How to install door and window sealing strips? What should I pay attention to?

Door and window sealing strips are commonly black rubber materials, commonly found at the edges of doors and windows. They are elastic strip or rod like materials at the joints between glass and pressure strips, glass and frame sashes, frames and sashes, and between sashes. It can block water, wind, sound, and temperature, and prevent mechanical damage caused by metal collisions, thus achieving sealing, sound insulation, heat insulation, and shock absorption.

Therefore, as a key component of doors and windows, it must have sufficient tensile strength, good elasticity, good temperature resistance, and aging resistance to ensure a good user experience and comfortable home experience. Therefore, its cross-sectional structural dimensions should not only match the door and window profiles, but also have sufficient strength and durability.

Therefore, the quality of door and window sealing strips determines the quality of a window, and many doors and windows make great efforts to use sealing strips in this regard.

How to distinguish the authenticity of sealing strips?

It is quite easy to distinguish the authenticity of sealing strips. The following methods can help you identify the quality of sealing strips without the need for tools.

1. First, smell with your nose to see if there is any odor. Normal sealing strips do not have any odor, or if there is a natural rubber smell when the steel leaves the factory.

2. Wrap the sealing strip tightly around the profile and expose it to sunlight for a period of time to see if there are any stains or dirt adhering to the profile. Check if the surface of the sealing strip turns yellow and if there are any oil stains attached.

If the cross-section of the rubber strip is bright and similar in color to the surface, it indicates that there is not too much filling material.

4. Hold the rubber strip in your hand and stretch it forcefully. If it is not easy to break and the stretching degree is good, it means that the quality is good and it will not deform after long-term use.

5. Use your nails to scrape the sealing strip. If the material quality is poor, it is easy to produce white color. This type of sealing strip cannot withstand collisions. Once there is a hard object impact or scratch, the sealing strip will lose its appearance.
