Best Vacuum Insulated Panel VIP Factories & Companies

Fumed Silica VIPs utilize a core of synthetic amorphous silica. Due to the nanoparticle configuration (pore sizes typically under 20 nm), the mean free path of remaining air molecules is restricted, limiting gas conduction even at partial vacuum levels (e.g., 1 to 10 mbar). Fumed silica is highly resistant to moisture degradation and has an expected service life of over 30 to 50 years.

Fiberglass VIPs leverage thin glass micro-fibers, which exhibit a larger pore structure. They require a much higher vacuum level (0.1 mbar or lower) to achieve their optimal initial thermal conductivity (~0.0015 W/m·K). Without getters (chemical moisture absorbers) and heavy-barrier envelopes, fiberglass VIPs are more vulnerable to vacuum drop-offs over time.

No, VIPs cannot be cut, nailed, or drilled under any circumstances. The thermal performance relies entirely on the hermetic seal of the multi-layer barrier foil envelope maintaining an internal vacuum. Puncturing the envelope releases the vacuum, causing the internal pressure to equalize with atmospheric pressure.

This causes the thermal conductivity to spike to approximately 0.020 W/m·K (similar to standard non-vacuum core parameters). All panel sizes must be pre-planned, modeled, and custom-manufactured to the exact specifications of the envelope system.

Over years of service, microscopic amounts of water vapor and atmospheric gases (nitrogen, oxygen) slowly permeate through the multi-layer barrier foil joints. Getters are chemical alloys or active materials integrated within the core matrix that react with and bind these gases.

Simultaneously, internal desiccants capture incoming water vapor. This internal chemical capture keeps the internal vacuum pressure stable over decades, preserving the panel's low thermal conductivity.

Procurement officers typically specify three critical metrics:

• Initial Thermal Conductivity: Generally targeted below 0.004 W/m·K for fumed silica systems.
• Compressive Strength: Crucial for panels embedded in container bases or high-load floor assemblies. Must resist deformation under structural weight.
• Barrier Film Performance (WVTR): Water Vapor Transmission Rate, which measures the efficiency of the protective foil layer. Under 0.01 g/(m²·day) is highly desired.

Modern structural engineering demands consistent insulation across the entire envelope. Pairing vacuum insulated glass (VIG) for transparent glazing sections with vacuum insulation panels (VIPs) for opaque wall panels eliminates thermal bridging.

This combination provides continuous thermal performance across the building envelope, maximizing interior space and enabling structures to achieve Passive House standards.
