Air bags, seatbelts, and windshields have a common purpose: enhance your safety. A vehicle’s condition is known by how these parts are maintained by the owners. Out of these three, the windshield is the most important because of its additional features and benefits. It is apparent in how it keeps up the structural integrity of the vehicle when dealing with the heat often seen during the summer in North Scottsdale.
In this article, we will see how worthy are the windshield repair and other auto glass replacement services. The components of a windshield might give some clue to how it is repaired. Two sheets of glass are laminated using a layer of polyvinyl butyrate (PVB) to make a piece. A chip or a crack is the most common problem and it tends to spread over a period. An early repair can save a lot of time and money. The manufacturers’ specification of installing a windshield is nearly impossible to duplicate as well. Therefore, in many cases, replacement is not advisable.
North Scottsdale Windshield Replacement – Cost Factors
We don't spend much time in our lives thinking about one of the most ubiquitous products surrounding us every day: Glass. Glass is everywhere! Look around and you will see it in your home, office, eyeglasses (unless they're plastic), ceramics like toilets and dishes, bottles, light bulbs, tv screens, and of course in your car.
What is Glass? It's a combination of materials, most commonly silicon dioxide (sand), lime, and potash. There are specialty glasses made of other materials but the kind we see all the time, soda-lime glass, is mostly composed of the three materials mentioned above. For an easy-to-understand detailed explanation of glass, visit Wikipedia and type in the search term glass.
The two common types of glass we interact with daily, annealed and tempered, are basically the same products that have undergone different manufacturing treatments to give them individual characteristics. These characteristics are designed to serve certain functions.
Tempered glass is known as safety glass because it shatters into hundreds of tiny blocks, instead of into long sharp-edged, knife-like shards that can inflict terrible wounds. The small blocks of broken tempered glass are much less likely to cut human flesh. Tempered glass is used in the side windows and back glass on cars, as well as in commercial glass, sliding doors, and windows that reach to the floor.
Annealed glass, like in your kitchen window, is used to make windshields. You might wonder how in the world a kitchen window can be used in front of a driver. That's crazy! Yes, that would be crazy, unless the annealed glass was laminated together with a strong piece of plastic and another piece of glass to make a sandwich called laminated safety glass.
When you look through your windshield, you are looking through all three pieces, two of glass and one of plastic. The glass sticks to the plastic when it breaks. No doubt you've seen a shattered windshield and noticed that it hangs together in one big cracked piece. This is what makes the windshield different from your kitchen window.
Tempered glass is very tough and is difficult to break unless it gets punched with a sharp object. You may have seen a tool advertised on TV that's used to escape from a car by breaking the tempered side window. The tool is like a small hammer with a sharp point. Sadly, criminals have also discovered a use for it and keep it in their criminal toolbox. If you've ever suffered a broken window during a car break-in, it was probably done with one of these tools.
When it's manufactured, tempered glass is just like annealed glass. Then it goes through a heating process to "temper" it, making it tough and resilient. The glass is cooled quickly so the outside contracts and forms a compressed outer layer. It puts the whole piece of glass under tremendous stress and that's why it seems to explode when broken. The stress is released so powerfully that the glass breaks into harmless little chunks.
Why isn't tempered glass used in windshields? Many years ago it was used for windshields in some cars. Laminated safety glass just makes a better, safer product for the front of your car because it stays in place, even when broken, and keeps flying debris out of your face. It also helps to keep occupants inside the car.
The glass that we know is an unusual and interesting substance. Other materials can also be classed as glass. You might say that glass is not a substance but a quality or characteristic. A scientist might refer to glass as a state, much like a gas, liquid, or solid. Water makes a good example. Water can be gaseous (steam), liquid, or solid (ice), however it is not seen in a glassy state like liquid rock (lava) or molten metal.
Nature produces glass constantly. People who live in volcanic areas are familiar with obsidian, a glass used by early Americans to shape arrowheads, spear tips, and knives.
Just remember that when you are replacing your auto glass, the material you are looking through has an interesting history and unique characteristics that few other materials can match. Glass has been around for centuries and will endure into the foreseeable future.
Windshield Repair and Replacement - 5 Tips For Your Family's Safety
Today's automotive windshields are not simple composed of glass as the name might suggest. Modern windshields are made from laminated safety glass that include two layers of glass sandwiched around a layer of PVB (polyvinyl butyrate). This is for safety reasons. During a crash or other occasion when the windshield is damaged, sharp pieces of glass will tend to stick to the PVB layer. This decreases the potential danger from flying glass, to passengers in the cabin of the vehicle. The PVB layer in laminated glass also serves to protect passengers and keep them inside the vehicle during collisions by exerting a cushioning effect.
Heat strengthened, alson known as tempered, glass is considered to be a form of safety glass as well. This type of glass is commonly used in vehicle side and back windows as opposed to windshields. Tempered glass crumbles into rounded glass pebbles which are relatively harmless, when broken.
Tempered glass cannot be repaired, but laminated safety glass can. This is why it is very common to see windshield repair services, but nobody typically offers to repair side or rear windows in the same fashion.
Modern windshields are no longer simple panes of properly-fitting glass. They are now complex, engineered glass systems with such elements as: heating mechanisms to melt ice; coatings to repel harmful ultra-violet radiation from the sun; shade bands to help the driver fight glare; high performance radio and telephone antennas; satellite uplinks; heads-up holographic instrument displays; and sensors to activate windshield wipers or close convertible tops. Because of dramatically increased performance expectations, the cost of the modern windshield has increased quite a bit as a result.
With windshields costing more than ever, it only makes sense to repair them, in incidences of damage, rather than replace them. There are many companies offering such a service, but NOVUS windshield repair [http://lasertargeted.com/glassrepair/windshield-repair.html] is one worth investigating further. NOVUS is the dominant automotive franchisor in the United States, and NOVUS actually invented windshield repair, back in 1972 (and has repaired over 20 million windshields since then), and started franchising windshield repair in 1985. NOVUS has also made windshield and auto glass replacement [http://lasertargeted.com/glassrepair/auto-glass-repair-replacement.html] service available since 1995.
Windshield repair is achieved by injecting a specially formulated resin into the damaged area. The resin is cured and polished, restoring structural strength and clarity to the auto glass. Most insurance companies will waive the deductible and pay the whole cost of a NOVUS repair. NOVUS can repair about 70% of the windshields it inspects. A general rule is if the damaged surface area on your windshield can be covered by a credit card, the odds are very good that it can be repaired. If you want more clarification or confirmation of this, call 1-800-77-NOVUS and your windshield will be examined by a skilled NOVUS technician at no charge to you. Once your windshield is repaired, the damage should be barely noticeable (no bigger than a sharp pencil point mark).
NOVUS guarantees their work. They guarantee that a NOVUS windshield repair will restore strength and clarity to the glass; will stop the spread of further damage, and will pass vehicle inspection in all states for as long as the customer owns their vehicle, or NOVUS will refund the cost of the repair. NOVUS repairs are also environmentally friendly and will extend the useful life of the glass, and will save you money over windshield replacement.
