How can you avoid thermal stress fractures?

A thermal stress fracture is a glass breakage that appears to occur without cause. There was no impact on your glass, yet a crack has appeared. A thermal fracture is caused by temperature differences in your window pane that create tension in the glass, resulting in a very recognizable break. You will see a fracture line that starts perpendicular to the edge of the window and then fans out into hair-shaped cracks.

A typical cause of a thermal fracture is a roller shutter or a screen that has not been fully lowered or raised. Especially in the summer, the glass is then heated unevenly, which creates tension in the glass, resulting in a thermal fracture.

We would like to provide you with some tips to avoid these annoying and costly fractures:

1. Always raise or lower your screens and roller shutters completely
2. Do not apply posters or dark stickers to the glass
3. Do not place large objects, such as teddy bears or sofas, in front of or against the window
4. Do not place heating elements, such as patio heaters or radiant heaters, near the glass
5. Do not spray warm glass with cold water; and naturally, do not spray cold glass with warm water
