Key Takeaways

  • Obscured glass allows light to pass through but limits visibility, creating a sense of privacy.
  • Spandrel glass is opaque and used to conceal the structural elements between floors of buildings.
  • Obscured glass is ideal for spaces like bathrooms and offices that need both light and visibility, while spandrel glass is primarily used in commercial buildings for aesthetic and functional purposes.
  • From energy efficiency to costs, both glass types have their benefits. A choice between them depends on our specific needs and preferences.
  • At Panda Windows & Doors, we deliver custom window and door solutions using high-quality glass materials like obscured and spandrel glass.

What is Obscured Glass?

Obscured glass is a type of translucent glass made through various methods like sandblasting, acid etching, or applying a frosted film. The result is a glass that limits visibility without completely blocking out light.

What is Spandrel Glass?

Spandrel glass is a type of opaque glass used primarily in commercial buildings to conceal structural elements such as columns, beams, and floor slabs. Unlike obscured glass, spandrel glass does not allow light to pass through and is used for both aesthetic and functional purposes.

Pros and Cons

Pros of Obscured Glass

Obscured glass allows for both privacy and some natural light. It lets in just enough sunlight for some visibility but diffuses the rest, increasing privacy and security, reducing glare, and blocking harmful UV rays.

With its wide variety of styles and patterns, obscured glass also has enough design flexibility to fit any architectural style.

Cons of Obscured Glass

Obscured glass is more expensive than regular clear glass due to the additional processing required to create the frosted or textured effect - and the textured surface of some types of obscured glass can also be more challenging to clean and maintain, as dirt and grime can accumulate in the crevices.

Pros of Spandrel Glass

Spandrel glass creates a clean and streamlined appearance for building facades by concealing structural elements and mechanical equipment. This type of glass is highly durable and can withstand significant thermal stress, making it suitable for various climates and environmental conditions.

On top of that, it’s available in a wide range of colors and finishes, allowing you to achieve any design aesthetic you wish for your property.

Cons of Spandrel Glass

Spandrel glass can be more expensive than other types of glass due to the specialized coatings and treatments required to achieve its opacity. Because it’s often used in large panels, it is also more challenging and costly to install and replace compared to smaller glass panes.

Obscured Glass vs Spandrel Glass

Energy Efficiency

Obscured glass provides good thermal insulation, especially when used in double-glazed or triple-glazed units. This helps to reduce heat loss in the winter and keep interiors cool in the summer, leading to lower energy bills.

On the other hand, spandrel glass is typically used in non-vision areas of a building, so its energy efficiency is less of a concern. However, it can still contribute to the overall thermal performance of a building when used in conjunction with other energy-efficient glazing solutions.

Costs

The cost of obscured and spandrel glass changes significantly depending on the specific type, size, and treatment required. Obscured glass can be more expensive due to the additional processing needed to create the frosted or textured effect, and spandrel glass can be costly due to the specialized coatings and treatments required to achieve its opacity.

It's important to think about the long-term benefits of each type of glass, such as energy savings and durability, to determine the most cost-effective solution.

Installation

Obscured glass can be relatively straightforward to install for experienced contractors. However, the textured surface of some types of obscured glass makes the process slightly more challenging.

Spandrel glass, particularly when used in large panels, often requires specialized equipment and expertise, which can increase labor costs and installation time.

At Panda Windows & Doors, we recommend hiring professionals to install your custom glass windows or doors.

Maintenance

Obscured glass, particularly those with textured surfaces, is more challenging to maintain because dirt and grime can accumulate in the crevices, requiring more frequent and thorough cleanings.

Spandrel glass, on the other hand, is easier because it is often installed in non-vision areas and does not require regular cleaning.

However, if the spandrel glass is damaged or needs replacement, it is way more costly and challenging to address due to its size and specialized coatings.

Aesthetics

Obscured glass provides a unique combination of privacy and light diffusion, which is useful in various residential and commercial applications. It is available in a wide range of patterns and textures, allowing for design versatility.

Spandrel glass, with its opaque finish, gives building facades a sleek and modern appearance. It is available in various colors and finishes.

Ideal Uses

Best Situations for Obscured Glass

  • Residential Spaces: In homes, obscured glass is often used in bathrooms to provide privacy while still allowing natural light to flood the space. It is also used in entry doors and sidelights to create a welcoming atmosphere without giving outsiders a clear view into your home.
  • Commercial Spaces: For commercial settings, obscured glass is a fantastic option for office partitions and conference rooms. It gives employees private areas to work or have meetings without being disturbed, while still benefiting from natural light. It can also be used in retail spaces, such as fitting rooms or storefronts, to enhance privacy and aesthetics.

Best Situations for Spandrel Glass

  • Commercial Buildings: In commercial buildings, spandrel glass is used to hide mechanical equipment, structural columns, and floor slabs between windows. This creates a clean, streamlined appearance that enhances the overall aesthetic of the building. It's also used in curtain wall systems to create a cohesive look while hiding unsightly elements.
  • Industrial Settings: In industrial settings, spandrel glass conceals machinery and other equipment that needs to be hidden from view. It’s a durable, low-maintenance solution that can withstand harsh environmental conditions — which is ideal for factories and warehouses.
