VIP Insulated Fumed Silica Vacuum Insulation Panels Insulation External Walls

There are three modes of heat transfer: conduction, convection, and radiation. By removing most air molecules to create a vacuum, we largely eliminate conduction and convection. Conduction is the flow of heat from molecule to molecule, and convection is the transfer of heat by moving molecules. In a vacuum, there are far fewer air molecules, so conductive heat flow and convection nearly stop.

The high barrier film around the vacuum panel should not be damaged. If the plastic film is punctured and air flows in, the thermal conductivity rises up to 0.020 W/mK. Therefore, it is not possible to cut vacuum panels to the appropriate size on site or puncture them with dowels. However, vacuum panels can be glued to other surfaces or integrated into different constructions with appropriate covers.

In general, thin vacuum panels can be bent into cylindrical forms within some limitations. The thinner the panel, the smaller the possible curvature radii. Regular vacuum panels cannot be formed into complex forms with two-dimensional curvatures like spherical parts. However, new technologies allow us to produce more complex shapes, even panels with holes. Please contact us for details if you have special requirements.

Short term exposures of high humidity don't cause any problems to the used films of the vacuum panels. However, they should not be exposed to high humidity for longer periods of time, especially in combination with high temperatures. Therefore, it is advisable to install humidity barriers in such a way that the vacuum insulation panels are kept dry.
