Bullet Proof Glass: How It Works

Always wondered how bullet proof glass works? Here are some helpful questions to answer your long-standing curiosity about one of the most enduring safety features in many workplaces around the world.

What’s bullet proof glass? Know what it is but not exactly sure how it works? More accurately termed as bullet resistant glass, it refers to glass that’s made up of polycabornate, which is a type of plastic that’s known for its strength and sturdiness. That polycarbonate is then put in between layers of tough plastic.

What does it do? Bullet resistant glass is wholly capable of stopping high-velocity projectiles—in this case, bullets—in their tracks. According to HowStuffWorks, that’s because bullet resistant glass is designed to slow down the projectiles. The slower the bullets, the lesser the impact and resulting damage in any situation.

How does this happen? When a bullet comes in explosive contact with a bullet resistant glass, it hits the first layer of tough glass. The plastic is able to effectively slow down the bullet that when it hits the polycarbonate layer, it doesn’t have as much velocity and strength to pass through because the impact has already been absorbed by the layers of plastic.

How effective is it? To know how effective a particular bullet proof product is, one must take into consideration the thickness of the material. That said, the thicker the glass you have, the slower the bullet which reduces the force behind it. However, a glass that’s too thick will have several problems, mainly because of the added heft. The added layers too would eventually result in glass that might be too dark. That could be a little problematic, especially since most bullet proof glass are transparent to allow for sight and easy access.

When do you use bullet resistant glass? Plenty of industries, especially work environments that emphasize the need to take all manner of safety precautions, encourage the installation and use of bullet proof glass. From government offices to banks, from military bases to convenience stories, bullet resistant glass is a standard in many facilities and establishments. But that’s not the only use for this protective material as bullet proof windows and doors along with glass and panels have all been a permanent fixture in many workplaces.

So if you’re looking for a way to improve your security and protection, you might want to give bullet proof glass a try.
