There can be several causes or reasons for spontaneous breakages in tempered glass like impact load poor glazing glass to glass contact glass to metal contact very hard setting blocks etc.
Spontaneous glass breakage shower door.
One minute the shower door was completely intact.
Despite that material s high levels of strength and capacity to meet safety glazing requirements it is uniquely vulnerable to these types of failures.
Don t slam the door.
Homeowners who have experienced this have described the sound as deafening.
Ironically the center tension zone engineered into tempered glass through the quenching process is also what makes it so vulnerable to catastrophic breakage.
