Explore Details →Traditional building insulation materials such as extruded polystyrene (XPS), polyurethane (PU), and mineral wool rely on trapping static air within their cellular structures. While effective, their thermal performance is physically limited by the thermal conductivity of the gas molecules within those structures ($\approx 0.024 \text{ W/(m}\cdot\text{K)}$). Advanced window insulation boards and vacuum insulation panels (VIPs) bypass this thermodynamic threshold. By evacuation, gas conduction and convection are reduced to near zero.
Our fumed silica VIP core systems consist of a pressed nanoporous silica powder matrix. The average pore diameter of fumed silica is roughly 30 to 100 nanometers. This is smaller than the mean free path of air molecules at atmospheric pressure (approximately 70 nm). Consequently, even with minor vacuum changes, heat transport is constrained by the Knudsen effect. This technology enables a thermal conductivity rate ($\lambda$-value) of less than $0.002 \text{ W/(m}\cdot\text{K)}$, providing up to ten times the insulating power of standard foams of identical thickness.
Selecting the correct insulation core is vital for longevity, mechanical load resistance, and cost efficiency. The table below details key metrics for engineering consideration:
| Insulation Material | Thermal Conductivity (W/m·K) | Lifespan (Years) | Fire Resistance Class | Moisture Sensitivity |
|---|---|---|---|---|
| Fumed Silica Core VIPs | 0.002 – 0.004 | Up to 50 Years | Class A (Non-combustible) | Low (Protected by multi-layer films) |
| Fiberglass Core VIPs | 0.0015 – 0.003 | 15 – 25 Years | Class A (Non-combustible) | High (Degrades if vacuum is lost) |
| Polyurethane (PU) Foam VIPs | 0.007 – 0.012 | 20 – 30 Years | Class B1 / B2 | Moderate |
| Extruded Polystyrene (XPS) | 0.030 – 0.040 | 30 – 50 Years | Class B1 / B2 | Very Low |
| Vacuum Insulated Glass (VIG) | 0.05 – 0.07 (System) | 25+ Years | Excellent (Tempered Glass) | None |
Window frame and perimeter installations are common vectors for structural thermal bridging. When cold outdoor air meets uninsulated window openings, localized condensation can occur, leading to structural rot and indoor mold growth. Applying thin, high-performance window insulation boards directly to the window reveal minimizes this risk.
By combining fumed silica core VIPs with tempered vacuum insulated glass (VIG), designers can optimize window perimeter detailing. The glass panes are separated by a micro-spacer grid under high vacuum, while the surrounding framing is lined with tailored nano-microporous blankets. This configuration creates a continuous, high-performance thermal envelope, eliminating the thermal bridging common in standard window frames.

Our manufacturing base is in Nanchong City, Sichuan Province. This facility is one of China's largest comprehensive production centers for vacuum technology application products.
Specialized dimensions beyond ANSI/ASME/DIN standards, manufactured to custom customer technical drawings.
Square, oval, and complex shapes, including large-scale diameters exceeding 60 inches and micro-precision flanges.
Manufactured to strict design tolerances using certified high-purity raw materials.
High-performance vacuum insulation panels require clean-room manufacturing and precise process control. As a subsidiary of CBVAC Group, Zerothermo Technology utilizes a vertically integrated supply chain, from raw material formulation to final automated testing.
Our Nanchong manufacturing base handles the mixing, forming, and high-pressure sintering of raw silica cores. An automated core handling system transfers the boards directly to chamber sealers under ultra-low pressure environments. This automated process minimizes core exposure to ambient humidity, which can affect the lifetime performance of the panels. Combined with local material sourcing, this layout enables us to provide cost-effective options without sacrificing technical parameters.
