Double or Triple Pane Replacement Windows?

Shopping for replacement windows in Seattle, WA can be a bit overwhelming. There are so many options and technologies on the market, especially when you want to find new windows that offer the best energy efficiency. To help make the process a little easier here is some more information about double pane and triple pane replacement windows.

What are Double Pane Windows?

With double pane windows, instead of one pane of glass, there are two. The void between the panes is filled with inert glass and sealed around the edges for optimal efficiency. Double-pane windows are now the standard on most products and work well for most moderate climates.

What are Triple Pane Windows?

As you have probably guessed, instead of one pane or two panes, triple pane windows have three panes of glass. The added layer increases the amount of insulating space to help improve efficiency. These windows also use a more expensive inert gas that performs better in smaller spaces. These glazing units are best for areas with very cold winters because they help minimize heat loss. But the downside of triple pane windows is the added cost and the weight.

Are Double or Triple Pane Windows Better?

If double pane windows are good, you might think that triple pane windows are automatically better. But it is much more complicated than that. Deciding on the better solution comes down to where you live, the average winter and summer temperatures, and whether or not the investment equates to the right amount of energy savings to make the additional pane worthwhile. Although triple pane windows can improve efficiency, it can take 20 to 25 years to pay them off with energy savings. This is why many homeowners choose other glazing technologies to improve insulation instead of going straight for the extra pane of glass.

Other Glazing Technologies that Improve Efficiency

Adding another pane is not the only way to improve insulation on new windows. Another option is to upgrade the inert gas between the panes. Argon, krypton, and xenon are the most common. These are odorless, colorless, non-toxic gasses. But the reason they work to improve insulation is they have more density than air and can reduce heat transfer coming through the glazing unit. The different gasses perform better at differing widths so you can find the most cost-effective solution.

Another option is tinted glass or Low-E coatings. Window tints can help block certain segments of light that cause heat transfer. This also reduces the amount of visible light entering the home and would be a good solution for bedrooms and entertainment areas. Also, Low-E glass has ultra-thin metallic coatings applied to certain surfaces of the glass to reflect unwanted heat gains. These block radiant heat without blocking visible light.
