Choosing the Right Insulation Material: A Practical Guide
Selecting the right insulation material can be challenging, especially when balancing performance, safety, and cost. At Qian Dynar, we supply a wide range of insulation materials and chemicals, and we often guide clients on how to choose the most suitable option. Here are key factors to consider.
1. Application Environment
Cryogenic facilities, high-temperature plants, and HVAC systems each require different insulation properties. Different environments require different insulation strengths:
Aerogel blankets – Excellent in extreme hot or cryogenic conditions.
-
Polyurethane (PUR) & Polyisocyanurate (PIR) foams – Widely used for building envelopes, refrigeration, and pipelines.
-
Mineral wool – Reliable in high-temperature applications like oil & gas and power plants.
-
Cellular glass – Best for petrochemical environments and underground systems.
2. Moisture and Corrosion Resistance
Water ingress is one of the biggest threats to insulation performance. Materials with hydrophobic qualities, like aerogel, provide superior moisture resistance.
Aerogel – Naturally hydrophobic, resists water absorption.
-
Cellular glass – Impermeable to moisture and chemicals.
-
Jacketing with Polysurlyn moisture barriers – Prevents corrosion under insulation (CUI).
3. Fire Safety
For applications where fire resistance is critical, mineral wool and PIR foam are reliable choices. Mineral wool is non-combustible, while PIR offers fire-retardant properties, making them standard solutions in environments where safety is the top priority.
4. Cost and Long-Term Value
While PUR and PIR foams are highly cost-effective and easy to install, aerogel blankets, though higher in upfront cost, deliver unmatched performance and long-term savings through reduced heat loss and lower maintenance needs. Fiberglass insulation offers a balance of affordability and soundproofing, making it suitable for both industrial and building applications.
