Explore our top-tier vacuum and high-temperature thermal barrier products engineered to maximize structural energy efficiency.
In modern sustainable construction, the building envelope dictates up to 50% of a structure's operational carbon footprint. Traditional Structural Insulated Panels (SIPs), while representing a milestone in prefab building efficiency, have historically relied on expanded polystyrene (EPS), extruded polystyrene (XPS), or polyurethane (PU) foam cores. Under the pressure of global carbon-neutrality mandates, these legacy cores are hitting their physical limits: achieving passive house thermal envelope metrics (U-values below 0.15 W/m²K) requires panel thicknesses exceeding 300mm.
"By integrating vacuum engineering with high-performance cores, we can reduce panel thickness by up to 70% while maintaining the exact same thermal barriers, bypassing the structural limits of traditional building models."
Zerothermo Technology Co., Ltd. (a subsidiary of CBVAC Group) introduces a new paradigm: Vacuum-Enhanced & Nano-Microporous Core Structural Insulated Panels (VIP-SIPs). By combining structural durability with vacuum insulation panels (VIPs), these hybrid systems provide an ultralow thermal conductivity of 0.004 W/m·K—five to seven times more efficient than traditional EPS/XPS foam cores. This breakthrough enables architects, builders, and B2B procurement professionals to achieve the highest R-values without expanding wall envelopes or sacrificing usable indoor area.
| Core Material Type | Thermal Conductivity | Required Thickness (R-40) | Fire Safety Rating |
|---|---|---|---|
| Fumed Silica VIP Core | 0.004 W/m·K | 40 mm | Class A1 / Non-combustible |
| Nano-Microporous Core | 0.016 W/m·K | 100 mm | Class A1 / Extreme Temp |
| Polyurethane (PU) Foam | 0.022 W/m·K | 160 mm | Class B1 / Combustible |
| Traditional EPS Foam | 0.035 W/m·K | 260 mm | Class B2 / Highly Combustible |
Analyzing the global shift toward net-zero building regulations, prefabrication, and material optimization.
Regulatory frameworks such as the European Green Deal, California's Title 24, and China's "Dual Carbon" targets are forcing developers to seek materials that eliminate thermal bridging entirely. Structural Insulated Panels provide a continuous thermal envelope, but traditional spline connections still allow heat leakages. The next-generation VIP-SIP systems utilize engineered overlap systems and vacuum-sealed joints to eliminate thermal bypass, enabling projects to reach passive building metrics with ease.
In high-density cities where land cost is premium, wall thickness translates directly to usable square footage. Traditional double-stud walls insulated to passive standards can be 400mm thick, eating up 5% to 8% of a building's footprint. Transitioning to vacuum-core structural panels reduces wall thickness to 150mm while delivering superior R-values. This spatial recovery yields significant financial returns for commercial real estate developers, offsetting the initial CAPEX of advanced vacuum panels.
Traditional foam-based SIPs pose safety hazards during fires, releasing toxic fumes and accelerating flame spread. As high-rise modular construction expands globally, Class A fire-rated structural composites are no longer optional. The integration of inorganic nano-microporous cores and fumed silica VIP cores inside metallic or magnesium-oxide (MgO) sheathings offers a dual benefit: unmatched structural thermal control and standard-setting fire protection.
Key performance parameters that international B2B buyers must evaluate when selecting a panel manufacturer.
Vacuum insulation cores must maintain integrity over the building's lifecycle. Ensure your manufacturer utilizes multilayer metallized PET barrier films with high gas barrier performance, keeping degradation below 5% over 50 years.
For structural applications, panels must withstand high compression. Fumed silica cores offer exceptional structural stability under compressive loads, preventing core compression and subsequent panel deflection.
Unlike traditional foam SIPs, vacuum-insulated cores cannot be cut or modified on-site without puncturing the vacuum seal. B2B suppliers must have precise CNC pre-fabrication, molding, and shape-tailoring capabilities.

No. Unlike traditional EPS or XPS foam SIPs, which can be trimmed with circular saws on-site, the core vacuum insulation panels (VIPs) are hermetically sealed under high vacuum (< 1 mbar). Puncturing, cutting, or drilling into the panel core will release the vacuum, causing the thermal conductivity to rise from 0.004 W/m·K to approximately 0.020 W/m·K. Therefore, VIP-SIP systems must be manufactured to exact dimensions based on CNC drawings. All conduit routes, connection slots, and penetrations must be pre-engineered during the design phase.
Fumed silica core VIPs are highly recommended for permanent building structures. While fiberglass VIPs offer a slightly lower initial thermal conductivity (0.002 W/m·K), their performance degrades over time if moisture or air molecules slowly permeate the barrier film. Fumed silica, with its microporous structure, resists performance loss even if vacuum levels decay, maintaining low thermal conductivity (around 0.018-0.020 W/m·K at ambient pressure). Additionally, fumed silica is inorganic, non-combustible, and provides excellent Class A1 fire protection.
Our vacuum insulation panels are designed to match the typical 50-year service life of building envelopes. We utilize multilayer barrier films with aluminum layers (or EVOH co-extrusions) to minimize gas transmission rates. Under typical structural installation conditions, where the panel is protected from mechanical damage, the vacuum decay is extremely slow, ensuring the system retains its thermal performance over the building's lifespan.
Thermal bridging is mitigated through engineered edge joints. We utilize stepped lap designs, ship-lap joints, or high-performance elastomeric foam inserts at panel junctions. In premium assemblies, we place overlapping layers of thinner VIPs to cover the seams, ensuring a continuous thermal barrier across the envelope.
Our core materials and composite panel assemblies undergo rigorous testing. The inorganic fumed silica core is non-combustible and complies with Class A fire ratings. Our complete products undergo tests for compressive strength, thermal resistance, and long-term aging under ISO 9001 and CE frameworks, meeting international building code requirements.
