What Goes Into an Energy-Efficient Window

Choosing energy-efficient window replacement units is ideal for homeowners for various reasons–some people might be keen on energy savings while others are interested in doing their bit for the environment. But what exactly goes into an energy-efficient window?

The Right Components

First of all, an energy-efficient window has to have the right components. Window performance is the sum of its parts, after all. With the right parts, a window can effectively be energy-efficient.

These parts include:

• • Quality Framing Material – Window frames designed to limit thermal transfer are ideal in making energy-efficient windows. Fibrex®, for example, is 700 times better at insulating compared to aluminum. This means a window with Fibrex frames will be more energy-efficient than those made of aluminum.
  • Multiple Panes – Dual panes improve energy efficiency in windows by helping stunt heat transfer, working with gas fills to keep indoor heat in and outdoor heat out.
  • Low-Emissivity Glass – Low-E glass is window replacement glass fitted with a microscopically thin layer of metal oxide, filtering out infrared rays from the sun to keep passive heating at bay without impeding natural light.
  • Gas Fills – Paired with dual-pane construction, gas fills like argon and krypton are designed to slow down the transfer of heat from one window pane to another. This is possible because these gases are dense.

• Warm Edge Spacers – While designed to primarily keep window panes at the correct distance apart, warm edge spacers also insulate, preventing heat transfer from pane edges.

The Right Installation

Even the most energy-efficient windows will not be able to perform their best when not properly installed so always make sure that you are getting replacement windows only from trusted experts in your area.
