Which Type of Sealing Strip Is Best for Doors and Windows?

Sealing strips, a critical component of door and window systems, are primarily installed in key areas like frames, sashes, and glass panels to perform multiple functions such as sealing, waterproofing, sound insulation, shock absorption, and thermal insulation. This demands that sealing strips possess excellent tensile strength, elasticity, temperature resistance, and aging resistance to ensure seamless compatibility with door/window profiles and achieve optimal sealing. However, with so many types of sealing strips on the market, which one is most suitable for your needs? Let’s explore the key factors.  

1. Material  

Common sealing strip materials include rubber, silicone, and PVC:  

- Rubber: Offers good elasticity and temperature resistance but relatively weaker aging resistance.  

- Silicone: Excels in high-temperature tolerance and durability but comes at a higher cost.  

- PVC: Budget-friendly but less elastic and heat-resistant.  

Choose based on your door/window environment and budget.

2. Installation Method & Compression Range  

Different installation methods require specific cross-sectional shapes and sizes for the strips. The compression range (how much the strip deforms when the door/window closes) directly impacts sealing performance. Ensure the strip’s design aligns with your door/window profile for maximum effectiveness.  

3. Compressive Force  

Proper compressive force ensures tight contact when doors/windows close, effectively blocking air, moisture, and noise. However, excessive force may deform or damage the strip, shortening its lifespan.  

When selecting sealing strips, balance material properties, installation requirements, compression range, and force tolerance. A scientific, tailored choice will guarantee both sealing performance and long-term durability for your doors and windows.
