All windscreens in vehicles manufactured in the last 20 years are made with laminated glass. Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking your BMW X4 Windscreen, it will be held in place by an interlayer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the BMW X4 glass from breaking up into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. In the case of the EVA, the thermoset EVA offers a complete bounding (cross-linking) with the material whether it is glass, polycarbonate, PET, or other types of products.
Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered and also for architectural applications. Skylight glazing and automobile windshields typically use laminated glass. In geographical areas requiring hurricane-resistant construction, laminated glass is often used in exterior storefronts, curtain walls, and windows.
Laminated glass is also used to increase the sound insulation rating of a window, this was first invented when diesel became popular due to louder engine noise, it significantly improves sound attenuation compared to monolithic glass panels of the same thickness. For this purpose, a special "acoustic PVB" compound is used for the interlayer. In the case of the EVA material, no additional acoustic material is required, since the EVA provides sound insulation. An additional property of laminated glass for windows is that a PVB and EVA interlayer can block essentially most ultraviolet radiation. A thermoset EVA could block up to 99.9% of all UV rays.
The heated rear window on your BMW X4 is made in a similar way to the side windows on your BMW X4, its a toughened piece of glass but with antennas for radio and GPS and heated connections installed also, this is why heated rear windows are generally quite expensive compared to most other car glass, although they are fitted in the same manner as the front windscreen. Just like side windows we also remove the panel in the boot and vacuum as much glass as we can out, along with any glass that may have entered your vehicle in the boot space and rear seats.
