While Little Giant specializes in fiberglass steeples and baptisteries, we’re also a trusted supplier of cupolas and domes for churches, mausoleums and chapels.

These ornamental structures are an elegant accent for any religious facility, and our fiberglass designs offer a low-maintenance, durable option for new buildings or existing structures.

What is a Cupola?

  • A fiberglass cupola is a decorative architectural structure typically found on the roof of buildings, especially traditional or historic structures. It serves both functional and aesthetic purposes, adding charm, character, and visual appeal to a building’s overall design. A cupola is typically dome-shaped or square and features windows or louvers on its sides for ventilation and light.

    Here is a detailed explanation of what a fiberglass cupola is:

    1. Design and Construction:

      • Shape and size: Fiberglass cupolas can come in various shapes, including square, rectangular, hexagonal, or octagonal. The size of a cupola depends on the scale and proportion of the building it is intended to adorn.
      • Materials: Fiberglass is a popular choice for cupolas due to its lightweight nature, durability, and weather resistance. It can be molded into intricate details and designs, allowing for customization and replication of traditional architectural styles.
      • Ventilation and lighting: Cupolas often have windows or louvers on multiple sides, allowing for natural ventilation and the passage of light into the building’s interior.
    2. Functional Purposes:

      • Ventilation: Cupolas are designed to provide effective air circulation and ventilation within the building. The windows or louvers allow hot air to escape, keeping the interior cool and preventing the buildup of moisture.
      • Lighting: Cupolas with windows allow natural light to enter the building, reducing the need for artificial lighting during the day and creating a pleasant atmosphere inside.
    3. Aesthetic Enhancements:

      • Architectural character: Fiberglass cupolas add a distinct architectural character to a building, giving it a unique identity and enhancing its overall aesthetic appeal.
      • Historic charm: Cupolas are often associated with traditional or historic architectural styles, such as Colonial, Victorian, or Georgian, and can help preserve the authenticity and charm of older buildings or create a nostalgic atmosphere in newer structures.
      • Customization: Fiberglass cupolas offer a wide range of design possibilities, allowing for customization to match the architectural style and specific requirements of the building. They can be painted or finished to complement the building’s color scheme or replicate the appearance of other materials such as wood or metal.

    In summary, a fiberglass cupola is a decorative and functional architectural element that adds visual appeal, ventilation, and lighting to a building. It can be customized to match various architectural styles and is a durable and low-maintenance choice for enhancing the beauty and functionality of structures.

What factors should I consider before purchasing a fiberglass church cupola?

When purchasing a fiberglass church cupola, there are several important factors to consider. These factors will help ensure that you make the right choice and select a cupola that meets your specific needs and preferences. Here are the key considerations:

  1. Size and Proportions:

    • Determine the appropriate size of the cupola based on the dimensions of your church building. Consider the roof pitch, overall height, and the scale of the cupola in relation to the structure.
    • Ensure that the proportions of the cupola are aesthetically pleasing and harmonize with the architectural style of the church.
  2. Design and Style:

    • Choose a cupola design that complements the overall architectural style of your church. Whether it’s a traditional, modern, or custom design, ensure that it aligns with the visual character of the building.
    • Consider decorative elements such as louvers, windows, or ornamental details that enhance the cupola’s visual appeal.
  3. Ventilation and Functionality:

    • Evaluate the cupola’s ventilation capabilities. Ensure it provides adequate airflow to help regulate temperature and control moisture inside the church.
    • Check if the cupola is designed to accommodate functional elements such as windows, louvers, or a weather vane.
  4. Quality and Durability:

    • Look for a high-quality fiberglass cupola that is durable, weather-resistant, and capable of withstanding the elements. Fiberglass is known for its strength, longevity, and low-maintenance properties.
    • Consider the reputation and expertise of the manufacturer to ensure that the cupola is constructed with precision and meets industry standards.
  5. Installation and Mounting:

    • Evaluate the installation process and requirements for the cupola. Ensure that it can be securely mounted on the roof of your church.
    • Consider the weight of the cupola and any additional supports or reinforcements needed during installation.
  6. Budget and Cost:

    • Establish a budget for your cupola purchase. Take into account the size, design, and additional features you desire while considering the overall cost, including installation and any customization options.

By considering these factors, you can make an informed decision when choosing a fiberglass church cupola. It is essential to select a cupola that not only enhances the architectural beauty of your church but also meets your functional and budgetary requirements.

Fiberglass Church Cupola Maintenance & Repair

Fiberglass cupolas are not only beautiful architectural additions to buildings but also durable and low-maintenance. However, like any other structure, they may require occasional maintenance and repair to keep them in optimal condition. Here are some essential tips for fiberglass cupola maintenance and repair:

  1. Regular Inspection:

    • Periodically inspect the cupola for any signs of damage, such as cracks, chips, or loose components.
    • Check the windows or louvers for proper functioning, ensuring they open and close smoothly.
    • Examine the fasteners and joints to ensure they are secure and in good condition.
  2. Cleaning:

    • Clean the cupola’s exterior surfaces regularly to remove dirt, dust, and debris. Use a mild detergent and a soft cloth or sponge to avoid scratching the fiberglass.
    • Avoid using abrasive cleaners or tools that can damage the finish or paint.
    • Rinse the cupola thoroughly with water after cleaning to remove any residue.
  3. Repairs:

    • For minor cracks or chips, apply a high-quality fiberglass repair kit following the manufacturer’s instructions. This typically involves cleaning the damaged area, applying the repair material, and sanding it down to achieve a smooth finish.
    • If significant damage or structural issues are present, it’s best to consult a professional contractor experienced in fiberglass repairs. They can assess the extent of the damage and recommend appropriate repair solutions.
  4. Painting and Finishing:

    • If you wish to change the color or refresh the appearance of the cupola, consider using a high-quality exterior paint or gel coat specifically designed for fiberglass surfaces. Ensure the cupola is thoroughly cleaned and properly prepared before applying any paint or finishing products.
    • Follow the manufacturer’s guidelines regarding application techniques, drying times, and recommended number of coats.
  5. Weather Protection:

    • Protect the cupola from extreme weather conditions, such as heavy snow loads, hail, or strong winds. Regularly clear snow and debris from the cupola’s roof and ensure it is securely attached to the building’s structure.
    • Consider applying a protective coating or sealant to the cupola’s exterior to enhance its resistance to UV rays, moisture, and other environmental factors. Consult with a professional to choose the appropriate product for your specific cupola.

By following these maintenance and repair practices, you can ensure the longevity and beauty of your fiberglass cupola. Regular inspections, cleaning, and prompt repairs will help preserve its structural integrity and aesthetic appeal, allowing you to enjoy its architectural charm for years to come.
