An Aerogel Sheet is a flexible blanket or rigid panel infused with nanoporous aerogel—most commonly silica—engineered to deliver exceptional thermal insulation at minimal thickness. By trapping air in pores smaller than the mean free path of gas molecules, an Aerogel Sheet suppresses convection and reduces conduction, achieving very low thermal conductivity in a lightweight format.
Slim profile for tight spaces where conventional insulation won’t fit
High thermal performance-to-weight ratio
Hydrophobic and breathable options for moisture-managed assemblies
Cuttable and conformable around complex shapes
Aerogel’s pores are nanometer-scale. Gas molecules collide more with pore walls than each other (Knudsen effect), which slows heat transfer. The solid silica network is sparse, further limiting conduction, while the microstructure scatters infrared radiation.
Thermal conductivity (λ): commonly in the 0.013–0.020 W/m·K band, grade-dependent
R-value per inch: often higher than conventional mineral wool or foam of the same thickness
Service temperature: many grades operate from sub-zero conditions up to several hundred °C
Interior retrofits where wall thickness and floor buildup must stay minimal
Thermal bridges at lintels, window reveals, balconies, and steel members
Historic façades needing discreet, reversible insulation
Duct wrap to cut heat gain/loss without oversizing chases
Cold piping and equipment where condensation control is critical
High-temperature pipes, tanks, and process equipment with space or weight limits
Oil & gas lines requiring stable performance under compression and vibration
EV battery packs and enclosures for thermal buffering
Automotive firewalls, cabins, and cargo areas where light weight is essential
Flexible blankets (3–10 mm typical) for wraps and irregular surfaces
Rigid or semi-rigid panels for flat substrates and impact resistance
Hydrophobic Aerogel Sheet resists liquid water while allowing vapor diffusion, helping assemblies dry out and reducing mold risk.
Higher-density sheets resist compression under cladding or fasteners; choose based on expected loads and contact pressures.
Many Aerogel Sheet products are non-combustible or low-smoke forming; verify ratings (e.g., Euroclass/ASTM) for your project.
Clean, dry, and sound surfaces; prime or level as needed to maximize contact and reduce air gaps.
Cut with a sharp knife or shears; use compatible adhesives, mechanical fixings, or tapes per the manufacturer’s guidance.
Stagger joints and tape seams to minimize thermal bypass.
Multiple thin layers can outperform a single thick layer by offsetting joints.
Integrate with vapor control layers based on climate and assembly design.
Aerogel Sheets maintain performance under moderate compression; avoid point loads that create thermal bridges.
Hydrophobic grades repel liquid water, but protect edges in exposed conditions.
UV exposure can degrade facings—clad or cover when used outdoors.
Dust off gently; replace only if physically damaged or permanently compressed.
Aerogel Sheet materials cost more per square meter than bulk insulations.
Savings often come from thinner assemblies, less rework on site constraints, improved energy performance, and extended service life.
High-value in space-limited retrofits, thermal-bridge remediation, and downtime-sensitive industrial work where speed and thickness matter.
Check for air gaps, crushed areas, or thermal bypass at seams; re-tape and add a second layer at critical edges.
Confirm dew point analysis, ensure airtightness, and pair the Aerogel Sheet with correct vapor control strategy.
Increase contact area of fixings, add continuous backing boards, or step up to a higher-density Aerogel Sheet.
For thermal bridges and reveals, 5–10 mm is common; for pipes or ducts, size to reach target surface temperature and dew-point control, then refine via calculation.
Yes, typical silica-based Aerogel Sheets are inert and low-VOC when properly faced; always review the product’s safety data and certifications.
It can in many space-restricted areas, but whole-assembly design may still combine Aerogel Sheet with other materials for cost and acoustic performance.
It generally offers higher insulation per thickness, better performance under compression, and improved moisture behavior—at a higher material cost.
An Aerogel Sheet delivers top-tier insulation in places standard materials can’t fit, leveraging nanoporous aerogel to slash heat transfer with minimal thickness and weight. Choose the appropriate format, density, and moisture/fire ratings, install with sealed seams and proper layering, and you’ll unlock reliable, space-efficient thermal performance across buildings, industry, and transport.
