GLASS

Low E Glass
The buzz phrase pulsing through the glazing industry right now is Low E, and it’s now available for auto applications. It has been designed to reduce energy transmission through glass to improve thermal comfort inside the vehicle.

Low E (Low emissivity) glass has silver and metal oxide layers on the glass surface. Its major function is to lower the U-value and selectively lower the shading coefficient (SC), which on the whole improves the energy efficiency of the glass. It features high infrared reflection and because of its low surface emissivity, it absorbs and re-radiates very little energy.

The science behind this process is complex, and its complexity is what makes it so effective. Put simply, Low E glass works in any temperature to help keep heat out during hot days and heat in on the cooler days.

Acoustic
A special resin layer in the PVB of the glass is used to reduce noise coming through the windows. A comfortable acoustic cabin environment is attained without increasing the weight or thickness of the glass.

HUD (head-up display)
Advances have been made in the development of head-up display (HUD), which is the projection of important information onto the windscreen. The information appears in the driver’s line of sight without diminishing vision of the road or external environment. 

HUD prevents the driver’s need to turn focus away from the road to check speed, KMs travelled, petrol status, etc.

Please note that at present, HUD windscreen can only be obtained from the OE maker.

DIRECT GLAZING ADHESIVES
Significant changes have occurred in recent years regarding direct glazing adhesives, namely:

  • They must meet new requirements regarding:
    1. Electrical conductivity/resistance (aluminium bodies/rear window heaters) 
    2. Radio frequency performance (integrated car antennas)
    3. Shear modulus (light-weight body designs)
  • Specification of a European NCAP Crash test standard equals more stringent passive safety requirements
