Buy Good Quality Silica Aerogel at Low Price at Wedge India. Looking for high-performance insulation with unmatched thermal resistance? Wedge India brings you premium-quality Silica Aerogel insulation products at competitive prices, suitable for a wide range of industrial and commercial applications. Known as the world’s lightest solid, silica aerogel delivers exceptional thermal insulation, low density, and superior fire resistance — making it ideal for use in oil & gas, refineries, LNG pipelines, building envelopes, and cryogenic systems.
What is Silica Aerogel?
Silica Aerogel is the most common and widely used type of aerogel, known for its exceptional insulation properties, ultra-low density, and translucent appearance. Made primarily from silicon dioxide (the same compound found in glass), it is often referred to as “frozen smoke” or “blue smoke” due to its ghostly appearance and light scattering.
Key Properties of Silica Aerogel:
Extremely Low Thermal Conductivity: As low as 0.013 W/m·K, making it one of the best thermal insulators available.
Lightweight: Up to 99.8% air by volume, making it lighter than foam or fiberglass.
High Surface Area: Can reach up to 800–1000 m²/g, useful in chemical and catalytic applications.
Temperature Resistance: Can withstand temperatures from -200°C to +850°C.
Non-combustible and Fire-Resistant: Ideal for passive fire protection applications.
Applications of Silica Aerogel:
Thermal Insulation for:
LNG pipelines
Oil & gas plants
Building façades and walls
Aerospace and defense
Cold chain & cryogenic containers
Acoustic Insulation: Blocks sound while maintaining a thin profile.
Daylighting Panels: Its translucency allows light diffusion without heat transfer.
Protective Clothing & Equipment: Used in gloves, jackets, and fire suits.
Why Choose Silica Aerogel?
Achieve maximum insulation in minimum thickness
Ideal for space-constrained or high-temp applications
Long-lasting and maintenance-free
Fireproof and waterproof, ideal for critical infrastructure
