What is thermal shock?

• Direct sunlight: When sunlight directly strikes one part of the glass, it can overheat compared with shaded areas.
• Uneven heating: If part of a window or facade remains shaded while another is exposed to sunlight, glass layers expand unevenly.
• Indoor heating or cooling: Radiators, air conditioners and other heat sources near glass can create temperature differences between inner and outer surfaces.
• Dirt or stickers on glass: Materials such as dirt or stickers can prevent uniform heating and create additional stress.

• Choosing more resistant glass: Toughened or strengthened glass is more resistant to temperature changes and recommended for windows exposed to direct sunlight.
• Correct installation: Professional installation ensures even load distribution and minimises potential stress in the glass.
• Protection from sunlight: Installing awnings, blinds or reflective films on the glass can reduce direct solar radiation.
• Regular maintenance and cleaning: Clean glass allows uniform heat distribution, reducing the risk of stress.

Preventing thermal shock is crucial for insulating glass longevity and safety. Appropriate materials, correct installation and additional protection can significantly reduce damage risk and extend the life of glazed surfaces.
