What does the Energy Star Symbol mean on my Windows and Doors

By Gates Dearen

You see them everywhere; you know the big E symbol. It’s on refrigerators, computers and yes, even windows and doors. Have you ever wondered how it came about? Better yet, have you ever really thought about what it means to you? In this article, I will explain how the Energy Star rating came about, how it’s used and how your choices affect your pocket book.

The Big E means Energy Star Compliance


The Energy Star ® label is the symbol used to notify you that a product has met a standard developed by the Federal government.  The program was first developed in 1992 by t

he US Environmental Protection Agency (EPA) as a method to identify and promote products that are energy efficient. This is not a mandatory program enforced by the government. Companies can choose to either meet or not meet these standards. The important point here is that these standards give consumers a way of comparing products based on this standard. Look for building materials and products that carry an Energy Star label. They have met very specific standards set by the U.S. Environmental Protection Agency and the Department of Energy.

Three qualities of ENERGY STAR Windows and Doors:
Most ENERGY STAR-qualified products have common features. However, these features are not required. To learn what makes it ENERGY STAR click here.  These windows and doors have some or all of these features:
  • Quality Frame Materials
  • Multiple Panes
  • Low E Glass
  • Gas Fills
  • Warm Edge Spacers
ENERGY STAR-compliant windows and doors are made from a variety of materials. These materials can determine the durability, maintenance and to some extent the look and feel of the windows and doors. Here is a list of materials provided by EnergyStar.gov web

site. This list is provided in alphabetical order and not in a way that suggest which is best.

Aluminum windows and doors are durable, low maintenance, recyclable, and typically have at least 15% recycled content. These designs typically include thermal breaks to reduce conductive heat loss through the metal.
Combination windows and doors use different materials separately throughout the frame and sash to provide optimal performance. For example, the exterior half could be made of vinyl while the interior half could be wood.
Composite windows and doors are made of various materials that have been blended together through manufacturing processes to create durable, low maintenance, well-insulated windows.
Fiberglass windows and doors are strong, durable, low maintenance, and provide good insulation. Fiberglass windows and doors can be either hollow or filled with foam insulation.
Vinyl windows and doors are low maintenance and provide good thermal insulation. Sections may be hollow or filled with foam insulation. Wide vinyl sills are often reinforced with wood or metal.
Wood windows and doors are strong, provide good insulation, and are generally favored in historical neighborhoods. The exterior surfaces of many wood windows are clad with aluminum or vinyl to reduce maintenance.

What Does All This Mean To You?


Windows and doors that meet the Energy Star ® rating are typically 10 to 20% more energy efficient than non-rated one. This means, you'll save money, and you will also be help
