1. Low-E Glass and Argon Gas for Better Insulation
Modern windows use two advanced technologies – Low-E glass coatings and argon gas fills – to improve energy efficiency. Together, they help homeowners in Frisco maintain a comfortable indoor environment while cutting down on energy costs. Here’s how these features work for energy savings and money.
Low-E (Low-Emissivity) glass has an ultra-thin coating, about 500 times thinner than a strand of hair [3]. This coating lets visible light pass through but blocks most ultraviolet (UV) and infrared rays. For comparison, standard glass has an emissivity of 0.84, while Cardinal Glass 366 achieves a much lower rating of 0.02 [3]. This technology can reduce heat loss through windows by up to 50% [4], which is significant since windows and doors account for roughly 30% of a home’s total heat loss [4].
Argon gas fills provide an additional layer of insulation between window panes. Argon is 5½ times denser than regular air [9], creating a stronger thermal barrier. When combined with Low-E coatings, these windows deliver impressive results:
| Feature | Benefit | Performance Impact |
|---|---|---|
| Low-E Coating | Filters UV and infrared light | Cuts heat transfer by up to 50% [4] |
| Argon Gas Fill | Improves insulation | Lasts effectively for 20+ years [5] |
| Combined Features | Maximum energy efficiency | Lowers energy bills by 15–30% [8] |
For Frisco’s climate, experts recommend windows that include both Low-E coatings and argon gas fills. While the upfront cost is higher, these windows retain their efficiency for over 20 years [5], with minimal argon leakage of about 1% annually [6]. In fact, modern Low-E windows with argon gas can cut energy use by up to 40% [7]. This makes them a smart investment for homeowners aiming to reduce utility expenses and maintain a comfortable home all year long.
2. Double Windows Stop Heat Loss
Double pane are a smart choice for reducing energy costs, thanks to their excellent insulation capabilities. These windows use a layered design combined with insulating gases to create a barrier that minimizes heat loss.
By combining multiple glass layers with insulating gaps, these windows improve energy efficiency significantly. Double-pane windows typically offer R-values of 3–3.8, reducing heat loss by 30–40%.
| Window Type | Insulation (R-value) | Energy Reflection | Heat Loss Reduction |
|---|---|---|---|
| Double-Pane | 3.0 – 3.8 | 90% | 30–40% |
The insulating gap between the panes is filled with gases like argon, which slow down thermal transfer. This gas enhances insulation; for instance, argon can improve R-values by about 30% compared to air.
“Today’s double pane insulated windows that use argon gas, and low–e coated glass tinted specifically for our climate area, are a great window option from an energy saving perspective, and have had a long history of good opinions in occupant comfort” [14].
This design can lower heating and cooling costs by as much as 15% annually [13], which is especially impactful since windows account for up to 50% of a home’s temperature regulation needs [12].
3. Better Natural Light Cuts Electric Usage
Modern windows go beyond insulation – they’re designed to bring in more natural light while keeping energy use in check. By allowing more daylight into your home, these windows reduce the need for artificial lighting, saving energy in the process.
One key feature is spectrally selective coatings, which allow full daylight to pass through while filtering out 40–70% of heat [16]. This makes them especially suited for sunny climates like Frisco.
Here’s how modern window designs improve daylight exposure and energy savings:
| Feature | Benefit | Energy Impact |
|---|---|---|
| Slimline Frames | Larger glass area | Brings in more natural light, reducing artificial lighting |
| High VT Rating | Increased light transmission | Lowers reliance on electric lights |
| Spectrally Selective Coating | Manages heat while letting in light | Reduces heat by 40–70% without dimming daylight |
According to EnergyStar, these windows can save homeowners between $71 and $501 annually on energy bills [2].
In Frisco, opting for windows with a higher Light-to-Solar Gain (LSG) ratio ensures your home stays bright without overheating, improving energy efficiency [17].
