Understanding Different Window-Pane Configurations

You don’t have to shop around for windows in Nashville too hard to learn that they come with single, double and triple panes (or more). The number of glass sheets in each unit usually determines its insulating quality. Generally, the more panes the window has, the better it is at reducing the transfer of heat (and sound), right? Read on to find out how true this is.

Single-Pane Windows

Any trusted window company, including Renewal by Andersen® of Nashville, would say that single-pane units are not insulated. They’re the least efficient because they don’t have the benefit of an inert gas to minimize heat transfer between your home and the outside. This is why the level of comfort in the rooms they serve fluctuates, forcing your HVAC system to work extra hard. In turn, they cost you more money on energy just to regulate your indoor climate.

Double-Pane Windows

Double glazing is the industry standard today. Two-pane window configurations allow for gas filling. In addition to trapping heat within the room, the insulating gas helps keep the unit warm enough to resist condensation, too.

Not all replacement windows with two panes are equal, though. When there’s not enough room for the gas, the unit’s energy efficiency diminishes. But when there’s too much space separating the panes, the rate of heat loss goes up due to convection.

Triple-Pane Windows

Three panes are better than two layers of glass. However, they’re only worth buying if you live in an extremely harsh climate. The triple-pane glazing system dramatically increases the cost of the individual unit to the point that it’s no longer practical to purchase.

In most Tennessee homes, double-pane windows will suffice to help regulate the indoor climate. Besides, the right kind of glass coating allows double-pane units to perform nearly as good as triple-pane ones for less cost.
