Double glazing is made up of two panes of glass with a layer of gas in between them, making it extremely strong and difficult to break. The gas acts as a shock absorber, making it even harder to shatter the window.
However, it is still possible to break double glazing with enough force. A sharp tap with a sharp, hard object near a corner of the window can cause the toughened glass to shatter into tiny pieces. This can be done by using a tool like a hammer or even a brick.
Modern double glazing is designed to withstand a lot of force, so throwing a stone or a brick at the window is unlikely to break it. The glass can withstand the impact, and it would take a loud noise to actually smash the window, which would draw attention to the burglar’s activities.
When it comes to breaking a double glazed window, it is important to note that if you throw something at it, you are most likely to break only the first pane of glass. The second pane will remain intact. Additionally, hitting the window in the middle won’t work because the gas between the panes acts as a shock absorber.
The force required to break tempered glass, which is often used in double glazing, ranges from 20,000 to 24,000 pounds per square inch (PSI). This shows how strong and resistant double glazing is to breaking.
In terms of signs that double glazing has blown or failed, one of the most apparent indications is that the windows become cloudy, foggy, or hazy between the glass panes. This is caused by moisture entering the space between the panes. Another sign is water seeping through the window frame, which indicates a problem with the sealing.
While double glazing is difficult to break, small stones can still cause damage. When mowing the lawn, small stones can get caught under the blades of the mower and be sent flying towards the windows at high speeds. These small stones can crack the glass or even cause it to shatter completely.
Overall, double glazing is designed to be burglar-proof and difficult to break. It provides an extra layer of security by acting as a barrier between you and potential thieves. However, it is not completely indestructible and can be damaged by sufficient force or small objects like stones.
What can break a double glazed window
There is a relatively easy way to break double-glazed windows: a sharp tap with a sharp, hard object, preferably near a corner. In the case of toughened glass, the pane will shatter into thousands of tiny pieces.

Can a rock break a double pane window
First, there are the two panes of glass. If you throw something (a brick or a stone, for example) at a double glazed window, it's very likely you break only the first pane and the second one remains intact. Second, the gas between the panes works as shock absorber. So hitting it in the middle won't work.

Depending on the manufacturer, the force required to break tempered glass ranges from 20,000 to 24,000 PSI (or pounds per square inch).
How easy is it to break double glazed glass
Double glazing is virtually burglar-proof as it's incredibly hard to break, effectively putting two barriers between you and potential thieves. Furthermore, the gas in-between the gaps also acts as a shock absorber.
How do you tell if a double glazed window is blown
The most apparent indication that your double glazing has blown is that between the glass panes, your windows become cloudy, foggy or hazy. Early signs of blown double glazing may also be observed, such as water seeping through the window frame, which is yet another symptom that your double glazing is failing.

While cutting the grass, small stones that are not easily visible can get caught under the blades of your mower and sent flying towards your windows at very high speeds. If these small stones hit glass window panes, they can crack and at worst, cause windows to shatter completely.

What happens when a stone hits a window
As the stone remains in contact with the glass for a large time, the change in momentum of the glass is also large. The change in the momentum of the glass window causes a force to act on it and bend it. The glass bends upto a certain limit and then breaks into pieces due to large change in momentum in it.
Can a stone break a window
When the stone gets really close to the window the electric field of the electrons in the stone's atoms will push against the electrons in the glass's atoms. That force will break the window, and there are no gaps in the field for it to slip through.

Are double glazed windows strong
Double-glazing of windows improves both safety and security. They are harder to break than normal windows. That means they are safer if you have small children and also makes break-and-entering a whole lot harder.
Why did my window randomly shattered
Changes in temperature cause glass to expand and contract, and when this is done at different severities across the glass with the edges and centres changing in opposite directions, the pane is put under stress which can cause it to break.
Why would a double pane window shatter
Because the space between the panes in double glazed windows is often pressurized, exposure to excess heat or cold can cause breakage, particularly with extreme temperature differences on either side of the window.
Is it worth replacing 20 year old double glazing
In short, yes, it is worth replacing your old double glazing. Outdated double glazing could be costing you money and could make a home colder in the winter months. If you have old double glazing, you could make your property warmer by fitting new, higher performance windows.

polycarbonate panels
If you're interested in unbreakable glass that truly lives up to its name, polycarbonate panels are the type you want. Polycarbonate panels are significantly more difficult to break than both standard glass windows and laminated glass mentioned above.
