Window Glass Types

Dec 13, 2022

Windows are synonymous with glass, so it may be easy to assume that all glass is the same. But that is not the case. There are a variety of glass options to choose from when it comes to new windows for your home. So where do you begin? We understand that shopping for windows can be an overwhelming process, so below we outline some of the common differences in window glass so you can better identify the perfect choice for your Columbus, Ohio home.

Low-E Window Glass

While windows typically look clear, there is often a very thin coating on the glass that helps with its energy efficiency. This thin coating is known as Low-E or Low-Emissivity coating, and it helps regulate the heat and cool transfer through the glass. Different windows can have different amounts of Low-E coating, which will increase or decrease the energy efficiency of the window. Homes in sunnier climates may want to utilize a higher Low-E glass in order to reflect more sunlight and keep homes cooler. Homes in more temperate climates may go with a standard Low-E coating to cover both hot and cool temperatures. Low- E glass can help maintain the energy efficiency of your home, so it is important to find the right option for the energy efficiency you desire.

Double vs. Triple Paned Window Glass

In the past, single-paned windows were very common; however, they are typically far from energy efficient. The current industry standard for windows is double-paned, meaning there are two panes of glass protecting the interior of your home from the exterior. Some manufacturers offer a triple-paned option for windows, which would add a third pane of glass between the interior and exterior of the home. While triple-paned windows are often slightly more energy efficient, they are also more expensive, so it is important to weigh the options and see what makes the most sense for your window replacement project.

Gas Filled

Above we mentioned that windows are typically double (and sometimes triple) paned, so what is between those panes of glass? Different manufacturers may offer some different options; however, the most common filler is argon gas. Argon is heavier than normal air, so it helps slow the heat and cool transfer between the window, making it more energy efficient. Some windows may offer an option with krypton gas, which is similar to argon in that it assists with energy efficiency, but it is also more expensive, so it is important to determine if the extra cost is worth the upgrade in efficiency.
