Building terminology can induce confusion in the average homeowner, particularly when a phrase has multiple meanings. For instance, triple set, when referring to windows, may mean one of three things, each a different type of window. The process of building a triple set window ultimately depends upon the type of triple set window in question. Keep in mind that building windows requires a number of special considerations, including moisture protection and heat conductivity.
Triple Set Windows - The term “triple set” may refer to three types of windows. A single window frame that houses three windows holds a “triple set” of windows because it consists of a set of three windows. A triple-glazed, or triple-pane, window contains three panes of glass to reduce heat loss and moisture intrusion. The set of three panes in a triple-glazed window constitutes a triple set of window panes. Lastly, “triple set” may refer to a window frame with three areas for setting glass. In these windows, you can install panes in the front, middle or back of the frame. These three options comprise a "triple set."
Considerations - There are many things to keep in mind before building a window. For instance, a windowsill must direct water away from the window to prevent moisture from penetrating the home. This requires a slope. Furthermore, you need some kind of blocking device, such as a rubber strip or a locking mechanism, that prevents water from leaking under the glass. In cold regions, a single pane of glass provides little to no protection from winter weather. To protect against the cold, your window needs multiple panes of glass, separated by air or another gas, and insulation at the sides. Finally, building and installing a window require cutting into your walls. If you have no construction training or experience, consult a structural engineer or licensed contractor to avoid damaging your home.
