What are the major difference between MGO and OSB SIP panel products?

There are two important differences between MGO panels and OSB SIP panels.

I. R-Value Both the MGO skin and EPS foam core have very high thermal insulating values. In other words, the MGO panel skin is a very effective and fire resistant insulating material on its own, and paired with EPS foam makes a very versatile and high R-Value insulated building panel product. If you relate this test information to that of a cold winter day, the cold temperature needs to penetrate the MGO skin prior to passing through the EPS foam core.

II. Fire resistance MGO panel skin when applied directly with a 1100C torch flame for 45 minutes will not burn, while limiting the heat transferred. One side of the panel will be 1100C while the opposite side will only reach a max of 134C over 45 minutes. We would not recommend a similar torch flame test with OSB for obvious reasons.

How are panels connected and joined during construction?

There are several joint options for connecting panels. In most cases a wooden spline is the preferred method for joining panels. The type, size and frequency of splines is an engineering design consideration and can be customized for particular applications, environments, and load bearing requirements. The most common spline configurations are 2" x 6" on 24" centers. Double splines 2x (2" x 6") enable equivalent load capacity to that of single splices on 48" centers. Generally, toe-nailing fastening (fasteners installed at angles) is not a preferred method of joining panels. Engineers prefer a more controlled and consistent method of panel installation, as well as a method that can be confirmed and inspected on site.

Are alternatives to wooden splines available?

Yes. In some cases the wooden splines are replaced with EPS splines. However, this reduces the load capacity of the wall, and may require structural elements to be engineered into the design. It is best to discuss with engineer for suitable alternatives.

Are blower test results available for a MGO panel based building?

Yes, detailed blower tests results are available upon requests. In general SIP buildings are designed to be very air-tight and the MGO panels help maintain a building's air-tight envelope. Test results are more of a reflection of the overall buildings air-seal. By themselves MGO panels are airtight.

How can water saturation effect MGO panels?

When building with MGO panels it is recommended to use coated fasteners on specific increments, as well as using protective measures to eliminate water penetration. In Asia MGO products are a very popular building material but are renowned for the corrosive effects caused by the MgCl2 that may leech out over time due to moisture. The exposure to resulting MgCL2 may corrode any untreated metal fasteners. There is also evidence to support corrosive effects when moisture is present creating a "saturated effect" and there can be issues if non-coated fasteners are used.

Can MGO panels be used as part of a flooring system?

Yes, MGO panels can be used as part of a flooring system. MGO panels are typically used for lowest floor in a building project. Typically, TJI floor systems are used for the internal floor systems, and MGO panels for the basement, or ground floor.

Additional information can be reviewed on our online site: www.mgosip.com

Anchoring a garage slab to a MGO frost-wall.

Designing a garage with MGO panel frost walls and a concrete slab floor is no different than if the walls were concrete frost walls. The slab gets poured inside the walls and becomes a floating slab. Some soil conditions may require Piles Overall, MGO panels can speed up construction when used as a frost-wall because they can be back-filled immediately with no need to wait for concrete to cure and curbing to be removed.

How are exteriors like Parging and Hardie plank installed on MGO panel walls?

Parging like exterior finishes can be installed on a MGO panel in a similar manner as installing parging on a concrete wall. Hardie plank can be installed on MGO panel walls in a similar manner as installing against a standard OSB or plywood wall. The major difference between installing Hardie plank on MGO vs. OSB is that the fastener used will have extra holding capacity with the MGO panel, and that treated fasteners need to be used.

Can MGO panels be finished with Miracote?

Yes, Miracote would be a very effective finishing material.

What is the maximum length of panel that can be fabricated and safely handled?

MGO Panels can be created and cut out in a variety of sizes and specs. The standard sizes have a maximum length of 12ft and custom sizes can be upto 28ft long.

What is the resistance to impact for an industrial application?

MGO is designed to be impact resistant. The panel is constructed of two layers of fiber mesh that sandwich the MGO core giving it a impact resistant characteristic. MGO panels have similar impact resistance to that of Concrete Board. Please view this video for impact resistance demonstrations. (VIDEO)

Is there any risk of washing MGO panels with a high-pressure washer?

MGO panels are very durable and water resistant; they are easily and safely cleaned off with high-pressure washing equipment. Commercial car washes are one of the many uses for MGO panels because of their insulating properties and natural resistance to mold, water and impacts.

If MGO panels do get damaged, how can they be repaired?

If an MGO panel does get damaged the best practice for repair is to use a fiberglass Reinforced Automotive Body-fill product or a contentious Filling Compound.

Provide details of the surface profile on interior and exterior.

MGO panels are finished with a paint grade smooth finish on both sides. Panels will require a high grade of primer or paint to coat the sheet. Lower paint grades will not provide a complete cover and small pin size holes will appear after a single coat of paint. Skim fillers or additional coatings of paint will cover any pin holes. For more information on coating applications please view this video for a coating demonstration. (VIDEO)

Do you have a sound absorption coating or covering we could consider for some of the interior side surfaces?

Yes, higher the normal STC ratings can be achieved with coatings. For more information and options please contact one of our sales technicians.

The #1 asked Question. "If this product is so great, why have I not heard of it before?"

Good question. Although MGO products are available around the world, SIP building technology is just coming into it's commercial maturity in North America, as consumers become more aware of the many advantages of SIP over traditional stick frame building technology. MGO technology is also relatively new for North America, but a familiar "go-to" solution in the rest of the world. As prices for traditional North American building materials level-off with materials from the rest of the world, and consumers here become more aware of better options, we will be seeing more MGO SIP technology being applied here.

What is the Definition of R-Value?

R-value is the measure of how resistant a material is to heat flow. If heat flows quickly through a material it has a very low resistance, and therefore a low R-Value; material that resists heat flow has a very high R-value.

Real MGO Example: An MGO panel when directly applied with a 1100C torch flame for 45 minutes will not burn, while limiting the heat transferred. One side of the panel will be 1100C while the opposite side will only reach a max of 134C over 45 minutes.

Eg. The heat resistance to heat flow through the MGO is very high, and therefore has a high R-Value rating.
