MgO Boards Fireproof Ductworks Applications

MgO (Magnesium Oxide) boards are high-performance, non-combustible materials widely used in HVAC and smoke exhaust systems. Because of their Class A fire rating, resistance to moisture, and lightweight nature, they are ideal for preventing the spread of fire, smoke, and toxic gases in commercial and residential buildings.

MgO Fireproof Ductworks

MgO Boards for Ductworks Benefits

A1 non-combustible with zero toxic smoke under fire, fully water and mold resistant compared to gypsum, and feature natural sound absorption to lower noise transfer in ventilation systems.

fire safety

Fire Safty

MgO boards are fully non-combustible with A1 fire ratings per EN 13501-1 & ASTM E136, retaining structural stability during prolonged fire exposure with no toxic fumes released.

moisture proof

MOISTURE AND MOLD PREVENTION

Different from regular gypsum boards, MgO panels repel water absorption, offering strong resistance against dampness, mold and bacteria inside ventilation ducts.

Sound Dampening

SOUND DAMPENING

This material features natural sound absorption performance, efficiently cutting noise transfer across HVAC and exhaust pipeline systems.
