Double-Glazed Glass vs Spandrel Glass: Which Is Better?
November 5, 2024
Key Takeaways
- Double-glazed glass consists of two panes of glass with a space in between, offering excellent insulation and noise reduction.
- Spandrel glass is opaque and used to cover structural elements, providing a sleek and modern appearance.
- Double-glazed glass is ideal for areas where energy efficiency and noise reduction are priorities.
- Spandrel glass is best suited for non-vision areas, enhancing building aesthetics without compromising on energy efficiency.
- Panda Windows & Doors offers customized solutions for both glass types.
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 together. This space is filled with an inert gas like argon to improve its insulating properties – with the design improving thermal performance and also reducing noise, making it a popular choice for both residential and commercial buildings.
Besides the basic construction, the type of glass used can vary. Low-E coatings can be applied to further enhance energy efficiency by reflecting heat back into the room during winter and keeping it out during summer.

Energy Efficiency Benefits
By reducing heat transfer, it keeps homes warmer in winter and cooler in summer, which can lead to substantial savings on energy bills. According to some studies, double-glazed windows can reduce energy consumption by up to 30% compared to single-pane windows.
Noise Reduction Features
Double-glazed glass also excels in noise reduction, making it an excellent choice for properties located in busy or noisy environments. The space between the glass panes acts as a buffer, dampening sound vibrations and providing a quieter indoor environment. This feature is particularly beneficial in urban settings where noise pollution is a concern.
Durability and Weather Resistance
Another advantage of double-glazed glass is its durability. The sealed design protects against the elements, reducing the risk of weather-related damage. It’s also more resistant to breakage than single-pane glass, offering an added layer of security.
Advantages of Double-Glazed Glass
- Excellent thermal insulation reduces energy costs.
- Effective noise reduction for a quieter indoor environment.
- Increased security due to its durable design.
- Potential to add Low-E coatings for enhanced energy efficiency.
Disadvantages of Double-Glazed Glass
Despite its many benefits, double-glazed glass does have some drawbacks. It can be more expensive upfront compared to single-pane glass, and the installation process is more complex. Also, if the seal between the panes is compromised, it can lead to condensation and reduced efficiency.
What is Spandrel Glass?
Spandrel glass is a type of opaque glass used in building facades to conceal structural elements and provide a uniform appearance. Unlike double-glazed glass, spandrel glass is not meant to be seen through. Instead, it offers a sleek and modern look while maintaining energy efficiency.
Variety of Design Options
Spandrel glass is highly versatile in terms of design. It can be customized in a variety of colors and finishes to match the aesthetic requirements of any building, which makes it a popular choice for architects who wish to achieve a seamless and modern appearance for a building’s facade.
As well as a choice of color options, spandrel glass can be treated with different coatings to enhance its performance. For instance, ceramic frits can be applied to increase opacity and provide additional UV protection. This flexibility allows architects to use spandrel glass creatively, integrating it into various architectural styles and designs.
Advantages of Spandrel Glass
Spandrel glass offers several advantages that make it an appealing choice for many architectural projects.
Firstly, its ability to conceal structural elements while maintaining a sleek appearance is invaluable for modern building designs. This feature allows for a clean and uninterrupted facade, enhancing the building’s overall aesthetic.
Spandrel glass also contributes to energy efficiency by insulating non-vision areas of a building. It helps reduce heat transfer, which can lead to lower energy costs. Spandrel glass is also durable and resistant to weathering, ensuring long-lasting performance.
Disadvantages of Spandrel Glass
One of the main drawbacks is that it is not transparent, meaning it cannot be used in areas where natural light or visibility is desired – which limits its application to non-vision areas of a building.
The cost of spandrel glass can be higher than traditional glass due to its specialized coatings and treatments. This can be a consideration for projects with tight budgets. The installation of spandrel glass requires precision to ensure a seamless appearance, which may increase labor costs.
Spandrel glass is ideal for commercial buildings where areas need to be hidden for a sleek and cohesive look.
