Product Description

Extrusion Grade PA66 GF25 Thermal Break Polyamide Profiles Used for Heat Broken Bridge Aluminum Windows and Doors
Product Introduction
The polyamide strip is a mouldable composite material. Its fibers are oriented in all three dimensions to ensure appropriate strength. As such, manufacturers can use these strips across all types of fenestration, including oversized and impact-resistant systems. Therefore, polyamide thermal barriers are the best for thermal break windows.
Thermal break strip, also called heat insulation strip, is a part of aluminum bridge profile. The heat-insulating bridge aluminum-plastic profile can realize the three-way sealing structure of doors and windows, and reasonably separate the water vapor chamber. It successfully realizes the pressure equalization of gas and water, and significantly improves the watertightness and airtightness of the doors and windows.

Broken Bridge aluminum thermal break strip is an important criterion for distinguishing aluminum alloy doors and windows and broken bridge aluminum doors and windows.It is precisely because of the appearance of broken aluminum thermal break strips that the aluminum doors and windows of the broken bridge have good thermal insulation and sound insulation performance. The extruding high precision polyamide thermal break strip is used in windows and doors.Inserted in the thermal break aluminum profiles,it is the part of energy-saving window system for reducing heat sonduction.

The Function of Thermal Break Windows
1. Broken bridge aluminum thermal break strips reduce heat conduction: the heat broken bridge aluminum alloy profiles are adopted, and the hollow glass structure is adopted. The broken bridge aluminum doors and windows reduce the heat conduction through the doors and windows. In this way, it will not feel hot under the high temperature of the scorching sun in summer. It's cold and windy in winter, and we don't feel cold. This ensures that the indoor temperature is maintained.
2. Prevent condensation: The temperature of the inner surface of the broken bridge aluminum door and window profile with thermal break strips is close to the indoor temperature, reducing the possibility of indoor moisture condensing on the surface of the profile due to supersaturation. This is crucial for the insulation of the window.
3. The broken bridge aluminum thermal break strip plays the role of heat preservation and energy saving. Broken bridge aluminum door and window frames with thermal insulation strips can reduce the heat loss through the window frames by one-third. In summer, if there is an air conditioner, window frames with thermal insulation strips can reduce energy loss more.
4. To protect the environment: through the application of the thermal insulation system of broken bridge aluminum doors and windows, energy consumption can be reduced, and the environmental radiation caused by air conditioning and heating can be reduced at the same time.
5. Broken bridge aluminum thermal break strips are good for health: the heat exchange between the human body and the environment depends on the indoor air temperature, air flow speed and outdoor air temperature. By adjusting the indoor temperature of broken bridge aluminum doors and windows, the use is lower than 12~13 ºC, and the most comfortable environment has been achieved.
6. Broken bridge aluminum thermal break strips reduce noise: the use of hollow glass structures with different thicknesses and heat-insulated bridge-broken aluminum profile cavity structures can effectively reduce the resonance effect of sound waves, organize sound transmission, and reduce noise by more than 30dB.
