Why Low-E Argon Windows Are a Must-Have in Arkansas (And Why Cheap Glass Just Doesn’t Cut It)

When it comes to replacing your windows in Arkansas, not all window glass is created equal. Many homeowners don’t realize that some contractor-grade vinyl windows come with plain clear glass—offering little to no insulation against the intense summer heat or the chilly winter air.

At Southwest Window & Door, we proudly install Wincore 5400 and 7700 series windows, which feature Low-E glass with argon gas insulation. Here’s why that matters—and why you should never settle for just "clear glass" in your window package.

1. What Is Low-E Argon Glass?

Low-E (low emissivity) glass is coated with an ultra-thin layer of metal oxide that reflects heat while letting in natural light. It keeps your home cooler in the summer and warmer in the winter.

Argon gas is a dense, non-toxic gas sealed between the panes of glass. It reduces thermal transfer far better than regular air, improving the energy efficiency of your windows significantly.

Together, Low-E glass and argon gas create a powerful insulation combo—designed to protect your home from temperature swings, UV damage, and sky-high utility bills.

2. The Problem with Clear Glass Windows

Many budget-friendly window companies and contractors install windows with no Low-E coating and no argon gas—just plain double-pane clear glass. While that might save a few bucks upfront, it does very little to:

• Block heat from entering your home in summer

• Prevent cold drafts during Arkansas winters

• Protect your furniture and flooring from sun damage

• Lower your long-term energy bills

These clear-glass windows are often sold under the term “builder-grade” or “contractor-grade”—and they simply don’t hold up in our Southern climate.

3. Why Wincore’s 5400 and 7700 Series Are Worth the Upgrade

At Southwest Window & Door, every window we install from Wincore’s 5400 and 7700 series includes Low-E Argon insulated glass—standard. These aren’t "upgrade" options; they’re part of what we believe every homeowner in Little Rock deserves for quality and performance.

The benefits include:

• Energy savings year-round

• Greater indoor comfort

• Better UV protection

• Enhanced condensation resistance

• Improved noise reduction

Want to go beyond even that? We offer additional performance glass packages for homes that need more solar control, higher insulation values, or added security features.

4. Perfect for the Arkansas Climate

Little Rock and the Central Arkansas region experience hot, humid summers and cold, damp winters. That means your windows have to work both ways—keeping heat out and warmth in.

Low-E Argon windows are the smart, long-term solution for homeowners who want:

• Consistent indoor temperatures

• Lower heating and cooling costs

• Reduced strain on their HVAC system

5. Make the Smart Choice—Don't Settle for Cheap Glass

It’s tempting to go with the lowest bid when comparing window replacement quotes in Arkansas—but be sure to compare what you’re actually getting. A cheaper window that lacks Low-E Argon can cost you more in the long run through higher energy bills, reduced comfort, and premature window failure.
