Is anyone using Magnesium Oxide Board in place of OSB. I heard it was stronger, more water resistant and cheaper considering less finish work needed.

David,
I logged a story in my photo blog on a company in Edmonton Alberta that is importing panels from China.
Try doing a Google search or look at my blog for more info. magnesium oxide dose not like getting wet then
freezing but if sheltered seems to be an excellent alternative cement board.

David,
Magnesium oxide is a great alternative to OSB, plywood, gypsum board, and tile backer board. It is water resistant, mold/mldew resistant and fire resistant. If you need information about people who have used magnesium oxide board, please let me know.

| Just use Georgia Pacific Densglass Silver or Gold Sheathing. It works better than OSB or plywood. It's easily obtained everywhere and so the cost is down also. There's also a company here in Canada that uses a composite resin of waste plasitcs and wood fiber (plastic wood?). |

I have spoken with reps form several companies about using this product here at Villa Lagoon which is a Gulf Coast hurricane proof waterfront house. I feel sure that we will use this product for walls and ceilings but don't know from whom yet. I suggested to several of them that they form an alliance to promote and educate.
I have made a web page that lists all the suppliers that I have found and links to their sites:

Magnesium Oxide Wall and Ceiling Material Suppliers
Follow along on our construction journal to see what brand we use and how it goes for us. You can also see storm photos on our site that show why we will not use gypsum board.

Ya'll better watch out, when is blows over, Dick Mills might call you a liar!
Man shouldn't put GOD to the test by such statements

Yea, I agree, hurricane proof is a strong statement, but hey...it is also a statement of optimism (sp?) as I see it.
Since Hurricane IVAN's eye went directly over my house and we suffered no damage...didnt even loose the roof ( I researched that before making my roofing decisions) ...while my yard was full of about 3 or 4 other people's houses all broken into pieces...took 3 days of back-hoe work to get the debris to the street in piles....I am thinking that this place of mine is hurricane proof as far as any storm dished out so far.
Even w/ all the windows locked, and shuttered, inside from the force of IVAN, [b]my big Venetian glass chandelier[/b] spun with such force that all the topmost decorative glass flourishes were slung all to one side. I have left them like that as reminder of the force of the air pressure changes. Hurricanes have lots of mini-tornadoes around the eye.
Inside I used no sheetrock, only tongue-in-groove boards for wall s and ceilings. Concrete floor and Weathershield windows and doors that open OUT, so the force closes them tighter.
The hurricane broke off all the J&L Dade County rated shutters on the south side and I never saw them again (goodbye 7 grand)...but the DAC-ART walls and the seacoast upgrade Weathershield windows held strong and tight.
After IVAN, Pensacola TV came over and did a special about my place as it was in such contrast to the devastation all around us. The water level was half-way up the length of my floor to ceiling windows but we only took in one half inch...that was from the dryer vent that I forgot to plug w/ a plumber's pressure test expansion plug. It was under the water level.
This stuff I have built with is some strong-ass stuff :o)
BTW--a sample of Dragonboard MgO board came in the mail today. If you tap it on your teeth, it feels like porcleain. It is totally white, looks like the inside of an albino Kit-Kat bar and is very strong. I am sure that this will become the standard for building down here for anyone with any sense....gypsum board is for idiots in a hurricane zone, IMHO.
I do not know why this snap-shots code (below) is inserting iteslf, it is not on my screen even in the edit panel. It is a search helper application we were experimenting w/ as a web page creation tool add-on to thumbnails the other day...guess I had better do an uninstall.

Concrete cottage;
Hate to be a "doubting Thomas", but do you have any pictures of the waterline halfway up the floor to ceiling?
That would mean the windows were at least 4ft. below water?
It's hard to believe that with the storm surge and hydraulic pressure exerted upon the windows , that your house was a reverse aquarium.
It would mean that ; not only were the windows water proof, but the attachment to the structure was waterproof as well. |

It looks like Hardie isn't too keen on the idea of Magnesium Oxide sheets competing with their products.
AC386-1007-R1—Fiber-reinforced Magnesium-oxide-based Sheets. A new criteria is proposed for fiber-reinforced magnesium-oxide-based sheets with various end uses. click here for responses
Here is the proposal: ac386
And, to be fair, Magnesium Oxychloride cements are very strong, but if they get wet the Magnesium Chlroide can leach out of them which degrades the integrity of the cement. Not to mention that magnesium chloride salts are very corrosive to metal that comes in contact with the salt.

According to concrete cottage ....
"I am sure that this (Magnesium Oxide Board) will become the standard for building down here for anyone with any sense....gypsum board is for idiots in a hurricane zone.
and according to DM it doesn't fair so well when wet,
I am still waiting for CC's photos with the waterline 1/2 up the wall, it looks like it was an attempt to promote his website , rather than a valid claim |

I am pretty sure that we will go with Magnum Board from www.magnumbp.com . Dan Armstrong of Magnum Building Products has been very helpful. He's regional to us and that helps.
Two of the suppliers have taken pieces of their wallboard and run a rope thru a hole in it and left them submerged for months. They pull them up out of the lake every so often and do some on-the-spot primitive hardness tests, etc...and at least visually, cant see any change in the product.
I am not too concerned here with possible leaching of Magnesium Ch if that happens, cause for one, I wont have much, if any metal below the wallboard and if there is THAT much water...the salt alone would be corrosive enuf, plus , and that much water will be washing stuff to ground level anyway. If I were using steel studs, that might be different.

Go to the "Rules, Instructions and Announcements" forum, there is a section there about uploading photos.

| Is there a company that produces SIPs with magnesium Oxide Board? Can someone answer the discrepency about wet and leaching and waterproof - conflicting information. What about in places that have a significant amount of seasonal rain year round like the Pacific Northwest? Is leaching and soil contamination a potential problem? Is there a significant cost difference between OBS and MOB? |

| Thanks so much - I'll call next week. Our build is not for another couple of years, but I want to make sure I have all the necessary information before I lay my money down on the last home. I know that we'll going to build an sip home, and, right now, learning about the various types of skin possibilities and which will be best for our home and its specific climate is one of my projects. |

The 3/4" product can be used in a flooring system and will replace 2 1/2" of concrete
If I put down 3/4" Magnesium Oxide board on my joists and fasten them do I have a structural subfloor?
Another question - could I use it to replace OSB or plywood as structural sheathing on a roof?

Our lab is presently testing MgO SIPs. At this time we are testing adhesive spread rates for SIPs with an EPS core and MgO skins on one and both sides of the SIP. I mention one side and both sides since we are also evaluating SIPs with different skins, such as OSB/MgO, Fiber Cement (FC)/MgO, and OSB/FC. We have not started compressive load or rack/shear testing because we are not through assessing adhesive spread rates.
We have reviewed reports on MgO skins with internal steel (C channel) studs from a MgO supplier; however, this information, while interesting, is not the same as traditional SIPs with an adhesive bond to an EPS core; and therefore, of little value to SIP manufactures. I am not aware of any ICC or other code reports for MgO; although, it would seem reasonable that manufactures would be pursuing those types of testing. Those interested in this on going testing and information may contact me off line at:

Your information, while interesting, dose not provide us any new information. It is nice to see that a manufacture knows their product; however, we need information on how to build SIPs from MgO and performance data on SIPs with MgO skins. Most professionals tend to discount manufactures claims unless they are accompanied with engineering data or certifications such as ICC. In searching the ICC data base, I find they do not have any certifications for MgO in any form.
If you have engineering data such as the modules of elasticity, bending moment, compressive, tensile, or shear strength on your MgO skins, please share this information with us.
Thank you,
