Chevrolet Express 3500 Auto Glass
When driving around your Chevrolet Express 3500 in everyday life, reliable auto glass is needed to give you adequate protection. The risk to you from potential hazards on the road can be significantly reduced with this valuable safety feature for your car. If your Chevrolet vans glass is in need of attention, here is some valuable information.What are the different kinds of auto glass?
The Chevrolet Express 3500 model uses safety glass as opposed to the kind of glass you find in house windows or the mug in your cupboard. The main difference between auto glass and other types is the need to take two main factors into account. The first is from any form of impact, whether it is from another vehicle or foreign object, and the second is from the stress vehicle windows will endure from everyday driving. The two goals in developing adequate safety glass for your Chevrolet van are to protect passengers from injury and to maintain the structure of the vehicle. There are two specific forms of safety glass used in your vehicle to address these concerns.
- The windshield of your Chevrolet Express 3500 is made from a tripartite structure called laminated glass. It is made by taking two sheets of glass and compressing a sheet of polyvinyl butyral (PVB) between them. Through a process involving heat and pressure the three sheets are fused together creating a structure that is highly resistant to impact. The adhesive nature of PVB spreads out the force of impact creating the telltale spider web cracks you see in windshields involved in an accident. It is due to this bond that shards of glass do not fly around after impact. The PVB also reflects 95% of the suns UV rays giving an added layer of protection.
- The side and rear windows in the Chevrolet Express 3500 are made from a different process to give them the strength to resist the natural shifting around a vehicle does when in motion. Taking heated glass and cooling it quickly makes tempered glass which is several times stronger than normal glass. This is because the cooling process causes the outer layers of glass to cool quicker than the interior. This stress resulting from the temperature change increases the strength of the window, allowing it to easily handle the stress of normal driving.
Damage generally comes in two forms, chips and cracks. A general rule of thumb is that if the chip is larger than a quarter or a crack is longer than 3 inches, then you should have the vans window replaced.
