Bullseye Crack: The Classic Impact Mark

Bullseye cracks, resembling their namesake target, are circular fractures caused by forceful impact. Be it a stray ball or an accidental collision, the impact creates a radial burst of cracks from the point of contact. Thermal stress, such as extreme temperature changes, can also induce bullseye cracks.

Chip Crack: Impact from Sharp Objects

Sharp objects, like tiny projectiles, can leave behind chip cracks. These jagged fractures typically extend outward from the point of impact, resembling shattered glass. Thermal stress can also contribute to chip cracks.

Crack-Off: Severe Impact or Installation Errors

Crack-offs are alarming, often extending across the entire windowpane. They are caused by intense impact that shatters the glass, or by improper installation, such as excessive stress on the frame.

Combination Crack: A Hybrid of Force

As the name suggests, combination cracks are a fusion of bullseye and chip cracks. A sharp object may initially cause a bullseye fracture, which then branches outward into jagged lines.

Edge Crack: Stress from Impact or Installation

Edge cracks, as their name implies, run along the edge of the windowpane. They can be caused by sharp objects, thermal stress, or weak edges due to improper installation.

Radial Crack: Blunt Force and Thermal Stress

Radial cracks, radiating outward from a central point, are caused by blunt force. Thermal stress, such as extreme temperature variations, can also induce radial cracks.

Stress Crack: Invisible Forces at Work

Stress cracks are unique in that they appear without any apparent impact. Thermal stress, improper installation, or foreign objects trapped between the glass and frame can create these fine lines of fracture.

Understanding the types of window cracks and their causes is essential for making informed decisions about repair or replacement. Whether you need a quick fix for a small chip crack or a comprehensive solution for a crack-off, knowing what you’re dealing with empowers you to find the most effective solution. Remember, if the crack is severe or compromises the integrity of the window, seek professional assistance for a safe and lasting fix.
