| SongMao EPS ICF Block (Base) | Residential apartments, light commercial buildings | R-4.5 thermal resistance (ASTM C578) ▲ Interlocking design (reduces gaps by 40%) Lightweight (2.5 lbs/ft³) | Cost-effective insulation for moderate climates Easy installation (no mortar) | Lower R-value vs advanced tiers Limited fire resistance (Class B only) |
| SongMao EPS ICF Block (Advanced) | High-energy buildings, cold climates | R-5.0 thermal resistance (ASTM C578) ▲▲ Fire-resistant (Class A, ASTM E84) Moisture barrier (0.1% water absorption) | Superior thermal performance Meets strict fire codes Longer lifespan in humid areas | Higher upfront cost vs base tier |
| XPS (Extruded Polystyrene) | Commercial roofs, foundation insulation | R-5.0 thermal resistance (ASTM C578) Water-resistant (0.3% absorption) High compressive strength (40 psi) | Excellent moisture resistance Stable R-value over time | Expensive material Rigid panels require cutting tools |
| Polyurethane Foam Panels | Industrial warehouses, soundproofing | R-6.5 thermal resistance (ASTM C578) ▲▲▲ Acoustic dampening (43 dBA reduction) UV-resistant coating | Best thermal performance Reduces noise and vibration | Custom installation required Vulnerable to physical damage |
| Concrete Forms with Insulation | High-rise construction, seismic zones | Reinforced concrete core (2,500 psi compressive strength) Integrated EPS insulation (R-4.0) Fire-resistant (ASTM E119) | Structural integrity for heavy loads Combines formwork and insulation | Bulky to transport Higher labor costs |
| Aerated Autoclaved Concrete (AAC) | Low-rise buildings, acoustic barriers | Lightweight (35 lbs/ft³) Thermal resistance R-2.5 (ASTM C578) Acoustic insulation (STC 45) | Low carbon footprint Easy to cut on-site | Lower R-value vs foam alternatives Requires protective coatings outdoors |
