MGO waterproof SIP panels are a lightweight, fireproof, waterproof building material composed of magnesium oxide boards with a core material like polystyrene foam or rock wool. The panels come in various sizes from 4-20cm thick and weigh 15-30kg/m2, making them lighter than other wall panels. They have a fireproof rating of Class A and can withstand soaking in water for days without losing integrity. MGO panels also provide soundproofing of up to 36dB and insulation. They are 100% environmentally friendly and easy to install through cutting, planning, drilling, and other common techniques.
