Since around 41% of a household's energy is spent on heating and cooling, many homeowners want to improve their property's efficiency. One way to do this is by having window contractors update your windows. In fact, switching to the right option can cut costs by up to 24%. Here's a closer look at how to pick the best varieties.

Glass Panes

The more glass panes in a fixture, the lower the amount of heat loss and gain because the space between each pane acts as insulation.

For the highest insulation, ask a window contractor for double or triple glazing with low-emittance coatings or UV-blocking tints. You can also get windows with argon gas between their panes to further reduce temperature transfer. 

Opening Systems

A window’s opening mechanism affects the quality of its seal. Single- and double-sliding fixtures are the most common, but the friction caused by their movement wears on their seals. 

Hinged openings typically reduce air loss because the weight of the fixtures push them tightly against their frames when they’re closed. Such options include awning, hopper, and casement windows.

Window Frames

Framing materials can either help or hinder the unit's effectiveness at blocking airflow and UV radiation. Since metal acts as a thermal conductor, metal frames, such as aluminum, are the least efficient. Wood, on the other hand, doesn’t conduct heat. However, since it expands and contracts with temperature fluctuations, its efficiency is lost over time as it creates air leaks.

Manmade materials, like composite and fiberglass, are usually the most eco-friendly options. Both materials provide insulation by blocking heat exchange. They also require minimal maintenance.
