Simplifying Construction Nationwide.
Wherever your project is, Oaksource ICC certified MgO panels are ready to deliver smoother installs and superior performance. We ship our ICC certified wall, floor, and SIP panels across the United States — yes, coast to coast.
Environmentally Friendly
Crafted from natural magnesium sulfate, our panels are manufactured using a low-energy process, making them an eco-conscious and sustainable building solution.
Built for Builders
Lightweight yet incredibly strong and durable, our panels offer smooth finishes, exceptional screw and nail holding strength, and can be easily scored and cut on-site.
Insect-Resistant
100% inorganic and free from any organic content, our panels do not attract termites, carpenter ants, or other wood-damaging insects.
Weather-Ready
Fire-Resistant
ASTM-tested and A1 fire-rated, our panels provide a reliable fire-resistant option for both residential and commercial construction projects.
Moisture-Resistant
Engineered to hold its shape, our product resists warping, swelling, and delamination when exposed to short-term moisture. (Note: extended exposure is not recommended.)
Safe for Indoor Air Quality
Free from formaldehyde, fly ash, crystalline silica, and toxic chemicals, our panels are ideal for individuals with asthma, allergies, or chemical sensitivities.
Mold & Mildew Resistant
Thanks to its moisture resistance and antimicrobial properties, our panels naturally resist mold, mildew, rot, and fungal growth.
