Overview

What is a thermal break?

A Thermal Break (aka. Insulating Profile, Thermal Barrier Strut, Insulating Bar) is a poor conductor of heat. It separates the outer and inner aluminum frames thermally from each other. This plastic thermal barrier profile acts as a barrier to prevent direct heat transfer through highly heat conductive aluminum profile. 

As an environmentally friendly material, Polyamide (Nylon) is the best and the most popular material for thermal break strips. Heat insulating profiles made of polyamide PA66 GF25% (25% fiber glass reinforced polyamide) have significant advantages. Polyamide profiles do not emit toxic gas in case of fire, on the other hand, the coefficient of linear thermal expansion (linear elongation coefficient) of the polyamide profiles is almost equivalent to the aluminum profile. Therefore, the polyamide profile is not subjected to internal stresses after it is pressed to aluminum profile. 

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 Thermally Broken 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.  

Extremely Smooth Surfaces, Tighest Tolerance, Outstanding High Precision, all of these set Kronos apart from other thermoplastics extruders. Our polyamide profiles yield best-in-class thermal performance and exceeds not only current codes, but also exceeds every countries' stringent green building codes and standards in the market today.

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.

Our team has extensive expertise in new product development of thermoplastic extrusions, which allows us to be flexible and quickly adaptable to meet your specific needs. Our manufacturing capabilities span a broad range of products and thermoplastic polymers which makes us the perfect partner for all of your standard and tailor-made precision thermoplastic profiles extrusion needs.

Aiming always for the best quality, energy efficient aluminium windows, doors, facades, and curtain wall systems using Kronos's polyamide insulating profiles are the absolute first choice for new constructions and renovation projects in which compromise is not an option.
