Gas-Filled Glass vs Impact Resistant Glass: Which Is Better?

September 29, 2024

Key Takeaways

Gas-filled glass improves thermal insulation and energy efficiency.
Impact-resistant glass has enhanced safety and protection against break-ins and extreme weather.
Argon, krypton, and xenon are the most commonly used gases in gas-filled glass due to their insulation properties.
Impact-resistant glass typically combines laminated glass with a heavy-duty frame.
At Panda, we’ll help you choose between gas-filled and impact-resistant glass depending on your location, climate, and security needs.

What is Gas-Filled Glass

Gas-filled glass units are double or triple-pane windows and doors where the space between the panes is filled with a non-toxic, colorless, and odorless gas, such as argon, krypton, or xenon.

These gasses are denser than air, which provides better insulation and increases the window’s thermal efficiency.

So, how does gas-filled glass work? It’s pretty simple. The gas acts as an insulator, slowing down the transfer of heat through the window.

This means that in the winter, the heat stays inside, and in the summer, the heat stays outside, making your home more comfortable year-round.

Advantages of Gas-Filled Glass

One of the main advantages of gas-filled glass is its ability to maintain consistent temperatures in your home.

This enhances comfort and also reduces the burden on your heating and cooling systems, potentially lowering your energy bills. Because this glass can reduce the amount of ultraviolet and infrared light that enters your home, it can help prevent fading of your interior furnishings.

Disadvantages of Gas-Filled Glass

Over time, the gas can slowly leak out of the window, diminishing its insulative properties. Also, these windows can be more expensive upfront than traditional windows.

This particular glass type may also not be necessary in climates that do not experience extreme temperatures.

What is Impact Resistant Glass

Impact-resistant glass is designed to withstand severe weather conditions and forced entry attempts. It is constructed with a tough interlayer sandwiched between two layers of glass. When struck, the glass may crack, but the interlayer keeps the overall pane intact, preventing shards from flying and deterring potential intruders.

What makes impact-resistant glass so strong? The secret lies in the interlayer, typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This layer holds the glass together under stress, providing an additional barrier against the elements and unexpected impacts (image courtesy of Burglar Proof Windows).

Advantages of Impact-Resistant Glass

Increased safety from storms and potential break-ins.
Sound-dampening properties for a quieter indoor environment.
UV protection, like many impact-resistant windows, also includes low-E coatings.
Provides enhanced safety for your home or business by resisting shattering upon impact

Disadvantages of Impact-Resistant Glass

Impact-resistant glass is more expensive than regular or annealed glass and can be overkill in regions that don’t experience severe weather. Additionally, if the glass does sustain damage, the entire pane usually needs to be replaced, which can be costly.

Gas-Filled Glass vs Impact-Resistant Glass

Energy Efficiency

Gas-filled glass has a better energy-efficient performance than impact-resistant glass. Its insulating properties help to keep your home at a consistent temperature, which can reduce the load on your HVAC system. Impact-resistant glass, while it can also be efficient, primarily focuses on safety rather than insulation.

Cost Considerations

Gas-filled glass tends to be more affordable than impact-resistant ones. However, you must weigh the potential energy savings over time against the initial investment.

Impact-resistant glass, while pricier, can save you money on repairs and replacements after severe weather events or attempted break-ins.

Installation and Maintenance

Both gas-filled and impact-resistant glasses require professional installation to make sure they function as intended. Maintenance for gas-filled glass is minimal, although you’ll want to watch for signs of seal failure, such as condensation between panes. Impact-resistant glass is also low maintenance, but you’ll need to inspect it after any event that could cause damage.

Regular cleaning and occasional inspections are generally all that’s needed to keep both types of glass in top shape. If you notice a breach in the seal of a gas-filled window or a crack in an impact-resistant door, it’s important to address it promptly to maintain their respective benefits.

For example, after a major storm, it’s wise to check your impact-resistant windows and doors for any signs of damage. Even if they appear intact, a professional can assess if the interlayer has been compromised, which could affect the performance.

Aesthetic and Practical Considerations

Both gas-filled and impact-resistant glass are available in a variety of styles to suit your home’s design. Your location and the typical weather patterns are the most important factors – for instance, in hurricane-prone areas, impact-resistant glass is a practical necessity, whereas in colder climates, gas-filled glass might be the better option for thermal insulation.

Ideal Uses for Each Glass Type

Best Situations for Gas-Filled Glass

Gas-filled glass is best suited for areas where energy efficiency is a top concern. If you’re looking to reduce your heating and cooling costs, these windows are a smart choice.

They are particularly beneficial in regions with significant temperature swings, as they can help maintain a comfortable indoor climate.

Best Situations for Impact-Resistant Glass

Impact-resistant glass is ideal for areas prone to severe weather, such as coastal regions that experience hurricanes. It’s also a good choice for ground-floor windows in urban areas where security might be a concern.

Anywhere that safety from breakage is a priority, impact-resistant glass is the way to go.
