Aerogel is the world’s lightest solid: up to 99.8% air, held in a labyrinth of microscopic pores that throttles heat flow. Peer-reviewed research describes aerogels as nanoporous materials with ultra-low thermal conductivity that are drawing growing attention for aerospace vehicle insulation. The same literature is candid that mechanical fragility has held back adoption.

DashamLabs addresses that directly. Silica aerogel is integrated into a fibrous matrix with reinforcing layers, so the finished blanket is flexible, safe to handle and tough enough for real installation. The payoff for a designer is simple: reach your thermal target with 70% lower thickness, then spend the recovered clearance and mass on equipment, payload or margin.

Thickness options are 3 mm, 5 mm and 10 mm, so you can match the blanket to the space you actually have. Thicker is not always better; the right build-up depends on your temperature profile, surface and thermal target, and our team can help you work through it.

Two temperature figures appear on this page, and they describe different things.

• –50 °C to +650 °C is the continuous operating temperature. Use it for steady-state design.
• –200 °C to 1,000 °C is the temperature range the technology addresses, from cryogenic conditions to high-heat exposure. It is the wider envelope, not a continuous rating.

If your profile includes cryogenic service or short-duration high-heat exposure, request the TDS, which covers specifications, performance curves, safety data and installation guidelines, and talk to our team about your conditions. For the background, read aerogel performance at –50 °C vs 650 °C.

Fire performance. The blanket is fire-resistant and non-combustible. That is a material description, not a certification claim; if your programme specifies a flame, smoke or toxicity standard, test a sample against it. More in our post on fire resistance of silica aerogel blankets.

Moisture. A hydrophobic treatment keeps water out and mitigates corrosion under insulation, which matters for equipment that sees condensation, washdown or humid storage.

Handling. Lightweight, flexible and safe to handle, the blanket wraps irregular and curved surfaces and suits retrofit and confined spaces. Fewer awkward cuts and fittings mean less time on the installation floor. See mechanical strength and flexibility.

Why is aerogel insulation used in aerospace and defence? Aerogel is a nanoporous solid, up to 99.8% air, with very low thermal conductivity, so a thin, light layer can do the work of a much thicker conventional one. That matters wherever weight, volume and heat compete for the same space. DashamLabs’ silica aerogel insulation blanket offers λ ~ 0.016 W/m·K at room temperature in a flexible, fire-resistant, hydrophobic format.

How thin can aerogel insulation be? DashamLabs’ blanket is offered in 3 mm, 5 mm and 10 mm thicknesses. The published figure is 70% lower thickness than traditional insulation. The right thickness for your design depends on your temperature profile, surface and thermal target, so share those with our team, request the TDS and test a sample against your requirement.

What temperature range can the blanket handle? Continuous operation is –50 °C to +650 °C. The technology’s wider temperature range is –200 °C to 1,000 °C, from cryogenic conditions to high-heat exposure. Design steady-state conditions to the continuous range, and share any cryogenic or short-duration high-heat requirements with our team so they can be reviewed against the TDS.

Is aerogel insulation fireproof? DashamLabs’ aerogel blanket is fire-resistant and non-combustible. We use those terms rather than “fireproof”, and we do not publish a fire-classification rating. If your programme requires a specific flame, smoke or toxicity standard, request the TDS and MSDS and test a sample against that standard.

Is DashamLabs aerogel qualified for flight or defence use? Qualification is defined by your programme’s specification, not by a datasheet alone. DashamLabs has not published aerospace or defence qualification data. What we offer is a manufacturer’s TDS and MSDS on request, samples in 3, 5 and 10 mm for testing, and direct technical support to help you evaluate the blanket against your own requirements. 

Can I get samples and bulk rolls? Yes. Samples are 1 m² sheets (3 m × 330 mm) in 3, 5 and 10 mm, in limited quantities for qualified projects, for testing, prototyping and pilots. For volume production, bulk rolls are 20 m × 1.5 m (30 m² per roll) in 10, 5 and 3 mm. Use the sample request form and tell us about your application.

Who makes aerogel insulation in India? DashamLabs manufactures silica aerogel insulation blankets in India, at IMT Bawal in Rewari, Haryana, using its own patented technology. It is a manufacturer, not a trading company, backed by Speciale Invest, IIMA Ventures and Theia Ventures, with ARCI as technology partner. Supply is direct from the manufacturer, with technical documentation and installation guidance.
