Vacuum insulation panels are usually made from a core made of microporous materials and a gas-tight envelope, which, depending on the application, can be a metal composite film, a plastic or a stainless steel sheet.
The air is pumped out of the plates in a vacuum chamber and then sealed gas-tight.
The insulation core usually consists of microporous silica or PS or PUR rigid foam. Getters (gas-absorbing substances) are added to improve the long-term stability of the vacuum.
