Breaking laminated glass (such as car windshields or safety glass) requires certain skills and tools, as it is originally designed to resist impact and prevent shattering. The following are the specific methods:
1. Use dedicated tools (recommended method)
Window breaker (escape hammer)
Designed specifically for laminated glass, the tip is made of high-hardness alloy, capable of concentrating pressure to shatter the glass.
Steps: Aim at the corners of the glass (the edges are the most fragile), press or hammer hard. The glass will crack into a net-like pattern, and then use tools to clean up the fragments.
Spring-type window breaker: After pressing the button, the spring-driven impact pin instantly shatters the glass.
2. Emergency alternative tools
Sharp and hard objects (such as keys, screwdrivers, axes) :
Repeatedly tap the corners, but the efficiency is relatively low and continuous force is required.
Metal rod/hammer
Strike the edge hard. You may need to try several times.
Firearms (in extreme cases) :
The bullet may penetrate but won't completely shatter the glass (the adhesive layer will block it).
3. Special methods for car windshields
Remove the windshield wipers and pry the edges with a metal rod
The edge of the windshield is fixed with glue. Prying the edge may cause it to loosen.
Cutting the adhesive layer
Cut the sealant around the glass with a knife and remove it as a whole (which takes a relatively long time).
4. Precautions
Prioritize attacking the edges or corners: These areas have lower strength.
Protective measures: Wear gloves to avoid cuts and cover your face to prevent debris from splashing.
Laminated glass characteristics: Even if it breaks, it will not completely disintegrate and needs to be removed manually.
Avoid ineffective methods: Ordinary hitting of the central area may only produce cracks.
5. Emergency situations (such as escaping from a vehicle)
If the tool fails, you can try kicking the edge of the side window hard with your foot (side Windows are mostly tempered glass, which is more fragile than laminated glass).
