Frame Materials:
A window frames style is not what gets noticed. Because they seal out moisture and drafts, frames are almost as important as glazing when it comes in insulating ability.

Frame material types:
  • All vinyl frames:
    These are among the least expensive options and are the easiest to maintain They never need painting and some can even me make to look like stained wood. Early versions had many flaws. With improved additives, today's windows contain UV-stabilizers to resist the sun and modifiers to enhance toughness and flexibility.
  • Clad wood frames:
    These are wood frames covered on the exterior with a skin of aluminum or vinyl. Aluminum is stronger than vinyl and comes in more colors.
  • High-tech composites:
    For Example, a pultruded fiberglass material made by Marvin Windows for their Integrity line of window products.

As you go from vinyl to composites, the dollar amount increases along the way.

Glazing:
Window glass, called glazing, is the heart of a window. Today's energy-efficient windows come with glazing "systems" that can incorporate multiple panes of glass, gas fillings, and high-tech, heat sensitive coatings. Sorting through the options takes some effort, but it more than pays off in increased comfort and reduced energy costs.

Some Examples:
  • Low-E:
    An invisible lager of metallic oxide that reduces the amount of heat that passes through the glass.
  • Argon or krypton gas:
    These are gasses that pour thermal conductors so it slows the passage of heat through the glass package.
  • Heat mirror:
    This is made by suspending a sheet of low-e film between panes on insulted glass.

Low-E and Heat Mirror filter out ultraviolet radiation that faces furniture, rugs, and carpets. Simply by adding Low-E and Argon gas to your window usually qualifies the window for an Energy Star label from the Department of Energy.
