FR4 (FR = Flame Retardent)is a glass fiber epoxy laminate. It is the most commonly used PCB material. 1.60 mm (0.062inch). FR4 uses 8 layers glass fiber material. The maximum ambient temperature is between 120o and 130oC, depending on thickness.
FR4 (single layer): copper foil + glass fiber fabric
FR4 (double layer): copper foil + glass fiber fabric + copper foil
