Choosing a new type of window for your home involves several factors. Besides the price, you want to be sure that the window glass provides insulation and is energy efficient. Many window glass types even help block harmful UV rays, as well as act as a sound buffer to the outside world. These are 4 of the main types of window glass you will have to choose from when installing new windows in your home, and each type offers different benefits that need to be taken into consideration. Here are 4 different types of windows and what they can do for you!

Insulated Glass Windows

Insulated glass windows are made up of two or more panes. These panes are separated by spacers and sealed hermetically. The space between the glass panes insulates the window. These are excellent for regions where extreme cold or hot temperatures are experienced. While an excellent option, insulated glass windows do cost up to twice as much as other window options.

Gas-filled Windows

A gas-filled window is another type of pane. The gas used is often argon or krypton. They offer much more insulation than the insulated panes described above. When combined with Low-E glass and heat-absorbing tints this type of window has an incredibly high R-rating. The gas does leak out, however, at around a rate of 1% per year.

Heat-Absorbing Tint Windows

If you want to get glass that reduces glare, look for a type of window made with heat-absorbing tint. It keeps out solar heat and makes an excellent choice for office environments. It can be combined with gas-filled and insulated windows.

Low-Emissivity Windows

Low E glass or Low-emissivity panes are coated with a special coating that helps control heat as it comes into the window. These are great for cold climates. You would be able to use less heat with the help of these windows so they are an excellent investment.

There are two basic types of Low-E products. One is a reflective coating glass which reduces the amount of solar light that transmits through the window. This reduces glare as well as the transfer of solar heat indoors. Another type is spectrally-selective, a coating which filters about 70% of heat without blocking any light.

When you choose the glass you want, you want to think of your home’s needs for heating and cooling. Insulation panes make good sense for any climate that experiences both hot and cold weather while the Low-E glass products are superb for cold climates.

You also want to think of the lighting that you need in your home. Different types of glass will allow more or less light into the home. If you have furnishings or carpets that could become bleached by the sun you will want to purchase a window that deflects the sun’s UV rays.

Many of these types of windows can also be combined, to get the R-rating that you’re looking for while also balancing cost.
