Take a look at the frame of the broken window to determine the size of the new pane. It should be slightly larger than the opening to allow for expansion and contracting and also to account for any imperfections on the frame or on the glass. After cutting the glass, apply glaziers’ compound around the edges of the frame and glass. Once the compound dries then paint it over it to match the rest of the window frame.
Condensation on the Inside of Double Glazed Windows
The appearance of condensation on the interior of double glazed windows usually indicates that a seal has broken somewhere in the window unit. This is a major issue, as it can indicate that heat is being lost from your home through the window.
Double glazing is designed to block heat transfer between two panes, by sandwiching an air or vacuum layer between them. This creates a tight seal that prevents warm air from escaping. If the glass is colder than the frame, condensation could develop on the glass and cause damage to the window. If you are unable to solve condensation issues on windows with double glazing by opening windows or using extractors, dehumidifiers or trickle venting, you may need an expert.
It’s rare for condensation to form on the outside of double glazed windows but it can happen in the event that the seal between the glass and window frame has begun to weaken. This is more prevalent in winter, when the temperature is lower, making it more likely for condensation to form. The primary reason for this is a defect in the spacer that is used between the frame and the window. This spacer contains desiccant, which is highly absorbent and will absorb any moisture that is present.
This can lead to moisture seeping through the gap once the desiccant is saturated. This can cause condensation and water to build in the gap which is difficult to remove.
The positive side is that many trustworthy window manufacturers will provide an assurance on their products. They should replace the window unit and glass when it’s damaged by condensation. It is essential to report any issues to your window installer immediately you notice them so that condensation can be fixed promptly to prevent further damage to the window unit as well as the frame around it.

Once the frame is cleaned and the rabbet is prepared, it’s the time to prepare for the replacement of the broken pane. Purchase a piece of double strength glass that is 1/8 inch smaller in both directions. You’ll need glass points which is a steel triangle that holds the glass in place.
