Ceramic Wool Insulation | High-temperature industrial equipment, steam pipes | Thermal Conductivity: 0.045 W/m·K (Base) ▲0.035 W/m·K (Advanced) Temperature Resistance: Up to 1260°C (ASTM C611) | High thermal stability, lightweight, chemical inertness (ASTM D543) Fire-resistant (ASTM E84) | Higher cost, requires protective handling, lower R-value per inch than aerogel |
Fiberglass Insulation | Residential/commercial buildings, HVAC systems | Thermal Conductivity: 0.040 W/m·K (Industry) ▲0.038 W/m·K (Advanced) Resistance up to 480°C (ASTM C611) | Cost-effective, easy installation, fire-resistant (ASTM E84) Moisture-resistant (ASTM C1174) | Skin irritation risk, lower temp resistance than ceramic wool, less durable in extreme heat |
Polyurethane Foam | Refrigeration units, cold storage, building insulation | Thermal Conductivity: 0.025 W/m·K (Industry) ▲0.020 W/m·K (Advanced) Closed-cell structure (ASTM C1174) | High R-value, moisture-resistant, lightweight (ASTM D792) Flexible installation | Flammable unless treated (ASTM E84), environmental concerns (CFC-free versions available) |
Mineral Wool Insulation | Building walls/ceilings, acoustic insulation | Thermal Conductivity: 0.043 W/m·K (Industry) ▲0.039 W/m·K (Advanced) Fire resistance up to 750°C (ASTM E119) | Good acoustic insulation (ASTM E90), eco-friendly (recyclable), fire-resistant | Heavier than ceramic wool, limited to lower-temperature applications (max 750°C) |
Aerogel Insulation | Cryogenic equipment, high-end buildings | Thermal Conductivity: 0.018 W/m·K (Industry) ▲0.015 W/m·K (Advanced) Ultra-lightweight (ASTM D792) | Best thermal performance, thin profile, durable (ASTM D543) | Very expensive, brittle, requires careful handling, niche applications |
Cellular Glass Insulation | Below-grade insulation, chemical-resistant areas | Thermal Conductivity: 0.048 W/m·K (Industry) ▲0.045 W/m·K (Advanced) Chemical resistance (ASTM D543) | Waterproof, chemical-resistant (ASTM D543), long lifespan (ASTM C1106) | Heavy, higher cost than fiberglass, limited temp range (up to 120°C) |
