Lightweight MgO Board (EPS Filled Fireproof Panel)

A1 Fire Rated · Ultra Light Weight · Thermal Insulation · Soundproof · Eco Friendly Building Material

Product Overview

Lightweight MgO Board is an upgraded magnesium oxide board enhanced with EPS (Expandable Polystyrene) particles inside the core structure. Compared with standard MgO boards (1000–1100 kg/m³), this lightweight version reduces density to 750–850 kg/m³, achieving around 30% weight reduction while maintaining A1 fire resistance and excellent structural performance.

This innovation makes installation easier, reduces transportation cost, and improves thermal insulation performance, making it ideal for modern energy-efficient building systems.
