Aerogel cost per kg is one of the highest-intent searches in this industry, yet most published answers avoid giving numbers. This guide lays out indicative price ranges for the main product formats, explains why quotes from different suppliers can differ by a factor of three or more, and shows how to compare offers on a like-for-like basis. Ranges below reflect publicly quoted prices and trade disclosures across Chinese factories, European and North American brands, and research-grade suppliers; treat them as orientation, not as a live quote.
Aerogel cost per kg: indicative ranges by product format
Silica aerogel insulation is sold in several formats, and the per-kilogram price moves sharply between them. Granular material and standard-thickness blankets are the volume products; monolithic pieces and research powders sit at the expensive end.
| Product format | Typical use | Indicative price range (USD per kg) |
|---|---|---|
| Aerogel granules / particles | Cavity fill, daylighting panels, additives | 2–6 (bulk, factory China) |
| Aerogel blanket, 5–10 mm, standard density | Industrial and building insulation | 3–8 (bulk, factory China) |
| Aerogel blanket, small orders / cut pieces | Trials, maintenance, repairs | 8–15 (any origin) |
| Brand-name blanket (Western suppliers) | Project-specified, certified systems | 15–40+ |
| Aerogel panels / VIP composites | Space-constrained construction, appliances | 6–20 |
| Monolithic or research-grade aerogel | Laboratory, R&D, optics | 50–500+ |
Two structural reasons explain the spread. First, the silica precursor (water glass versus TEOS/TMOS routes) sets the cost floor: TEOS-based chemistry costs several times more per kilogram of finished product. Second, supercritical drying lines amortize capital across volume, so a factory running continuous lines quotes materially lower than pilot-scale producers. China now hosts the majority of global blanket capacity, which is why factory-direct China quotes anchor the low end of these ranges.
Aerogel blanket price: factory China versus brand channels
The query aerogel blanket price factory china deserves a direct answer, because the factory-to-brand spread is the single largest source of price confusion in this market.
Factory-direct from China
For container-load volumes of standard 5–10 mm hydrophobic silica aerogel blanket, Chinese producers commonly quote in the USD 3–8 per kg range, with per-square-meter equivalents of roughly 4–10 USD/m² depending on density and thickness. Quotes usually specify density (typically 180–220 kg/m³), thermal conductivity (0.018–0.022 W/m·K at mean temperature), and hydrophobicity (typically ≥ 98% water contact angle). Lead times run 2–6 weeks. Payment terms for first orders are commonly 30–50% deposit with balance against B/L copy; established relationships move toward net terms.
Western brands and distributors
Brand-name blanket systems from established Western suppliers typically land at USD 15–40 per kg or higher once distributor margins, certifications, project support, and liability coverage are included. The premium is not only margin: brand channels carry third-party fire certifications for specific assemblies, engineering support for specification compliance, and consistent lot traceability. For projects where a specification names a certified system, the premium buys spec compliance rather than raw material performance.
Where the value breaks
For commodity industrial insulation where the buyer controls the specification, factory-direct sourcing frequently delivers 40–70% material cost savings. Where a project is specified around a certified brand system, substituting an unbranded blanket shifts certification and liability risk to the buyer. Neither answer is universal; the decision should follow the specification environment, not the sticker price.
Why two quotes for "the same" blanket can differ 3x
Beyond format and origin, four quote-level factors routinely explain large gaps between offers that look identical in a product name.
- Density. Per-kilogram pricing rewards low density, but insulation is bought per square meter at a target thickness. A 150 kg/m³ blanket quoted cheaply per kg may cost more per square meter than a 200 kg/m³ blanket quoted higher per kg. Always convert quotes to USD/m² at your required thickness.
- Thermal performance basis. Conductivity is temperature-dependent. A quote referencing 0.020 W/m·K at 25 °C mean is not comparable to one referencing 0.024 W/m·K at 200 °C mean. Ask for the conductivity curve across your operating range, not a single datasheet number.
- Specification honesty. Some low quotes reflect blanket with lower aerogel loading and higher fiber content. Verification costs a few hundred dollars at a third-party lab and is the cheapest insurance in this market.
- Incoterms and volume. FOB China versus DDP destination changes landed cost by 10–25% once freight, duties, and destination handling land in the comparison. Container-load orders versus pallet quantities can differ by 30%+ at the same factory.
How to compare aerogel quotes on equal footing
Convert every quote to the same basis before comparing: USD per square meter at your specified thickness, delivered to your site, at your order volume. Then compare the technical file, not the price sheet.
- Full thermal conductivity curve across your operating temperature range
- Density and thickness tolerance (± tolerance matters for installed performance)
- Hydrophobicity data (contact angle, retention after heat aging)
- Fire performance classification for your jurisdiction and assembly
- Lot traceability and mill certificates
- Lead time, Incoterms, and payment schedule
Suppliers who answer these six items completely tend to be quoting the same product you think you are buying. The directory approach on aerogela's supplier directory helps identify producers and distributors before you request quotations; the supplier evaluation checklist covers the screening steps.
Price trends worth knowing
China's blanket capacity expanded materially through 2024–2026, and spot pricing for standard-grade blanket has trended down even as energy and petrochemical demand grows. Meanwhile, Western brands have held price on certified systems while pushing capacity toward EV thermal-barrier products, where specification is tighter and substitution is slower. The practical consequence for buyers: the factory-to-brand gap is widening, and specification control determines which side of that gap you can access.
FAQ
What does aerogel cost per kg?
Indicatively, USD 3–8 per kg for bulk aerogel blanket factory-direct from China, USD 15–40 per kg for Western brand channels, USD 2–6 per kg for granules in bulk, and USD 50–500+ per kg for research-grade monolithic or powder material. Product format, order volume, and specification depth move quotes within and beyond these ranges.
How much is aerogel blanket per square meter?
Standard 5–10 mm hydrophobic silica blanket from Chinese factories typically lands at roughly USD 4–10 per square meter in bulk. Convert every quote to per-square-meter at your required thickness before comparing, because per-kilogram pricing hides density differences.
Why is aerogel insulation so expensive?
The cost floor comes from silica precursor chemistry and supercritical drying capital. TEOS-based chemistry costs several times water-glass routes, and drying line utilization determines per-unit amortization. High-volume Chinese production on water-glass chemistry is what brought blanket into the single-digit USD per kg range.
Is buying aerogel blanket from Chinese factories safe?
Container-load buyers routinely source factory-direct, with third-party verification (SGS, TÜV, Bureau Veritas) covering specification and lot consistency. Screen suppliers first, verify certificates independently, and start with a sample order before committing volume.
Are aerogel prices falling?
Standard-grade blanket from expanding Chinese capacity has trended down through 2026, while certified brand systems in Western markets have held price. The gap between the two channels is widening.
