Our Vacuum Insulation Panel (VIP) represents the pinnacle of thermal management technology. By sealing a fumed silica core within a high-barrier multi-layer film and creating a vacuum environment, we have achieved an extraordinary thermal conductivity of 0.002 W/m.K. This ultra-thin solution provides maximum thermal protection while occupying minimal space, making it the superior choice for high-end refrigeration, cold chain logistics, and energy-efficient architecture.
Description
As a recognized leader in nanoporous materials with over 15 years of industry experience, Hebei Woqin provides high-vacuum solutions that redefine the limits of thermal insulation. Our Vacuum Insulation Panels (VIPs) achieve an industry-leading thermal conductivity of 0.002 W/m.K, offering unparalleled protection for temperature-sensitive applications.
10x Thermal Efficiency: Features a certified 0.002 W/m.K thermal conductivity, which is nearly ten times more efficient than traditional polyurethane (PU) or mineral wool insulation.
Maximum Space Optimization: Our ultra-thin profile replaces 200mm of traditional insulation with just 20mm of VIP, increasing internal storage capacity by up to 30% in shipping containers and buildings.
20-Year Service Life: Engineered with advanced multi-layer barrier films and proprietary edge-sealing technology to ensure vacuum stability and peak performance for decades.
Superior Fire Safety: Fully compliant with international non-combustibility standards, meeting EN 13501-1 Class A2 and ASTM E84 requirements.
Eco-Friendly Core: Constructed from non-toxic, recyclable fumed silica, ensuring a sustainable solution for green building and pharmaceutical logistics.
The "Space = Money" ROI Metric: In commercial cold chain and architectural retrofits, insulation thickness eats into your profitable volume. By upgrading to Woqin 0.002 VIPs, a standard refrigerated container gains up to 30% more cargo space. For international shipping or high-value pharmaceutical logistics, the extra cargo capacity pays for the VIP material investment within the first few transit cycles.

Cold Chain and Pharmaceutical Logistics: The gold standard for transporting vaccines, biological samples, and fresh food in temperature-controlled containers and refrigerated trucks.
Medical and Laboratory Infrastructure: Providing high-performance thermal barriers for ultra-low temperature freezers (-80°C) and specialized laboratory equipment.
Energy-Efficient Architecture: Ideal for exterior walls, roof systems, and floor heating in passive houses and high-end architectural projects where space is at a premium.
Premium Home Appliances: Enhancing the energy efficiency ratings of high-end refrigerators, freezers, and water heaters while maximizing internal volume.
Many cheap VIPs on the market use standard fiberglass cores, which degrade and lose their vacuum within 5 years. Hebei Woqin specializes in Fumed Silica VIPs. Fumed silica acts as a natural desiccant, absorbing micro-moisture to maintain the absolute vacuum state, guaranteeing the 20-year service life required by the European construction sector and critical cold-chain assets.
Each Vacuum Insulation Panel undergoes a 100% helium leak test and thermal conductivity verification before shipping to ensure absolute vacuum integrity.
Custom Sizes: Standard thicknesses of 10–50 mm, with custom dimensions available up to 1200 × 600 mm.
Precision CNC Shaping: We can produce 2D/3D custom shapes with pre-cut holes for piping and electrical conduits.
Q: What core materials do you use in your VIPs?
A: We offer two specialized tiers. Our premium Fumed Silica cores are designed for architecture and cold-chain containers requiring a 20-year lifespan. For high-end home appliances (like refrigerators) where cost-efficiency and a 10-year lifespan are sufficient, we supply high-quality Glass Fiber cores. We also offer Aerogel-composite cores for unique thermal demands.
Q: Can you manufacture non-rectangular or curved panels?
A: Yes. We specialize in bespoke manufacturing. Based on your CAD drawings, we can produce curved panels for wrapping pumps and tanks, as well as irregular shapes to fit specific equipment geometries.
Q: Can Vacuum Insulation Panels be trimmed or cut on-site?
A: No. Any puncture or cutting will destroy the internal vacuum state, instantly turning the panel into standard insulation. Because we offer 100% custom shaping at our factory, we ensure every panel fits your wall or device perfectly without the need for on-site adjustment.
Q: What is the maximum operating temperature for VIPs?
A: Vacuum Insulation Panels are exceptional for deep cold (-80°C) up to moderate heat (+80°C). However, the outer barrier film will melt at extreme temperatures. If your project requires insulation for 100°C to 1000°C (such as industrial exhaust or steam pipes), please explore our [ High-Temperature Aerogel Blanket Solutions].
