Hygroscopic mass is one of MGO's worst attributes in humid climates
Most often the boards are produced by using Sorel cement (Magensiumoxychloride).
Resulting in a very hygroscopic product that can produce a problem named "crying boards" when applied in too humid climate.
The chloride also produce a highly corrosive environment for fasteners and steel studs.


Don't be shy write more if you know what you are talking about ;) I can get at least that much from a short goggle search. hahahha!



Proving my point that the truth is close at hand,
but I also speak from first hand experience where the MGO board used in a high end residence in Haiti ( a humid climate)
where the owners continuously experience a acidic-oily residue that leaches from the bottom edge of the MgO board.

and this from a consulting engineers report........."MgO Board’s chloride salts have been blamed for causing some serious corrosion problems in buildings when used as permanent formwork for concrete walls. The chloride salts of MgO Boards only exacerbate the problem "

Chris, you are correct you are not producing ANYTHING on this thread I have not, and resolved by Premier. You state issues no solutions not hard to throw darts I am sure I can find to throw at your designs there are issues with steel don't get me started been at metal design major structural engineering for over 30 yrs.

Innova, I forgot to mention ROMA has a biogrip if Ron has structural rate use it as a brown coat for breathable stucco. It has a very low to no M(microbial)VOC most matls would fail at or are not tested for. Here is my last contact,

Parahomes,
as you say , I am not stating anything that is not available with just a simple google search, it is an open forum, I get darts thrown at me all the time,you need thick skin
the consumer needs to have all the information they can glean from the forum in order to make an informed decision.
That includes the pros and cons of metal, OSB, MgO and fibercement
as a contractor that has used all of those products I speak with first hand knowledge that will hopefully spare someone from repeating the same mistakes I have endured

Chirs, as I stated you don't want me looking at your design if you are a contractor that designed I will rip it apart. This thread is not about steel its about making MAG work so back off!

Here is Jerry's patent you can read solves the leaching and fastener corrosion issues to acceptable levels, and know the paint capabilities of their products. You rarely want to take a contractors word of failure or success over a pros in this case chemist. This info is made public, he has a better solution that is not. https://www.google.com/patents/US8603237 Last we talked he said there are some big players getting behind this. This is the place to be.

I talked to Ron at Foreverboard yesterday and right now they are only manufacturing interior MGO for drywall replacement. The board they are manufacturing is tapered for typical drywall joints. It is exciting that a company is actually manufacturing an MGO board here in the USA. However, this board right now will not work for our SIP panels as we are using the board as exterior structural sheathing and are already using a board that is approved per USA standards and is fully insured against any kind of manufacturing defects. Foreverboard advised that they are working on a external sheathing board and hope to move forward with testing soon. It took Innova 2 years to get the board we are using approved for use here in Florida. We wish Foreverboard the best of luck as It will be a benefit to everyone when more fully approved boards enter the market and are readily available to all building contractors without the stigma caused by the many Alibaba vendors pushing sub-standard boards into the USA market. Most all of the rumors and reported issues are with these boards.

Is there a thread discussing the Steel SIPs? what is laughable about them? It is so confusing for a consumer to decide between OSB MgO Steel SIPS. Most engineers and architects and builder wont even touch or know about these stuff.

Hi doctorman, I'm an owner/builder SIP homeowner. I really feel for you as you try to make sense out of some of this information! I might suggest starting a new thread, describe some of the details of your project needs, your climate, things like that. Send me a PM if you have any questions.

I found this thread to be informative, all of page one and the top of page two especially.

At the 2:40 mark in the video below when the two women pick up the board you can see how much it flexes. I know it's not the exterior grade stuff used on SIP's, and this version is lighter than the stuff out of China, but I found it interesting.

The top video, at the 2:40 mark
