WHAT THE FUTURE HOLDS FROM THE OEM SIDE OF
THE BUSINESS1. Size
Windshields and Roofs have had a trend in which size has been growing.• We are seeing windshields that are exceeding 2.5 square meters in size
• There are challenges relating to optics, bending , solar load, weight
• Larger windshields mean larger A zones. Large windshields can be sag bent, but should be pressed for better optics.
• With larger windshields comes more complex shapes, meaning more pressing
• Larger windshields allow more energy into the cabin. Solar countermeasures are becoming required.
• Tts, what is it? TL, what is the requirement?
• Solar reflective coatings, PET vs Coated.
• The first 4.0mm windshields are here
• 1.8/1.4 Asymmetric vs symmetric 1.6/1.6
• Alfa 4C, BMW I3 and I8(which is also HUD)
• 3.0mm ?
• Roofs are also growing in size and content.
• Solar efficiency is a growing topic in the OEM’s
• With more glass in the roof, it is becoming uncomfortable for the passengers.
• Glass is going darker and with more solar countermeasures.
• 20% or less Tts can be achieved with Low E coatings
• Glass is heavy
• Larger glass roofs pose a problem for already top-heavy SUV’s
• 5mm tempered to 4mm laminated
• Safety
• There is a lot of discussion around the shower of glass when a tempered piece is broken
• Tempered pieces become more fragile with more blackout.
• The move to laminated.
1. SIZE
2. ELECTRONIC CONTENT
The content incorporated into and on windshields have a very steep curve in the coming years.
• Sensors
• Individual or sensor farms, the alignment to the glass and normal to X and Y are critical, as well as distortion in the glass and TL(Transmitted Light)
• Pressing ensures that the surface to nominal is usually within +/- 1.0mm
• IRR coatings may require windows in the reflective film.
• Autonomy
• More cameras (sometimes 2 or three), possible radar. Backlite?
• Information
• Head Up Display
• Windshield must be pressed to maintain
surface to nominal within +/- 1.0mm
• Display size is growing, more colors.
• HUD suppliers now have three different
types of systems.
• There is development ongoing for displays
integrated inside the glass layers.
3. MATERIALSThere has been a lot of talk about using chemically tempered glass, like on smart phones.
• Common glass is soda lime based, tablet type glass is aluminosilicate composition, or an alkali-aluminosilicate glass
• Chemically Tempered means that there is an Ion Exchange due to a chemical bath as opposed to heat tempering.
• In automotive applications it is usually a .7mm thickness. Compositions discussed have been .7/.7, and hybrids consisting of an outer glass of soda lime and an inner of chemically tempered.
• Very difficult to process, and very expensive.
• Will it remain a science project or become mainstream?
• PVB’s can be standard, Acoustic, wedged for HUD, and PET layered.
• Expect Acoustic upgrades
• Expect HUD upgrades.

WHAT WE CURRENTLY KNOW
• Re-calibration requirements
• GM (Self-calibrating)
• All others (Dealer involvement)
• Costs
• Options
• Dealers
• Private vendors
WHAT COULD THESE CHANGES
DO TO OUR INDUSTRY?
• Our Issues
• Body mounted
• Distortion
• Curvature
• Mounting brackets
• Glass mounted
• Mounting brackets
• OEM Glass
WHAT COULD THESE CHANGES
DO TO OUR INDUSTRY?
• Dealer issues
• Can a dealer even handle the demand for recalibration?
• Can a dealer stock enough glass inventory?
