Magnesium Oxide Structural Insulated Panels (MGO SIP) as manufactured by Innova Eco Building System in Miami Florida are Dade County approved for use in the coastal high impact 180 mph wind zone, NOA #14-1202.06.

I see your SIPs all have plywood or OSB on the outside of the wall. Why is it that the MgO board is only on the interior? I would think in terms of termites and overall durability it would be preferred to have the MgO to the exterior. Does the MgO not hold up to the wind loads? I would be concerned about warping due to different expansion of the two different skin materials.

The Innova Dade County SIP wall panel does not have OSB on one side of the wall? They are MGO skins on both sides of the wall panel. We do manufacture roof panels that are manufactured with a top skin of OSB, plywood or MGO per customer requirements. The MGO Bottom skin used on the roof panel types by Innova eliminates most all creep which is a common issue in wood frame construction.

The 8" MGO roof panels supplied by Innova for a simple gable roof had MGO on the underside and PT plywood on top. They bowed noticeably at a 10' span. That may be because the skin joints of the panels they supplied were not staggered as specified by Innova's own engineer.

It should also be noted that to achieve the 180 mph rating a lot of lumber framing is required (in my case 3 boards of 2x8 lumber nailed together arranged like a rafter between every roof panel.) Also 2 or 3 sistered studs 2x6 between most wall panels. The studs have to be fastened to the bottom plate with Simpson brackets on both sides. There is a problem with access to the buried side of the joist, requiring the SIP to be cut or notched and then repaired. The triple top plate has to be beveled and screwed or spiked to the joists. In my opinion this is a very clumsy solution to achieve a hurricane-rating.

InnovaPanel,Product approved for all Florida Wind Zones including the Dade County Coastal Impact Zone of 180 mph winds. MGO Sips will not mold or rott, not affected by termites and you can finish the board similar to drywall. "Build the Home of the Future Today with energy efficient InnovaPanels!"

In response to vh2q........This would not have happened if you would have used Steel SIPs.

I have installed Steel SIPs and they are great product for industrial warehouses and uses where the steel panel is the intended final building finish. On homes, if you do not want that industrial look of a steel panel on your home you have to install siding or wire lath and stucco for the exterior and you have to install drywall on the interior, more time and cost to the project. The InnovaPanel can be taped, finished and painted similar to drywall without the added cost of siding and drywall.

The InnovaPanel is a Patented MGO SIP panel that can be used on a steel or concrete structure for an energy efficient building envelope. Innova's MGO SIPs are tested for 200 mph wind loads and are product approved for all regions of Florida. MGO SIP's will not mold, rot and is not affected by termites.

do you mean industrial like this one ......
or this one

or this .............

Yes, exactly like those homes. Look at the $ that went into applying a stucco finsih and paint on a metal panel. Look at all the spider cracking in the stucco before the paint was applied. With the MGO panel, just patch the joints with butter grade and paint for a smooth stucco finish; plywood sheathing and wire lath is not required, a big savings to the project Owner. Again, I have used metal SIPs for commercial projects with good results. Every product has its sweet spot and the MGO SIP can be painted inside and out for a traditional look without the added cost of siding and drywall. If you want a textured stucco finish, we use an elastomeric product that is replacing traditional stucco finishes on High Rise projects. These products will not crack and outperforms traditional stucco which tends to crack. The attached images show the application of a textured stucco finish to our panels. javascript:amaf_insertHTML('');amaf_toggleInline(5672,24560,0); javascript:amaf_insertHTML('');amaf_toggleInline(5673,24560,0);

Sir,
seriously you did not witness any cracking on any of our homes,
simply because there is a "Bond Break" between the skin and the stucco, we use "real" 7/8" thick troweled on stucco not the "faux" spray stucco that you use
I truly speak from experience with all types of SIPs including MGO

we build homes that look like homes, not just simple boxes

You can build any kind of House or Specialty building with MGO SIP. What is your point? javascript:amaf_insertHTML('');amaf_toggleInline(5681,24560,0); javascript:amaf_insertHTML('');amaf_toggleInline(5682,24560,0);

Look at your second picture of the unpainted stucco. That is called crazing and spider cracks. If you talk to any stucco expert or building scientist, you will find that 7/8" Stucco finishes went out over 20 years ago. Stucco failures and water intrusion is the cause of most construction related lawsuits and very rarely is stucco specified in today's construction world over 5/8" thickness.All building move and as you know metal panels are subjected to thermal expansion and move more than most common building materials. Thick stucco finishes cannot tolerate this movement and have a tendency to crack, allowing salt air and moisture into the structure. For this reason you are seeing elastomeric and synthetic stucco finishes replacing traditional stucco finishes. It is a better product and can handle the movement that occurs with all types of building structures. There are many whitepapers available on the internet about this very subject.

Hey Einstein! That's called cultured stone, directly applied to the metal skin with 3m adhesive

Listen my friend, this is a forum about MGO SIP panels and its purpose is to provide useful information to interested parties about the benefits of using this product. It is not a metal SIP forum. You seem to have some other disparaging agenda? If you wish to discuss metal panel SIPs, please setup your own forum about metal panels and take your comments there, maybe then someone will find some interest in what you have to say!

Sir, I never brought the subject up , you did !

Sir, this is a forum about MGO SIP panels. You clearly made disparaging comments about the type of homes you perceived that we manufacturer and posted pictures of yours to blow your own horn in our forum. Please, I have no interest in debating metal panel SIPs with you. I installed metal SIPs at the Fort Lauderdale airport in 1985 when only two companies in the USA could manufacture them, EG Smith and HH Robertson. Those patents expired in 1987 and the technology became available to companies like yours, so I assure you I'm well versed with your product and subsequent limitations. I think your comments would be more useful to consumers and less confrontational to others if you started your own forum about metal panels and posted your information there for the consummers that are actually interested in your product. This forum is for those interested in learning more about MGO SIP panels.

I must agree with Innova, I own a metal SIPS residential home that is stucco and the crack or crazing whatever you want to call it are all over the home. My metal SIP home is constantly "popping" do your MGO SIP panels do this? I regrettably used metal SIPS for my construction project, wish I would have done more research. Anyone considering SIPS construction should research and talk to SIP homeowners.
