Ask the Window Supplier: Are Multiple Panes More Energy Efficient?

Professional window suppliers receive a great many questions from customers, and here at Rocky Mountain Windows & Doors, we’re always happy to provide expert answers and advice.

One common source of confusion stems around the difference between single-pane, double-pane and triple-pane windows. More specifically, homeowners want to know if multiple panes are more energy-efficient and if more panes are worth the investment. If you’re curious, read the following explanation from our professional window supplier team.

Single-Pane Windows

Single-pane styles have just one sheet of glass set into a frame. These days, they’re typically found only in older homes that haven’t been renovated, as builders don’t use them for new constructions.

Why not? While a single sheet of glass may be good enough to block the wind and provide a clear view, it isn’t an effective insulator. Single-pane windows are particularly drafty and prone to condensation, making them the most inefficient type available.

Double-Pane Windows

Double-pane styles, which feature two sheets of glass fitted into a frame, are much more energy-efficient than those with a single pane. The efficiency boost is due to the pocket of air trapped between the two glass sheets, and the effect can be enhanced with an infill of argon gas.

Professional window suppliers often recommend double-pane glass, as the reduced heat transfer and air loss they provide ensures homeowners see significant energy savings. Plus, with two panes of glass, condensation is much less of a concern.

Triple-Pane Windows

Triple-pane styles, as the name suggests, have three sheets of glass separated by air or argon gas. And yes, they’re the most energy-efficient type – but they’re also the most expensive, coming in at a price that’s up to 30 percent higher than double-pane glass.

Despite the cost, professional window suppliers recommend triple-pane glass to homeowners who want to increase their property value by as much as possible. They can also be a good idea for those who plan to remain in their current homes for at least a decade, as they’ll be able to recoup their entire investment.

Installing Energy Efficient Windows

If you want highly energy-efficient windows, double- or triple-pane glass isn’t your only option. You can also choose low-E3 glass, with a triple coating that offers optimal protection against solar heat gain. Warm edge spacers are also available, which help protect the glass edges from air loss.
