Frequently Asked Questions (FAQ) on Window Weather Stripping & Technical Terms
Q1: What is the optimal durometer for automotive and window weather stripping?
A1: Most high-quality car weather stripping use 60±5 Shore A. This hardness balances flexibility and long-term compression recovery, critical for door/window sealing.
Q2: What does compression set mean, and why is it important?
A2: Compression set refers to a material's ability to return to its original thickness after prolonged compression (e.g., when a car door is closed). A low compression set (≤20–25%) ensures the weather stripping keeps a tight seal over many years.
Q3: What are common industry standards for weather stripping?
A3: Leading standards include ISO 9001, ISO 9227 (salt spray), ASTM D395 (compression set), ASTM D412 (tensile), ANSI Z94.6 (QC). Meeting these ensures product durability, safety, and reliability.
Q4: What’s the best way to install weather stripping door bottom for maximum durability?
A4: Use a degreased, dry surface, apply even pressure for adhesive types, and avoid overstretching. Fastening clips should match the door’s material; professional installation prolongs service life.
Q5: Can window weather stripping be used for industrial sealing (e.g., chemical plants)?
A5: Yes; by specifying EPDM or custom blends (per ASTM D2000), with higher chemical and ozone resistance, window weather stripping can seal hatches, manways, and process windows in harsh environments.
Q6: What is glass run channel in automotive weather stripping?
A6: It’s a U-shaped sealing profile lining the window perimeter, providing a smooth track for sliding glass while blocking water, dust, and noise.
Q7: How is quality assured during production?
A7: Each batch undergoes dimensional, hardness, compression, and water-leakage testing under ISO/ASTM protocols; random samples are aged in UV and salt-fog chambers before approval.
Summary: Why Choose Modern Window Weather Stripping?
  • Delivers energy savings, moisture and dust protection, and extended operational life across automotive and building sectors.
  • High customization and adaptability for every application, from window weather stripping to complete auto weather stripping overhaul.
