Explore our flagship series of vacuum insulation panels and flexible thermal blankets engineered to achieve the lowest thermal conductivity coefficients in the industry.
Nano-microporous thermal insulation represents the absolute frontier of modern materials science, particularly in thermal energy containment. Microporous insulation materials rely on the Knudsen Effect to limit gaseous conduction. When the mean free path of gas molecules within a porous structure is larger than the diameter of the pores themselves, the gas molecules collide with the pore walls far more frequently than they collide with each other. This virtually eliminates convective heat transfer through the gas phase.
By combining ultra-fine fumed silica particles, specific opacifiers (such as silicon carbide or titanium dioxide to scatter infrared radiation), and binding fibers, we produce a board containing micro-cavities averaging 20 nanometers in diameter. With a thermal conductivity rate as low as 0.015 W/(m·K) to 0.020 W/(m·K) at room temperature, our boards outclass traditional materials like ceramic fiber, mineral wool, and polyurethane foam by up to five times in efficiency.
Currently, the global demand for energy-efficient industrial insulation is growing rapidly due to strict carbon reduction mandates (such as Europe's ESG directives and China's "dual-carbon" goals). Industrial kilns, high-temperature smelting units, sub-sea pipe-in-pipe systems, and battery storage systems all require compact, high-efficiency insulation barriers. Conventional insulation requires thick walls that limit spatial volume; microporous insulation panels solve this space-efficiency challenge.
| Insulation Type | Avg. Density (kg/m³) | Thermal Cond. @ 800°C (W/m·K) | Max Temp (°C) | Primary Industry Advantage |
|---|---|---|---|---|
| Microporous Board | 280 - 450 | 0.023 - 0.029 | 1000°C | Ultra-low thickness, zero flame spread |
| Ceramic Fiber Board | 260 - 320 | 0.120 - 0.160 | 1260°C | High temperature limits but poor thermal barrier |
| Calcium Silicate Board | 240 - 270 | 0.130 - 0.180 | 1000°C | High structural strength, high thickness penalty |
Our ongoing material science roadmap focuses on enhancing both structural integrity and hydrophobicity. Because microporous boards are composed of dry, pressed fumed silica, exposure to moisture can cause capillary degradation of the core structure. Zerothermo Technology integrates advanced silicone coatings and high-vacuum foil barriers to ensure our panels remain completely dry and effective in challenging environments, such as marine transport and building envelopes.
We are also researching composite inorganic binders that allow our flexible nano blankets to wrap around complex pipelines without generating irritating dust or fracturing the silica matrix. This material flexibility is critical for new energy vehicle (NEV) battery pack compartments, where thin profiles and vibration resistance are non-negotiable requirements.

Expert answers regarding nano-microporous mechanisms, physical parameters, and deployment instructions.
Nano-microporous boards are manufactured using fumed silica matrices that create physical pore diameters averaging less than 20nm. This is smaller than the mean free path of air molecules at standard atmospheric pressure, reducing gas phase heat transfer to near zero. Traditional materials cannot restrict gas molecule mobility at this scale, resulting in thermal conductivities 3 to 5 times higher.
Standard raw microporous boards can be mechanically cut using woodworking tools. However, for boards encapsulated within vacuum insulation panels (VIPs) or custom high-temperature fabrics, any cutting will compromise the barrier film and void the vacuum. We offer custom sizing and shape routing directly during our fabrication process to match complex configurations.
Our boards are designed for continuous operating temperatures up to 950°C, and peak exposure up to 1050°C. Since fumed silica and inorganic opacifiers have very high melting thresholds, the board maintains its structural integrity without outgassing, shrinking, or thermal degradation over decades of use.
Fumed silica is hydrophilic. To prevent structural changes or loss of thermal efficiency from water absorption, we utilize advanced hydrophobic chemical treatments during core manufacturing, or fully encapsulate the core material in specialized barrier films and vacuum envelopes.
Flexible nano mats are ideal for complex geometries, such as pipes, valves, gas turbines, and battery thermal barriers in electric vehicles. The flexibility allows the insulation to bend without cracking, preventing the thermal bridging that occurs when using rigid insulation boards on curved surfaces.
By delivering high thermal resistance with minimal thickness, our vacuum insulation panels allow architectural designs to maximize usable indoor space while lowering heat loss. This significantly reduces active heating and cooling demands, helping projects qualify for high-tier LEED certifications.
