Impact-Resistant Glass vs Double-Glazed Glass: Which Is Better?

Key Takeaways

• Impact-resistant glass offers superior protection against extreme weather and break-ins.
• Double-glazed glass is excellent for energy efficiency and noise reduction.
• Impact-resistant glass costs more upfront but leads to savings on energy bills and insurance premiums.
• Double-glazed glass is relatively affordable and energy-efficient.
• Panda Windows & Doors offers custom impact-resistant and double-glazed glass.

What is Impact-Resistant Glass?

Impact-resistant glass is designed to withstand high-impact forces without shattering. This type of glass is commonly used in areas prone to severe weather conditions and where security is a top priority.

Impact-resistant glass has multiple layers, including a tough interlayer, usually made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). These layers are laminated together to create a strong barrier that can absorb and distribute the force of impact.

Advantages of Impact-Resistant Glass

Increased Security

Impact-resistant glass is much harder to break than standard glass, deterring would-be burglars.

Weather Protection

This type of glass is designed to withstand strong winds, rain, hail, and the impact of flying debris.

Noise Reduction

Impact-resistant glass has a laminated interlayer that acts as a sound barrier. This layer dampens vibrations from external noise, such as traffic or airplanes.

Disadvantages of Impact-Resistant Glass

Cost

The initial cost of impact-resistant glass is higher than standard glass. This is due in part, to the specialized materials and manufacturing processes required to produce glass that can withstand impact.

However, the long-term benefits and potential savings on energy bills and insurance premiums can make it a worthwhile investment.

Style Limitations

While impact-resistant glass is available in various styles, it may not have as many design options as standard glass. This could limit your choices when it comes to customizing the look of your windows and doors.

What is Double-Glazed Glass?

Double-glazed glass, also known as insulated glass, consists of two panes of glass separated by a spacer and sealed to create an insulating air space. This design significantly improves energy efficiency and noise reduction.

The manufacturing process involves assembling two glass panes with a spacer in between, which is then sealed around the edges. The spacer can be filled with air or an inert gas like argon to enhance its insulating properties.

Advantages of Double-Glazed Glass

Energy Efficiency

Double-glazed glass has trapped air or argon between two panes of glass, reducing heat loss and improving energy efficiency compared to single-pane windows.

Improved Comfort

Double glazing reduces cold spots and drafts, helping to maintain a more consistent and comfortable indoor temperature.

Condensation Control

Double glazing reduces the likelihood of condensation forming on windows and in turn, prevents mold and mildew.

Premium quality multi-layered glazing options such as double-glazing can prevent condensation build-up and stop mold from forming.

Disadvantages of Double-Glazed Glass

Cost

Although double-glazed glass is more affordable than impact-resistant glass, it still requires significant investment. The cost can vary based on the size of the window, the type of gas used between the panes, and the quality of materials.

The initial cost of double-glazed windows may be offset by long-term savings on energy bills.

Maintenance

Double-glazed windows require periodic maintenance to retain their insulating properties. This includes checking the seals as any breach can lead to a loss of insulation.

In addition, cleaning double-glazed windows can be more challenging due to the two layers of glass, especially if condensation forms between the panes.

Ideal Uses for Each Glass Type

Impact-Resistant Glass

• Coastal and Storm-Prone Areas: Homes located in coastal, storm-prone areas need impact-resistant glass. Hurricanes and typhoons can send debris flying at high speeds and impact-resistant glass is designed to withstand such damage.
• High Security: The tough, laminated layers of this type of glass make it difficult for intruders to break through and impact-resistant glass windows are a strong deterrent against break-ins. 
• Busy and Noisy Locations: Impact-resistant glass dampens external sounds, creating a quieter and more peaceful indoor environment. 

Double-Glazed Glass

• Cold Climates: The insulating layer between panes of double-glazed window glass prevents some heat loss, thereby reducing heating costs. By maintaining a consistent indoor temperature, double-glazed glass can make your home more comfortable during the colder months.
• Energy-Efficient Homes: For those focused on energy efficiency, double-glazed glass significantly reduces heat transfer, so your heating and cooling systems aren’t overworked.
• Urban Dwellings: Double-glazed glass is ideal for homes located in urban areas where noise pollution is a concern. The insulating layer not only helps with temperature regulation but also acts as a sound barrier, reducing the amount of external noise that enters your home.
