Explore our top-tier vacuum insulation panels and thermal solutions designed for maximum efficiency in cold chain, construction, and high-temperature industries.
Industry Insights: Vacuum Insulation Panels (VIPs) represent the pinnacle of modern thermal engineering, achieving a thermal conductivity (K-value / Lambda value) of less than 0.004 W/(m·K). This performance is roughly 5 to 10 times more efficient than traditional insulation materials like polyurethane (PU) foam, expanded polystyrene (EPS), or rockwool.
The core mechanism relies on the elimination of gas conduction. Heat transfers through three main vectors: solid conduction, gas convection/conduction, and radiation. By placing a nanoporous core material—such as fumed silica or ultra-fine fiberglass—within a high-barrier envelope and evacuating the gas down to a target pressure (typically between 1 to 10 mbar), gaseous heat transfer is virtually eliminated. This enables unprecedented space savings and thermal security across critical infrastructure projects, cold chain logistics, and high-performance building systems.
Fumed silica consists of amorphous silicon dioxide nanoparticles sintered into larger structures with pore sizes ranging from 10 to 100 nanometers. This pore size is smaller than the mean free path of air molecules at atmospheric pressure, ensuring that even if vacuum degradation occurs over time, the thermal conductivity remains exceptionally low (around 0.020 W/m·K).
Fiberglass core VIPs offer a lower initial manufacturing cost and slightly better initial thermal conductivity under high vacuums (<0.1 mbar). They are widely used in commercial refrigeration units, deep-freeze refrigerators, and domestic appliances where structural containment mitigates puncture risks.
The lifespan of a VIP is determined by the gas transmission rate (GTR) of its envelope. Multiple layers of metallized PET and aluminum foil protect the core vacuum against moisture ingress and atmospheric gas diffusion, securing an operational lifetime of up to 30 to 50 years.

By integrating advanced NEG materials inside the core panel, we can chemisorb active outgassing molecules (nitrogen, carbon dioxide, oxygen). This extends vacuum lifetime from 15 to over 60 years in static infrastructure applications.
Transitioning fumed silica extraction to bio-based and recycled silica gel matrixes. Our target is to reduce the carbon footprint of manufacturing VIP panels by 40% while preserving ultra-low Lambda values.
Developing embedded wireless IoT sensors that monitor vacuum level degradation over real-time networks without breaching the high-barrier envelope layers. Crucial for large cold chain storage complexes and vaccine transports.
