What Are Thermally Broken Windows And How Do They Work?

When it comes to energy-efficient windows, thermally broken windows have gained significant attention. These windows offer improved insulation and thermal performance, resulting in energy savings and increased comfort. In this blog post, we will delve into the concept of thermally broken windows, explore their construction and functioning, and discuss the benefits they provide. We will also examine the features of thermally broken double glazing and window frames, shedding light on their role in enhancing energy efficiency.

Understanding Thermally Broken Windows 

Unlike traditional windows that conduct heat, thermally broken windows incorporate a thermal barrier within the window frame to break the thermal bridge. This barrier acts as an insulator, preventing the transfer of heat or cold between the inside and outside environments. By reducing heat loss during winter and heat gain during summer, thermally broken windows help maintain a comfortable indoor temperature and reduce reliance on heating and cooling systems.

Thermally Broken Double Glazing 

Thermally broken double glazing takes the concept of energy efficiency even further. In addition to the thermal barrier in the window frame, it features two or more glass panes separated by a spacer filled with an insulating gas, such as argon. This design enhances insulation, reduces noise transmission, and improves overall energy efficiency. Combining a thermally broken window frame and double glazing creates a highly effective solution for thermal performance, providing better insulation than standard single-pane windows.

Thermally Broken Window Frames 

The construction of thermally broken window frames is crucial to their energy efficiency. These sections are joined by a non-conductive material, a thermal break. By minimizing heat conduction, the thermal break significantly improves the overall insulation and thermal performance of the window.

How Do Thermally Broken Windows Work? 

The functioning of thermally broken windows can be summarized in a few key steps:

Thermal Barrier: The primary element of thermally broken windows is the thermal barrier inserted within the frame. This barrier, made of non-conductive material, interrupts the flow of heat through the frame, preventing heat transfer between the inside and outside environments.

Insulating Air Gap: In the case of thermally broken double glazing, the insulating air gap between the glass panes further enhances energy efficiency. This gap is filled with a low-conductivity gas, such as argon, which reduces heat transfer through the window.

Reduced Heat Loss: The combination of the thermal barrier and the insulating air gap reduces heat loss from the interior during cold weather. It also prevents heat gain from the exterior during hot weather, helping to maintain a comfortable indoor temperature year-round.

Benefits of Thermally Broken Windows 

The advantages of thermally broken windows are numerous and significant:

Energy Efficiency: Windows that are thermally fractured restrict heat transfer, improving energy efficiency and reducing the need for heating and cooling systems. As a result, energy is saved, and utility costs are reduced.

Enhanced Comfort: By effectively insulating against external temperature fluctuations, thermally broken windows help create a more comfortable indoor environment throughout the year.

Control of condensation: Thermally broken windows’ better insulating capabilities lessen condensation on the interior surface of the glass, decreasing moisture-related problems including mold growth and window frame corrosion.

Noise reduction: By combining double glazing with thermal gaps in the window frame, you may create a quieter, more tranquil environment inside.

Reduced HVAC Load: By minimizing heat transfer, thermally broken windows help reduce the workload on heating, ventilation, and air conditioning (HVAC) systems. This can result in lower maintenance costs and an extended lifespan for HVAC equipment.

Environmental Impact: The energy efficiency of thermally broken windows contributes to reducing carbon emissions and environmental impact. It promotes sustainable living and aligns with eco-conscious principles.

Property Value: Installing thermally broken windows can increase the value of your property. Homebuyers are increasingly aware of the benefits of energy-efficient features, making thermally broken windows an attractive selling point.

Types of Thermal Breaks 

Thermal breaks in window frames can be achieved through different methods and materials. Some common types of thermal breaks include:

Polyamide Strips: Polyamide is a non-metallic material with low thermal conductivity. It is commonly used to create a thermal break in aluminum window frames. The polyamide strips are inserted between the inner and outer sections of the frame, effectively preventing heat transfer.

Insulating Foam: Another approach involves injecting insulating foam between the frame sections. This foam expands and hardens, creating a thermal barrier that reduces heat conduction.

Thermal Inserts: Some window systems use thermal inserts made of materials like fiberglass or reinforced polyamide. These inserts are placed within the frame to interrupt the thermal bridge and enhance energy efficiency.

Each type of thermal break offers its unique advantages and suitability for specific window frame materials and designs.

Installation Considerations 

When you’re planning to install thermally broken windows, it’s essential to consider several important factors. These factors will help ensure a successful installation and maximize the benefits of your thermally broken windows. One of the crucial considerations is to hire professional window installers who have expertise in working with thermally broken windows. 

Professional Installation: The installation process for these windows can be complex and requires specialized techniques. By hiring professionals, you can have peace of mind knowing that your thermally broken windows will be installed with precision and expertise, maximizing their energy efficiency and overall performance.

Customization Options: Thermally broken windows are available in various styles, colors, and sizes to suit your preferences and architectural requirements. Discuss customization options with your window supplier to achieve the desired aesthetic appeal.

Building Regulations: Check local building regulations and energy efficiency requirements to ensure that the chosen thermally broken windows comply with the necessary standards.

Conclusion 

Thermally broken windows are an excellent choice for homeowners seeking energy-efficient and sustainable solutions. By incorporating thermal breaks in the window frames and utilizing double glazing, these windows offer enhanced insulation, reduced heat transfer, and improved comfort. With their numerous benefits, including energy efficiency, noise reduction, and condensation control, thermally broken windows make a valuable investment for any home. Consider upgrading to thermally broken windows to enjoy improved thermal performance, energy savings, and more comfortable living space.
