InMag wall sheathing panels are fire-resistant, high-density, structural magnesium oxide cement panels. When used as an exterior wall sheathing, InMag panels can replace other sheathing materials in certain assemblies, potentially reducing the number of layers required.
In common with all InMagboard products, InMagboard Sheathing is non-combustible for up to 2-hour fire rating, and has exceptional load-bearing strength.
Uniquely, these exceptional composite characteristics come from a single integral panel – a lightweight solution which cannot delaminate and is resistant to water, mold and insect damage.
Non-combustible as per ASTM E136 and IBC & IRC approved for up to 2-hour fire ratings. An excellent alternative for both wood and steel framing.
Reinforced glass fibre internal structure of the boards makes them highly durable and resistant to impact against seismic and lateral wind.
Lightweight and easy to install – perfect for easy handling and quick installation. Single trade fitted for on-site efficiency and reduced build times.
Inorganic cementitious materials do not grow mold (per ASTM G 21 0/0), and ensure zero nutritional value for complete resistance to termites and all wood-boring insects.
A unique formulation which can help building designers and contractors achieve critical sound ratings, with the ability to reach 55+ STC/IIC ratings.
Manufactured to industry-leading tolerances for on- and off-site precision. Resistance to water means panels remains structural while wet, and will not delaminate, warp, expand or bow in high-moisture, high-humidity environments.
InMagboard’s unique formulation features high-quality cementitious material reinforced with reinforced fiberglass mesh. Developed over more than two decades and rigorously tested in different labs across US and Canada. InMagboard panels deliver industry-leading testing results from fire resistance and sound insulation to shear, deflection, and shear diaphragm strength.
