"Spontaneous Breakage Of Glass Is A Common Event"

"The most common cause of spontaneous glass breakage are:

• Internal defects within the glass such as nickel sulfide inclusions
• Minor damage during installation such as nicked or chipped edges later developing into larger breaks normally radiating from point of defect.
• Binding of the glass in the frame, causing stresses to develop as the glass expands and contracts due to thermal changes or deflects due to wind
• Thermal stresses in the glass
• Inadequate glass thickness to resist wind load

The security camera in this home captured the moment when one of the above reasons caused the failure. Solartek Films Ltd Edge Retention and Safety Film will prevent the glass from falling and stop potential injury and damage on people and property below."
