What is aerogel insulation?
Aerogel insulation is a nanoporous silica material, reinforced with a glass-fibre, ceramic-fibre or PAN carrier, that has the lowest thermal conductivity of any commercial insulation: 0.017–0.023 W/m·K. Its pores are smaller than the path air molecules travel between collisions, which blocks conductive and convective heat transfer. For the same heat loss, it can be 2–3 times thinner than mineral wool.
ASTM C168 defines an aerogel as a low-density solid made from a gel in which the liquid has been replaced by gas, leaving pores smaller than the mean free path of air. WedGel blankets are tested to ASTM C1728 (flexible aerogel blanket) and ASTM C177 (thermal conductivity). Read the full explainer: what is aerogel insulation.

Aerogel vs mineral wool, PUF and calcium silicate
Aerogel costs more per m² than conventional insulation but needs far less thickness. That pays back where space, weight or corrosion under insulation matters.
| Property | WedGel aerogel blanket | Mineral / rock wool | PUF / PIR | Calcium silicate board |
|---|---|---|---|---|
| Thermal conductivity at 25 °C (W/m·K) | 0.017–0.023 | 0.033–0.040 (typical) | 0.022–0.028 (typical) | 0.050–0.060 (typical) |
| Maximum service temperature | 650 °C (1,000 °C rigid panel) | up to about 650–750 °C | about 110–130 °C | 650–1,000 °C |
| Cryogenic use | Yes, to −200 °C | Limited | Down to about −50 °C | No |
| Thickness for the same heat loss | 1× (reference) | about 2–2.5× | about 1.3–1.5× (low temperature only) | about 3× |
| Water uptake | Hydrophobic, 99% repellency | Absorbs water unless treated | Low | Absorbs water |
| Form | Flexible roll, cut on site | Slab, roll, pipe section | Sprayed or panel | Rigid board, pipe section |
Competing-material values are typical published ranges for comparison only; check the specific product’s data sheet. Wedge Industries Limited also supplies calcium silicate boards, spray foam insulation and microporous insulation where they suit the job better.

Aerogel insulation FAQs
What is the price of aerogel insulation in India?
Aerogel blanket costs about ₹1,350–₹3,850 per m² ($14–$40) for project orders of 100 m² and above, ex-works Faridabad, excluding 18% GST. A 5 mm ambient grade starts around ₹1,350/m²; a 10 mm 650 °C grade costs ₹2,950–₹3,850/m². Samples under 20 m² cost 20–30% more.
What is the thermal conductivity of aerogel insulation?
WedGel aerogel blankets measure 0.017–0.023 W/m·K at 25 °C (ASTM C177). The flagship WAG650 is 0.018 W/m·K at 25 °C and 0.068 W/m·K at 600 °C. The aerogel vacuum insulation panel reaches 0.005 W/m·K.
What temperature can aerogel insulation withstand?
Flexible WedGel blankets are rated from −200 °C (cryogenic grades) to +650 °C (WAG650, 650HP). The RP1000 rigid panel is rated up to 1,000 °C, and the WAG 650EV battery pad withstands 1,400 °C flame exposure.
Is aerogel better than mineral wool or rockwool?
For the same heat loss, aerogel is typically 2–2.5 times thinner than mineral wool, because its conductivity is about half. It is also hydrophobic, which reduces corrosion under insulation. Mineral wool is cheaper per m², so it suits jobs where space and moisture are not constraints.
What thickness of aerogel do I need?
It depends on operating temperature, pipe size and the surface temperature you need to reach. Use the insulation thickness calculator or send us your line list for a free sizing.
Is aerogel insulation fireproof?
Silica aerogel is inorganic and non-combustible. WedGel pastes and coatings carry a Class A fire rating, WJ120 paint is Class A2, and EV grades meet UL94 V0. The fire class depends on the grade and carrier, so check the TDS for the grade you specify.
Do you export aerogel insulation outside India?
Yes. Wedge Industries Limited exports to 45+ countries, including the UAE, Saudi Arabia, Qatar, Kuwait, the UK and the USA. We quote in USD for export orders.
