Vacuum insulation panels (VIP for short)
vacuum insulation panels (VIP for short), originated from space technology, Environmentally friendly, high efficiency, energy saving, currently the most advanced efficient thermal insulation material in the world.
- The vacuum insulation panel(VIP) is vacuum forming panel for heat insulation, which inner core materials are sealed by the aluminum foil and high barrier film.
- Effectively avoid air convective transfer, significantly reduce thermal conductivity, the minimum value below 0.006 w/m.k.
- Without any ODS materials(ozone depleting substances)

(Note: if panels size is not fit for bigger area, double layer overlying way can be applied.)
Material composition
The core material is Nano-grade fumed silica reinforced inorganic fiber, and added Aerogel, activation factors and other necessary ingredients.
The high barrier film is composted by PE films, aluminum foils and glass fiber layers.
Application fields
High-end devices, electric appliance fireproofing and insulation,
refrigerators, freezers and other household appliances industry,
reefer containers and cold storage system, integrated housing and building walls.
Heat preservation principle
Heat transfer mechanisms: conduction, convection and radiation.
Influencing factors: air and moisture.
VIP insulation principle
Vacuum insulation: maximize internal vacuum degree and completely cut off air convection.
Conduction blocking: Nano-grade fumed silica with high thermal resistance ability can reduce heat conduction effectively.
Reflection absorption: aluminum foil material for the surface can reflect heat radiation, honeycomb structure of Nano-grade silica can absorb heat reflection.
Moisture-proof and seepage-proof: high barrier film can isolate air infiltration and moisture accumulation.

(Note: if VIP is in damaged condition, the thermal conductivity of bare core panel is around 0.017W/m.k)
Function superiority
- Excellent insulation performance: the minimum thermal conductivity can reach 0.006W/m.k or below.
- Light unit weight: the weight of every square meter on wall is less than 10 kg (including accessories); after the installation it is not easy to fall off.
- High efficiency of construction: it can be directly pasted like ceramic tiles; reduce environmental hazards for human body,;shorten construction period and save costs.
- High safety: main insulation materials are inorganic heat preservation, fireproofing and anti-flaming.
- Non-toxic, green, environmental protection: all natural inorganic materials can be safely used in
- the production and living.
- Low maintenance cost: lightweight, durable, strong, impervious, during common use no need to maintain.
- High space utilization: under the same effect greatly decrease thickness of material to 20%-25% of traditional materials, and maximize the effective using space.
- Long service life span: stable chemical components resist to temperature, climate and environment changing; high barrier film gets high ability to resist decomposition; panel can be used
- bare and its life span is more than 30 years.
