Can double pane windows break due to heat?

Yes, double pane Windows can break due to heat, particularly from extreme temperature fluctuations or intense direct sunlight. Thermal stress can cause the glass to expand unevenly, leading to cracking or shattering. Additionally, if there are existing weaknesses or flaws in the glass, high temperatures can exacerbate these issues, increasing the risk of breakage. Proper installation and the use of tempered glass can help mitigate this risk.
