VIBs (Vacuum Insulation Panels / Boards) are very high insulation boards manufactured with high quality microporous core encapsulated and vacuum sealed in impermeable high gas barrier film under vacuum. The core material is fire resistant fire class A1 noncombustible Fumed Silica board and an opacifier to block the infrared radiation. These boards are available in ready to use sizes only.

A vacuum, or the absence of air, has no thermal conductivity. Only radiation can pass through a vacuum. These boards give outstanding thermal conductivity for the thinnest possible solution and are considered the next generation of insulation products.

Applications

• Vacuum Flask, Cool Devices, Refrigerators and freezers

• Temperature controlled packaging or Thermal packaging (Medicine transport boxes, etc.)

• Appliance (Water boiler, etc.)

• Automotive (train, ship, airplanes, etc.)

• Building Insulation: Facades, Walls, Floor & Roof, Doors,

Windows Insulation, Cold storages, and cold rooms.

 

Advantage

• Highest insulation material thermal conductivity < 0.005 W/mK.

• Lowest heat loss and highest barrier to heat penetration into cold environment.

• Lowest insulation thickness achieved resulting in increasing and saving space.

• High R-value (4.8 m2K/W per 20mm)

• Lightweight & thinnest insulation available

• Environmentally safe, contains no respirable fibres

• Very high service life upto 60 years.

What is VIP (Vacuum Insulation Panel?

Vacuum is absence of air and has zero thermal conductivity. Only radiation can pass through a vacuum. Vacuum Insulation Board gives outstanding thermal insulation for the thinnest possible solution and are considered the next generation of insulation products.  A vacuum insulated panel (VIP) is a form of thermal insulation consisting of a gas-tight enclosure surrounding a rigid core, from which the air has been evacuated. It is used in building construction, refrigeration units, and insulated shipping containers to provide better insulation performance than conventional insulation materials.

It has best features in term of insulation performance:

Highest Thermal Efficiency

  • VIPs provide an insulating performance that has a significant improvement over other commonly available insulation materials. Because they rely on the insulation property of a vacuum they can easily achieve low U-values with minimum thickness.

  • Ideal for upgrading insulation during refurbishment. When upgrading thermal performance in an existing building it can often be hard to fit more insulation without adding to construction thickness, which might reduce the amount of daylight into the building or extending the eaves but with VIPs this can be overcome due to the thin nature of the insulation.

  • Reliable long term performance over life time of building.

  • Fits in tight spaces for new builds. VIPs are the perfect solution in areas where lack of construction space or thickness is an issue, for example better insulation can be achieved on a floor without the need to raise skirting boards or radiators and without changing the floor level; excavating the floor or adding in a step at a doorway when adding in a new extension or balcony.

  • Sleek design. Having to incorporate large amounts of space for insulation can often compromise the look and feel of a building, but with VIPs, the same levels of insulation can be achieved which much thinner insulation. Difficult areas, such as dormer windows or balconies which may have gone uninsulated because of lack of space available, can be insulated without having to alter the design of the building.

 

Manufactured with High Quality Components

  • Membrane walls, used to prevent air from entering the panel.

  • A panel of a rigid, highly-porous material, such as fumed silica, aerogel, perlite, or glass fiber, to support the membrane walls against atmospheric pressure once the air is evacuated.

  • Chemicals (known as getters) to collect gases leaked through the membrane or off gassed from the membrane materials. These are added to VIPs with glass-fiber or foam cores, because cores with bigger pore size require a higher vacuum (less than about 1 mbar) during the planned service life.

6 to 10 Times Lower Thickness Required

The thermal resistance of VIPs per unit thickness compares very favourably to conventional insulation. For instance, standard mineral wool has a thermal conductivity of 0.044 W/(m·K),[6] and rigid polyurethane foam panels about 0.024 W/(m·K). This means that VIPs have about one-fifth the thermal conductivity of conventional insulation, and therefore about five times the thermal resistance (R-value) per unit thickness. Based on a typical k-value of 0.007 W/(m·K), the R-value of a typical 25-millimetre-thick (1 in) VIP would be 3.5 m2·K/W (20 h·ft2·°F/BTU). To provide the same R-value, 154 millimetres (6 in) of rockwool or 84 millimetres (3 in) of rigid polyurethane foam panel would be required.

Limitations with Vacuum Insulation Panels

VIP products cannot be cut to fit as with conventional insulation, as this would destroy the vacuum, and VIPs in non-standard sizes must be made to order, which also increases the cost. So far this high cost has generally kept VIPs out of traditional housing situations, However, their very low thermal conductivity makes them useful in situations where either strict insulation requirements or space constraints make traditional insulation impractical. VIP performance is also temperature dependent with increasing temperature, conductive and radiative transfer increase. These panels cannot operate much above 100 °C (212 °F) due to the adhesive used to seal the thin envelope. 

Applications of Vacuum Insulation

VIPs are a highly insulating material that has been implemented into many appliances, such as refrigerators and freezers, and the transportation industry where refrigeration is required. These panels also give extremely high performance to keep building maintaining thermal comfort in extreme cold and hot areas.
