What Causes Glass Windows to Crack

You may have recently noticed that you have a crack in the window.

What was once a small, unnoticeable crack at the edge of your window has now made its way up to the middle. And now, you regret letting that little crack go unnoticed because you have to replace your windows.

Cracks in glass windows are fairly normal, and there are many reasons why they occur. Here are a few.

Stress Cracks

Thermal stress cracks, also known as stress cracks, are cracks that occur in glass windows due to an increase in temperature. When faced with higher temperatures, different parts of glass windows expand at different rates. Stress cracks are a result of uneven expansion due to pressure.

Typically starting near the edge of the window and spreading out over the glass, stress cracks can occur due to the temperature inside and outside your home.

Pressure Crack

A little less common than most, pressure cracks are often found in insulated or double-paned glass windows. Pressure cracks are in a pattern similar to the curve of hourglasses and usually occur due to improper installation. If you install your insulated window too high or too low, or if there are any extreme pressure system changes in the weather, these cracks can show up on your window, requiring complete replacement.

Impact Crack

An impact crack occurs due to your window coming into harsh contact with something else, for example, a ball. Easily identifiable due to their starburst pattern that emanates from the center of the crack, these cracks can be dangerous. Remember to clean up any glass that’s fallen inside or outside your home, and keep children and pets away.

How to Fix Broken Windows

To repair gaps and cracks in your windows, you can use a caulking gun to fill the spaces or cover the crack with duct tape. However, these are just temporary measures.
