How to thermal barrier aluminum profile?


As thermal barrier aluminium profile has the following advantages and it is widely used in the window and doors projects and curtain wall project in the building


1 Remarkable energy saving effect, energy saving can be 30-40%

2 excellent sound insulation performances can reduce noise 30-50Db.

3 superb anti-frosting and antifogging performance, the window can be clean and bright

4 High strength, wind resistance performance can be 1 level standard

5 Good airtight and watertight performances, both is 1 level standard

6 Three chambered design principle, high stability of structure, excellent mechanical properties.

7 Advanced strip feeding technology, with reasonable structure, firm combination, good rigidity features, heat insulation effect is better

8 Thermal barrier aluminum profile can be anodized, electrophoresis, powder coated and fluorocarbon coated, rich varieties, good performance, ideal energy saving and sound insulation effect.


You may wonder how to make the thermal barrier aluminum profile in the extrusion factory; here we show the story behind and the steps


How to thermal barrier aluminum profile?  All you need are aluminum profiles, thermal break aluminum making machine and nylon strip. 


Here the thermal barrier aluminum profile is strip feeding method thermal insulating profile, not injection thermal barrier aluminum profile.  If you want to check the difference between strip feeding and injection methods, you can check for more information.


What is thermal barrier aluminium profile?

Two pieces of aluminum profiles are connected by polyamide strip. Aluminum can transfer heat or cold very easily, its thermal conductivity is high. But polyamide strip’s thermal conductivity is very low, and then can block the heat of cold transfer through aluminum. The raw material of polyamide strip is nylon and glass-fiber.

Thermal break aluminum profile assembling machine

The thermal barrier aluminum profile assembling machine is used for producing thermal brarrier aluminum profiles, including three sets of machines: one set of teeth forming machine with strip feeder, one set of rolling forming machine, one set of tester.

Thermal barrier aluminum profile production process


The production process for thermal barrier aluminum profiles is following


Load Aluminum profile on the working platform →film sticking →teeth forming→ strip feeding→ rolling→ or feed polyurethane foam into the insulation chamber→ packaging


1  The first process is to test the surface quality and dimension tolerance of aluminum profile, inner and outer aluminum profile can be anodizing or electrostatic powder coated treatment,  also can be different color. Through the thermal bridge connection, the inside and outside two colors aluminum window and doors can be got.


2 The second process is stick protective film. The main function is to protect the surface quality of aluminum profile in the processing and moving.


3 The teeth forming is key process, make two inner walls of aluminum profiles rolled for jagged teeth. Feed the strip into the teeth channel of aluminum profile, fasten them together.


Teeth channel depth is not specified in Domestic market. But in the industry standard GB/T building thermal break aluminum alloy standard, there is specification for the tensile strength and shear strength.


4 Strip feeding and rolling processes are important process. Strip feeding is to feed EPDM strip into the teeth channel of aluminum profile. Then through the rolling machine, make the aluminum extrusion profiles and Ethylene-Propylene-Diene Monomer o other materials strip rolled together


5 The process of feeding PU foam into insulation chamber is for foam thermal break aluminum profile. Put aluminum profile into the two group metering mixer; pour the PU foam into the insulated cavity of aluminum profile for the natural foaming by mixing nozzle.


PU is the polyurethane for short, whose thermal conductivity is very low. It has super acoustical property, electrical property and chemical resistance property. The foam insulated aluminum profile had the double insulation effect and it is suitable for cold area.


6 Packaging is final process, can be packed by plastic bag or wrapping packaging by paper.  The main function is to avoid the damage and scratch in the transportation and processing.
