HK curtain wall customized polyamde break strip

Hollow Customized High Precision Polyamide Extrusion Thermal Break Strip

Product Description

 Detailed Information:

Hollow HK 14.8 mm customized heat broken strut for curtain walls can be used on 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. KAXITE Series polyamide thermal break profiles have better life as long as the aluminum and the buildings themselves.
Technical Performance:

    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
  • UL94 Standard for Tests for Flammability of Plastic Materials for Parts in Devices and Appliances
  • ASTM E84 Standard Test Method for Surface Burning Characteristics of Building Materials
  • NFPA 285 Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-Load-Bearing Wall Assemblies Containing Combustible Components

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

(KAXITE Series)(made of pure new raw material of PA66), you can see the extremely better performance of thermal break polyamide strips as shown below:

Raw Materials & Granulation:
We granuled by ourselves to ensure the quality of raw material for PA66GF25 thermal insulation strips.
   What's the most important component in the raw material of Heat Insulation Profiles for windows & doors? Not Dupond, not extremely expensive fiberglass, it's Anti-aging agent and Antioxidants.
   Think what will happen if there's no such anti-aging agents or antioxidants? Heat Insulation Profiles for windows & doors may age fastly by exposing to wind and sun,and maybe  just for less than 10 years, the polymer profiles would break and glasses and windows will fall from such high curtain walls!! It's deadly! In addition, most completed raw materials in the market for thermal barriers manufacturers have no antioxidants which it must be added  just beacause of its high cost. We have our own capacity of granulation to ensure that our raw materials contain these important elements to avoid this situation happening!

Our Services

OEM of Performance (Granulation)!

We support customizing any special performance of polyamide thermal break strips, even flame retardant required.
OEM of Shapes (cutting dies)!

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

It is hard for us to realize rather than think.  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 develop and cut new dies for our customer and we are so proud of that we never failed to develop any shape for our customers. 


Service Advantages: 
Whichever shape you need for the heat insulation profiles for windows & doors , we can develop the mould in a short time and send you the samples. In fact, we have solved so many problems for our customers and they are satisfied. 
2, We offer the most advancing laser marking machine for custmers if a special mark on the heat insulation strip is needed; 
3, Here we offers most sizes from 10mm width to 60mm or even bigger heat insulating strips. So,what is  your best favor? 
4, We provide matching equipment of PA66 thermal barrier profiles for customers for the corresponding service followed.

Storage Conditions: 
It’s better to be stored in ventilated and dry environment, should be put horizontally, keep away from water, rain, heat, stress and avoid acids, alkalis and organic solvents meanwhile.

Straight: 6 m / bar, 10~100 pieces per bundle as you like.
Roll bar: 500 meters / roll (only for the shape I and shape C pieces.

 Question: What is heat insulation profile?

  • Heat Insulation Profiles for windows & doors are made from resins that create a “thermal break” between the inner and outer surfaces of aluminum fenestrations. 
  • Heat Insulation Profiles for windows & doors reduce heat loss or heat gain through the aluminum.
  • Heat Insulation Profiles for windows & doors improve the U-value characteristics of finished systems.
  • Heat Insulation Profiles for windows & doors are about energy conservation, U-values and government codes
  • 70% of aluminum fenestration systems produced in North America contain a thermal break
  • Primarily used in colder climates to reduce heat loss
  • Increasing use of thermal barriers to reduce heat gain and also reduce heat loss
  • Developers, architects and designers are demanding better performance in terms of power usage
  • Stricter government regulations to reduce power usage in buildings to combat environmental concerns
  • Aluminum, if it is to retain its market superiority in terms of its structural integrity, will have to achieve better performance in terms of U-values
  • The use of Heat Insulation Profiles for windows & doors will assist manufacturers to achieve improved LEED performance   
The data in "What is Heat Insulation Profiles for windows & doors" was derived from the AAMA/WDMA U.S. Industry Statistical Review and Forecast - 2008/2009 (Published April 2009)
Product features?
1, The Heat Insulation Profiles for windows & doors were manufactured in line with Chinese national standards GB/T 23615.1-2009, with extremely high mechanical strength and withstand tensile shear stress, can be acted as the connecter to the hardware; if you need higher properties, please choose our kaxite series polyamide profiles which were produced with pure new raw materials, most of these PA66 particles were purchased from Dupond, and all the finished polyamide profiles were in compliance with the European standard UNE EN14024. 
2, The linear expansion coefficient is close to aluminum, to ensure that when temperature changes, the Heat Insulation Profiles for windows & doors and aluminium profiles expanding in the same time to ensure fitting closely; 
3, Highly heat distortion temperature, to meet subsequent processing on the surface of profiles; 
4, High dimensional accuracy, ensuring airtight, watertight performance of the windows breaking thermo with polymer profiles; 
5, Anti-aging, anti-UV performance, long using life;
