Laminated Safety Glass
Laminated Safety Glass is combining two or multi glass panels with interlayer under high temperature and pressure. The interlayer can be EVA, PVB, SGP or more to bond glass permanently. The biggest advantage of Laminated Glass is its safety, once any glass beakage, the interlayer will keep glass integrity and prevent injury. Laminated Safety Glass is widely used in glass balsutrade, balcony, glass skylight, poolfence, glass facade.
LETEL® Glass Offers Architectural Laminated Glass.
PVB Liminated Glass
PVB (Polyvinyl Butyral) Laminated glass is most widely used interlayer. According to the interlayer types and function, LETEL offers various PVB options for customers:
- Clear PVB interlayer
- Extra Clear PVB interlayer
- Colorful PVB interlayer
- Soundproof PVB interlayer
- Stiff PVB interlayer-DG41, Trosifol Extra Stiff
- UV selec PVB interlayer
EVA Liminated Glass
EVA has a good fluidity under high temperature, thus additional functional layers such as organic, PDLC layer can work with EVA interlayer to make beautiful decorative glass or functional glass. EVA has good water resistance, but its UV resistance is weak. It is easy to yellow and black in long-term sun exposure, so it is mainly used for indoor partitions.
With less glass haze and more light transmission than Sentryglas, EVA is a comparable choice in most applications. A revolutionary thermoplastic copolymer resin that is both non-sticky and inert to water moisture it offers edge stability and the most design opportunities.
(EVA /PVB /SGP)sandwiched by the glass sheets. In case of breakage the interlayer will hold the glass fragments together. It is manufactured through a process of heat and vacuuming.
Interlayer Film : SGP / PVB / EVA
Cost: SGP > PVB > EVA
Safety: SGP > PVB > SGP
Color: EVA > PVB > SGP
(also EVA does well connected with many different materials,so it’s a very nice interlayer for decoration glass)
Bulletproof glass is als laminated glass, it is several film and glass laminated.
Normally,it comes with PVB,dear client,if you have enough budget,then think about SGP
SGP Liminated Glass
SGP is short for SentryGlas Plus,it’s proved the most stiff and most safe interlayer used in architectural glass.Compared with PVB interlayer,SGP has many advantages:
- High Strength:Under same thickness and combination,the SGP lami bearing capability is two times that of PVB lami,and bending deflection is ust 1/4 of PVB lami.
- High shearing modulus:if any breakage,the SGP can stick the glass and form a temporary structure while keeping small bending deformation,it can withstand a certain amount of load and whole piece laminated glass won’t fall or deform.
- Extra Clear Color and super weathering resisitance.SGP yellowing coefficient is less than 1.5,usually been made into low iron SGP laminated glass to get best glass appearance.

Laminated Safety Glass is composed of at least two panes held together by a polyvinyl butyral (PVB) film.
Such glass is often used in architecture , for overhead glass or other glass that prevents people from falling, and in the automotive industry. One essential reason for its use in such applications is that Laminated Safety Glass holds splinters together. When the pane breaks, the splinters of glass generally remain stuck to the transparent PVB film. It is difficult to pierce the film, which considerably reduces the risk of injury.
