A window that is damaged should be repaired by an expert to ensure that you get a perfect seal and optimum energy efficiency.
First, you will need to get rid of any broken glass.

When a window seal fails humid air can leak between the two panes glass, creating fog. It's a frequent issue and can cause the window to look visually distorted. When the seal fails the argon or any other inert gas will be removed from the glass, further reducing its insulating properties.
A broken window seal can be repaired by having it replaced with an entirely new one by an experienced glazier. However, this could be expensive and may not resolve the fog problem entirely. Certain companies offer defogging solutions that involve putting an air pump inside the window frame to remove the moisture and leave the glass clear. This method isn't foolproof, and it does not replace inert gasses, which means that the fog may come back.
