Polyamide 66 reinforced by 25% glass fiber Thermal Break Strip inserted into aluminium window, door and facade profile for thermal insulation

MODEL: Shape S 30.6 mm

30.6 mm width extruded large heat break nylon profile for curtain walls. Used in curtain wall system, or in facade system, and being the part of energy-saving window system for reducing heat conduction. Shapes can be customized, we're majored in designing and developing polyamide profiles for window system.


The performance of thermal barrier strips are in line with the Chinese standard GB/T 23615.1-2009 and the European Standard EN 14024:2004, for KAXITE series, the performance is rather higher than the standard value.

Details of related standard:

GB/T 23615.1-2009 Accessorial material for architectural aluminum alloy profiles -- Part 1: Thermal Barrier Strip of polyamide

EN 14024-2004 Metal profiles with thermal barrier -- Mechanical performance Requirement, proof and tests for assessment

YS/T 437-2008 Aluminium profiles moment of inertia calculation methods and computing software requirements

JG/T 174-2005 Thermal barrier strips for construction industry

GB 5237.6 -2012 Wrought aluminium alloy extruded profiles for architecture -- Part 6: Thermal barrier profiles

GB/T 8478-2008 Aluminium windows and doors

GB/T 8484-2008 Graduation and test for thermal insulating properties of doors and windows

JG 175-2011 Insulating aluminum alloy profiles with thermal barrier for buildings

In 2015, we became the leader of the Chinese National Standard Committee (for revising of GB/T 23615.1-2009) .

For quality, the most important thing is to control the performance of the raw materials, as we have to ensure the expensive but indispensable additives (e.x. Antioxidants & Anti-aging agents) were contained in the mixture. We have our own capacity of granulation for PA66 GF25 and many other kinds of plastic granules. We're the only one who used the technology of Vacuum Drying for the polyamide, which could highly improve the natural performance of the nylon granules.

We have series of brands, corresponding to different raw materials. For domestic series, they will be the domestic new PA66 and short chopped fiberglass, for KAXITE series, they will be the imported Dupond PA66 and short chopped fiberglass, which has rather better performance than the standard required.


Mostly we could finish the development of new products in 15 days.

The hardest thing is not thinking, but realizing. Most customers were upset that nobody could develop the shapes that they designed, some counterparts even came and looking for help to our workshop. We developing and cutting new dies for our customer, of course we never failed to develop any shape for our customers.


We have more than 40 extruders, production capacity of 550,000 meters per day. For common specifications, they're ready in stock, if customized, mostly the production could be finished in 7 days.


For all specifications/shapes, they could be packaged in linear, the length will be 6 meters, or customized.

For the Shape "I", "C", and some simple shapes, they can be packed in rolls. 400-600 meters/roll.


Polyamide is a typical hygroscopic resin, so we adopt vacuum dryer to reduce its water content and ensure its high quality.
