What Is Windshield Molding and What Does It Do?
So what is been windshield molding? Windshield molding is a kind of trim made of rubber or plastic that extends around the edges of a vehicle’s windshield. Modern automotive windshields are held in place by a strong adhesive (urethane) which bonds the windshield to the frame. The trim doesn’t hold the glass in place it rests on the adhesive to protect it and seal the edges.
This trim helps;
- Prevent water leaks
- Reduce wind noise
- Protect the adhesive from sun damage
- Enhance the overall look of the vehicle
Chronic water infiltration results in frame rust and interior damage and windshield molding is an integral part in preventing that from occurring.

- Adhesive molding is bonded to the surface of the glass or body, offering a more seamless look but making it more difficult to remove.
Locking Strip Molding (Older Vehicles)
Some older models may have a windshield lock strip molding, with a metal strip that ensures the windshield stays in place. Most of this type must be cut out all at once.
Why Windshield Trim Is So Important
Windshield trim is way more than just a cosmetic enhancement.
Prevents Water Damage
Rainwater can penetrate tiny holes. In the absence of proper weatherstripping, water could get in the frame, which causes rust and can eventually lead to structural failure.
Reduces Wind Noise
Some homes benefit from missing or loose weatherstripping catching air under panes of glass, resulting in annoying whistles particularly at the highway speeds.
Protects the Adhesive
Sunlight, dirt and water can slowly break down the waterproof adhesive that holds your windshield to your car. The windshield molding shields the adhesive so the windshield will remain bonded tightly.
