The need for noise control

Urbanization forces people to live close together.

Noise pollution reduces mental concentration and affects health.

Ballistic ResistanceAnti-Intrusion Glazing

SentryGlas®, Trosifol® &

Spallshield® can meet ballistics-

resistance test standards in

constructions that are lighter-

weight, thinner and more

durable

Used where resistance to bullet

penetration and spall is

desirable:

- Residential buildings

- Government/public

buildings

- Armoured vehicles

Security and protection against

terrorist attacks, vandalism and

thefts

Most common standards for

security testing and glazing

- Anti-Intrusion Glass

- Bullet–Resistant Glass

- Blast-Resistant Glass

Blast Performance

LSG can be designed for blast-

resistance, to help let in light &

keep out trouble

Blast-resistant glazing can be

used to reduce the hazards

associated with an explosion

Add Spallshield® CPET for a final

layer of ballistic protection

Bullet Resistant Glass

• Composite laminates

comprised of multiple plies

of glass and both PVB and

ionoplast interlayers

• Testing done for most levels

of ballistics threats
