Sometimes, windshield replacement is something you can plan for — other times, it’s unavoidable after unexpected damage from road debris like stones, pebbles, or even birds. When that happens, it’s important to know your options. If you’re getting ready for a windshield replacement, you’ll typically have two choices: OEM (Original Equipment Manufacturer) glass or aftermarket (OEE) glass. Understanding the difference between the two can help you make the best decision for your vehicle’s safety, fit, and budget — and we’re here to walk you through it.
What Is OEM Auto Glass?
OEM (Original Equipment Manufacturer) auto glass is made by companies that are officially licensed by automakers. These manufacturers produce glass that adheres to the exact specifications of the vehicle’s original design. OEM glass matches the original in terms of thickness, shape, tint, and overall fit. Additionally, OEM windshields may carry the carmaker’s logo, ensuring it meets the automaker’s standards for quality and safety.
What Is Aftermarket Auto Glass?
Aftermarket, or OEE (Original Equipment Equivalent) auto glass, is produced by manufacturers who do not have a direct partnership with the automaker. As a result, aftermarket glass is not an exact replica of the original windshield, and it cannot carry the vehicle manufacturer’s branding. While it is designed to fit the vehicle, there may be slight differences in thickness, tint, or shape compared to OEM glass
Key Differences Between OEM and Aftermarket Glass
When helping your customers decide between OEM and aftermarket auto glass, there are several factors they should consider. Here’s a breakdown of the key differences between the two options:
Quality and Safety
- OEM glass is produced according to the specific standards set by the automaker. As a result, it is considered to be the highest-quality option for windshield replacement. The safety, fit, and finish of OEM glass are identical to the original windshield that came with the vehicle. On the other hand, aftermarket glass meets the minimum safety requirements established by the Department of Transportation. While it is still safe to use, aftermarket glass may not meet the same high standards as OEM glass in terms of durability and performance.
Availability
- For vehicle owners with older models or less common cars, finding OEM glass can be difficult, as it may no longer be readily available. In such cases, aftermarket glass often presents an easier solution, as there are more manufacturers producing a wide variety of glass products for different vehicle makes and models. Aftermarket glass is often more readily available, especially for older cars or models with limited production.
Final Thoughts: Making the Right Choice
When a customer asks for advice on which type of glass is best for their windshield replacement, it’s important to consider the pros and cons of both OEM and aftermarket options. Factors such as quality, cost, availability, and insurance coverage will all influence their decision. As an expert in the field, you can help guide them toward the best choice based on their preferences, budget, and needs.
