Serving Homeowners Throughout Utah County and the Wasatch Front

If you live in Lehi, American Fork, Pleasant Grove, Highland, Alpine, Draper, Sandy, Draper, Salt Lake City, Eagle Mountain, Saratoga Springs, Orem, Provo, or one of the surrounding communities, you already know how much Utah’s weather can change throughout the year.

At Utah Valley Window & Door, we work with homeowners throughout Utah County, Salt Lake County, and the Wasatch Front to replace aging and inefficient windows with options better suited for our hot summers, cold winters, and strong Utah sun. Because every home is different, we’ll help you compare window and glass options based on your home’s exposure, comfort concerns, and budget—not simply recommend the same window package for everyone.

Why Energy-Efficient Windows Matter in Utah

Utah’s climate creates challenges in both winter and summer. During colder months, homeowners want to reduce heat loss through their windows. During summer, the goal changes: windows need to help limit unwanted solar heat while still providing natural light.

Homes in Utah that are located with significant west- or south-facing glass can be particularly affected by afternoon sun. At the same time, poorly performing older windows may contribute to drafts and uncomfortable areas during the winter.

That’s why selecting replacement windows based on whole-window performance is more useful than focusing on a single feature.

Understanding U-Factor

One of the most useful numbers when comparing replacement windows is the U-Factor.

U-Factor measures how readily heat transfers through the complete window assembly. In general, a lower U-Factor indicates better insulating performance.

For example, many high-performance replacement window configurations offered by Utah Valley Window and Door can achieve U-Factors in approximately the 0.24–0.26 range, depending on the window and glass package selected.

When comparing estimates, make sure you’re comparing the performance of the entire window, rather than only the center-of-glass value.

What Is SHGC?

Solar Heat Gain Coefficient (SHGC) measures how much solar heat passes through a window.

This can be especially important in Utah because of our abundant sunshine and intense summer sun.

A lower SHGC generally means the window allows less solar heat into the home. Depending on the configuration, some of the high-performance glass packages we offer have SHGC ratings around 0.22–0.24.

However, the lowest number isn’t automatically the right choice for every window in every home. Orientation, shade, window size, and the homeowner’s priorities should also be considered.

Low-E Glass and Utah’s Strong Sun

Low-E, or low-emissivity glass, uses specialized coatings designed to improve the thermal performance of the glass.

New replacement windows with Low-E packages can help control heat transfer while still allowing natural light into the home. Different coatings and glass configurations can provide different performance characteristics.

For Utah homes with substantial sun exposure, choosing the appropriate Low-E package can be particularly important.

At Utah Valley Window & Door we recommend considering the home’s orientation, is it west or east? What kind of windows are your home’s existing windows, how much glass are they double pane or triple pane? The amount of exposure to sunlight.

Double-Pane vs. Triple-Pane Windows

Both double-pane and triple-pane replacement windows can provide good energy performance when properly configured and installed.

Double-pane windows are a popular choice because they can provide a strong balance between performance and cost. Modern insulated double-pane glass with the appropriate Low-E coating can perform substantially better than many older windows.

Triple-pane windows add another pane of glass and another insulating space. Depending on the window system and glass configuration, this can further improve insulating performance.

The right choice depends on your home, budget, comfort goals, and the specific performance numbers of the windows you’re considering.

Don’t Forget the Window Frame

Glass receives a lot of attention when homeowners shop for energy-efficient windows, but the frame is also part of the window’s thermal performance. New replacement windows come in Vinyl and Fiberglass frames and at times homeowners looking to preserve their homes antiquity like to replace their windows with wood frames.

Frame design, internal chambers, reinforcement, weatherstripping, seals, and insulating components can all influence how the complete window performs.

That’s another reason we recommend comparing whole-window ratings rather than choosing a window based solely on a particular type of glass. Not all Utah homes are created the same, architecture is also a consideration!

Installation Matters

Even a high-performance window cannot perform as intended if it isn’t installed correctly.

The replacement window needs to fit the opening properly and be correctly secured, insulated, sealed, and finished. Gaps or poor sealing around the window can undermine some of the benefits of purchasing a better-performing product.

At Utah Valley Window and Door, our replacement windows are installed by our own installation team. This allows us to maintain control of the project from measurement through installation.

Should Every Window in Your House Have the Same Glass?

Homeowners looking to replace their windows in Utah do have a choice! Choose bedroom windows with triple pane if close to a noisy area. Double pane for kitchen windows generally is fine. A large west-facing picture window may experience considerably different solar exposure than a smaller window on the north side of the same house. Of course one of our sales representatives that is actually in your home and the homeowners themselves always know what the amount of sunlight or noise they need to block.

For larger or whole-house window replacement projects, it can make sense to consider how different areas of the home are used and how much direct sunlight each elevation receives.

Choosing Energy-Efficient Replacement Windows in Utah

When comparing replacement windows, homeowners should consider:

• Whole-window U-Factor
• Solar Heat Gain Coefficient (SHGC)
• Low-E glass configuration
• Double-pane versus triple-pane glass
• Frame construction
• Window orientation and sun exposure
• Installation quality
• Warranty coverage
• Overall cost and long-term value

No single specification tells the entire story. A properly selected and professionally installed window combines these factors to provide the performance appropriate for the home.
