How to seal a cracked window?
If a double pane window was mechanically damaged, then before replacing it, every effort should be made to restore the window tightness or at least to prevent the complete destruction of the glass.

If the crack on the glass is relatively small, does not cause inconvenience for its presence, except for the limitations in the operation of the window, then you can just wait until the craftsmen do the repair work.

As soon as you manage to do this, try once again to prevent it from opening and any intensive use. Remember that any careless movement resulting in a blow to the cracked glass will contribute to its further destruction. Only with careful handling will it be possible to have confidence that the glass will last until the glass unit is replaced.
