This glass can be made safe with the application of clear safety film applied to the glass and then anchored to the frame with a structural silicone. Kumar Where is the location of this blast? How did you measure this 7mm? How far it is from edges? Send me a picture. Give complete details in order to advise.
Send me a picture- a detailed picture to support you. Suddenly a full glass has broke …. He only have minor injured as he touch the shatter surface when he trying to check what is happening. Can you advice what is this cause? Ihave a cupboard door which spontaneously shattered after 4years. All the screws were protected by mushroom shaped plastic covering apart from the one in line with the centre of the radial cracks. Could this be the reason after 4 yrs.
It does not stand in direct sunlight and room temperature constant. I had a double pane window crack on the inside only, however, it looked like it was from the impact of something that would have had to have been from the outside. Is this possible? We ordered triple glass unit with heat strengthened inner lite instead of tempered.
Is there any solution for this? I have a 2mm chip in the inside of my hurricane impact door. You cannot feel it from the inside or the outside as it is in between the glass. The vender says it is too small to worry about.
I feel as if it is compromising the integrity of the door and is still under warranty and should be replaced. Hi Kristin, If the glass in question is tempered glass, then the chip was in the glass before it was tempered.
In which case your supplier is correct in his assessment. If howvere, the glass is plain float laminated and is chipped, then there is a slight inherent weakness at the point of the chip, which could lead to cracking in the future if the glass is stressed. Ourshower door exploded at about am this morning. We were sound asleep and no one wad in the bathroom,thank goodbess. Excellent article ; Very informative, concise and to the point. Bernard Heeney, Jones Engineering group, Ireland.
We have a terrace aluminium sliding door. We went back to our apt. We have a good idea as to how glass was broken, but we have been told that by resting carton on glass, this causes thermal breakages. Please help. I also have photos of breakage in case anyone wants to see. Hi, Yes this is possible. Because it causes glass to heat and cool at different areas, leads to occur thermal stresses.
In solar module manufacturing, sudden breakage of glass inside laminator which point of propagation is at edge could it be because of inclusion or stone?
Pls give me some suggestions. My window has spontaneously shattered on a hot night. Should the manufacturer pay? They say No As it is over 3 years warranty. I have one incident on my handed over project.
Laminated balustrade slope glass has broken and hanged outside. There was no impact mark on glass. Even how come both internal glass has broken.
Any faced similar situation and can guide. Good day Michael L. I am impressed by reading your article, I found it a very informative post about Spontaneous Glass Breakage: Why it happens and what to do about it.
This post is very useful for everyone. Your article is great I loved it and i will love to read more from you, dear. I need to remove some damaged wood for replacement. Will cut using a small circular saw and an oscillating saw.
I like how you have explained the problem and the solution too. I have seen similar information at one place, you can also see on Grandglass. You would get to know about the spontaneous glass breakage and why it happens and what to do about it. I enjoyed reading this article. It makes the work straight and easy for us. However, in certain circumstances the small broken chips can still pose a danger.
For example, a glass balustrade, spandrel or overhead glazing that shatters and falls from its frame could cause significant injury if anyone happened to be unfortunate enough to be standing underneath it.
Even without the issue of safety, replacing toughened glass in inaccessible areas can be a major not to mention expensive inconvenience. This is known as spontaneous glass breakage and is, in actual fact, generally triggered by one of four factors:.
Minor damage during installation such as nicked or chipped edges that later develop into larger breaks. Overly tight binding of the glass in the frame, which causes stresses to develop as the glass expands and contracts due to thermal changes or deflects due to wind.
While factors such as installation damage and incorrect fitting can be avoided to some degree by experienced glass technicians, avoiding glass that contains nickel sulphide is somewhat more difficult.
These inclusions are invisible to the naked eye and are almost impossible to completely avoid in the plate glass manufacturing process. During the tempering process, plate glass is heated up to its softening point, then rapidly cooled.
The "sandwich with some give" that laminated safety glass is made of also helps hold the occupants in a vehicle! Banks use a multiple-layer laminated glass to help stop bullets. Laminated safety glass resists falling out of its frame during an earthquake or a tornado. The tempering process increases the strength of the glass to five to 10 times that of untempered glass. Tempered safety glass breaks differently than regular clear glass. When tempered safety glass is struck it does not break into sharp jagged pieces of shrapnel-like glass as normal window panes or mirrors do.
Instead, it breaks into little pebble-like pieces, without sharp edges. It is used in the side and rear windows of automobiles. Eyewear uses tempered glass that has been tempered using a chemical process. You can easily spot tempered safety glass in an automobile rear windows on a sunny day if you are wearing polarized sunglasses.
