Tempered and heat soaked laminated glass with SGP interlayer

1- Material:

SGP is abbreviation of Sentry Glass Plus Interlayer, crated by American brand Dupont, on June 1, 2014, Kuraray Co., Ltd. became the exclusive licensee for the technology and trademark of SentryGlas®.

PVB is Polyvinyl butyral, many different suppliers can produce this material all around the world.

2- Thickness: The PVB thickness is 0.38mm, 0.76mm, 1.14mm, multiple of 0.38mm, the SGP thickness is 0.89mm, 1.52mm, 2.28mm, 2.53mm, 3.04mm etc.

3- The main difference is “SGP” will stay standing when both sides are broken as compared to “PVB” it will fall down or break when both sides have become damaged. The SGP laminated glass is five times stronger and up to 100 times stiffer than PVB laminated glass. That’s why designers like to use SGP laminated glass for application which face to bad weather like ike storms, hurricane and cyclone, also for some place with war or need high security.

4- Clarity: The SGP yellow index is smaller than 1.5, while normally the PVB yellow index is 6-12, so the SGP laminated glass is much more clear than PVB laminated glass.

SGP & PVB glass makeup:

THE SGP INTERLAYER

The SGP interlayer is an important factor in ensuring our toughened laminated glass is the best it can be. It’s doesn’t just make it tougher and stronger, it makes our glass blast resistant – but without compromising on the appearance.

The DuPont Sentry Glass Plus (SGP) is composed of a tough plastic interlayer composite that is laminated between two layers of tempered glass.

It extends the performance of laminated glass beyond current technologies as the interlayer offers five times the tear strength and 100 times the rigidity of the more conventional PVB interlayer.

What makes the SGP interlayer so special?

• Greater security from threats such as severe weather
• Can withstand bomb blast performance requirements
• Greater durability in elevated temperatures
• Fragment retention
• Thinner and lighter than PVB

The SGP interlayer ensures glass is strong, tough and durable yet still light and thin making it extremely suited to today’s architectural demands.
