Study Notes
Expanded Polystyrene (EPS)
- Made from expanded polystyrene beads fused together.
- Thermal Conductivity: 0.032 - 0.038 W/m·K.
- Density: 15-25 kg/m³.
- Water Resistance: Less resistant to water absorption than XPS.
- Applications: Residential and commercial buildings for wall and roof insulation, in panels, blocks, and loose-fill applications.
- Advantages: Cost-effective, lightweight, easy to handle, good thermal performance.
- Disadvantages: Lower moisture resistance, less durable under high compressive loads.
Extruded Polystyrene (XPS)
- Made by extruding polystyrene foam, which forms a closed-cell structure.
- Thermal Conductivity: 0.029 - 0.035 W/m·K.
- Density: 30-50 kg/m³.
- Water Resistance: Very low water absorption due to its closed-cell structure.
- Applications: Below-grade insulation (foundations, basement walls), in areas exposed to moisture, insulation for roofs, walls, and under concrete slabs.
- Advantages: Excellent moisture resistance, higher compressive strength than EPS, good thermal performance.
- Disadvantages: More expensive than EPS, less environmentally friendly.
Graphite Polystyrene (GPS)
- Similar to EPS but with graphite added to improve thermal insulation properties.
- Thermal Conductivity: 0.031 - 0.033 W/m·K, lower than EPS due to the presence of graphite.
- Density: 20-30 kg/m³.
- Water Resistance: Comparable to EPS, not as resistant as XPS.
- Applications: Similar applications as EPS, including residential and commercial buildings.
