Windshield Repair: What Everyone Needs To Know

Your vehicle’s windshield is composed of three layers: two pieces of glass separated by a thin layer of “PVB” (polyvinyl butyrate). PVB is the plastic film that essentially holds it all together. Depending on the density of the outer-layer and the force of a rock impact, the glass can flex and break. Unless the windshield is completely shattered, most often the damage is in the form of a rock chip. These are generally in the shape of a star, bullseye, or tiny crack. Although it may appear innocuous, over time, a rock chip will more likely than not spread to form a crack. Studies have shown that over 90% of rock chips continue to grow. Fatigue stress due to temperature changes and road conditions work to accelerate this process.You may want to check out Windshield Repair for more.

The first company to introduce a rudimentary system for windshield repair was 3m, with a product called “Scotch Weld.” This system produced an ultrasound vibration to clean the break while injecting an adhesive. It was relatively effective; however it failed to repair many types of damage.

In 1972, Dr. Frank Werner invented a device that could substitute the air within a rock chip with a resin that could prevent a crack from developing. Over time, the science behind windshield repair evolved. Today, windshield repair is considered a favored alternative to windshield replacement in many circumstances. And although the science has evolved, the objective remains the same: to completely substitute the air within the break with an acrylic resin that will improve optical clarity, prevent further damage, and restore the structural integrity of the windshield.

THE WINDSHIELD CONUNDRUM: REPAIR OR REPLACE?
Windshield repair is essentially preventative maintenance. However, most motorists whose windshields suffer rock damage pay little or no mind to it. This is especially true where the damage is outside of the acute area of the windshield – not directly in front of the driver’s view. Hence the saying: “out of sight, out of mind.”

Once the rock chip spreads to become a large crack, windshield repair is no longer a viable option. Unfortunately, the cost of a new windshield can range anywhere between $300 to well over $1000, depending on the vehicle and the type of replacement windshield. OEM windshields, those made by the original manufacturer, are significantly more expensive than their aftermarket counterparts. In addition, many modern windshields offer features such as heating elements, sun coatings, and antennae, which significantly inflate the cost. Even with insurance, the deductible can be so high that it would be pointless to file an insurance claim. Thus, it is easy to understand why a $50 windshield repair is a favored alternative.

But cost is not the only issue. Once a factory windshield is replaced, other problems can surface. Windshield replacement compromises the factory seal, which is nearly impossible to replicate. Not only can an improperly replaced windshield lead to leakage and possible water damage, it can fail in the event of an accident.

Together with the air bags and seatbelts, the windshield plays a significant part of the vehicle’s safety restraint system (SRS). In an accident, the windshield works to maintain the structural integrity of the passenger compartment. As you can imagine, this is especially important in the event of a roll-over accident. It also cushions the occupant’s impact and prevents the possibly of being ejected from the vehicle. An improperly installed windshield could fail on all of these fronts.

An investigative report conducted by ABC’s 20/20 shed light into the dangers surrounding improperly installed windshields. It found that millions of windshields have not been installed properly and have contributed to serious injuries and even death.

So there are many reasons why a vehicle owner should opt for windshield repair early on. Ignoring the small and seemingly unintrusive rock chip could prove to be a mistake.

Sciatica Relief Murray Utah – Strategies

The sciatic nerve is the largest and longest nerve in the body. The sciatic nerve begins in the lumbo-sacral region (L-4 through S-3) of the spine, as five nerve roots from L-4 through S-3 leave the spine and merge into one large nerve that travels across the buttocks (the gluteal muscles) and down the back of the thigh and then into the lower leg, branching off just above the knee, at the back of the lower thigh, into the peroneal and tibial nerves, and finally giving rise to nerves traveling down into the ankle, feet, and toes. Consequently, sciatic nerve pain or sciatica may be felt at any point along the nerve route, expressing as lower back pain, pain in and/or across the buttocks, leg pain, particularly pain at the back of the leg, pain behind the knee, and even pain, tingling, and/or numbness into the feet and toes. Interestingly, sciatica is not a specific condition but a symptom of a problem at some point along the nerve route, usually but not always at the nerve root itself.Visit the site Sciatica Relief Murray Utah.

The ultimate sciatica pain relief strategy is ice. Ice is by far the most effective method for immediate and lasting sciatic nerve pain relief. Unfortunately, many people, including many medical experts advise heat for sciatica, in fact for almost all back pain, and that is generally the worst thing you can do. Inflammation and swelling is exacerbated by heat and reduced with ice. Most nerve irritation is the result of inflammation and/or swelling at some point along the nerve route, ice is the recommended treatment. Ice, using an ice compression brace is best but a plain old ice pack will also do just fine. Keep the ice on for as long as you can stand it, providing you have a sheet or thin towel between the ice and your skin to avoid frostbite. This is, of course, anecdotal and based on my experience over 15 major surgeries, 14 on my back…ice works best!

I am not going to get into why people recommend heat, beyond mentioning that proponents argue that heat helps with blood flow to the affected area, specifically nutrition and oxygen, and healing is enhanced, as a result. As you know too well if you experience sciatic nerve pain, when you are in pain the most important thing is relieving the pain! The healing will come later, let’s deal with the sciatica first!

The second sciatic nerve pain relief strategy is stretching. The piriformis muscle, and in particular what is called piriformis syndrome, may be the culprit when it comes to sciatica, or it may be at least partially to blame. The anatomy, where the sciatic nerve is located, along with a muscle imbalance, as the sciatic nerve is located in close proximity to the piriformis, may create the piriformis syndrome. A muscle imbalance may create pressure on the sciatic nerve, creating sciatica. A simple and easy to do stretch can help alleviate discomfort almost immediately.

The sciatica stretch is easy to do while seated in any chair. While seated in a chair, cross your left leg over your right leg so that your left ankle is resting on your right knee, bend forward at the waist pulling the left leg to the chest while continuing to bend forward. You will feel stretching outside of the left leg, as well as in the buttocks, stretching and leaning forward as much as any pain will allow. This stretch may be done to both sides, both legs, but the emphasis should be on the side where you are experiencing the sciatica. If the sciatic nerve pain is due to a muscle imbalance or piriformis syndrome you will feel immediate pain relief, if the pain is the result of a bulging or herniated disc, you may need to rely on other treatment strategies.

The third method is to change your footwear. Often people suffering from back pain in general, and sciatic nerve pain specifically, are wearing the wrong shoes. The importance of proper shoes cannot be overstated! Fashion? Forget about fashion! The only thing that matters when it comes to footwear is pain relief when you are in pain; and, when experiencing sciatica in particular. I recommend New Balance walking shoes because they are rated very high when it comes to heel cushioning; and, because they allow for varying degrees of width and a greater array of sizing alternatives, thus improving fit which translates into a better walking experience. The better fit and cushioning means less impact on the spine and that means less back pain generally and less sciatica specifically.
