Overview

Aluminium is massively used in the manufacturing of profiles for the building and construction industry in window, door, facade, and curtain wall systems. The thermal conductivity of aluminium alloy is 160W/M².K, which makes it a very good conductor of heat. However, the international legislation and building codes are becoming stricter in terms of energy efficiency. The purpose is to reduce CO₂ emissions and to save energy. To solve this problem, a thermal break is required.

The thermal broken system consists of two independent aluminium profiles with similar or unlike shapes connected by Polyamide 66 Insulating Strips(Polyamide Profiles) in order to obtain one monolithic profile having low UV factor and low transmission sound. This will minimize heat transfer between the interior and exterior of aluminium doors and windows, which will improve the energy saving much better than traditional systems.

The thermal conductivity of polyamide profile is only 0.3W/M².K, which is 533 times less than that of aluminium, making it a perfect insulating material for thermally broken aluminum systems. The lower the U value (the thermal conductivity), the better the insulation. Not only that, polyamides have very similar coefficient of expansion and contraction to aluminium. Polyamide Insulating Struts reduce internal aluminum frame stress effectively and will not separate over years of seasonal hot-cold cycles. Water and air will not penetrate this superior thermal barrier.

Kronos Precision Extrusion, the leading developer and manufacturer of Polyamide Insulating Profiles, is playing a significant role in enhancing the Thermal Energy Efficiency of buildings around the world with its high-performance Polyamide Insulation Strips for Thermal-Break aluminium frames. 

The use of thermally broken aluminum profiles with Kronos's  polyamide strips for windows, doors, facades, and curtain walls offers a considerable improvement in the energy performance of buildings, helping to cut the polluting emissions. Meanwhile, our PA profiles also contribute a massive reduction of energy costs to air-conditioning buildings, whether for heating or cooling purposes.

Kronos Precision Extrusion thrives upon Wide and Complex polyamide extrusions that challenge today's extrusion capabilities. Extrusions others say Can't Be Done are usually just Easy Jobs for us. 

The technical know-how accumulated over dacades of experience in supplying PA66 insulating strips to the leading manufacturers of aluminum windows, doors, facades, and curtain wall systems in China and worldwide, enables KRONOS to technically team up with the clients in the development of new highly performing systems, or improving the insulating properties of the existing ones.
