What is Laminated safety glass?
Laminated safety glass, also called sandwich glass and VSG glass, is a type of safety glass made by bonding two or more layers of glass together with an interlayer, usually PVB (polyvinyl butyral) or EVA (ethylene-vinyl acetate) or SGP (SentryGlas® Plus), under heat and pressure. Even if the glass breaks, the interlayer holds the fragments in place, significantly reducing the risk of injury and maintaining a barrier.
Laminated safety glass is widely used in applications where safety, sound insulation, and UV protection are important — such as building facades, skylights, glass railings, car windshields, and high-security areas.
Items for laminated safety glass
PVB laminated glass is a type of safety glass made by bonding two or more layers of glass with a layer of PVB (polyvinyl butyral) interlayer under heat and pressure. If the glass breaks, the fragments remain stuck to the PVB layer, reducing the risk of injury and keeping the glass intact.
- High Safety
In the event of breakage, the glass stays bonded to the interlayer, preventing shards from scattering — ideal for overhead and façade applications.
- Excellent Sound Insulation
The PVB interlayer helps dampen noise, making it suitable for homes, offices, and noise-sensitive environments.
- UV Protection
Blocks over 99% of harmful UV rays, protecting interiors from fading and sun damage.
SGP laminated glass is a type of high-performance safety glass made by bonding two or more layers of glass with SGP (SentryGlas® interlayer) under heat and pressure. Compared to traditional PVB, SGP offers significantly greater strength and stiffness. Even when the glass breaks, the interlayer remains intact and holds the structure firmly, making it ideal for demanding applications.
- High Strength and Rigidity
SGP is five times stronger and up to 100 times stiffer than PVB, allowing the glass to remain upright and structurally stable even after breakage.
- Superior Impact and Tear Resistance
Perfect for hurricane zones, high-rise buildings, bomb-resistant designs, and seismic areas.
- Long-Term Durability
SGP interlayers glass are more resistant to moisture and UV exposure, meaning they are less likely to discolor or delaminate over time — ideal for exterior glazing.
EVA laminated glass is made by bonding two or more layers of glass with EVA (ethylene-vinyl acetate) interlayers under vacuum and heat. EVA films offer excellent clarity, moisture resistance, and strong adhesion. They can also encapsulate decorative materials like fabrics, metal mesh, or printed films, making them ideal for interior design, partitions, skylights, and decorative glass applications.
- Versatile Decorative Options
EVA allows for lamination with fabrics, prints, wire mesh, and other decorative elements for creative and artistic glass designs.
- Strong Moisture and Weather Resistance
Compared to PVB, EVA performs better in humid or outdoor environments due to its lower sensitivity to moisture.
- Flexible Processing
EVA lamination does not require an autoclave, making it cost-effective and ideal for custom or small-batch production.
Bulletproof laminated glass is a high-security glass made by layering multiple sheets of glass and high-strength interlayers such as PVB, SGP, or polycarbonate (PC). This construction absorbs and disperses the energy of a bullet, preventing penetration while keeping the glass intact. It is widely used in banks, embassies, military facilities, prisons, and other high-security applications.
- Superior Ballistic Protection
Effectively resists gunfire and impact, providing reliable anti-penetration performance.
- Structural Integrity After Impact
Even when struck, the glass remains bonded to the interlayer, reducing shattering and minimizing injury risks.
- Customizable Protection Levels
Available in various configurations tailored to resist different types of ballistic threats, from handguns to rifles.
Annealed laminated glass is made by sandwiching a plastic interlayer between two sheets of regular (non-tempered) glass and then heating and pressing them together. If the glass breaks, the interlayer holds the fragments in place, helping prevent injuries and keeping the structure intact.

Switchable Glass, also known as PDLC Smart Laminated Safety Glass (Polymer Dispersed Liquid Crystal), is an intelligent glass product that changes its appearance from transparent to opaque when powered on or off. This is achieved by applying an electrical voltage to a special PDLC film laminated between glass layers, allowing for on-demand privacy and light control.
- How It Works?
Power ON: The liquid crystals align, allowing light to pass through – the glass becomes clear.
Power OFF: The crystals scatter light randomly – the glass turns frosted/opaque.
- Instant Privacy
Switches between transparent and opaque in milliseconds.
- Energy Efficient
Reduces need for blinds and helps control solar gain.
- Projection Surface
The opaque mode can be used as a rear projection screen.
