Insulating Bar Advantages:

Tianjin Ruifeng insulating bars are composed of 65% nylon (PA66) and 25% glass fiber (GF), with a black 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 performance aspects 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 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 the insulating bar and aluminum material remain tightly bonded under conditions of intense sunlight and severe cold, without displacement or detachment. 
3. The processing temperature is as high as 220 degrees, fully meeting the process requirements of pre-insertion and post-spraying.
4. Dimensional accuracy is less than 0.05mm. High dimensional accuracy facilitates the opening and rolling process and ensures the airtightness, water tightness, and wind pressure resistance of doors and windows and curtain walls. 
5. Excellent machining performance, suitable for fastening hardware. 
6. It has fire resistance, high temperature resistance, chemical corrosion resistance, anti-aging, anti-ultraviolet and other functions, making it more environmentally friendly and energy-efficient, with a longer service life and recyclability. 
7. Unique formula and special heat stabilizers ensure the good quality of the insulating bar.

Product Performance:

● Improve comfort: 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 to no less than 12-13℃ to achieve the most comfortable environment for the human body.
● Protect the environment: Through the use of insulation systems, energy consumption can be reduced, reducing the use of air conditioning and environmental pollution.
● Prevent condensation: Appropriate system design will make the inner surface temperature of the insulating profile close to the indoor temperature, thereby greatly reducing the possibility of indoor supersaturated water vapor condensing on the inner surface of the profile.
● Energy saving
　--Reduce heat loss to the outdoors in winter and reduce heating energy consumption;
　--Reduce heat transfer indoors in summer and reduce cooling energy consumption;
● Sound insulation: Appropriately reduce noise pollution.

Instructions for Use: 
Insulating bars 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 bars will absorb more water than in other seasons, so they should be stored for a short period. Therefore, we recommend that insulating bars should be stored indoors at a temperature of 15-20 degrees. When single bundles of insulating bars are moved from the shelves, they may be twisted and deformed. If they are not straightened in time, permanent twisting and deformation will occur. Therefore, we recommend that the degree of bending of the insulating bars be minimized during storage. To prevent twisting and bending deformation, please try to shorten the storage time of pre-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.
