The process of window glazing is important to understand if you are in the market for replacement windows for your Tacoma, WA home. Window glazing has come a long way since the days of one pane of glass.

The modern energy-efficient window has a glazing process, incorporating multiple panes of glass, gas filler, and heat-sensitive coatings. Here’s an explanation of window glazing applications by type of window.

Double-Pane Insulated Glass

These dual-pane windows are most commonly installed in homes. These windows have a layer of inert gas, typically argon, sealed between the inner and outer panes. The gas is a poor thermal conductor, so it slows the passage of heat through the glass, keeping a home’s warmth inside.

Triple-Pane Insulated Glass

Beyond the double-pane window, you can opt for the even more efficient triple-pane window. It has two layers of gas within the frame. Triple-panes are excellent performers in colder climates and block a tremendous amount of outside noise. They are, however, costlier than dual-panes.

Low-E Coatings

Adding panes and gas-filled spacers is one way to get a more efficient window. You can also achieve efficiency with low-emissivity (Low-E) coatings. The coating is an invisible layer of metallic oxide that reduces the amount of heat that passes through the glass. Virtually all new windows offer this feature.

When heat or light energy is absorbed by glass, it is either convected away by moving air or reradiated by the glass surface. The ability of a material to radiate energy is called its emissivity. All windows emit heat in the form of long-wave, far-infrared energy depending on their temperature. This emission of radiant heat is one of the important components of heat transfer for a window. Thus, reducing the window’s emittance can greatly improve its insulating properties.

Low-E coatings will add cost to your windows, but they will give you a great return on your investment by lowering your energy costs. The additional cost is really minimal, considering all the benefits it brings.

Should Your Windows Be Glazed?

Glazing a window is one of the best things you can to do maximize the energy efficiency of your home. Aside from doors, poorly functioning windows are usually the biggest reason for heat loss. There are times when the glazing “fails,” and the window needs to be re-glazed. You may save yourself a lot of time and trouble by opting for new replacement windows instead that are glazed.
