US MgO Company is proud to announce the launch of the Innovation MgO series of cement sheathing panels available for commercial and multifamily buildings nationwide. Based on a proprietary formula of the highest-performing magnesium oxide (MgO) cement in the market, Innovation MgO sheathing panels boast industry-leading structural strength, durability, fire resistance, and ease of installation.


Innovation MgO Sheathing Panels

Innovation MgO panels outperform wood-based, gypsum-based, and Portland cement-based panels in many technical categories. Panels are naturally fire-resistive, provide industry-leading flexural strength and dimensional stability, and provide high durability as they withstand weather conditions better than alternatives.

1/4” Flex Panels are ideal for the interior wall portion of SIP and SIS products. They may also be used for interior gypsum replacement in high traffic areas.

1/2” Wall Panels replace wood and gypsum-based panels in exterior load bearing fire-rated walls with additional use in interior fire-rated walls.

1/2” and 3/4” Subfloor Panels save time and labor by serving as structural fire-resistant subfloors and flooring underlayment.


Featured: Innovation MgO 1/2” Wall Panels

Innovation MgO 1/2” Wall Panels are our flagship high-density product developed to replace fire-rated wood and gypsum-based exterior wall panels in Type I, II, and III commercial and multifamily buildings.

Innovation MgO 1/2” Wall Panels are pending final approval for use in all building types I, II, III, IV, and V per ASTM E136 / IBC 2021.  Panels are classified as noncombustible Class A1 fire-resistant with independent 1 and 2-hour fire ratings as tested to ASTM E119. Consult published Innovation MgO assembly requirements and local building codes for fire-rated design requirements.

Innovation MgO 1/2” Wall Panels are easily installed using traditional tools and methods. One panel can be used in a multitude of applications and attaches easily to both metal and wood studs, reducing hassle, and saving both time and money.
