What Is A Windshield?

Now before we dive into more complex stuff and start discussing the best windshield repair kit, let’s first cover some of the basics and learn what is a windshield. I bet that there are not a lot of people who are into cars and are reading this and need to know what makes a windshield glass quite different from other automotive glass. So, let’s get into it.

One of the most important things to know about windshields is that this type of glass is a safety glass. This means that it is designed in such a way to prevent life-threatening situations on the road.

For most of the windows, cars are using tempered glass. The tempered glass is a special safety glass that shatters into small pieces on impact. This is the glass that you have on the doors as well as the rear window.

But unfortunately, using this glass on the front window is not possible. Because imagine if there is a rock that hits your windshield. You just don’t want the glass to burst and end up in your eyes and face.

So, something else had to be invented for this purpose. And that is the windscreen laminated glass. Laminated glass is a type of glass that holds together when impacted. This means that there could be chips and cracks. But in most cases, the windshield will stay uniform and you will not have to worry that will shatter into pieces.

All this is possible because the glass is held by a thin layer of polymer that is sandwiched between two layers of glass. This polymer layer simply does not allow the glass to shatter into pieces. But what is the best windshield repair kit? More on that in a bit.

Reasons Why Windshields Crack

Now before we learn what is the best windshield repair kit out there, let’s learn more about the reasons why windshields crack in the first place. Knowing this will help you avoid your windshield cracking in the first place.

The first and most common cause of windshield cracking is road debris. Imagine that you drive on the highway with a speed of 70mph and there is a car in front of you that drove over some pebbles and it basically lifted them up in the air.

Then you drive through these pebbles that are floating in the air at 70 mph and your windshield doesn’t stand a chance. It will crack, even if you hit the rock at smaller speeds it could still crack. This is the most common reason for this problem with the cracked windshield.

The second very common cause is bad weather. If you live in a place that has a ton of hale storms. Then you will highly likely end up with a cracked windshield or a cracked rear window. These are simply rocks of ice that could cause a lot of damage.

The next cause that could make the windshield crack is a sudden change in temperature. Imagine that is really cold outside and the windshield is frozen. Then you get the idea to defrost it with warm water. This is a bad idea from the start because you will end up with a cracked windshield. Glass simply does not want abrupt changes in temperature.

And the last type of damage that we are going to cover is the collision damage. If you’ve been involved in a collision, you can expect your car to have a cracked windshield. Glass doesn’t tolerate big impacts. But what is the best windshield repair kit? More on this in a bit.

How To Prevent Windshield Cracking?

Now before we dive int to the types of best windshield repair kit, let’s learn more about how you can prevent cracking development on your windshield.

As you probably know, everything starts with small chipping. That small chip is caused by the impact of pebbles on the road or hale.

Then as you drive the car and go over bumps the crack will start to spread across the whole windshield and you will end up with a spider web of a windshield.

In order to prevent cracking you need to perform an immediate repair on the small chip. And by immediate, I mean you need to do this really fast.

The more you drive the vehicle like this, the worse it will be and your windshield will start to crack and when it does, you will not be able to repair it at all. You will have to replace it. This is why you want to avoid this type of situation. So, you need to learn which is the best windshield repair kit and fix the window. But more on that in a bit.
