Is it useful to add sealing strips to a sedan?
2 Answers
Adding sealing strips to a sedan is not useful: 1. The noise reduction effect is not significant, as the main sources of car noise are engine noise and tire noise; 2. Drainage holes may get blocked. There are several drainage holes at the bottom of the car doors, and installing sealing strips can easily block these holes. The consequence of blocked drainage holes is poor drainage, which may damage the power window motor of the rear doors. Sealing strips are products designed to seal something, making it difficult to open, and they serve functions such as shock absorption, waterproofing, noise insulation, heat insulation, dust prevention, and fixation. Sealing strips come in various materials, including rubber, paper, metal, and plastic.
I think adding sealing strips to sedans is very practical, especially for older cars whose door gaps have widened after several years of use. Having driven many vehicles, I've noticed that the declining sealing performance in older cars increases wind noise, making it difficult to hold conversations inside the car at high speeds due to the roaring sound. Installing sealing strips can significantly reduce noise while also preventing dust and water ingress, keeping the interior dry and comfortable during rainy days. The installation process is simple—I purchased materials online and did it myself, opting for high-quality rubber strips to avoid premature aging. Although the effectiveness varies by vehicle (newer cars may not notice much difference), it provides tangible benefits in improving driving quietness and daily maintenance at a low cost, making it worth trying. Some worry about affecting door operation, but with proper installation, there are no issues. It also reduces air conditioning energy loss, making summer drives cooler and more economical.
