Tell us about your laminated glass requirements
Laminated Glass Manufacturer
Laminated glass consists of two or more glass layers bonded with a PVB or SGP interlayer, creating a safety glazing solution that holds together when shattered. It provides superior impact resistance, sound insulation, UV protection, and security — making it essential for curtain walls, overhead glazing, and safety-critical applications.

How We Test the Quality of Our Laminated Glass
Adhesion Test (Pummel)
Tests the bond strength between glass and interlayer — rated on a 0–10 scale per EN ISO 12543
Boil Test (2-hour)
Submerges laminated samples in boiling water to detect delamination, bubbles, or edge defects
Bake Test (High Temperature)
Exposes panels to 100°C+ for extended periods to verify interlayer stability under heat
Impact Test (Drop Ball)
Drops a steel ball from specified heights to confirm safety glazing performance under impact
UV Exposure Test
Simulates long-term sunlight exposure to verify interlayer does not yellow or degrade
Dimensional & Visual Inspection
Checks thickness, size tolerance, edge quality, interlayer alignment, and optical clarity

What Is Laminated Glass?
Laminated glass is a type of safety glass made by bonding two or more layers of glass together with an interlayer — typically polyvinyl butyral (PVB) or SentryGlas® Plus (SGP). The assembly is heated and pressed in an autoclave, creating a permanent bond.
When broken, the glass fragments remain adhered to the interlayer instead of falling out, preventing injury and maintaining a barrier. This makes laminated glass the mandatory choice for overhead glazing, balustrades, floor glass, and any application where post-breakage performance is critical.
Benefits of Laminated Glass
Enhanced Safety
Glass stays bonded to interlayer when broken — no falling shards
Sound Insulation
PVB interlayer dampens noise by up to 35-40 dB (acoustic PVB available)
UV Protection
Blocks up to 99% of harmful UV radiation, protecting interiors from fading
Weather Resistance
Withstands hurricanes, cyclones, and severe weather — hurricane-rated options available
Security & Anti-Theft
Multi-layer lamination resists forced entry, bullet impacts, and blast pressure
Design Versatility
Colored PVB, printed interlayers, frosted, and decorative options for creative facades
Energy Efficiency
Combined with Low-E coating to reduce solar heat gain and lower HVAC costs
Durability
Long lifespan with minimal maintenance — interlayer does not degrade under normal conditions
Laminated Glass vs. Tempered Glass
| Property | Laminated Glass | Tempered Glass |
|---|---|---|
| Construction | Two+ glass layers bonded with PVB/SGP interlayer | Single glass panel heat-treated |
| Break Behavior | Cracks but stays in frame — held by interlayer | Shatters into small granules, falls out |
| Safety | Post-breakage barrier remains intact | Safe fragments but no residual barrier |
| Strength | Moderate (depends on layers) | 4-5x stronger than annealed glass |
| Sound Insulation | Excellent — interlayer dampens noise 35-40 dB | Same as equivalent annealed glass |
| UV Protection | Blocks up to 99% UV radiation | No UV protection without coating |
| Applications | Overhead, balustrades, floor glass, hurricane zones | Doors, facades, showers, railings |
| Cost | Higher (multi-layer + autoclave process) | Moderate (single panel processing) |
FAQs About Laminated Glass
Is laminated glass stronger than tempered glass?
Laminated glass is not necessarily stronger in terms of bending strength — tempered glass is 4-5x stronger than annealed. However, laminated glass offers superior post-breakage performance: when broken, it stays in the frame held by the interlayer, maintaining a barrier. For maximum strength and safety, use tempered laminated glass which combines both benefits.
Can laminated glass block noise?
Yes. The PVB or SGP interlayer in laminated glass acts as a sound dampener, reducing noise transmission by 35-40 dB depending on thickness and interlayer type. Acoustic PVB (such as Saflex QS) provides even higher sound reduction, making laminated glass the preferred choice for buildings in noisy urban environments.
Does laminated glass protect against UV rays?
Yes. Standard PVB interlayer blocks up to 99% of harmful UV radiation. This protects interior furnishings, flooring, and artwork from fading. It also reduces solar heat gain when combined with Low-E coated glass, contributing to energy efficiency.
Can laminated glass be customized?
Absolutely. We offer full customization including custom sizes up to 18m × 3.3m, various interlayer types (PVB, SGP, colored PVB, acoustic PVB), different glass combinations (tempered + laminated, Low-E + laminated), custom shapes, edge treatments, and surface finishes.
Where is laminated glass most commonly used?
Laminated glass is required by building codes for overhead glazing (skylights, canopies), glass balustrades, floor glass, and hurricane/cyclone zones. It is also widely used in curtain walls, shopfronts, acoustic partitions, bulletproof applications, and automotive windshields.
