Laminated & tempered auto glass
What it is
Windscreens are laminated - two glass layers bonded by a plastic interlayer that holds fragments together on impact; side and rear glass is tempered to shatter into blunt granules. Both are safety-mandated rather than optional
Newer vehicles add acoustic interlayers, solar control coatings and sensor and camera mounting for driver assistance
Impact on industries
- Safety regulation makes the product non-discretionary, and specification is set by the vehicle maker rather than by price
- Content per vehicle is rising with panoramic roofs, acoustic lamination and ADAS sensor integration in the windscreen
- OEM approval is slow and model-specific, so an incumbent supplier is difficult to displace mid-platform
- Demand tracks vehicle production, so it inherits the auto cycle without the aftermarket cushion that tyres and batteries enjoy
- Replacement demand exists through breakage and insurance claims, but it is small relative to OEM fitment
