high density extruded board xps 50mm 1800mm × 600mm building insulation roof insulation fire prevention

Extruded Polystyrene Board (XPS Board) is a common building insulation material with the following characteristics:

1. **Excellent Insulation Performance**: Low thermal conductivity with significant insulation effect, suitable for insulation of walls, roofs, and floors.
2. **High Compressive Strength**: The structure is tight, with high compressive strength, suitable for ground insulation to bear larger loads.
3. **Moisture-proof and Water-resistant**: The closed-pore structure prevents water absorption, offering superior moisture-proof performance, making it suitable for humid environments.
