3 Tips for Picking Energy-Efficient Windows

3 Tips for Picking Energy-Efficient Windows

Installing energy-efficient windows doesn’t just lower energy bills. It can also improve your clients’ sense of comfort. At Pella of Decatur, we offer windows that meet or exceed ENERGY STAR® certifications in all 50 states.1

Learn how you can help your clients customize them through finding the right window style, frame material and glass options.

1. Window Style

The most energy-efficient windows come with sashes that close by pushing against the frame, according to the U.S. Department of Energy. This tight seal creates a lower air leakage rate, which impacts energy efficiency.

These styles include:

  • Awning, which is hinged at the top.
  • Casement, which is hinged at the side.
  • Fixed, which are hinge-free. These can be especially energy-efficient, since they are not designed to open.

However, these styles aren’t always effective depending on where you’re installing them. That’s why sliding, double-hung and single-hung windows are also popular styles. Because they open and close by sliding, the Department of Energy suggests they tend to leak more air compared to awning and casement styles.

There are ways you and your clients can make new windows more energy efficient, namely by choosing the right frame material and glass options. Here’s how you can do it.

2. Frame Material

The most energy-efficient windows are manufactured from vinyl, fiberglass and wood. Vinyl is the most affordable, while fiberglass and wood are premium materials.

Vinyl

Besides being low maintenance, vinyl windows are an affordable choice for energy efficiency. Boost comfort by installing multi-chambered frames, which slow heat transfer.

Fiberglass

Fiberglass windows are naturally strong and long lasting. They won’t expand or contract, which will often improve energy efficiency.

Wood

Wood windows are popular for their beauty, warmth and design flexibility. With Pella’s assistance, your clients can customize energy efficiency by using glass options like triple-pane or insulating gas between panes.

3. Glass Options

Dual- and triple-pane windows are the most energy-efficient glass options, particularly when combined with low-emissivity glass and insulating gas between panes. These options also keep out most of the sun’s ultraviolet rays, which can damage your flooring, furnishings and artwork over time.

Learn more about the glass options we offer at Pella of Decatur.

Advanced Low-E Insulating Glass

This option is recommended for most U.S. climates.

  • Dual-pane: Two panes of glass with Advanced Low-E protection and insulating argon between the panes. Stops 84% of the sun’s ultraviolet rays.
  • Triple-pane: Three panes of glass are also available on select product lines for greater energy efficiency. Blocks 86% of the sun’s ultraviolet rays.

AdvancedComfort Low-E Insulating Glass

This option is recommended for more temperate U.S. climates.

  • Dual-pane: Two panes of glass with Advanced Low-E protection and insulating argon between the panes. Stops 85% of the sun’s ultraviolet rays.
  • Triple-pane: Three panes of glass are also available on select product lines for increased energy efficiency. Blocks 87% of the sun’s ultraviolet rays.

SunDefense™ Low-E Insulating Glass

This option is best for very hot and sunny climates.

  • Dual-pane: Two panes of glass with SunDefense™ Low-E protection and insulating argon between the panes. Stops around 94% of the sun’s ultraviolet rays.
  • Triple-pane: Three panes of glass are also available on select product lines for increased energy efficiency. Blocks 95% of the sun’s ultraviolet rays.

Hot and sunny climates might also benefit from using tinted glass to rooms with hours of sun exposure. Bronze, gray or green tints block some of the sun’s rays and help keep rooms at comfortable temperatures.

NaturalSun Low-E Insulating Glass

This option is recommended for cold climates, like the far northern U.S. and Canada.

  • Dual-pane: Two panes of glass with NaturalSun Low-E and insulating argon between panes. Blocks 69% of the sun’s ultraviolet rays.
  • Triple-pane: Three panes of glass are also available on select product lines for increased energy efficiency. Blocks 73% of the sun’s ultraviolet rays.
