Transom glass has been used for centuries as a decorative element in architecture. Its popularity has only increased with modern designs, where it is used for both aesthetic and functional purposes. Transom glass can be found in residential and commercial buildings, including homes, offices, and public spaces.
This article aims to provide a comprehensive guide on the different types of transom glass, its uses, and the maintenance required to keep it in good condition.
How Transom Glass is Made?
Transom glass is typically made using the same process as other types of flat glass, such as windows and mirrors. Here is a step-by-step breakdown of how transom glass is made:
- Raw Materials: The first step in making transom glass is to gather the raw materials. The main ingredient in glass is silica sand, which is combined with other materials such as soda ash, limestone, and feldspar to create a mixture known as “batch”.
- Melting: The batch is then loaded into a furnace, where it is melted at temperatures of around 1700°C. The molten glass is then poured onto a bed of molten tin, which helps to smooth out the surface of the glass and create a uniform thickness.
- Annealing: After the glass has been formed, it is cooled slowly in a process known as “annealing”. This helps to prevent the glass from cracking or shattering due to thermal stress.
- Cutting and Shaping: Once the glass has been annealed, it can be cut and shaped to the desired size and shape. Transom glass is typically rectangular or square in shape, with dimensions that are customized to fit the specific requirements of the building.
- Edging and Polishing: After the glass has been cut to size, the edges are typically polished to create a smooth, finished edge. This not only improves the appearance of the glass, but also helps to prevent the edges from chipping or cracking.
- Coating: Depending on the application, the transom glass may also be coated with a thin layer of metal or other material to improve its performance. For example, a low-e coating can help to improve the energy efficiency of the building by reflecting heat back into the room.
What are the Types of Transom Glass
Transom glass comes in various types and styles, each with its own unique characteristics and benefits. Understanding the different types of transom glass can help you choose the right option for your building’s design, functionality, and budget. Here are some of the common types of transom glass:
- Clear Transom Glass: Clear transom glass is the most common type of transom glass, and it’s often used to allow natural light into a room while maintaining privacy. This type of glass is available in various thicknesses, ranging from 3mm to 12mm, and can be tempered or laminated for added strength and safety.
- Frosted Transom Glass: Frosted transom glass is a popular choice for bathrooms, entryways, and other areas where privacy is a concern. This type of glass is treated with acid or sandblasted to create a textured surface that diffuses light and obscures visibility.
- Stained Glass Transom: Stained glass transoms are a beautiful and colorful addition to any building’s architecture. This type of glass is created by adding metallic salts to the molten glass during the manufacturing process, resulting in vibrant and intricate designs.
- Leaded Glass Transom: Leaded glass transoms are a classic and elegant choice that’s often used in traditional and historic buildings. This type of glass is created by assembling small pieces of glass using lead strips or caming to create a decorative pattern.
- Textured Transom: Glass Textured transom glass is a versatile option that adds visual interest and dimension to any building’s design. This type of glass can be made with various patterns, including ribbed, frosted, and reeded, and can be combined with other types of glass for a custom look.
- Insulated Transom Glass: Insulated transom glass is a great option for buildings that require energy-efficient solutions. This type of glass is made up of two or more panes of glass separated by an air or gas-filled space, which helps reduce heat transfer and noise transmission.
- Low-E Transom Glass: Low-emissivity (Low-E) transom glass is a popular option for buildings in areas with extreme temperature fluctuations. This type of glass is coated with a special metallic oxide that reflects heat and UV rays, helping to reduce energy costs and maintain a comfortable indoor temperature.
Overall, the type of transom glass you choose depends on various factors, including your design preferences, functional requirements, and budget. When selecting the right type of transom glass for your building, be sure to consult with a professional glass manufacturer or installer to ensure you get the best results.
