I have seen the the typical BFS which involves walls consisting of fabric laminated to FG.  I think the MgO SIPS has many advantages for use in basements, including the inherent water and mold resistance.  For those customers wanting a finished room look, I would think that MgO SIPS, either EPS or XPS cores would be excellent.  I am curious why there is only one dominate player in the industry for basement finishing sytems.  Or maybe it is a fragmented market.  I would think that there are people out there who would like gypsum board walls, but are hestitant to do this in their basement.  Anyone out there interested in discussing this?

Our company reps regular OSB SIPs and now we are testing MgO boards and SIPs. We have built SIP structures on top of insulated concrete form (ICF) walkout basements so that is another option. We will be marketing Mgo in 30-60 days in North America.

It looks like we are advocating the same concept. Where are you located? Are you a stocking distributor?

I agree, the panel would be unbalanced. The best way is to go with a sandwich panel, MgO on both sides.

Of course OSB SIPs are available in lengths to 24' and widths to 8' which results in far greater design flexibility. What are the largest MGO panels that are currently available? 4' x 10'? or 4' x 12'? Also, for consumers, availability is a major factor. How many MGO SIP manufacturers are there in the US and Canada these days? I know that, as of right now, there are no MGO SIPs that are approved for use in California, however that can change when, or if, someone decides to make the investment necessary to gain this approval.

I cannot even get a quote on the board alone in the Tampa area

We have had no problem in finding companies who want to sell us MgO board, but I feel they have done very little to date in developing the SIPS market for MgO.  Basement finishing systems is an example.

We (my principal) www.primepanels.com can laminate the product very successfully to EPS and XPSfoam.  We are trying to identify commercial/residential contractors who are interested in using this type of SIPS panel. 

I also  agree with a previous writer that MgO does have a length limitation compared to OSB.

According to companies who certify SIPs and SIP processes the problem is the ability to certify the MgO. If I buy OSB I receive it with a stamp ensuring a certain manufacturing process and that certain abilities can be assured. These tables are available and the certifying company can then test your panels and assume that as long as the OSB is manufactured the same way the SIP will perform the same way.

To this point no one has been able to provide these types of credentials as the Chinese as less than trustworthy in this area. Anyone can make an MgO SIP, much like a paper mache SIP. Having one you can get an engineer to stamp, well that is a different ball game altogether. Also take a look at the test data for Fiber Cement when compared to OSB. OSB is still the premier SIP skin available...

Greg;

In your axial load testing what is the ultimate load for a 4-1/2" x 4ft. x 12ft wall panel

The ultimate load is based on the faliure rate divided by a safety factor of 3. A good number for the panel you asked about is 2000 plf.

We've being using MGO sips for years in the basement and have also been building additions and homes .

We manufacture in NJ and ship worldwide.

Mgo will replace gypsum in the near future.

Basement refinishing system available in market, but which one is good for use is not very choose. The important thing is that you follow all instructions. If you are not the kind of tinkering, you'll find that working with an OC product will make you look good at all times.

who claim:

The use of Magnesium Oxide cement in the structural insulated panel (SIP) industry was pioneered by MagBoard™. We are the first group in the industry to develop, test, certify and build MagWall™ SIP structures.

MagWall™ panels have been fully tested according to ASTM E-84, E136, E119 and E72 protocols with outstanding results.
