What Are the Types of Insulated Glass Windows Used at Homes and Commercial Buildings?

Insulated glass windows or glazed glass windows are a process of putting two or three panes of glass together as a single unit. It involves leaving some space in between those glass in order to input air, krypton, and other gases that mitigate heat, sunlight, and more.Glazed windows have been on for decades, right before people started figuring out new ways of saving energy cost as they continue to triple yearly. Insulated windows mean a warm bed during winter because of its ability to trap in air. They are also expected to save us from intense weather conditions during the summer as well. Instead of spending more money powering the air conditioner or an HVAC system, it makes more sense installing glazed window.


What types of windows do we have in the market?

Windows is an essential part of every building arrangement, especially for commercial buildings and homes where people spend most of their time. They provide for ventilation, aesthetic value, lighting, scenery, and clear peace of mind. Some of the windows we have grown to appreciate started from wood, aluminum, fiberglass, plexiglass, glass panes, curtains, and today we have the glazed glass.
Glazed glass is far more expensive and more protective than the rest. It offers security from a lot of stuff we humans want to hide behind like the sun, cold, insects, privacy, robbery, burglary, and much more. Glazed glass is produced mostly in factories all over the US that have the right machines to put them and their features in place, like tints, coatings, reflective sprays, etc. For more types of glass windows click here.
Types of insulated glass for homes and commercial buildings
Glazed glass work with an R-value or U-factor as it is popularly called. The lower the U-factor, the better the window can insulate against heat or cold. A single glass pane can carry an R-value of 1, which is equivalent to U-1. But two or three panes give a U-factor value of U-0.5 and U-0.33, respectively.
However, there are other ways an insulated glass window U-factor and R-value can be improved upon like inert glass fillings, tinting, and low E-coating, which we will be talking about much later.
Single insulated glass windows
Here is a glass window that is glazed with only one pane. Meaning it can take on more heat inside and light too. It is far cheaper than the other glass panes we are going to talk about here. It involves glazing a single sheet of glass by filling it with inert gas, which can make it resistant to heat, sun, or cold in general.
Double or triple glazed insulated glass
As we have rightly mentioned, these types of insulated glass are far more expensive and offer more protection. In between, each space is filled with air or gases that help reduce the pressure of heat and cold from inside and out of the home or commercial building. Those who choose to use them need to trap more air inside than they do outside. People who purify the air they breathe would rather have this type of protection together with their filtration system. Someone with an HVAC system can still use them to trap the cold inside even when it is not put on.
For every country, city, and state, there are building codes to adhere to. The same applies to the use of insulated glass. For example, in the US, areas of a specific climatic condition are requested to use a double or triple-pane glass in their homes. If they can't afford that, some other solutions are provided for them like:
Low E-coating insulated glass window
E-coating is a metallic spray or paints on the glass for them to show low emissivity to the display of light and the resistance to heat in the room. They come in two forms, which are majorly to reduce the building's SHGC ratings. However, they are highly recommended by the US Department of Energy as very efficient in transmitting less heat when they use them with glazed glass panes. Don't worry, they are not visible except under a special light, and they will not blur the view from your window either. They are mostly combined with two or three-pane glazed windows to give out the best effect.
Tinted glass windows
Whether you are using the standard or the high-performance tint for your glazed window, you have to consider that they all perform the same function at different lengths. Standard means you get to have some privacy, low light emission into the room, but it has less resistance to heat. High performance comes with more light in the room, but it is far more effective in reducing the amount of heat that makes it from UV rays.
Reflective glass windows
What most people do when they are trying to save costs is to use a reflective glass window. That way, the light bounces off the outer glass panes and leave with low emission into the room. They can be of any color between gold, silver, or bronze. Still, they provide much more in their mirror-like display that allows less heat to come into the room or commercial building. They are less expensive to procure if compared to tinted or low E-coating.
Inert gas fills and spacers
Gas fills and spacers are the gas and the amount of space present in an existing glazed glass window. Usually, between 1/4 and 1/2 space is required to fill the argon or krypton gas that allows for effective heat insulation on your glazed glass. The amount of each use goes a long way in reducing the U-factor of the glass. Argon is far more expensive to use, though.
In conclusion, homes and commercial building owners have to define the type of insulation they want for their loved ones and employees. The budget doesn't have to be large to meet up with the basic requirements of certain city building codes. However, each will go a long way in reducing the cost of energy at homes or commercial buildings.
