Why are semi-permeable seals used in the assembly of thermal glass units?

Part 1: If hermetic seals were used, which are completely air-tight, the glass could blow out when the sun beats on the window on a hot summer day and heats the air or gas between the panes. When heated up, gas and air expand thus greatly increasing the pressure between the panes.
