SHGC and Why Should You Care in Utah
What is SHGC?
At Utah Valley Window & Door, we prioritize energy efficiency and comfort in your home. The Solar Heat-Gain Coefficient (SHGC) is a crucial factor to consider when selecting windows, doors, or skylights. It measures the portion of solar radiation that passes through, represented by a number between 0 and 1.
Selecting the Right SHGC for Your Climate
- Lower SHGC (e.g., less than 0.30): This is ideal for hot climates or summer months, as it minimizes heat gain, helping keep indoor spaces cooler and reducing reliance on air conditioning.
- Higher SHGC: Suitable for colder climates, as it permits more solar heat to enter, providing passive heating and reducing the need for additional heating sources.
By choosing the appropriate SHGC for your location, you can enhance energy efficiency and maintain a comfortable indoor environment throughout the year.
If you live along the Wasatch Front—from Salt Lake City to Utah Valley—you already know how extreme our climate can be. Hot, dry summers. Cold, snowy winters. And major temperature swings in between.
That’s exactly why high-performance insulated glass has become one of the most important upgrades you can make to your home.
At Utah Valley Window & Door, we see it every day: homeowners dealing with rooms that are too hot in the summer, too cold in the winter, and energy bills that keep climbing.
Let’s break down what high-performance glass actually is—and why it makes such a big difference in heat rejection, comfort, and efficiency for homes in Utah.—
What Is an Insulated Glass Unit?
New replacement windows aren’t just “glass.” They’re built as insulated glass units (IGUs)—a system designed to control heat transfer and improve energy performance.
A high-performance glass package typically includes:
- Double or triple panes of glass
- Argon gas fills between panes
- Low-E (low emissivity) coatings
- Advanced spacer systems
Since windows are mostly glass, the performance of that glass directly impacts your home’s comfort and energy efficiency!
How High-Performance Glass Rejects Heat in Utah Summers
If you’ve ever stood next to a window in July in Lehi, Sandy, or Draper, you’ve felt it—that intense radiant heat coming through the glass.
This is where Low-E coatings make a major difference.
What Low-E Glass Does
- Reflects solar heat away from your home
- Reduces indoor heat buildup
- Keeps interior temperatures more consistent
Think of Low-E as a built-in heat shield. Instead of letting the sun bake your home, it reflects much of that energy back outside—critical in Utah’s high-elevation sun.—
How It Keeps Your Home Warm During Utah Winters
That same technology works in reverse when temperatures drop.
High-performance insulated glass helps:
- Reflect indoor heat back into your home
- Reduce cold drafts near windows
- Keep interior glass surfaces warmer
This is especially important in cities like Provo, Orem, and Salt Lake City, where winter temperatures can drop quickly. Instead of losing heat through your windows, you keep it inside where it belongs.
Why Triple-Pane Glass Makes a Big Difference
One of the biggest advancements in window technology is triple-pane glass.
Compared to standard double-pane windows, triple-pane systems:
- Add an extra layer of insulation
- Include multiple Low-E coatings
- Improve both heat rejection and heat retention
For Utah homeowners, that means better year-round comfort and less strain on your heating and cooling systems.—
The Role of Argon Gas
Between the panes of glass is typically argon gas, which plays a key role in insulation.
Argon gas:
- Is denser than air
- Slows down heat transfer
- Improves overall energy efficiency
It’s an invisible upgrade—but one that makes a noticeable difference in performance.—
Real Benefits for Utah Homeowners
When all these technologies work together, you get a window system designed specifically for Utah’s climate.
What You May Notice Right Away
- Cooler rooms during peak summer heat
- Less cold air near windows in winter
- More consistent indoor temperatures
- Reduced glare and UV exposure
Long-Term Benefits
- Lower energy bills
- Improved home value
- Less wear on HVAC systems
- Better overall comfort year-round
Why This Matters on the Wasatch Front
Homes in Utah Valley and Salt Lake County face unique environmental challenges:
- High elevation means stronger UV exposure
- Large temperature swings between day and night
- Hot summers combined with cold winters
This makes choosing the right glass package critical. A basic window may look fine—but without high-performance glass, it won’t deliver the comfort your home needs.—
Choosing the Right Glass for Your Home
Not all insulated glass systems are the same. The right setup depends on:
- Your home’s orientation (sun exposure)
- Your comfort goals
- Your budget
- Desired energy efficiency levels
At Utah Valley Window & Door, we help homeowners throughout the Wasatch Front choose the right combination of glass technology for their specific needs.—
