Specifications:


MgO boards are sustainable non-flammable panels for commercial and residential builds. They offer 2–3 hours dependable fire protection, stay intact at 800°C and only ignite above 1200°C.

MgO boards hold steady under dampness and bending loads. They stop warping, swelling and delamination to sustain reliable long-term structural performance.

This panel contains zero fly ash, formaldehyde, silica or toxic substances. Its pure raw material blend delivers safe installation for all indoor and outdoor construction projects.


The board naturally repels moisture, mold and pest infestation. It blocks termite harm and structural decay to greatly prolong the service lifespan of buildings.

Crafted from natural mineral blends, MgO panels are fully recyclable with low environmental footprint. They pass 36-month freeze-thaw tests for all-season exterior usage.

Boards carry strong antimicrobial properties to fend off mold, mildew and rot. Chloride-free composition removes micro-corrosion and swelling risks entirely.
Subflooring & Underlayment: Used in modular building systems. The sanded profile ensures an even base that prevents uneven ridges under sensitive finished floors like vinyl or laminate
