Lightweight, silica-based aerogel granules engineered for advanced thermal insulation, fire-resistant material systems, moisture-resistant performance, and specialty integration across industrial and technical applications.
Levron Aerogel Granules are silica-based, nanoporous aerogel particles produced via a proprietary Sol-Gel process. Unlike rigid felt or sheet-format aerogels, granules offer unmatched form-factor flexibility — enabling engineers and product developers to integrate advanced thermal performance into cavities, composites, and custom material systems.
Engineered from high-purity silica precursors through controlled Sol-Gel synthesis, creating a three-dimensional nanoporous network with extraordinary thermal management properties.
50–100 nm pore diameters trap air at the molecular level. With >90% air by volume, granules represent one of the lightest solid material formats available for thermal management applications.
Surface chemistry delivers complete moisture rejection. Granules maintain full thermal performance in humid, wet, or chemically aggressive environments where conventional insulation materials degrade.
Unlike rigid sheets or pre-formed blankets, granules can fill irregular cavities, integrate into composite matrices, and adapt to geometries that other aerogel formats cannot serve.
The granule form gives engineers and product developers a degree of material integration freedom that rigid aerogel formats simply cannot provide. It transforms aerogel from a fixed-geometry product into a configurable insulation medium.
Pour, blow, or pack granules into cavities, channels, and irregular spaces that rigid materials cannot reach. No custom die-cutting or pre-forming required.
Mix granules into polymer matrices, cementitious systems, or resin composites to create hybrid materials with enhanced thermal performance and structural properties.
Control the bulk density and thermal characteristics by adjusting packing configuration — enabling optimized performance for specific application requirements.
Distribute high-performance insulation across large volumes efficiently. Ideal for loose-fill applications, cavity insulation, and bulk thermal management systems where sheet materials are impractical.
Key performance parameters from Levron Aerogel Granule testing. Every number represents measured performance from laboratory evaluation — providing the technical foundation for material selection decisions.
Among the lowest thermal conductivity values of any commercially available granular material. Nano-scale pore confinement physically constrains gas-phase heat transfer — delivering thermal insulation performance per millimeter that far exceeds conventional fillers.
Full operating range from cryogenic to high-temperature environments. Granules maintain structural and thermal integrity across the entire temperature spectrum without degradation.
The nano-porous structure provides meaningful sound absorption — adding acoustic insulation value alongside thermal performance for multifunctional material design.
Non-combustible silica structure resists direct flame exposure up to 650°C. The granules do not contribute to fire load and maintain structural integrity under extreme thermal stress.
Surface chemistry creates complete water and moisture resistance. Unlike conventional insulation that loses 50%+ efficiency when wet, aerogel granules maintain full performance in any humidity condition.
Over 90% of the granule structure is trapped air — making it one of the lightest solid material formats available. Ultra-low density enables massive thermal protection with minimal mass penalty.
Extraordinary internal surface area supports filtration, adsorption, and chemical interaction applications beyond thermal insulation — enabling multifunctional material strategies.
Transparency characteristics can be tuned depending on granule size, packing density, and application context — enabling specialty architectural and translucent insulation concepts.
The extraordinary performance of Levron Aerogel Granules is not achieved by adding more material — it's engineered into the fundamental molecular architecture. A three-dimensional silica network that suppresses heat transfer through three simultaneous mechanisms.
A silica network with 50–100 nm pore sizes — smaller than the mean free path of air molecules at standard conditions. This physically constrains gas-phase heat transfer, making each granule a micro-insulator of extraordinary efficiency.
Conduction minimized by tortuous solid pathways through the silica skeleton. Convection eliminated by molecular-scale air confinement within nano-pores. Radiation scattered within the pore network. All three mechanisms addressed simultaneously.
Overwhelmingly composed of trapped air — one of the lightest solid structures known. For weight-sensitive applications, this means effective thermal protection with minimal mass penalty, even in bulk-fill configurations.
Superhydrophobic surface modification ensures moisture rejection at the granule level. Combined with high porosity and massive surface area, this creates a material platform that serves thermal, acoustic, and filtration functions simultaneously.
Levron Aerogel Granules serve diverse application clusters — from thermal insulation systems to specialty filtration concepts. Each pathway leverages different aspects of the same multifunctional material platform.
Pour or blow granules into wall cavities, ceiling voids, and floor structures for high-performance thermal insulation without pre-forming or custom cutting.
Fill annular spaces around pipes, vessels, and process equipment with aerogel granules for compact, high-temperature insulation in industrial environments.
Integrate granules into lightweight panel systems, modular insulation cassettes, and pre-fabricated thermal barrier assemblies for weight-sensitive applications.
Granules maintain structural integrity up to 650°C, supporting product designs that operate in sustained high-temperature environments.
Use aerogel granules as fire-resistant fill material in protective assemblies, compartment barriers, and thermal partition systems.
Surround thermally sensitive electronics, sensors, and mechanical components with granule-based insulation that blocks conducted and radiated heat.
Adjustable transparency enables specialty architectural and daylighting applications where thermal insulation and light transmission are both required.
Sound absorption up to 25 dB combined with thermal insulation creates dual-function material solutions for noise-sensitive environments.
Granules serve as feedstock for custom-engineered composite materials, advanced coatings, and next-generation thermal management systems developed through R&D collaboration.
700+ m² per gram of internal surface area supports nano and micro particle capture — relevant for advanced filtration media and environmental remediation concepts.
Oleophilic behavior enables oil-water separation and hydrocarbon adsorption applications — a specialty capability enabled by the unique surface chemistry of the aerogel structure.
A structured performance comparison across key parameters — helping engineers and material selectors understand where aerogel granules deliver meaningful advantages over conventional alternatives.

Levron Aerogel Granules exhibit superhydrophobic behavior — complete water and moisture rejection at the particle level. While conventional granular insulation materials absorb moisture over time and lose 50%+ of thermal efficiency, aerogel granules maintain identical performance regardless of humidity, condensation, or direct water exposure.
The silica-based composition provides inherent fire resistance. Granules do not contribute to fire load, cannot sustain flame, and maintain structural integrity under sustained thermal exposure up to 650°C. This makes them suitable for fire-resistant filler concepts, protective barrier assemblies, and thermal partition systems.
The combination of moisture immunity and fire resistance creates material confidence in harsh environments. Systems operating in humid, wet, chemically aggressive, or thermally extreme conditions require insulation that doesn't degrade — aerogel granules deliver both properties inherently, without coatings or secondary treatments.
No performance degradation. No biological growth. No maintenance cycle. Hydrophobic and fire-resistant properties are engineered into the molecular structure — not applied as surface treatments that can wear off or degrade over the system lifecycle.
Levron Aerogel Granules deliver performance across multiple dimensions simultaneously — creating material system value that single-function insulation products cannot match.
The nano-porous architecture is overwhelmingly composed of trapped air — making aerogel granules among the lightest solid insulation materials commercially available. For weight-sensitive product design, this means maximum thermal protection with minimum mass contribution. Every gram of unnecessary weight eliminated through material selection improves system efficiency.
The nano-porous structure absorbs sound energy through viscous dissipation within the pore network. Combined with thermal insulation, this creates a dual-function material that addresses both thermal and acoustic requirements in a single fill — reducing material count and integration complexity.
Extraordinary surface area supports advanced filtration media, adsorption applications, and catalytic support structures. The adjustable transparency characteristic enables translucent insulation concepts for architectural and specialty daylighting applications.
