Mountainside Glass uses only manufacturer approved replacement glass and parts. These are referred to as OEM. OEM stands for Original Equipment Manufacturer. An OEM part will have identical details such as rain sensors, dot matrix patterns, heating elements, heads up display, shading, and third visor frit bands. These OEM windshields carry names such as PPG, Pilkington, Sekurit, ULN, APTech, Carlite, Guardian and several other names. These are the very same makers of the glass when you bought it straight off the lot. We use these parts for superior fit and for warranty purposes as well.
