Aluminum is a highly thermal conductive material that will rapidly transfer exterior climatic temperature unless something is done to stop the thermal conduction. A Thermal Break (also known as Insulating Profile, Thermal Barrier, 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. 

A POLYAMIDE thermal break system will improve thermal performance while maintaining the structural and long-term durability of the fenestration unit. Aluminum is 533 times more conductive than polyamide insulating strips. Thermal Strut involves two separate extrusions and joins them through the use of engineered structural polymide strut. Both the inside and outside aluminum profiles are extruded independently with a cavity that will ultimately receive the strut.

Kronos Precision Extrusion is the leading manufacturer and supplier of high-end Glass Reinforced Polyamide Insulating Profiles for many of most energy-efficient aluminum window, door, and curtain wall products with growing presence in international markets. 

Our thermal strut is made of fiberglass reinforced virgin polyamide with glass fibers oriented in 3 directions for optimal structural performance. Strut offers increased energy savings with varying thermal separation widths including those greater than any other thermal break system. Structural performance and mechanical response are exceptional with the multidirectional glass fibers oriented in 3D to give improved load transfer.

Across the globe, Kronos Precision Extrusion is recognized for its high performance polyamide insulating profiles for aluminum windows, doors, façades, cutain wall systems and fenestration systems. These products help save an estimated 500,000 kWh of energy each year, significantly reducing the global level of CO₂ emissions.

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 country's stringent green building codes and standards in the market today.

Kronos thrives upon Wide and Complex polyamide extrusions that challenge today's extrusion capabilities. We pride ourselves in taking on the thermoplastics extrusions that others say Can't Be Done or Too Difficult. 

The strength of Kronos Precision Extrusion is the quality of the thermoplastic profiles supplied and the competent services offered to our customers. We always prioritize our effort in providing products that are in accordance to the requirements to meet international standards. The success of Kronos lies on the satisfaction of our customers. Kronos's 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.

Benefits of High Precision Extruded PA66 GF25 Thermal Insulation Polyamide Profiles:

• The Polyamide Strips are mechanically bonded between the aluminum frames.

• The Polyamide Struts and the aluminum frames have almost identical coefficients of expansion. As a result, thermal break systems resist the thermal cycling, which occurs in actual building conditions better than any method available in today's market.  

• Thermal Break Polyamide Profiles will withstand heat in fenestration systems better than any other system, resulting in improved structural integrity.

• The use of polyamide strut also allows for endless new product design. With this method the two separate extrusions can easily have different paint or anodize combinations, which adds significant flexibility to each individual use.

• Increased Structural Strength.

• Ability to make various window and door systems with the same aluminum profiles, using different sized and shaped polyamide insulating struts.   

All batches of Kronos's polyamide profiles are subject to a rigorous inspection process prior to delivery.

Kronos provides standard and custom Laser Marking for easier traceability and improved quality control, adding extra value to your products and company.
