Double Pane vs. Triple Pane Windows in Northern Virginia Homes

How Double Pane And Triple Pane Windows Differ

The jump from double pane to triple pane sounds simple, but it changes the weight, price, and performance of the window in ways that matter on site.

A triple pane unit adds a third sheet and another insulating cavity, which can improve thermal performance if the frame and installation are up to the task.

A shaded bedroom on a quiet street has different needs than a west-facing family room above a driveway or road.

A high-performing window with the wrong solar characteristics can still leave a room uncomfortable in July.

A Practical Way To Match The Window To The House

Triple pane starts to make more sense when one or more of these are true:

• the room is hard to heat or cool,

A well-selected double pane unit can outperform a poor triple pane install every day of the week.
