During the process of polymerization, the risk of blowing up the whole equipment is always there. This is one of the foremost reasons that professionals never make plexiglass car windows. Installing a plexiglass car window might cost less but still, the drawbacks are at hand.
It states that plexiglass sheets start to melt at degrees C. You might have to park your car away from the high temperatures or flames. The direct contact of plexiglass windshield with flames might call some trouble and cost you to fortune.
This particular glass type cannot bear up extreme temperatures. This makes it unfit for the car windows. The plexiglass car windows might have durability and flexibility features. But, these are extremely prone to scratches. The acrylic-based glass gets scratches with everyday use. One may have to install a thick transparent film on both sides of the glass to make it secure.
Taking maintenance tips from professionals will assist greatly. One can never recycle the plexiglass and use it for further use. The toxic and chemicals make it unfit for recycling purposes as well. Cutting large pieces into smaller ones for reuse is an option.

The link you posted was particularly helpful. Another point to consider. Emergency responders are trained to extract motor incident victims through the quickest means possible. When the door is jammed, that often means the breaking the window.
Aron Plexiglass is not an issue for rescue teams, it can be cut rather easily with appropriate tools. It will be an issue for the driver who needs to escape his car which is burning or drowning, though - the driver is likely to have very few tools at his disposal, a car window breaker at best. Also, Plexiglas is very common for light aircraft. The reason is weight. However, this comes at a downside. It will scratch much more easily than tempered auto glass.
It is not uncommon to see an older aircraft window that is full of small scratches, making poorer visibility. Aron That's not true. Extrication through a window is generally the last choice. Second, taking injured patients out through windows is extremely difficult and awkward. It's never a first choice. In fact, I've never seen it done in 15 years of experience working car crashes.

Would it not be possible to create a combo windshield, thin sheet of plexiglass at the top of glass or the opposite. Would that not get rid of the shattering issue and retain elasticity?
Yes but the headlights are plastic not acrylic. Plexiglass is acrylic and does not become yellowish as time goes by At least not as fast as plastic.
As i said i had it for about two years and there is no hint of loss in transparency. The only issue is with scratches. I think the issue is as you mentioned with collision reaction, where the glass HAS to break instead of having people smash their heads on it PaulB, what's your definition of "plastic?
AnthonyX I'm not convinced that planes have exactly the same safety considerations and weight is a much bigger factor, there. Assuming you're in a country with a population of more than a few million, multiple people die in car crashes in your country every single day of the year and everybody says, "Well Duh! It was a car crash. What did you expect? Show 10 more comments. TechZen TechZen 1 1 silver badge 3 3 bronze badges. I've gotten sunburns in cars even with the windows up.
Another thing to mention is that plastics can be easily made to filter out UV if it's a serious issue. JAB That's because you were driving a convertible with the roof down.
When that happens, it initially looks a lot like the early stages of sunburn but it's not sunburn. And glass doesn't degrade in UV light. Not one bit. Interesting take on the tooling front. Thanks for sharing your experience. Taken from wiki information about the car available here All windows — and for the first time ever, the windscreen — are made from polycarbonate to cut weight Local legislation may prevent the use of plexiglass for road car windows, which is reflected in the same article which states The American version Steve Matthews Steve Matthews Polycarbonate and plexiglass are not identical.
Polycarbonat is the tougher of the two, and thus better suited for impact protection and less prone to crack. Add the Renault Megane R26R to your list, some of it's windows are polycarbonate too. Can you elaborate on this? It's a good start to an answer, but more detail would improve it - for example, why is scratching bad? What causes it to scratch? I voted to keep this for now to give the poster a chance to elaborate. Surely glass is fairly fragile and can not only be scratched but cracked, shattered and holed and that's suitable for road use.
SteveMatthews, glass has a Mohs hardness of around 5. Most plastics don't even register on the Mohs hardness scale. SteveMatthews Glass is fragile in that when it fails, it fails thoroughly, but this requires an impact of significant force, especially with tempered glass. Unless that happens though, it's virtually immune to regular wear. Plastics, however, can be scratched by common dirt, and etched with household chemicals - as people who clean plastic-lensed glasses with their shirt or windex learn.
Acrylic sheeting can be cut much like wood, using similar tools such as a router, scoring tool, or table saw. Additionally, plexiglass sheet weighs roughly half of what glass does, making it much easier to move, cut, and install. Because it can be easily cut and is fairly light-weight in comparison to traditional glass, acrylic sheeting is ideal for use when making an accent window, or designed window.
Glass is not practical when designing windows for architectural pieces and it is too brittle and rigid, the flexible polymers in plexiglass allow for custom shapes and designs.
Additionally, acrylic sheeting comes in a variety of styles including colored acrylic sheet, fluorescent acrylic sheet, and black and white acrylic sheet. One of the best reasons to purchase acrylic plastic sheets over traditional glass is to remove glare and reflections. Glass reflects more light and the thicker glass is, the more discoloring you will notice. However, no matter the thickness of plexiglass, it always remains clear. Once you take a look at all of the benefits acrylic sheeting has over traditional glass for window applications, it makes sense that manufacturers have been choosing plexiglass for years.
A popular choice for point-of-purchase displays, casinos, toys, and more, our Acrylic Mirror sheeting boasts extreme durability and is available in textured, clear, and colored variations.
