  • Structurally Insulated Panels (SIPs)

Which MAXTERRA MgO Board Do I Use?

Our 12mm (1/2 inch) boards are used as exterior sheathing and interior walls. Our 18mm (3/4 inch) board is used as flooring underlayment.

Is MAXTERRA MgO Board considered a Green Building Material?

Yes, it is. NEXGEN MgO Board is a mineral product, completely free of toxins such as asbestos, formaldehyde or silica, is manufactured completely at ambient temperature, and is considered a green product. During the curing process, MgO absorbs carbon, making it carbon negative.

Is MAXTERRA MgO Board Carbon Neutral?

Yes. NEXGEN MgO Board is CO2 negative meaning the product and / or its process absorbs CO2 and turns it into magnesium carbonate and that remains in the board until the board is retired from service, in which case, the magnesium carbonate can be recycled to make MgO and ultimately recycled into more MgO Board.

Has MAXTERRA MgO Board been tested?

Yes indeed. Our MgO Board has been subjected to some of the toughest testing being conducted on building materials today including the freeze / thaw and 2,000-hour weathering test, which simulates 20 years of wear and tear in all climatic conditions, including high heat and snow. Our MgO Board far exceeded the ASTM requirements. For our sanded back product line, we have completed all testing in accordance with AC386 published by the ICC-ES, using specified ASTM test methods for all products marketed. Our 12mm and thicker standard density sanded back products are Underwriters Laboratory (UL) approved.

Is MAXTERRA MgO Board dimensionally stable?

Yes, it is. Unlike Portland type materials the coefficient of expansion for MgO Board is extremely low; therefore, when selecting and installing products such as our exterior lap siding, there is no need to leave gaps between butt joints to accommodate for such expansion and contraction. This provides a much more aesthetically pleasing finish for many years to come. Refer to our test summary for actual test results.

What finishes can you use with MAXTERRA MgO Board?

Excellent, allowing you to finish NEXGEN MgO Board with any product you desire such as paint, Portland type stucco, synthetic stucco, wallpaper, stone, tile, brick and much more. The excellent adhesion properties of MgO Board also make it a perfect product for Structural Insulated Panels (SIPS), Exterior Insulated Finish Systems (EIFS) and interior wall systems using fabrics.
