[2026 Update]
Arizona’s dry, sunny climate and rocky desert freeways wreak havoc on automotive glass. If you drive anywhere in the Phoenix Metro area, it’s not a matter of if you will get a rock chip, but when.
Extreme summer heat compromises your windshield’s integrity. When a vehicle in 115°F heat uses air conditioning, the glass suffers “thermal shock” from the temperature extremes. This process weakens all windshield types, causing minor chips to rapidly expand into large cracks that obstruct your vision.
But when your auto glass breaks, what are your options? Understanding the different types of windshield glass, how they are engineered, and the differences between factory and aftermarket options can save you time, money, and hassle.
The Types of Automotive Glass
Modern vehicles utilize two entirely distinct safety glass technologies engineered for specific structural roles:
Laminated Glass (Your Windshield)
Laminated glass is a three-layer sandwich consisting of two sheets of glass fused together by a clear, flexible inner layer of Polyvinyl Butyral (PVB).
This model guarantees that even in case of a crash, it’s not going to shatter inwards and cause more harm than good.
Tempered Glass (Side & Rear Windows)
Tempered glass is a single sheet of glass heated to extreme temperatures and then rapidly cooled with high-pressure air blasts. This process makes it up to four times stronger than standard glass.
Premium modern electric vehicles, including many Tesla models, have begun utilizing laminated glass on passenger side windows as well to reduce cabin noise and improve security.
OEM vs. Aftermarket (OEE) Windshield Glass: Which is Better?
When getting your glass replaced, you will typically be offered two choices regarding the manufacturing source of your new glass:
OEM (Original Equipment Manufacturer) Glass
Manufactured by the exact same company that produced the glass original to your vehicle. It features identical sizing, thickness, tinting, and branding logos.
When Should You Choose OEM Glass?
- Your car features advanced safety tech: Essential for modern vehicles and electric vehicles (like Teslas) with forward-facing ADAS cameras, lane-keep assist, or Heads-Up Displays (HUD) to prevent visual distortion.
- You drive a newer or leased vehicle: Protects your vehicle’s factory warranty and satisfies strict lease-return inspection criteria.
- You are using Arizona full glass insurance: If your policy includes zero-deductible coverage under ARS §20-264, insurance will usually cover factory-original glass for modern, tech-heavy cars at $0 out of pocket.
OEE / Aftermarket (Original Equipment Equivalent) Glass
Manufactured by a third-party company. While meeting safety standards, it may have slight variations in solar tint thickness or exact curvature tolerances.
When Should You Choose Aftermarket (OEE) Glass?
- Your car is an older model: If your vehicle does not have complex sensors, smart cameras, or rain-sensing wipers, premium aftermarket glass offers identical structural safety.
- You are paying out of pocket (cash): If you don’t carry full glass insurance, high-quality aftermarket glass is significantly more affordable and budget-friendly.
- You need an immediate installation: Factory supply chains can cause long backorders for OEM glass. Aftermarket alternatives are highly accessible, eliminating long wait times so you can drive safely sooner.
