Optimizing Building Energy Efficiency through High-performance Facades
Heat Gain through Aluminium Frames
Aluminium windows are commonly used in both commercial and residential buildings: they are easy to fabricate, have good mechanical strength and visually appealing. However, aluminium is a good conductor of heat, which results in significant heat gain through the framing member. This means that a higher cooling load is required to cool the building down.
To overcome this, we can tap on the use of a thermal break, which separates the interior and exterior aluminium sections and prevents the conduction of heat due to its thermal insulating material.
Technoform thermal break profiles are made of glass-fibre reinforced polyamide (PA66 GF25), an engineering plastic with:
- Low thermal conductivity (~533 times lower than aluminum)
- Excellent mechanical properties
Thermal performance improvement
We conducted a thermal simulation and through the use of a thermally broken system, the frame performance has improved by over 70% from 17.1W/m2K to 3.2W/m2K.
If you have any upcoming projects, we can support you with a thermal simulation report to show the performance improvement with the use of thermally broken system. Contact us here.
Window systems development
Frame U-value improves with increasing width of the thermal break, and will also be affected by other factors, such as the shape of the thermal break. Technoform offers more than 800 freely available geometries to suit your requirements.
We are also the expert in thermal zone engineering for windows, doors and facades. We can provide relevant support such as U-value simulations for your project needs, and support the design and optimization of your drawings.
Benefits of thermally broken window systems
Stringent testing to ensure the highest quality
Why is a good thermal break important?
The use of a thermal break with inferior quality may result in cracks or even breakage during the assembly process. With a good quality thermal break as well as proper execution of the assembly processes, it will ensure a good shear strength for an assembled thermally broken aluminum profile.
In addition, a good thermal break is critical in allowing the facade to serve its intended design use and lifespan, ensuring the safety and durability of the facade. This is especially since building facades are constantly exposed to environmental loads such as wind and temperature changes. Hence, the frames will undergo behavior changes including bending and shearing, and it is important to ensure the mechnical properties of the assembled profiles.
Quality is key for us
We have always been dedicated to testing our products to the core, providing various checking and testing procedures to guarantee a product of highest quality - always. Globally, we adhere to the most stringent standards, ensuring consistent quality in all our products.
Our plants worldwide are also ISO 9001 certified. Thanks to the standardization of the processes, our products can be made in any of our production plants with no variation in quality.
