What is Aerogel Insulation?

Aerogel is a granular grade insulation materials produced by extracting the liquid component of a gel through supercritical drying. This allows the liquid to be slowly drawn off without causing the solid matrix in the gel to collapse from capillary action, as would happen with conventional evaporation. ASTM C168 defines an Aerogel as – “A homogenous, low density solid phase material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The resulting material has a porous structure with an average pore size below the mean free path of air molecules at standard atmospheric pressure and temperature”.

Key Properties of Silica Aerogel

Discover premium aerogel insulation and silica aerogel blankets in India with Wedge India. Explore high-performance aerogel properties and versatile applications—from industrial pipelines to EV battery thermal management. Get customized solutions and fast delivery for superior thermal protection. Silica aerogel is widely recognized as the lightest solid material and one of the best thermal insulators in the world. At Wedge India, our high-performance aerogel insulation products are engineered to deliver the following key properties:

Ultra-Low Thermal Conductivity: As low as 0.014 W/m·K, significantly lower than traditional materials like mineral wool, fiberglass, or PU foam. Reduces heat loss even in extreme temperatures (–200°C to +650°C).

High Surface Area: Over 600–800 m²/g internal surface area due to nanoporous structure. Offers exceptional thermal blocking while remaining breathable.

Hydrophobic & Moisture-Resistant: Naturally repels water while allowing vapor diffusion. Prevents mold growth and maintains insulation performance in humid or wet environments.

Non-Combustible & Fire-Resistant: Rated Class A (EN 13501-1) or ASTM E84 Class 0. Does not burn, melt, or release toxic fumes—ideal for fire-prone zones.

Flexible Yet Durable: Available in blanket, panel, and sheet form with aluminum or PET backing. Can withstand vibrations, mechanical shocks, and compression without degradation.

Lightweight & Space-Saving: Over 90% air by volume, yet incredibly strong. Ideal for applications where weight and thickness are critical—like EV batteries, aerospace, and retrofits.

Acoustic Damping: Reduces sound transmission—useful in buildings, automobiles, and appliances for thermal + sound insulation.

FAQs – Aerogel Blanket India

1. What is an aerogel blanket?

An aerogel blanket is a flexible insulation material made by embedding silica aerogel into a fiber matrix. It offers ultra-low thermal conductivity, fire resistance, and is extremely lightweight—making it ideal for space-saving insulation. An aerogel blanket is a flexible, high-performance insulation material made by integrating silica aerogel into a fiber matrix. It provides ultra-low thermal conductivity, excellent fire resistance, and is one of the lightest solid materials—making it ideal for space-constrained, high-efficiency applications in pipelines, buildings, and electronics.

2. Where can aerogel blankets be used in India?

Aerogel blankets are used across multiple industries in India including:

Building insulation (walls, roofs, facades)
Oil & gas pipelines
HVAC ducting
Cold chain systems
EV battery thermal management
Aerospace and defense

3. How does aerogel compare to other insulation materials?

Silica aerogel has the lowest thermal conductivity among commercial insulators—better than glass wool, rockwool, or polyurethane foam. It performs efficiently in extreme temperatures and requires significantly thinner profiles for the same R-value. Silica aerogel has the lowest thermal conductivity (~0.013–0.020 W/m·K) among commercially available insulations.

Less thickness is needed to achieve the same R-value
It performs in a wide temperature range: –200°C to +650°C
Offers Class A fire safety and space-saving design

4. Is aerogel blanket fire-resistant and waterproof?

Yes. Wedge India’s aerogel blankets are:

Fire-rated (Class A / Class 0)
Hydrophobic: repels water while allowing vapor diffusion

This makes them suitable for high-humidity and fire-sensitive environments.
