Getter system for vacuum insulation panel

A method for producing an evacuated insulation compartment comprising:

• filling said compartment with a microporous insulation material;
• obtaining a first getter material, which is capable of gettering at least a first gas or vapor and a second, different gas or vapor;
• obtaining a second getter material, which is capable of gettering said first, but not said second, gas or vapor;
• placing said first and second getter materials into a package and placing said package, within said compartment such that said second getter material will be more readily exposed to said first gas or vapor than said first getter material, wherein said first getter material will be protected from said first gas or vapor;
• evacuating said compartment to a predetermined pressure level;
• and
• sealing said compartment with said getter materials remaining therein to further remove at least said first and second gases or vapors which remain in said compartment or which permeate into said compartment.
