Types of Glass Phoenix AZ
Laminated glass consists of polyvinyl butyral (PVB) layer bonded together between two panes of glass under heat and pressure.
Once sealed together, the glass is a single unit and looks like normal glass. Similar to the glass in car windshields, laminated glass may crack upon impact, however the glass fragments typically stick to the protective inter-layer rather than falling free and potentially causing injury. Laminated safety glass is the best barrier against break and enters as well as smash and grab style crimes. Laminated glass when impacted breaks exactly like the windshield of your car, cracks but is held in place by the vinyl laminate layer. Anyone attempting to gain unauthorized access to your home or business would have to break through two pieces of glass and the flexible vinyl layer, which will dramatically increase the time it will take to gain entry to your property. In conjunction with an alarm system, laminated glass can reduce the number of successful break-ins. The ultraviolet filtering performance of the protective inter-layer helps protect valuable furnishings, displays or merchandise from the fading effects of the sun’s UV light.
Tempered glass is, under equal pressure approximately four times as strong as annealed glass. It resists breakage by small objects traveling approximately twice as fast as objects which break annealed glass. Tempered glass is also able to resist higher temperatures (200 ° F – 300 ° F) which would cause annealed glass to crack. Our tempered glass is a safety glazing material that is manufactured to meet the requirements of the ANSI Z97.1 Standard and Federal Standard CPSC 16 CFR 1201. Federal Standard CPSC 16 CFR 1201, as well as state and local codes, requires safety glazing material where the glazing might reasonably be exposed to human impact. This includes doors, tub and shower areas, side lite areas, and certain windows. When installed to older doors that currently do not contain safety glass we must replace all non-safety glass in the door opening (all glass within main frame of door) order to bring the door to current code or we cannot replace any of the glass. Tempered glass possesses the basic visual qualities of annealed glass. The induced stress condition sometimes produces a slight bow in tempered glass lites. Tempered glass that has been manufactured in a vertical tempering oven contains small surface depressions resembling dimples along one edge. These marks are caused by the pointed metal tongs which support the glass during its passage through the oven. Glass which is passed horizontally through an oven may contain a very slight surface wave caused by contact with the rollers. The waviness can sometimes be detected when viewing reflected images from a distance.
Annealed glass is glass without internal stresses caused by heat treatment, i.e., rapid cooling, or by toughening or heat strengthening. Glass becomes annealed if it is heated above a transition point then allowed to cool slowly, without being quenched. Float glass is annealed during the process of manufacture. However, most toughened glass is made from float glass that has been specially heat-treated. Annealed glass breaks into large, jagged shards that can cause serious injury, and thus, the reason it is considered a hazard in architectural applications. Building codes in many parts of the world restrict the use of annealed glass in areas where there is a high risk of breakage and injury, for example in bathrooms, in door panels, fire exits and at low heights in schools or domestic houses. Annealed glass is probably the most common glass around, however, it also has the potential of being one of the most dangerous glass types if used incorrectly. Many of the older homes in town still have annealed glass in their doors, this is a dangerous situation. Annealed glass in doors can break just by closing the door, or if someone were to walk into the door the glass would break into large jagged shards that could potentially cause severe cuts. When replacing annealed glass in doors it is required that the "door opening" be brought up to code, thus requiring all glass within the main door frame be replaced with safety glass. We recommend all the glass in your home be inspected and brought up to current code.
Dual pane windows are made up of two pieces of glass separated by airspace that are physically sealed together, and cannot be separated. Dual panes can be made up of countless combinations of glass and spacers to make the overall thickness anywhere from 7/16" all the way up to 1 and 1/4". Dual panes may also have tinted glass on the outer pane please note the tint when calling for an estimate. In general the more airspace that there is in the unit the better the insulation the window provides. There are other factors that can improve the efficiency of of your windows. Among the best options you can have on your windows is a low-E coating. This will allow your windows to reflect much of the heat and UV radiation away from the inside of your home.
This glass reflects up to 90% of long-wave radiation, which is heat, but will let in short-wave radiation, which is light. Low E glass is coated with a film that bonds a microscopic, transparent, metallic substance to the inside surface of the double-pane or triple-pane window working like a sunblock to protect your home from the UV rays and making it more energy efficient.
This is a type of glass that you cannot see through. This glass can be made by frosting or sand etching the surface to give the glass a white or milky look. This type of glass is often used in bathrooms to obscure a view into the room, but still let in light. This type of glass has a few purposes, it can be used to achieve privacy, decoration or light diffusion. At the factory a design can be pressed into the glass during the rolling process making the glass translucent, allowing light to pass through, but also creating a blurred surface.
