenuating... can't beat it with a stick! Or can you? yours/ peter.

I have heard of Dragonboard before but I am not sure about the availability in all regions of the country. Geopolymer products are a fine choice for building your house. Not a lot of people are aware of the product, there benefits, costs etc. It is considered a green building product due to the low energy required to produce it and no CO2 emissions during production. It definetly would help in gaining LEED points.

I have never seen this product in any lumbertyard, Lowes or Home Depot. So I am not sure how you would get it - and you are right, it is an excellent product to augment ICF's.

Another product on the same wave length is GigaCrete. Again its availability is questionable in your region. I know everything can be trucked but these days you also have to look at the cost/benefit equation when considering transportation expenses.
