OEM vs. Aftermarket:

When it matters, when it doesn't

First things first: what is OEM and what does it mean? OEM stands for Original Equipment Manufacturer. When you are talking about the glass itself, OEM simply means that the glass being installed is manufactured by the same manufacturer as the glass that was originally installed at the factory. Generally speaking, the biggest difference between OEM glass and the aftermarket glass we use at Professional Glass is the "dealer" label on the glass. In all other aspects, aftermarket glass is designed to fit specifically in the vehicle it is manufactured for. Further, whether it is OEM or aftermarket glass, each windshield installed in the United States must meet the designated standards as set by the Federal Motor Vehicle Safety Standards. We choose top-quality aftermarket glass, and you can be certain that the glass we install is the same quality and apperance as the glass we take out of your vehicle. It is the same strength and will resist rock chips and other damage at the same rate as OEM glass.

​

However, OEM means something entirely different when we are talking about the adhesives and sealants used to install the new windshield. When it comes down to it, glass is glass is glass, especially when it all has to meet the same FMVSS requirements. But not all adhesives are created equal! As mentioned elsewhere on our website, your safety is our highest priority. Therefore, we ONLY use manufacturer-approved OEM sealants from Sika Adhesives. Further, we participate in the annual certification process Sika and AGRSS provide, so our customers know that our installers are all certified and up-to-date with the lastest technologies and safest installation techniques.
