Overview

Aluminium is massively used in the manufacturing of profiles for the building and construction industry in window, door, facade, and curtain wall systems. Αluminium frames are the ideal solution that will provide you with very robust doors and windows and, therefore, increased security and long-term durability, however aluminium frames are lacking when it comes to heat and sound insulation. 

The thermal conductivity of aluminium alloy is 160W/M².K, which makes it a very good conductor of heat. However, every nation's legislation and building code are becoming stricter in terms of energy efficiency. The purpose is to reduce CO₂ emissions and to save energy. Since aluminium is one of the best materials to make window and door frames, architects and engineers just simply love it. To solve this problem, a thermal break is required.

A Thermal Break, also known as Thermal Strut or Thermal Barrier, is an element of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials. 

The thermal broken system consists of two independent aluminium profiles with similar or unlike shapes connected by Polyamide 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. 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, which has for years been providing Thermal Insulation Solutions, is playing a significant role in enhancing the Thermal Energy Efficiency of buildings around the world with its high-performance and Thermally-Insulating Polyamide Insulation Strips for Thermal-Break aluminium frames. 

Made of high-performance Virgin polyamide 6.6 with 25% Pure glassfibre reinforcement(PA66GF25), thermal insulation polyamide profiles provide greater structural integrity and heat insulation for aluminium windows, doors, facades, and curtain-wall systems than every other alternative thermoplastic available.

In terms of Dimensional Stability and Tight Tolerances, Kronos's reinforced polyamide thermal-barrier systems outperform every other thermal-barrier method. The bond between the strip and the aluminium frame is a true mechanical connection method. In addition, the strip and the aluminium frame have identical coefficients of expansion and contraction. As a result, Kronos's polyamide thermal-barrier systems resist the thermal cycling that occurs in actual building conditions better than any available method. 

Kronos's High Efficiency polyamide insulating profiles set new standards in thermal separation, permit excellent U values and are the first choice in low-energy and passive buildings.
