What is a thermal break window?

The working principle of an aluminum thermal break window lies in the structure of its profile. Ordinary aluminum profiles, due to the high conductivity of the metal, easily transfer heat and cold. In contrast, thermal break profiles are composed of two separate aluminum sections connected by a non-metallic separator with a low heat transfer coefficient. This separator, usually made of polyamide reinforced with fiberglass, acts like a thermal barrier, preventing direct heat transfer between the inside and outside of the building. Thus, what thermal break technology is, is clearly evident in this structure. The main difference between thermal break and normal break is also in this insulated structure; in normal break windows, the aluminum profile is continuous and lacks this insulating layer.

Types of Aluminum Thermal Break Windows

The diversity in the design and application of modern buildings necessitates that windows are also produced in various shapes, sizes, and functions. Fortunately, the types of thermal break windows have adapted well to these needs, offering a wide range of options to clients, architects, and designers. This variety not only plays a role in the visual beauty of the facade and interior decoration but is also effective in the optimal performance of the space and the required amount of ventilation. In fact, choosing the right type of thermal break window and installing aluminum windows can directly impact the efficiency and comfort of the building’s occupants. The types of aluminum thermal break windows include:

Casement Windows: This model is one of the oldest and most common types of windows. By opening in a swinging motion around one or more vertical axes, it provides complete and easy ventilation. The simple yet efficient design of these windows makes them suitable for many spaces.
Sliding Windows: In spaces where there are limitations in opening the sashes inward or outward, sliding windows are considered an ideal solution. These windows, with their horizontal movement of sashes on a track, allow connection with the outside environment and ventilation without occupying extra space.
Fixed Windows: These types of windows do not have the ability to open and are used to provide abundant natural light and create a wide view of the outside environment. Fixed windows can be designed and implemented in various sizes and shapes and are often used in combination with other types of opening windows.
Tilt and Turn Windows: This type of aluminum thermal break window is a clever combination of casement and tilt-in (Tilt & Turn) functionality. The casement mode allows for full opening for ventilation, while the tilt-in mode provides gentle and secure ventilation without worrying about unauthorized entry or pets.
Tilt and Slide Windows (Volkswagen Windows): These windows are a more advanced type of sliding window that first tilt slightly inward before being slid to the sides. This mechanism creates better sealing and smoother operation when opening and closing.
Lift and Slide Windows: These types of windows are designed for very large and heavy openings. Their operating mechanism is such that the sash is first lifted slightly using a handle and then easily moves on the track. These windows have excellent insulation and are very suitable for creating open and integrated spaces with the outside environment.

Advantages of Using Thermal Break Windows

Due to its unique features, the aluminum thermal break window brings a set of significant advantages to modern buildings and has therefore become an ideal option. In fact, the advantages of aluminum windows reach their peak in the thermal break structure, demonstrating a performance beyond that of a simple building element. The most important of these advantages are:

Excellent Thermal Insulation: The thermal break structure prevents heat transfer, helping to maintain a comfortable indoor temperature in both hot and cold seasons. As a result, it significantly increases energy efficiency, leading to reduced cooling and heating costs and ultimately optimal fuel consumption.
Easy Maintenance: The smooth and non-porous surface of aluminum is easy to clean and does not require repainting or complex maintenance.
Good Sound Insulation: In addition to thermal insulation, the multi-layered structure and the use of double or triple glazing in aluminum thermal break windows also provide good sound insulation, preventing the entry of external noise pollution into the building.
High Durability and Strength: Aluminum is inherently a strong and durable metal with high resistance to various weather conditions, including humidity, sunlight, and temperature changes. Due to this feature, aluminum windows have a long lifespan and require minimal maintenance. They are also resistant to rust.
Modern and Beautiful Design: Due to the high formability of aluminum profiles, it is possible to design windows in various shapes and sizes with a modern and stylish appearance. This helps architects and interior designers to best match modern and luxurious facades.
Environmental Friendliness: Aluminum is a recyclable material, and its use in window construction helps conserve natural resources.
Compatibility with Iran’s Climate: Considering the climatic diversity in Iran, the thermal insulation feature of aluminum thermal break windows makes it a suitable option for various regions of the country.

Limitations and Disadvantages of Thermal Break Windows

Despite the numerous advantages, the disadvantages of aluminum thermal break windows are also worth considering. One of the most important is the price of thermal break windows, which is usually higher than UPVC windows or ordinary aluminum windows. Also, in case of improper installation and the use of low-quality raw materials, its insulation performance may not be fully realized. However, considering the long lifespan and reduced energy costs, this initial cost will be compensated for in the long run.

Common Applications of Aluminum Thermal Break Windows

The application of thermal break windows in buildings is very extensive and includes the following:

Luxury and modern residential buildings
Commercial and office buildings
Hotels and hospitals
Renovation projects of old buildings with the aim of improving insulation
Buildings with large and modern glass facades
Regions with harsh climatic conditions (extreme heat or cold)

The difference between thermal break windows and regular windows

The main difference between thermal break windows and regular windows (especially normal break aluminum windows) lies in their profile structure. In regular windows, the aluminum profile is continuous and easily conducts heat. This leads to greater energy loss and the creation of a thermal bridge, which can cause condensation and mold growth inside the building. In contrast, the thermal break structure significantly reduces these problems by creating a thermal barrier. Also, comparing thermal break windows with double-glazed windows shows that while both types of windows are effective in reducing heat transfer, thermal break windows perform better in this regard due to their insulated profile structure. Of course, double or triple glazing is also commonly used in aluminum thermal break windows to maximize insulation.
