Glass is undoubtedly a reliable, versatile material, and very beneficial. At some point, however, it is bound to deteriorate and break. In this article, we decided to discuss the main types of Windows and cracks in glass, and the best ways to deal with them.
In addition, glass has long been a proven solution for securing our homes and commercial properties. However, some areas require higher security or security. To ensure safety, quality workmanship and the choice of glass used is a major consideration. Given standard glass easily broken when hit from accident, need extra strength, heat resistance and high level of safety glass rise to meet different application requirements. So we will also make suggestions on this.
Types of window cracks
Cracks in Windows are a volatile problem. Some will assure you that they can be repaired and that there are ways to temporarily slow the spread of cracks in Windows (such as super glue or tape). However, these methods only slow down rather than prevent cracking. Eventually, window cracks will spread and completely destroy the window, so it is best to replace the window ahead of time. But did you know that your Windows may develop different types of cracks? Here are some of the most common types of window cracks that can lead to window replacement.
1. Impact cracks
Impact cracks are caused by objects or debris striking Windows or glass surfaces. These cracks are often caused by wayward toys and balls that end up being thrown at Windows. Stormy weather can also strike cracks when branches, pine cones or other tree debris are blown through Windows.
2. Stress crack
Like pressure cracks, stress cracks can be caused by significant changes in weather and outdoor temperature. However, unlike pressure cracks, these usually occur very slowly and gradually. A stress crack usually begins at the edge of a glass plate, then grows larger over time and extends throughout the glass. Closing Windows can also cause stress cracks.
3. Edge cracks
Edge cracks look almost identical to stress cracks. They also originate at the edges of Windows and spread out in a zigzag pattern. However, the edge crack was not due to any change in temperature, but to damage to the edge of the window. If you want to know whether the crack is caused by thermal stress or damage to the window edge, check the window edge for small “oyster” fragments. They are often hidden under window seals, making them hard to find. Another way to tell is to look at the direction of the crack. Stress cracks are found throughout the window, and edge cracks tend to extend outward from the point of damage. In either case, edge cracks or stress cracks usually result in window replacement.
4. Pressure crack
If you have double glazing or insulated glazing, you need to worry about pressure cracks. Pressure cracks seem to have popped up. However, the root cause is usually a dramatic change in environmental pressure due to changes in weather. Windows installed at very high or very low altitudes are at risk of developing these cracks. Pressure cracks are most likely to curve in an hourglass shape, so this is another way to identify them. If you believe your window has pressure cracks, replacing the window may be the only solution.
5. Spontaneous rupture
In rare cases, Windows may break of their own accord. This happens most often with tempered glass, especially if modifications have been made to tempered glazing glass. If not made properly, the chemicals can evaporate onto the Windows. You may not notice any problems until one day the glass breaks. In this case, replacing a window is not only the only option but the manufacturer of the replacement window should be carefully chosen.
Types of cracks in automotive glass
1. Tiny chunks
A chip is a crack in a motorcar glass that can be repaired. Small chips measure about 40mm or less. These are found on windshields, mirror glasses, and skylights mostly as debris. Here are some of the types of automobile glass chips:
a) Bull’s eye
This type occurs when a small sharp rock strikes a windshield. In certain cases, a little piece of glass may fall out and create circular fractures.
b) Star-shaped pattern fragmentation
This crack results from hitting the windshield with something sharp. In some cases, there will be falling pieces but depending on the intensity of impact only tiny ones will fall off. The star shape indentations quickly get upgraded.The sooner this vulnerability is addressed, the better.
c) Half-moon fissure
With this kind like bull’s eye crack it looks semicircular to an extent.
d) Trefoil leaves
The bottom layer of the glass breaks apart along this line.
e) Rim cracking
In case it occurs near the lining of windscreens (or near edges), these cracks would happen to vehicles . If left unattended, they tend to grow quickly in size as many as to form bigger cracks.An obstructed vision due to a crack becomes a danger on roads for any driver.
f) Mixed rest
The crack is what forms as a result of both star breakage and bull’s eye impact most times.This happens when small stones hit windscreen speeding at high rates.Small parts need correction immediately because they may widen into large front/windshield glass cracks.
2. Big splits
A scratch had been distinguishable from other chips since its depth on the front glass of a car (caused by hitting it with something sharp) was higher than 14”. The PVB may be damaged and this is an immediate contender for a replacement. It would be helpful to seek solutions from professionals who are available in your area to help you restore your car’s front glass.
3. Internal cracks
External cracks appear outside of a vehicle’s glass, but there can also be internal ones which are called stress cracks that come as a result of sudden temperature changes. One can find out how to crack his/her own car’s window by pouring hot water after driving a long time in cold temperatures. Since this stress crack is located internally within the glass, one can feel it by moving their finger (or pen) over the crack. In this case, the best decision will be made in favour of changing the vehicle glasses because they tend to widen with time.
How to repair broken windows
Window cracks are not something that one would want to have happen, but if you do, it is good that you know what to do about window cracks repair. What happens after that depends on the size of the crack and type of window in question. For minor cases, fixing the crack might only require a solution like glass epoxy. However, when insulated Windows break; they often need replacement. It is advisable for one to call a glass repair professional for inspection and recommendations in case there is any urgency associated with a window’s damage or spoilage. The kind of glass at hand as well as how much and where exactly is it broken should be checked by your technician.
The best category 2 of glasses
1. The reinforced glass
This class of glasses can be used basically because of safety requirements. These glasses are made through controlled heat treatment or chemical processes such as tempering. During tempering, compresses occur on the outer surface while tension builds up internally making it difficult for this type to break easily unlike other ordinary types referred to as annealed glasses. Instead, it shatters into chunks that are harmless and non-cutting unlike typical ‘annealed’ glass which does fracture even into many small pieces Some examples include toughened glass in shower doors, motor Windows architectural glazing doors and windows refrigerator doors & shelves Dive masks etc.
2. The laminated glass
Laminated glass is a certain type of safety clear material made of two or more layers of transparent material that are bonded together with one layer of plastic sandwiched between them. Laminated glass is commonly used in windscreens and its main advantage is that it does not scatter into many pieces when broken to prevent injury. Additionally, laminated glass stops UV rays from penetrating hence reducing the noise coming through windows making it perfect for residential and commercial purposes.
Moreover, these glasses live longer than normal ones because they are less likely to crack over time. However, laminated costs more than ordinary glass; nevertheless, it is worth spending money on enhancing security and convenience in your home or office.
