Thermal insulation is used to maintain proper temperature control and reduce the transfer of thermal energy between objects and spaces. Maintaining temperature levels without some degree of heat loss is impossible, however, vacuum insulation panels can significantly reduce the effects of thermal transfer.

Why VIP is a better choice for thermal insulation?

Vacuum insulation panels (VIP) are the optimal choice for the transportation of heat sensitive products as well as insulation of residential and commercial appliances. Some of the main highlights of VIP include low thermal conductivity (increased R Value), improved product life, and an environmentally sound construction. VIP are also a thin and lightweight alternative to the bulk created by conventional insulation materials. The life of vacuum insulation panels has been continually improving and now easily surpasses the requirements for commercial refrigeration, cryogenic and cold chain applications.

How VIP works

Heat transfer can occur from conduction, convection, or radiation. VIPs consist of an evacuated nanoporous or fibrous core material sealed off with an impermeable enclosure. This results in a thermal conductivity that is lower than conventional insulations. Since the vacuum creates an atmosphere with hardly any molecules, it becomes harder for heat to spread in the space, making heat transfer to surrounding molecules nearly impossible. Without the presence of gas in the vacuum insulation panel, heat transfer by convection currents also cannot occur. Heat loss through radiation is also important to consider, as there is no way to completely prevent heat loss. However, the highly reflective coating of the VIP can prevent a significant loss of heat. Panasonic's Vacuum Insulation Panels have a thermal conductivity value of about 0.0018 W/mK. VIPs can easily range from R-30 to R-60 per inch of thickness and are readily available in the marketplace today.

Why not just use conventional foam insulation?

Standard foam insulation can be as much as 20 times less efficient than Panasonic's VIP. Conventional insulations have a much lower R-value than vacuum insulation panels and bring with them a host of environmental concerns. Urethane foam, for example, contains several harmful chemicals and can be very toxic if exposed in high amounts. Panasonic’s Vacuum Insulation Panels are composed of 75% recycled material, are completely recyclable, have a low Global Warming Potential (GWP), and are RoHS compliant.  Furthermore, they do not off-gas at all, making them an overall greener option for thermal insulation.
