It is still used in certain applications and is a tight pain as it needs to be gassed then sealed very quickly.
Modern glazed units have silica in the silver spacer bar to remove moisture. Of course if they are not sealed properly then this fails quite fast.
See if you can get replacement glazing fitted as you will get k glass now.
