Stronger, Safer, and Clearer laminated glass solution


SGP (SentryGlas Plus) is another popular security interlayer used in laminated glass, with increased strength and security. 5x stronger than traditional laminated glass, tolerates high-stress loads, reducing the need for additional supports. Moisture-resistant, eliminating the need for edge framing. UV-resistant, eliminating any fear of a cloudy or yellowing interlayer. Thinner, larger panels of SGP still absorb more impact than other options. It may come with a slightly larger price tag, but given its strength, durability, and visual consistency, the added value far outweighs the cost.

everything you may want to know about SGP laminated glass

Dupont. SGP is also called SentryGlas Plus, which is one kind of high-performance laminated material developed by Dupont, Kuarary acquired Dupont at the end of 2014.

SentryGlas Plus interlayer laminated glass also knows as SGP laminated glass. SentryGlas is used in facades where high strength is required. If the glass is broken, the laminate keeps its form. The Sentry Glass material is 100 times stiffer and 5 times tougher than traditional laminate.

SGP is an ionoplast interlayer which means it is not compatible with other interlayers, you cannot combine SGP with PVB/EVA based interlayers when manufacturing custom laminated glass.

The interlayer is 5 x stronger and up to 100 x stiffer than regular laminates such as PVB. This option provides the highest level of structural performance and edge stability for finished glass applications

Compared with PVB and SGP, EVA has better fluidity, lower melting temperature, and can be processed at temperatures up to 110 °C. SGP is called the ionic interlayer film (SentryGlas Plus), which is a high-performance interlayer developed by DuPont.

It is a clear, strong, and durable material that can withstand high impacts and extreme temperatures. The thickness of the SGP interlayer can vary, while the SGP interlayer from 0.76mm, 0.89mm, 1.52mm, 2.28mm, etc.

Laminated glass sound reduction occurs because of the interlayer that prevents noise from transmitting through the layers, offering peace and quiet where it’s needed. Laminated glass sound reduction is largely dependent on the thickness of the glass and inner layer.

Believe it or not, SGP laminated glass is the strongest option on the market – even stronger than cable or rod railing.
