Project Type: Residential exterior wall envelope insulation
Material Applied: Nano Tech aerogel insulation blanket, 6mm nominal thickness
Buyer Profile: Building material distributor / EPC contractor sourcing for a mid-to-high-rise residential development
Most inquiries for an aerogel insulation blanket don't start with the material — they start with a constraint our already knows they can't solve with conventional options. In this project, the design team needed to hit a stricter energy-efficiency target without increasing the exterior wall's overall thickness, because the building's floor plan and setback lines were already fixed. That rules out adding more EPS board or rock wool: both would either blow the wall thickness budget or fail fire code at the required R-value.
The project team evaluated the two standard categories before contacting us:
Organic boards (EPS, XPS, polyurethane) — cheap and easy to install, but poor flame retardancy makes them a liability in residential fire code review, and multiple developers in this market have had approvals delayed over exactly this issue.
Inorganic mineral wool — fire-safe, but its low hydrophobicity means water absorption over the building's lifespan degrades thermal performance and risks mold in the wall cavity.
Neither could deliver Class A fire performance and long-term water resistance in the thickness the project had available. (For the full technical comparison our team walks buyers through, see our Building Construction application page.)
We supplied our FMC200 aerogel insulation blanket, a compact, flexible silica aerogel felt engineered for exactly this kind of space-constrained application. At just 6mm, it replaced a wall buildup that would otherwise have required 3-5x the thickness in conventional material to hit the same thermal target — freeing up usable floor area across every unit in the building without redesigning the envelope.
Key reasons this thermal insulation blanket was selected over both organic and inorganic alternatives:
Thermal conductivity as low as 0.016 W/(m·K), allowing the thinnest layer in the wall assembly to do the most thermal work
Class A fire rating (inorganic) — no fire-code exception process required
Overall hydrophobicity — the blanket sheds water rather than absorbing it, so thermal performance doesn't degrade over the building's service life
Integrated sound insulation, improving unit-to-unit and exterior noise performance as a side benefit the developer didn't have to source separately
Easy to cut and construct on-site, which matters more to installation crews than any spec sheet number — most rock wool and PU crews had never handled aerogel felt before this project, and on-site cutting and fitting matched standard tools and timelines
For international buyers, the product spec is only half the sourcing decision. What we walked this buyer's procurement team through:
Fire and thermal test reports for the specific batch and thickness being shipped, not generic datasheet numbers
Custom roll width and thickness options — our aerogel insulation blanket line is available from 3mm to 10mm with roll widths up to 1500mm, so wall assemblies don't have to be redesigned around a fixed product size
Private label / OEM packaging for distributors reselling under their own brand
Factory-direct pricing and lead times, since this material is manufactured at our own 32,000 sqm production facility rather than sourced through a trading intermediary
Nano Tech has been manufacturing silica aerogel and its composites since 2004, and was the lead drafting organization for China's national standard on reinforced nanoporous aerogel insulation products — meaning the compliance documentation buyers request isn't an afterthought, it's built into how we test and certify every production run. With 28 invention patents, an in-house R&D team, and an annual output capacity of 8,000,000 square meters, we're able to support both one-off project orders and the recurring, multi-project supply agreements that distributors and EPC contractors typically need for residential portfolios.
If you're evaluating a wall insulation material for a project with a fixed envelope thickness, a fire-code constraint, or a moisture-exposure risk that conventional board or mineral wool insulation can't solve, our team can run the same thickness-and-performance comparison for your project spec.
