Foggy or cloudy windows are often a sign that the seal between the glass panes has failed. When this happens, moisture becomes trapped between the panes and creates a milky or hazy appearance that cannot be cleaned from either side of the glass.
At Top Cat Services – Glass Division, we inspect fogged windows to determine whether the glass can be repaired or if the insulated glass unit needs to be replaced. In many cases, the window frame can remain in place and only the glass needs to be replaced.
This approach restores clarity and improves the performance of your windows without the cost of replacing the entire window.
Most modern windows use insulated glass units, often called IGUs. These windows are built with two or more panes of glass separated by a sealed air space. The sealed space helps improve insulation and regulate temperature inside the home.
Over time, the seal around the glass can fail due to age, weather exposure, or temperature changes. When this seal breaks, moisture enters the space between the panes and causes the foggy appearance.
Once the seal has failed, the glass usually needs to be replaced to restore the window’s clarity and insulation.
Insulated glass helps reduce the amount of heat transferred through your windows. During colder months it helps keep warm air inside the home, and during warmer months it helps reduce heat entering from outside.
When window seals fail, that insulation benefit is reduced. Replacing the insulated glass unit restores the window’s energy efficiency and helps maintain a more consistent indoor temperature.
Improving window insulation can also help reduce the workload on heating and cooling systems, which may lower energy costs over time.
Our technicians assess the condition of the window and determine the best solution. In many cases the existing frame can remain in place and only the insulated glass unit needs to be replaced.
This allows homeowners to restore their windows without the cost of installing entirely new window frames.
If you are dealing with cloudy or fogged windows, Top Cat Services – Glass Division can help restore clear glass and improve the efficiency of your home.
