Question: 1 / 400

Which of the following can lead to glass breakage post-installation?

Poor maintenance and cleaning practices

Direct sunlight and exposure to humidity

Poor support, thermal stress, and impact

The factors leading to glass breakage post-installation include poor support, thermal stress, and impact. Proper stabilization is crucial in ensuring that glass panels are protected from undue pressure or shift. If glass is not adequately supported, it can crack or shatter under its own weight or due to external forces.

Thermal stress occurs when there is a significant temperature difference across the glass surface, which can happen if one side of the glass is heated by sunlight while the other remains cool. This difference in heat can cause the glass to expand unevenly, leading to breakage.

Impact refers to any forceful contact that can result in physical damage to the glass. Even minor impacts can compromise the structural integrity of the glass, making it vulnerable to breaking. Understanding these factors is essential for ensuring the longevity and safety of installed glass products.
