SGP Sentryglass
Dupont SGP Sentryglass SUPPLIED BY CLEAR GLASS SOLUTIONS: Clear Glass Solutions supply this glass in its manufacturers name SGP Sentryglass.
Our SGP glass is a toughened laminate glass where the laminate can be exposed to the weather and it does NOT need to be framed. SGP Sentryglass is 5 times stronger then normal PVB interlayers and is rated for cyclonic and high wind conditions. This glass is the ideal solution for glass balustrades, shop fronts and building facades where a stronger barrier is required for protection and strength amongst other reasons.
What are the Architectural Glass Benefits when using DuPont™ SentryGlas®?
- Clearly Safer: DuPont™ SentryGlas® in Architectural Glass is five times stronger and up to 100 times stiffer than conventional laminating materials.
- DuPont™ SentryGlas® interlayers help create glass that protects against bigger storms, harder impacts and heavier loads. This is cyclone and hurricane rated glass!
- In Australia a handrail is generally required for glass balustrades, however NO handrail is required for glass balustrades where SGP glass is used. Engineering is required according to the glass support systems to be used.
- SGP is the Ideal toughened laminate or heat strengthened laminate for glass canopies, glass roofs and facade systems.
- SGP is the ideal laminate for security doors and windows.
Benefits at a glance
- Safety: In the event of breakage, glass fragments remain firmly bonded to the interlayer, reducing the chance for injury.
- Security: SentryGlas® can be used in glazing that withstands bullets, hurricane-force winds and even bomb blasts.
- Solar energy control: SentryGlas® can be used with coated low-E glass for improved energy efficiency. It can also help engineer more effective thermally insulated glass, and glass with better controlled (or allowed) transmittance of V radiation.
- Durability: SentryGlas® is extremely durable and resistant to clouding, even after years of exposure.
- Design Versatility: SentryGlas® can be used in glass manufactured flat or curved, including annealed, toughened, heat-strengthened, spandrel, wired, patterned and color tinted glass.
SentryGlas® is strength!
Since the interlayers are an engineered component within the glass, they serve as a more active structural element in the building envelope. This extra strength increases design freedom.
Exposed laminate edges. The SGP interlayer is weather tolerant!
DuPont™ SentryGlas® offers long-term durability even when edges are exposed to weather. Open edges of glass made with SentryGlas® are less susceptible to moisture intrusion, and remain free from clouding even after years of service. Resulting laminates handle higher structural loads than PVB, making SentryGlas an excellent choice for balustrades and minimally framed or point-supported facades.
Wind and impact protection
Because SentryGlas® is stiffer and tougher than conventional interlayers, it can withstand higher winds and greater impacts from wind-borne debris. Building owners can opt for SentryGlas® over storm shutter systems, and boost protection for essential facilities.
DuPont introduces new, thinner SentryGlas®
DuPont Glass Laminating Solutions announces commercial availability of new 0.9-mm (35-mil) DuPont™ SentryGlas® clear interlayer for use in making strong, protective windows, doors and safety-glazed building elements.

In contrast to PVB, all three thicknesses of DuPont™ SentryGlas® interlayers significantly improve the load resistance of laminated safety glass.
Originally launched in 1.52- and 2.28-mm (60- and 90-mil) thicknesses, DuPont™ SentryGlas® immediately helped architects and engineers meet toughened building codes in areas such as Florida, subject to hurricane-level destructive forces.
Because SentryGlas® is 100 times stiffer than traditional polyvinyl butyral (PVB) interlayers, it also finds use in higher-performing structural laminated glass, such as in railings, stairs, floors and advanced facade designs.
“Adding a thinner SentryGlas® helps us expand the range of applications we can serve,” said Hayati Yarkadas, DuPont global business director for advanced interlayers. “Beyond storms, people worry about intruders, home safety and health, and energy-efficient living; SentryGlas® can make a big difference in all these areas.”
The markets for thinner SentryGlas® sheets include solar power generation, where clean energy production can be made more cost-effective through the design of longer-lasting, lighter-weight modules.
Less is more
Five times tougher than conventional PVB interlayers, ionomer-based SentryGlas® is also 10 percent lighter in density, more resistant to moisture, and less susceptible to edge defects after lamination. Combined, these advantages can help architects create lighter, brighter, larger open spaces. Engineers can design stronger, more durable, more protective building elements such as skylights, rails, stairs, doors, storefronts and open-edged glazing.
“Laminators and window companies wanted a thinner grade of SentryGlas®, to help replace thicker constructions using PVB,” explains Yarkadas. “They report that more and more architects and engineers are asking for SentryGlas®, and looking for thinner choices to meet a wider range of protection needs.”
DuPont™ SentryGlas® 0.9 mm interlayer sheets are available to laminators worldwide. For more information, visit sentryglas.com.
