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 –Resisting Glass
- Blast-Resisting 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

32. What is Structural Glazing?
Examples of Structural Glazing
 Balustrades
 Overhead & Canopies
 Floors & Stairs
 Large Windows
 Curtain Walls
 Fins, screens and louvers
 Point-fixed systems, open edge systems
32

33. SentryGlas® Ionoplast Interlayer

 Available in both roll and sheet form (upto 3210mm wide)
 Caliper ranges from 0.76mm to 3.04mm
 Available in Ultra Clear and in Transluscent White
 Highest level of structural performance of any interlayer
 Excellent post breakage performance over a wide range of
temperatures
 Reduction of glass weight of up to 50% is possible
 High Clarity – Ideal for Low Iron UltraClear Glass
 Excellent Edge Stability and Sealant compatibility

35. Structural PVB : Trosifol® Extra Stiff (ES)
 Stiff PVB available in rolls of 0.76mm
thickness and upto Jumbo widths (3210mm)
 Excellent post breakage performance
temperatures at temperatures UPTO 30°C
 Maximum strength for minimum deflection
at minimum laminate thickness for
temperatures up to 30°C
 High Clarity- Best clarity of any PVB
 Lower cost than ionoplast interlayer

38. Trosifol® family of Structural Interlayers
38
SentryGlas® interlayer and Trosifol® ES interlayer are both high modulus stiff interlayers
which provide a range of performance to meet all of your structural glazing demands
SentryGlas® IonoplastTrosifol® Extra Stiff (ES)
• SentryGlas® is specified in the
application because of its unique
properties
• Application requires the highest
structural performance over a wide
temperature range
• Open edge applications or sealant
compatibility
• Thinner glass construction is highly
possible
• Open Edge Applications
• Application requires a structural
interlayer
• Design temperatures up to 30°C
• Lower cost may be possible
