SmartSun™ Glass: What Is It, and Why Get It?

How are your windows looking? Like most exterior home components, they are exposed to the harsh and changing weather everyday of the year. It won’t surprise you then to notice a significant amount of wear and tear over time. Issues, such as cracked and rotten frames, broken glass and inoperable hardware, may be present, all of which will prompt a better and longer-lasting solution: window replacement.

This home improvement project, however, will require some careful planning. After all, you’ll want to get the most out of this investment. That’s why you should cover all the bases. These include reading up on the essential components making up your replacement windows, specifically the glass packages included with them. The type of glass used by your new units can actually make a huge difference to your home’s indoor comfort and overall energy efficiency.

Types of Window Glass

There are many types of window glass available today, including:

  • Insulated glass. This option uses two or more panes separated by a spacer. The space between these panes are filled with gas for better insulating value.
  • Heat-absorbing glass. This kind of glass comes with tints that absorb a large amount of incoming solar heat while also reducing glare.
  • Spectrally selective glass. This option filters out a significant portion of the sun’s heat coming through the window while still allowing the full amount of light.
  • Low-emissivity (Low-E) glass. This excellent option features microscopically thin, invisible, metallic oxide layer applied directly to the glass’s surface. It lowers the window’s U-factor, which measures the unit’s insulating properties and resistance to heat flow. The lower the U-factor, the more energy-efficient the window.

So, which window glass is best for you?

You might want to consider low-E glass because it helps improve indoor comfort while reducing energy loss much better than other options. What’s more is that the window glass can be customized according to your solar heat gain needs. Some window manufacturers even built upon the glass’s inherent features, allowing for greater, more reliable energy performance. A prime example of this is the High-Performance™ Low-E4® SmartSun™ Glass offered exclusively by Renewal by Andersen®.

What Is High-Performance™ Low-E4® SmartSun™ Glass?

As one of the most energy-efficient window glass options available today, High-Performance Low-E4 SmartSun Glass offered by Renewal by Andersen builds on the best features of dual-pane glass to effectively reduce your home’s heating and cooling bills. By utilizing an advanced coating technology, it is 49% more efficient in winter and 70% more efficient in summer compared to standard dual-pane glass.

Why Invest in This Glass Option?

High-Performance Low-E4 SmartSun Glass has the highest efficiency rating in cool weather. It is an exceptional choice in hot climates where solar heat gain can lead to increased cooling bills. This advanced glass is notable for reflecting heat.

During summer, it reduces the amount of heat transferring into your home via the windows. This results in cooler, more comfortable living spaces that don’t rely as much on air conditioning. Meanwhile, in the colder months, High-Performance Low-E4 SmartSun Glass effectively traps heating energy inside your home, allowing for warmer, cozier rooms. Overall, this glass option is proven to improve indoor comfort in any season minus the high energy bills.

Like window glass with spectrally selective coatings, High-Performance Low-E4 SmartSun Glass lets in a considerable amount of natural light into your home while blocking the sun’s heat and glare. It also keeps your home’s interior protected from sun damage by blocking up to 95% of harmful ultraviolet (UV) rays. This ensures your walls, flooring and furniture remain vibrant and intact for years by limiting fading and deterioration because of the sun.

But, how do you keep your High-Performance Low-E4 SmartSun Glass looking sparkling clean? Fortunately, it comes with an innovative coating that stops water spots, allowing for easier, more stress-free cleaning. In addition, the glass option significantly reduces noise pollution in your home by way of its optimized spacer and insulating gas fill.

Windows with High-Performance Low-E® SmartSun Glass have both the ENERGY STAR®and National Fenestration Rating Council (NFRC) labels. This means they have met strict energy performance standards, scored with ratings for U-Factor, Solar Heat Gain Coefficient (SHGC) and Visible Transmittance. They are also qualified for all climate zones in the United States and helps contribute to a better environment by reducing energy consumption and carbon footprints.

How Do You Make the Most of Your New Windows?

Add an extra layer of protection to your investment by choosing windows with High-Performance Low-E4 SmartSun Glass. They are backed by an exclusive 20-year warranty covering manufacturing, material and workmanship defects.  Just make sure you work only with a Renewal by Andersen window expert for their installation.

Windows are the sum of their parts. As the biggest component in a unit, glass plays a major role in how your new windows will perform. By taking into account the glass package included with your replacement windows, you’ll be able to harness the technological advancements incorporated into their design, which allow for greater indoor comfort and lower energy costs.
