China Fumed Silica VIP Vacuum Insulation Panel - Class A Fireproof, Low Thermal Conductivity from Reliable Suppliers & Factory
Product Introduction
Core Advantages
Ultra-High Efficiency
Insulation performance is 5-8 times superior to conventional polyurethane. Thinner panels achieve equivalent thermal resistance while substantially saving installation space.
Space Expansion
Integrating VIP panels into refrigerators, freezers, and cold warehouses increases internal usable volume by 20% to 30% without expanding outer dimensions.
Long Service Life
Engineered with a stable core and high-barrier vacuum envelope, ensuring an operational service life of up to 50 years without performance degradation.
Class A Fire Safety
Compliant with DIN ISO4102 Class A non-combustible standards, meeting strict fire safety protocols across construction, logistics, and appliance sectors.
Stable Appearance
Features smooth surfaces and uniform, sharp edges, making it exceptionally flat and convenient for lamination, assembly, and on-site engineering.
Eco-Friendly & Safe
100% recyclable core raw materials; SGS RoHS certified non-hazardous. Fibers are non-respirable, meeting strict WHO occupational health guidelines.
Shock-Resistant
Engineered with high structural integrity to resist daily mechanical impact, ensuring product safety during long-distance shipping and modular assembly.

Frequently Asked Questions (FAQ)
Fumed silica vacuum insulation panels achieve thermal conductivity as low as ≤5 mW/(m·K), delivering 5 to 8 times the insulation performance of polyurethane. This allows manufacturers to achieve equal or superior thermal resistance with significantly thinner profiles.
No. VIP panels rely on an airtight internal vacuum to maintain their ultra-low thermal conductivity. Cutting, puncturing, or drilling the outer membrane will cause loss of vacuum and reduce efficiency. Precise dimensions and irregular shapes must be customized during manufacturing.
Our fumed silica core provides microporous structure stability that protects against aging. Combined with premium high-barrier barrier films, our VIP panels maintain consistent thermal performance for up to 50 years under standard operating conditions.
Our vacuum insulation panels comply with DIN ISO 4102 Class A non-combustible ratings, making them completely safe for exterior wall systems, commercial refrigeration, and mission-critical industrial assemblies.
Yes. We supply standard dimensions (1200x600mm, 1000x600mm) and provide custom fabrication for thicknesses from 5mm to 50mm, as well as complex irregular shapes for customized cold chain, EV battery, and appliance designs.
Yes, our raw materials are fully recyclable, non-hazardous, and SGS RoHS certified. The fumed silica core fibers are non-respirable and fully compliant with World Health Organization (WHO) health criteria.
