WINDSHIELD
SOLUTIONS FOR VISIBILITY, SOLAR
AND ACOUSTIC COMFORT
Customer Needs
For safety and drivers’ comfort, a train driver needs
to have good perception of the environment, i.e.
good visibility and good perception of colours in all
climatic conditions as well as acoustic comfort.

S
aint-Gobain Sully’s Solution
In order to achieve the best comfort level for the driver,
Saint-Gobain Sully unifies following technologies:
1. Chemical treatment to obtain the
thinnest glass
With the chemical treatment resistance of glass
increases giving the possibility to use the thinner
glass and hence increase the visibility. The process of
chemical reinforcement is developed by Saint Gobain
and avoids the mechanical treatment on the glass
surface resulting in no deformation and no rolls, which
are characteristic to other reinforcement technologies.
3. Heating system for good visibility
Airplex® and Indiex®, two systems developed by SaintGobain, enable homogeneous heating on the entire
windshield surface. Both of them avoid the haze effect
on glass.
Either Airplex® - the heating system with wires - or
Indiex® - coating on the glass - is used depending on
the glass composition and Customer needs.

Bending is done using a special oven which heats the
glass above its transition temperature.
Finite Elements Analysis - a simulation tool developed
by Saint-Gobain is used to forecast the complexity
of shape and define the right tool with the right
temperature level.

4. Sun protection
For visibility comfort in sunny conditions, a special
layer is embedded in the glass composition on the top
side of the windshield to protect the driver from direct
sun exposure.
