ABSTRACT:
Fogging and discoloration of multi-pane windows is prevented by sealing the windows with a polymeric seal and by sorbing off-gases evolved by the seal through the use of diatomaceous earth. The diatomaceous earth can be disposed within the volume defined by the panes and the seal, preferably by being disposed within a hollow spacer, or the diatomaceous earth can be mixed with the seal itself. If the diatomaceous earth is mixed with the seal, it can constitute about 1-15 percent by volume of the seal, preferably 1-2 percent by volume. Diatomaceous earth has been found to be especially effective in preventing fogging and discoloration of low emissivity glass.
