Why do double-glazed windows crack? Common causes of cracks

Thermal stressOne of the most common causes of cracks in double-glazed windows is thermal stress. This occurs when the temperature varies significantly between the interior and exterior of the window, causing disproportionate expansion or contraction of the glass. Windows exposed directly to sunlight, especially south-facing ones, are more prone to this type of problem.

Improper installationIncorrect installation of windows can place pressure on certain areas of the glass, which may lead to cracks over time. Using inadequate materials or neglecting installation standards significantly increases this risk, especially when the glazing is misaligned or one pane bears most of the weight.

Structural frame defectsWindow frames play a crucial role in supporting and protecting double-glazed glass. If the frame is damaged, misaligned, or made from low-quality materials, it can affect glass stability, increasing the risk of cracking.

Mechanical impactDouble-glazed windows can be damaged by blows or direct mechanical impacts from either inside or outside. Children playing near windows or objects thrown accidentally can cause cracks that may expand quickly.

Poor material qualityUsing low-quality double-glazed glass or inappropriate solutions in the manufacturing process can make the glass more vulnerable to cracking. Therefore, it is important to choose trusted brands like Salamander, known for their durability and performance.

Maintenance of the frame and hardwareRegular inspection of the frame and hardware is crucial to prevent cracks caused by structural issues. Maintaining window hardware and periodically adjusting moving parts ensures optimal operation and protects the glass from unnecessary stress.

Protection against mechanical impactEnsure that the window is protected from accidental impacts. For homes with children or pets, consider using curtains or blinds to soften potential impacts.

Apply solar protection solutionsTo prevent thermal stress, use solar protection solutions for windows. These reduce the amount of sunlight entering your home, protecting the glass from extreme temperature fluctuations.
