Quick Answer:
FixHomeGlass restores home energy efficiency by replacing compromised window units with Cardinal Glass featuring patented XL Edge stainless steel spacer technology. This advanced design maintains a moisture-tight seal that retains insulating argon gas for over 20 years without requiring a full window frame replacement.
The primary reason homeowners in the Chicago suburbs buy high performance windows is for the invisible protection of the argon gas that fills the space between the two glass panes. Argon is much denser than normal air therefore it provides a superior thermal barrier to the outside elements. The argon gas helps keep your home warm during the cold, winter months and also dampens outside sound.
The longevity of a window’s energy efficiency is entirely dependent upon how well it can contain this gas. At FixHomeGlass, we would like to share the “secrets” of how XL Edge Technology provides maximum retention of argon for decades.
The Difficulty: The Great Escape
In many common two pane windows, as time goes by, the argon gas leaks out through the broken seal and is replaced by warm, moist air. When this gas is no longer present, then the insulating ability of the window has been compromised and will no longer function properly. You may notice signs of gas loss:- Foggy or Cloudy Glass: One of the first things you will see is fog or moisture between the two panes of glass.
- Increased Noise Level: Outside sounds from traffic, trains, or airplanes becoming noticeably louder over time.
- Permanent Deposits: Another sign is the buildup of white mineral ring “calcium” deposits on the inside of the window where the seal has been broken for an extended period.
- Rising Costs: Because there is no longer a thermal barrier in the two pane window, you will see an increase in your heating and cooling costs.
The Secret: XL Edge Technology
To prevent gas loss, FixHomeGlass exclusively uses units from Cardinal Glass Industries featuring patented XL Edge spacer technology. This design is specifically engineered to create a permanent, moisture-tight closure.- Stainless Steel Construction: Unlike older aluminum spacers which are highly conductive, the XL Edge is manufactured with stainless steel.
- Thermal Efficiency: With a lower thermal conductivity, stainless steel will maintain the temperature of the perimeter edge of the glass for longer and therefore will avoid the unit reaching the “dew point”.
- Double Silicone Sealant: The use of two silicone sealants on the perimeter edge will keep the failure rate at just 0.20% over 20 years.
- Argon Retention: The frame construction and spacer provides a moisture-tight seal to protect and hold the argon gas.
- Polymer-Free Design: Our units eliminate the risk of chemical fogging inside the unit, ensuring the gas stays pure and the glass stays clear for the life of the warranty.
Financial Benefits Over Time
A window that uses superior argon retention is an investment that will eventually pay for itself through the reduced monthly utility bills associated with the reduced workload on your HVAC system. When the argon remains sealed, it prevents your HVAC from needing to work as hard to keep your home at a comfortable temperature. Additionally, UV rays can damage many of your home’s materials, including expensive hardwood floors and furniture, but with argon gas retained in the glass, you can provide some protection from the sun’s rays. Lastly, since these units are built to last, you can avoid the hidden costs of delaying repairs or repeatedly replacing the same glass unit every few years.The Hidden Costs of Deferred Maintenance
When ignoring failed seals and/or cracked glass prior to a listing will lead to significantly higher-priced repairs at a later date. When water accumulates in the window frame due to a failed seal, it could lead to underlying structural issues such as mold or decay of the wood. Many professional home inspectors will mark windows that have foggy appearance as a significant deficiency. By proactively replacing the insulated glass unit (IGU) via FixHomeGlass, you will close the door on this negotiating obstacle before it becomes an issue.Why Glass-Only Restoration Wins
The most energy efficient and cost-effective way to prepare a property for sale is to just replace the glass rather than the entire window. Our glass-only replacement process is also the quickest, cleanest and least intrusive way to add value to your home as compared to a full renovation. We only purchase our glass from a well-known US manufacturer, Cardinal Glass Industries, giving you the same superior thermal insulation typically found in luxury new home construction. This allows you to list your property with modern high-performance glazing while maintaining the original architectural details of the wood frame elements.The FixHomeGlass Restoration Guarantee
Here at FixHomeGlass, we feel that you shouldn’t need to discard your window system if the argon gas has escaped. Our company specializes in a glass-only surgical method of replacement. Instead of creating a mess by having a full-frame teardown performed, we can precision install a brand new argon filled Insulated Glass Unit (IGU) right into your existing wooden, vinyl or aluminum frames. This process is the quickest and least invasive way to restore the thermal “wall of air” around your home as protection against the elements in Chicago.- 20-Year Warranty: All of the glass we install is manufactured by Cardinal Glass Industries. Each piece of glass has a 20-year warranty on its thermal seal
- Expert Support: All services are performed by staff who have been in the industry for over 10 years.
- Fixed Pricing: After our free consultation, you will only be charged the individual price we provided for completing the project and there are absolutely no hidden fees at closing.

Frequently asked questions
Why does argon gas escape from standard windows?
Over time, standard window seals break down due to thermal stress and inferior materials. Once the seal fails, the dense argon gas escapes and is replaced by moist air, causing reduced thermal insulation, foggy glass, higher noise levels, and mineral deposits.
How does XL Edge Technology prevent gas loss for 20+ years?
XL Edge Technology utilizes a low-conductivity stainless steel spacer combined with a double silicone sealant and a polymer-free design. This structure creates a permanent, moisture-tight barrier that resists thermal transfer and maintains a 99.8% seal reliability rate over 20 years.
What are the financial benefits of retaining argon gas in windows?
Maintaining argon gas keeps your home insulated, reducing the workload on your HVAC system and lowering monthly utility bills. It also protects interior flooring and furniture from UV damage and eliminates the recurring cost of frequent glass replacements.
