What Makes Your Window Energy-Efficient?

If you’re in the market for new windows, you might be prioritizing material and style. However, one important consideration you should put at the top of your list is energy efficiency. An energy-efficient window reduces the strain on your heating and cooling systems. This can help you save money on your monthly energy bills as well as lessen your carbon footprint.  

What Makes Your Window Energy-Efficient?

Renewal by Andersen® of Sacramento, a top provider of casement and picture windows, shares an overview of the components of an energy-efficient window. 

Low-E glass

Energy-efficient windows have low-emissivity (low-E) glass. This incorporates a specialized coating that minimizes the amount of heat passing through the glass while allowing light through. This also reduces the U-value of the glass. The U-value measures how well a window prevents nonsolar heat loss or gain. The lower the U-value, the greater a window’s resistance to heat flow and the better its insulation.

Double-Glazed Windows

Aside from the low-emissivity coating, energy-efficient windows have more than one pane of glass. This provides better thermal performance than single-paned windows, thanks to the inert gas fill in between the panes. Regardless of the climate, windows with double glazing are capable of minimizing heat transfer, ensuring more consistent indoor comfort while saving on energy costs.

Good Weather Seals

Many homeowners may not notice it, but air can escape or enter your home through the gaps and cracks around sashes and frames. That said, an energy-efficient window should have good window seals. Windows with compression seals, such as those fitted to casement and awning windows, tend to have the best air infiltration performance. Thanks to recent window technological advances, seals have improved.
