What Makes a Window Energy-Efficient? – Part 3: Energy-Efficient Features in Windows

Choosing a window made from the right material and in a particular style can greatly improve your home’s energy efficiency. However, certain features also contribute, ensuring the best application of ventilation, insulation and illumination for your property. The following is a rundown of some of the most energy-saving window features.

  1. Weatherstripping

Weatherstripping refers to the strips of rubber or vinyl found on the edges of the window frame. When the window is fully closed, the weatherstripping acts as an insulator, sealing off gaps between the sash and the frame to prevent moisture, wind and dirt from getting inside. Having good quality weatherstripping helps prevent unregulated outdoor air from getting inside and affecting the stability of indoor temperatures.

  1. Low-E and Reflective Coating

Low-emissivity and reflective coating enables a window to block heat from the sun and reflect heat back inside your home. They differ, however, in that low-E coating does not impede the level of natural light a window lets in.

  1. Multi-Pane Glazing & Gas Fills

Multi-pane glazing means more than one layer of glass is used in a window. Using several glass layers improves insulation because less heat is transferred. This function is further complemented by heavy gas (usually argon or krypton) that fills the space between the layers of glass and slows heat transfer.

  1. Window Treatments

Though not exactly a window feature, the use of window treatments improves energy efficiency by further preventing heat inside from getting out and heat outside from getting in. With air leakage further kept to a minimum, indoor temperature remains stable.

Windows look great but they can be greatly functional as well. Making the effort to choose energy-efficient windows when you’re looking for a replacement will help you address more than one need, ensuring you make the most out of your investment.
