I am sorry to hear this issue as well.

As discussed before, mgo board before, doesn't have a product standard. However, the Chinese government did created a mgo board stand as I posted before.

You need select a supplier that have a good quality management system set up on the standard.

We supplied many containers of fire resistant panels to Dubai and never had a complaint.

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.

One of biggest reasons MGO board interests me is it is unaffected by water. But paper coated would defeat that purpose.

I can buy MGO from China by the container loads, but for some reason I can't buy 50 sheets at any local supply house in the Tampa area. I wonder why that is?
There is however 40,000 sheets of new chinese drywall still warehoused at the port of Tampa they are trying to send back

hello evrybody

i'm sorry about my english

evryone dont tuch this material!!! i bought mgo china, for interior walls, and this board always suprise me to bad, i gone repace all my home to gypsum!!

the first problem- the mgo not stick to light steel construction by screws!

the mgo leak out chlor that cause corozia eat the screws and the construction and its harmful chemical! 

after i paint the wall 4 times ( with 4 differnt method) apear cracks in the connection of boards and the putty fall down!

the mgo cause me big economic damage and i reccomend all of you dont fall down with that material like me

Messi,
Where did you buy the MGO board? Where do you live?

i live in middle east, and i bought it from HUILON GROUP, i buoght also fiber cement boards and this good product,
you know thats problems?

Messi
Where do you live and what application were you using it for! It would seem unnecessary to use this type of board as most buildings are concrete in the ME last I checked or was it an interior wall? Or are using it as part of SIPs? more info if possible.

I have access to MGO board directly from China.  This was used on all Olympic buildings for its safety characteristics: water resistance, mildew resistance, fire resistance and price.  Let me know if you have use for this product, I can arrange shipments directly from China to your destination for any distribution needs.  Limited to container sizes and quantities.  Serious enquiries only!
Regards LJ

perhaps contact info would be inorder?

LJ;

how do we know if it is good MGO or bad MGO? because according to many previous posts there is a problem with unregulated Chinese products

MgO VS Nichiha, Hardi, CertainTeed, or LP Smartside.... I am curious to find someone who has used these Portland based cement products or LP OSB type Smartside and a reputable (tested) (certified) MgO Board. What are your findings? Which do you prefer? Advantages and disadvantages? It seems like many articles I read on MgO.. Users may not be educated on proper installation procedures. Over the past two plus years, I have done a lot of research on MgO board, some crude testing of my own, and spoke to testing labs such as Intertek, and from what I find, MgO is the real deal! Please enlighten me if I am missing something! I have been selling many building products in my 26 year career, and MgO to me appears to be far superior to anything else I have seen for use as backer board, Trim, Int/Ext walls, Soffit, siding, fire rated sheathing and most likely a whole host of other applications. I'm thinking I need to be marketing this product! It is unbelievable! I have tried to grow mold on it, I've soaked it in water for several months, screwed it nailed it, tried to burn it with a blow torch, it is amazing! I realize that quality control, proper testing, and consistency will control the success of these MgO products, but I swear I cannot find anything wrong with the MgO Product. I would not even think of using a Portland based cement product. Or Strand lumber products, if I could be assured that I was able to get a consistent and certified MgO product. I find that Hardi delaminates when it gets wet; it sucks to cut unless you use the snipper device... and you sure do not want to breathe in the dust! A dent in the Strand lumber/OSB type product is trouble for water entering into it and is sure to swell and rot! That is my findings, please tell me yours! Also who has the best MgO? Oh and why don't people identify themselves on this site? Kind of hard to take advice from someone who is unidentifiable?

Mike;

I have used Hardi and Certainteed, I like Nichiha, but it is a little pricey. Vinyl works well for our applications as well. If you take the time to read the old posts you will find a variety of MGO problems and I guess that one of the issues is good versus bad MGO and how does one know the difference?

You are right unpainted hardi will soften when soaked in water. There are many claims for souces of container loads of MGO board, but I can't find one local source to buy just 60 sheets or so for a floor deck, nor can I get any reliable information as to wether MGO reacts when in contact with steel joists.

After the the Chinese drywall fiasco, a builder needs to be extra cautious when it come to Chinese made building products

It seems alot of people are worried about how MgO interacts with other materials.  I cannot speek from experience with the product but I will offer a bit of insight from a chemical insight.  If we consider the metals being use and interacted MgO should not represent any compatibilty problems especially with steel like a few have questionned in this post.  The reason being that magnesium is a much more reactive metal than iron is.  Therefore, a chemical reaction between iron (steel) cannot occur naturally since the chemical bonds that form between magnesium and oxygen are greater than the reactivity reactivity of iron is.

With this, I hope that someone with experience with the product can step up to give real world experience and insight.

Interesting reading.

All products have their place in the market, and market application.
It would seem that some parties here are not looking at the overall picture.

Any board on the market will absorb water and bacteria will grow on any product.
Is there really an advantage to a product will do more or less than the other in this application?

If your basement floods, it doesn't matter what you have on the walls.
It's coming off.

Second is fire.
I've seen a couple of videos out on how fire resistant some of the board on the market is.
That's great.
Fire doesn't kill, smoke does.
When a fire starts in your home.
The only concern at that point in time is the safety of the occupants.
The next concern is how extensive the damage is.
It's not nice to say, but you had better hope that the building burns to the ground before the fire department arrives.
Insurance claims are a bear at the best of times.
The structure will either be ruined from fire; or smoke, heat and water damage.
Either way the the building is a tear down.

Think about it.

Mold and other organisms need food and water to live and exist. If MGO board does not have any organics they cannot feed off it. Gypsum drywall has paper and of course wood sheathing is food for mold.

I was an insurance adjuster for 15yrs, handled only "property" claims. Not all water damage results in the drywall being replaced and rarely would the sheathing be replaced. Rarely does a fire result in "totaled" structure that requires razing.

Gypsum drywall is the worst building product in regular use, it is weak, heavy, mold easily and falls apart with moisture.

I am looking for a non OSB facer approved to span 12 feet in a roof application. Is there a product with or without wood / metal joists in the panel. 10 inch EPS with MGO or Fiber Cement??
