Optimized Thermal Solutions for High-Performance Systems
Optimized Thermal Solutions for Maximum Efficiency
Achieving superior thermal performance in windows, doors, and curtain walls requires more than basic separation of aluminum components. Even with thermal breaks, heat transfer through radiation and convection can compromise insulation. The key to effective energy efficiency lies in carefully engineered insulation zones, designed to minimize air flow and thermal loss.
At Kronos, we offer a wide range of standard profiles—hollow chambers, inserting fins, and foam fillings—designed to enhance insulation without affecting system functionality. Beyond our standard solutions, we provide customized approaches to optimize thermal performance across your specific application, taking into account production methods, structural requirements, and environmental impact.
By working closely with you, we identify the most effective combination of profiles and solutions to achieve your performance goals, reduce energy consumption, and improve long-term comfort and reliability in high-performance building systems.
Inserting fins
As the width of thermal insulation strips increases, larger structural cavities form in the insulated zone of window and door profiles (the space between paired insulation strips and the surrounding interior and exterior aluminum). These cavities can promote convection, reducing thermal performance.
The Kronos insert-type thermal insulation strip solution addresses this by segmenting the insulation cavity, controlling convective heat transfer, and optimizing the profile’s insulation efficiency. We offer a range of strip widths to reduce heat loss, simplify production, and lower inventory complexity—providing aluminum window and door systems with a flexible, cost-effective thermal insulation solution.
Thermal Insulation Strips with Adhesive foam
As the width of thermal insulation strips increases, larger structural cavities form within the insulated zone of window and door profiles (the space between paired insulation strips and the surrounding interior and exterior aluminum), which can promote convective heat transfer. Filling these cavities with foam is an effective way to enhance the thermal performance of windows and curtain walls.
The challenge lies in identifying a low-thermal-conductivity material that can seamlessly withstand standard PA66GF25 insulation strip processes, including transport, storage, lamination, and surface finishing. Kronos has successfully tested PE foam, a closed-cell material with a thermal conductivity of 0.034 W/mK and a density of 24.9 kg/m³, delivering improved insulation performance while maintaining process compatibility.
