The right kind of replacement windows can dramatically improve your home’s energy efficiency and help decrease your monthly energy costs. But, have you wondered how this actually works? We take a closer look at how energy savings can be achieved with new windows.
The Energy Envelope
To understand the connection between windows and energy efficiency, we must first discuss the energy envelope. Every home has an enclosure consisting of the exterior walls, the attic and the slab floor or crawlspace. To maintain a comfortable indoor living space, these barriers have to be properly insulated. Under ideal conditions, these spaces will require only a small amount of heating or air conditioning to keep them comfortable. Low HVAC requirements equal low energy consumption.
Real-world conditions are different, however, as the occupants will need doors and windows for access, ventilation and natural lighting. Old windows are a source of heat loss during cold days (or heat gain during hot days) because of the single-panel glass, a naturally-conductive material. Combined with frame materials that expand and contract depending on the weather along with improper installation techniques, you’d have an indoor environment that allows leaks that push your heating and cooling systems to compensate.
This is where energy-efficient windows come to the rescue. These windows typically feature insulated glazing, a dual-panel glass system that minimizes conduction by separating the interior and exterior glass surfaces. A local windows company should have wood, insulated vinyl or composite frame options that complement the energy performance of the insulated glazing and make the indoor living space closer to ideal conditions.
Proper installation is also a factor. The window sashes have to be properly attached to the frame so they won’t allow gaps when closed. The frame itself should be properly leveled, attached and insulated to avoid leaks around the windows. Hiring a contractor that provides both quality replacement windows and the experience to ensure quality workmanship can ultimately result in energy savings.
