Insulating Bar Advantages:

Tianjin Ruifeng insulating bars are composed of 65% nylon (PA66) and 25% glass fiber (GF), black in color. As the main heat insulation component, they are suitable for aluminum alloy doors and windows, framed curtain walls, and play a decisive role in the three main performances of doors and windows: wind pressure resistance, water tightness, and airtightness.

Product Advantages are as follows:

1. Using cold extrusion technology, glass fibers are uniformly distributed in multiple directions, resulting in high strength and meeting design requirements to ensure the stability of heat-insulating aluminum alloy doors and windows and framed curtain walls. 
2. The coefficient of linear expansion is close to that of aluminum profiles, ensuring that under conditions of strong sunlight and severe cold, the insulating strip and aluminum material remain tightly bonded, without displacement or falling off. 
3. Processing temperature up to 235 degrees, fully meeting the process operation of inserting the strip before spraying.
4. Dimensional accuracy is less than 0.05mm. High dimensional accuracy facilitates serrated rolling processing and ensures the airtightness, water tightness, and wind pressure resistance of doors and windows and curtain walls. 
5. Excellent machining performance allows for secure fastening of hardware. 
6. Features fire resistance, high temperature resistance, chemical corrosion resistance, anti-aging, and UV resistance, making it more environmentally friendly and energy-efficient, with a longer service life and recyclability. 
7. Unique formula and special heat stabilizers ensure good quality of the insulating strip.

Product Performance:

● Improved comfort: The heat exchange between the human body and the environment depends on the temperature, flow rate of indoor air, and outdoor air temperature. Therefore, through insulating profiles, the temperature of the door and window surface is adjusted so that it is not lower than 12-13℃ to achieve the most comfortable environment for the human body.
● Environmental protection: Through the use of the heat insulation system, energy consumption can be reduced, reducing the use of air conditioners and environmental pollution.
● Condensation prevention: Appropriate system design will make the inner surface temperature of the insulating profile close to the indoor temperature, thus greatly reducing the possibility of indoor supersaturated water vapor condensing on the inner surface of the profile.
● Energy Saving
　--Reduces heat loss outdoors in winter, lowering heating energy consumption;
　--Reduces heat transfer indoors in summer, lowering cooling energy consumption;
● Sound insulation: Appropriately reduces noise pollution.

Instructions for Use: 
Insulating strips made of polyamide have a certain water absorption capacity. The speed and amount of water absorption depend on the following factors:

● Ambient temperature
● Ambient humidity
● Storage conditions

In summer, the temperature and humidity in the warehouse are relatively high, and the insulating strips will absorb more water than in other seasons, so they should be stored for a short time. Therefore, we recommend that the insulating strips should be stored indoors at a temperature of 15-20 degrees. When single bundles of insulating strips are moved from the shelf, they may be twisted and deformed. If not straightened in time, permanent twisting and deformation will occur. Therefore, we recommend minimizing the bending degree of the insulating strips during storage. To prevent twisting and bending deformation, please try to shorten the storage time before processing. If you have any specific questions, please contact us, we are happy to provide you with relevant services.

We have a professional export team and our brushes are exported to European and American countries. We can do OEM and ODM services. We have a brush design team that develops and designs new brushes every year.
