When it comes to thermal insulation, few materials match the performance of Aerogel. Known as “frozen smoke” or “solid air,” Aerogel is an ultra-lightweight, highly porous material with the lowest thermal conductivity of any solid. At Wedge India, our WedGel® Aerogel Insulation products are engineered to deliver maximum heat resistance, energy efficiency, and safety — across industries from construction to aerospace, cryogenics, and electric vehicle batteries.
1. Exceptional Thermal Performance
With thermal conductivity as low as 0.015 W/m·K, WedGel Aerogel outperforms traditional insulation materials like fiberglass, mineral wool, and foam. This means:
Up to 2–4× better insulation at the same thickness
Lower heat transfer in high-temperature and cryogenic conditions
Significant energy savings in heating and cooling applications
2. Space-Saving Thin Profiles
Aerogel’s high R-value per inch (R-10 to R-30) allows for thinner insulation layers without sacrificing performance. This is ideal for:
Retrofitting buildings where space is limited
Industrial equipment with tight clearances
Lightweight design requirements in transport, marine, and aerospace sectors
3. Lightweight but Strong
WedGel Aerogel is one of the lightest solid materials on Earth, yet it is mechanically robust. This combination reduces structural load, simplifies installation, and maintains durability in demanding environments.
4. Hydrophobic & Moisture Resistant
Our Aerogel products are up to 99% hydrophobic, repelling water while allowing vapour diffusion. This prevents:
Moisture absorption and performance degradation
Mold, mildew, and corrosion issues
Insulation failures in humid or wet environments
5. Superior Fire Resistance
Benefits of Aerogel Insulation - WedGel Aerogel is non-combustible with Class A fireproof ratings, offering:
Flame spread index ≤ 25
Smoke developed index ≤ 50
Additional safety in building, industrial, and EV battery applications
6. Versatile Application Range
We offer Aerogel in multiple forms — blankets, panels, powders, coatings, and pads — making it suitable for:
Building walls, roofs, and façades
Cryogenic pipelines and storage tanks
EV battery thermal barriers
High-temperature process equipment
Aerospace and defense insulation systems
7. Energy-Efficient Insulation
Benefits of Aerogel Insulation - By minimizing heat loss and gain over decades, Aerogel insulation reduces utility costs, carbon emissions, and maintenance expenses, contributing to greener, more sustainable operations.
Benefits of Aerogel Thermal Insulation Material
Aerogel insulation is revolutionizing the thermal insulation industry. Often called “frozen smoke” or “solid air”, this high-performance thermal insulation material delivers exceptional energy savings, durability, and safety. Benefits of Aerogel Insulation - At Wedge India, our WedGel® Aerogel Insulation offers one of the lowest thermal conductivities in the world (0.015 W/m·K), making it an ideal choice for construction, industrial applications, and EV battery insulation.
High R-value Insulation
With R-values of R-10 to R-30 per inch, WedGel® Aerogel provides up to 4× better performance than traditional materials like fiberglass, mineral wool, or foam boards. This results in:
Minimal heat loss and gain
Significant reduction in energy costs
Consistent performance in extreme temperatures from -200°C to +1400°C
Fire-Resistant for Enhanced Safety
Our fire-rated aerogel insulation is non-combustible with:
Flame Spread Index ≤ 25
Smoke Developed Index ≤ 50
Compliance with Class A fireproof ratings
Perfect for building insulation, fire barriers, and battery safety layers in EV applications.
EV Battery Thermal Barrier
Thermal management in electric vehicle (EV) batteries is critical. WedGel Aerogel pads and wraps:
Reduce risk of thermal runaway
Maintain stable cell temperatures
Optimize battery performance and extend life
This makes Aerogel the preferred EV battery thermal barrier material.
Long-Term Energy & Cost Savings
By drastically reducing heat transfer, aerogel insulation lowers heating and cooling needs. This results in:
Lower utility bills
Reduced carbon footprint
Minimal maintenance over decades
