Aluminium windows are undoubtedly a dynamic and aesthetically pleasing addition to any space, thanks to their modern and sleek appearance that elevates the overall look of a room. At the same time, they offer more than just visual appeal—they also play a significant role in enhancing a home’s functionality, particularly by improving its energy efficiency.
Crafted from premium materials, aluminium windows offer exceptional strength and durability, making them a reliable long-term investment for any property. Their style and design can be tailored to match the unique characteristics and aesthetics of each residence, providing homeowners with a wide range of options to choose from, ensuring a perfect fit for their needs.
To begin with, a basic introduction to the “anatomy” of aluminium windows, they are primarily made up of two main components: the glazing (glass pane) and the aluminium frame, also known as the aluminium profile. These profiles fall into two main categories: conventional (or non-insulated) and thermal break. The latter, thermal break aluminium windows, are the central focus of this article.
The primary difference between thermal break and conventional aluminium profiles lies in thermal insulation. Thermal break profiles incorporate a special insulating material placed between the inner and outer sections of the frame. This insulating barrier effectively prevents heat transfer, whereas conventional profiles allow considerable energy loss due to their high thermal conductivity.
What does this mean in practical terms? Thermal break window frames help maintain a stable indoor temperature throughout the year—cooler in the summer and warmer in the winter—reducing the need for heating or cooling. In essence, they function as a buffer zone between the interior and exterior environments, making them an ideal choice for areas with extreme or fluctuating weather conditions.
How is thermal break achieved?
The key role is played by polyamide — a specialized, high-performance insulating material. Polyamide has low thermal conductivity and excellent mechanical strength, which is why it is widely used in thermal break aluminium profiles.
In practice, the window frame profile is divided into two sections—the interior and the exterior. Between these two parts, polyamide is inserted, acting as a thermal barrier. This configuration ensures complete thermal separation, significantly minimizing heat transfer between the inside and outside of the building.
Finally, it is worth noting that polyamide is highly resistant to both high and low temperatures, UV radiation, and chemical exposure, making it particularly well-suited for use in exterior window and door systems.
Advantages
Thermal break aluminium windows significantly reduce both heat and sound conductivity, providing improved insulation and overall energy efficiency. This results in better thermal comfort inside the home and reduced need for heating or cooling systems.
The presence of polyamide helps prevent condensation — the buildup of moisture on interior surfaces — which is a primary cause of mold on walls and window frames. As a result, a healthier and more comfortable indoor environment is maintained.
Another important advantage is the increased durability of materials. Thermal break frames require minimal maintenance, and their resistance to time and harsh weather conditions makes them a highly reliable choice. Their color remains unchanged over the years, and the risk of corrosion is significantly reduced. Thanks to their robustness against external factors, they contribute to maintaining a stable and pleasant indoor climate, enhancing both comfort and quality of life.
Special attention should be paid to the thermal transmittance coefficient (U-value), which measures a window’s insulating capability. The lower the U-value, the better the insulation. Thermal break aluminium windows achieve particularly low U-values—ranging between 1.1 and 0.6 W/m²K—making them ideal for modern, energy-efficient homes.
In conclusion, thermal break aluminium window systems represent a modern and efficient solution that combines high aesthetics, energy performance, and long-term durability. By incorporating materials like polyamide and advanced engineering into their structure, they offer excellent thermal insulation, moisture protection, and soundproofing—contributing significantly to improved everyday living conditions.
They pose a long-term investment with both economic and environmental benefits, making them an ideal choice for anyone seeking comfort, functionality, and resilience in their home or professional space.
