Why engineers specify aerogel insulation
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: 0.018 W/m·K at 25 °C for WedGel blankets. 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ASTM C168 defines an aerogel as a low-density solid made from a gel in which the liquid has been replaced by gas, leaving pores smaller than the mean free path of air. Silica aerogel has a surface area of 600–800 m²/g and is more than 90% air by volume. WedGel blankets are tested to ASTM C1728 (flexible aerogel blanket) and ASTM C177 (thermal conductivity).

Aerogel insulation FAQs
What is an aerogel blanket?
An aerogel blanket is a flexible roll of silica aerogel bonded into a glass-fibre, ceramic-fibre or PET carrier. It keeps aerogel’s 0.018 W/m·K conductivity in a form that can be cut with a knife and wrapped around pipes, tanks and equipment. WedGel blankets come in 3–20 mm standard thicknesses, plain or laminated.
What is the price of aerogel insulation in India?
Aerogel blanket costs ₹1,350–₹4,500 per m² ($14–$47) 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; thicker and speciality grades go up to ₹4,500/m². Samples under 20 m² cost 20–30% more.
What is the thermal conductivity of aerogel insulation?
WedGel aerogel blankets measure 0.018 W/m·K at 25 °C (ASTM C177), with grades ranging from 0.017 to 0.023 W/m·K. 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.
Which aerogel thickness should I choose?
As a rule of thumb for hot pipes: 5–6 mm for up to 150 °C personnel protection, 10 mm for 200–400 °C process lines, 15–20 mm (or two layers) for 400–650 °C steam and furnace surfaces. For cryogenic lines, 10–20 mm of 200 or 200HP grade. The exact figure depends on pipe size and the surface temperature or heat loss you need; use the insulation thickness calculator or send us your line list for a free sizing.
Do you supply custom sizes and laminated aerogel?
Yes. Blankets are slit to custom widths and die-cut to drawings, and are available plain, aluminium-foil-laminated (150AL), PET-backed, silica-cloth-faced (125A, 650HP) or adhesive-backed (CAC350). Pads for EV packs, refrigerators and tanks are made to your dimensions.
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.
Is aerogel insulation fireproof and waterproof?
Silica aerogel is inorganic and non-combustible: WedGel blankets are Class A to ASTM E84 and EN 13501-1 and tested to ISO 1182, pastes and coatings carry a Class A rating, WJ120 paint is Class A2, and EV grades meet UL94 V0. All blankets are hydrophobic with over 99% water repellency (GB/T 10299) while remaining vapour-permeable. Check the TDS for the grade you specify.
