What does underside glass molding do?
Underside glass molding seats between the bottom edge of the glass and the vehicle's pinch weld or channel. It provides a consistent seal, cushions the glass against the body, and prevents direct metal-to-glass contact. It also helps exterior trim and moulding sit flush around the glass opening after installation.
Why is 7mm such a common width?
7mm balances the narrow profiles (5mm) needed for compact cars with the wider profiles (9–10mm) needed for trucks and SUVs. Most mid-size sedans, crossovers, and minivans — domestic and import — use a 7mm underside profile, making it the go-to shop stock width for general windshield work.
What is the difference between EPDM sponge and solid compound molding?
EPDM sponge compresses under pressure, making it forgiving in channels with slight dimensional variation and easy to run around bends and corners. Solid compound holds its dimension without compressing — better when the channel measurement closely matches the molding width and a rigid profile is preferred. Both bond to the glass via pre-applied tape.
How much molding do I need per installation?
A typical passenger vehicle windshield requires 12–16 feet of underside molding. A 100-foot roll covers approximately 6–8 complete installations. The 75-foot roll (PRM07USMF) is available for shops with lighter usage or limited storage.
Is this compatible with both OEM and aftermarket glass?
Yes — this molding is cut to length on-site and works with both OEM and aftermarket replacement glass. Always verify the channel dimension on the specific glass being installed, as aftermarket profiles can vary slightly from OEM.
