The vacuum insulation panel (VIP) is a technologically advanced product that combines high R-value in a relatively thin panel. The vacuum insulated panel consists of a special core panel enclosed in an air-tight envelope, to which a vacuum is applied. This product provides an insulative value of 5-8 times that of equivalent thickness of other insulation materials, such as rigid foam boards, foam beads, or fiber blankets. Panels can be fabricated in virtually any size, making them ideal for inclusion within other building products.

The core of the vacuum insulated panel is an open-cell material that allows a vacuum to be pulled on the assembly. There are several types of cores that are currently being used in vacuum insulated panels: polystyrene, polyurethane, and a combination of silica, titania and carbon. The core is wrapped in a metallic or mylar foil, and the vacuum applied. The metallic film is sealed to maintain the vacuum for a long period of time. Seals are very important, as they represent the weak point of the envelope assembly. There may be some loss of insulative value as the panel ages, depending on the design of the installation. Desiccants are included in the panels to remove any moisture that may occur in the panel. Special materials known as "getters" are used in the panels (except the panels with silica as the core matrials) to absorb gases that may infiltrate the panels.

By far, fumed silica is considered the best material currently available as it exhibits low conductivity up to a pressure of more than 50 mbar and a conductivity at ambient pressure of half that of a conventional insulation material.

Siltherm Microporous Insulation Panel is designed to provide optimum insulation in many high temperature(up to 1000 ℃) applications, Microporous insulation offers an extremely low thermal conductivity, close to the lowest theoretically. Microporous materials are the preferred choice when a large temperature reduction is required within a limited space, or when strict heat loss or surface temperature requirements are specified.
