Frequently Asked Questions
What is a transom window?
A transom window is a small window located above a door or another window. Traditionally, transom windows were used for ventilation and to allow more natural light into a space. They are often hinged to open and close, although modern versions may be fixed. Transom windows can be found in various architectural styles and serve both functional and decorative purposes. They often add an element of elegance and can make a room feel larger and more open by providing additional light.
How much do transom windows cost?
The cost of transom windows can vary depending on several factors, including:
- Size and Shape: Standard rectangular transom windows are typically more affordable, while custom shapes like arches or circles can increase the cost.
- Material: Vinyl frames are budget-friendly, while wood, fiberglass, or aluminum frames are more premium.
- Glass Options: Standard clear glass is economical, but decorative, stained, frosted, or energy-efficient glass can add to the price.
- Customization: Features like intricate grilles, unique finishes, or specialized hardware will affect the overall cost.
- Installation: Costs depend on whether the transom is installed with a door, window, or as a standalone feature, as well as the complexity of the installation.
On average:
- Standard transom windows cost between $300 and $800 per unit, including basic installation.
- Custom designs or premium materials can range from $1,000 to $2,500 or more.
What are the key features and benefits of transom windows?
Increased Natural Light: Transom windows allow more natural light to enter a space, brightening rooms that might otherwise be dim. This can make interiors feel more open and welcoming.
Improved Ventilation: When designed to open, transom windows can enhance air circulation. This can be particularly useful in rooms where ventilation is needed but privacy or security is a concern, such as bathrooms or bedrooms.
Energy Efficiency: By increasing natural light and ventilation, transom windows can reduce the need for artificial lighting and mechanical cooling, potentially lowering energy bills.
Aesthetic Appeal: Transom windows add architectural interest and beauty to a building. They can serve as a design focal point, adding elegance and sophistication to both interior and exterior views.
Space Utilization: Since transom windows are usually small and located above doors or windows, they do not take up valuable wall space that could be used for furniture or artwork.
Historical and Decorative Value: In older buildings, transom windows can preserve the historical character. In modern buildings, they can be designed with decorative glass to add unique artistic elements.
Enhanced Views: In rooms with high ceilings, transom windows can offer views of the sky or treetops, creating a more connected feel to the outdoors.
Flexibility in Design: Transom windows come in various shapes and styles, allowing for flexibility in architectural design and the ability to match or complement other window styles in the building.
