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. To do this, you can glue it with clerical tape or silicone glue, wait for it to solidify, and only then close it. Much depends on the degree of damage to the window unit, so repair will not always be required. 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. In case the crack is large enough, in this case temporary repair may be required.

If you need to close the window, regardless of whether you repaired it or not, you should do it as smoothly as possible and without sudden movements. Any blow to the sash can aggravate the situation, up to the complete destruction of the cracked glass. With the appearance of small mechanical defects, the margin of safety of the glass unit begins to decline significantly. Close the window as smoothly as possible and without sudden movements. 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.
