Best Energy Efficient Window Features

Choosing the right features is more important than just picking a window brand.

Double or Triple-Pane Glass

Modern windows use multiple panes of glass with insulating gas between them to reduce heat transfer. Double-pane windows already provide major efficiency improvements, while triple-pane options offer even better insulation for colder climates.

Low-E Glass Coatings

Low-E (low-emissivity) coatings reflect heat while allowing natural light in. This helps keep your home warm in winter and cool in summer.

Gas-Filled Insulation

Argon or krypton gas between panes slows heat transfer and improves overall insulation performance.

Insulated Frames

Vinyl and fiberglass frames provide better insulation than traditional aluminum frames.
