When it comes to combining transparency, safety, and performance in architecture and construction, laminated glass has no equal.
When it comes to combining transparency, safety, and performance in architecture and construction, laminated glass has no equal. But did you know there are different types of laminated glass depending on the interlayer used? Each type offers unique characteristics suited for specific environments and project needs.
In this article, we explore how many types of laminated glass exist, what makes them different, and how you can choose the right type for your project, whether it’s a facade, balcony, or an outdoor application.
What Is Laminated Glass?
Laminated glass is a type of safety glass consisting of two or more layers of glass bonded together with an interlayer material. This interlayer holds the glass sheets together even when shattered, preventing the dangerous scattering of sharp shards.
Glass laminated structures not only offer safety but also provide enhanced sound insulation, UV protection, and even energy efficiency. Different types of laminated glass are defined primarily by the type of interlayer used—each bringing specific strengths to the table.

Types of Laminated Glass Based on Interlayer
Understanding the types of laminated glass starts with understanding the interlayer materials: PVB, EVA, and SGP.
PVB Laminated Glass
What is PVB?
Polyvinyl Butyral (PVB) is the most commonly used interlayer in laminated glass. Known for its flexibility and adhesion properties, PVB delivers excellent optical clarity and impact resistance.
Key Features:
- Superior clarity and light transmission
- Effective sound insulation
- Blocks up to 99% of UV radiation
- Standard choice for automotive windshields and architectural glazing
- Provides good post-breakage behavior by holding fragments together
Applications:
- Residential and commercial windows
- Skylights and overhead glazing
- Interior glass partitions
- Automotive glazing
PVB laminated glass is often considered the default standard due to its balance between safety, aesthetics, and affordability.
EVA Laminated Glass
What is EVA?
Ethylene Vinyl Acetate (EVA) is another popular interlayer material, particularly appreciated for its excellent adhesion to various materials, including glass, plastic, and metals. EVA laminated glass offers improved durability in environments where moisture and heat are concerns.
Key Features:
- Excellent moisture resistance
- High adhesion strength
- Better performance in extreme weather conditions
- Longer durability compared to standard PVB
- Good sound and thermal insulation
Applications:
- Outdoor balconies and railings
- Canopies and skylights
- Decorative glass panels with embedded materials
- Glass floors and stairs
When working in humid, tropical, or outdoor environments, EVA laminated glass can be a superior choice. Learn more about exterior applications here:

SGP Laminated Glass
What is SGP?
SentryGlas® Plus (SGP) is an advanced interlayer developed for high-performance laminated glass. It offers five times the tear strength and up to 100 times the rigidity of standard PVB interlayers.
Key Features:
- Exceptional strength and stiffness
- Maintains structural integrity after breakage
- Greater resistance to moisture and UV exposure
- Thinner glass can be used without sacrificing strength
- Minimal creep under long-term load and high temperatures
Applications:
- High-rise building facades
- Hurricane-resistant glazing systems
- Structural glass walls
- Security and blast-resistant glazing
For projects where extreme performance is needed, SGP laminated glass is the clear choice, even in the most challenging climates and structural designs.
How to Choose the Right Laminated Glass
When selecting laminated glass types for a project, you should consider:
- Location and exposure: Outdoor vs. indoor
- Weather conditions: High humidity, extreme heat, hurricane zones
- Desired performance: Acoustic insulation, security, strength, UV protection
- Design preferences: Clear, colored, patterned, or embedded decorative elements
- Building codes: Specific regulations for safety and structural requirements
By understanding these factors and choosing the appropriate interlayer material, you ensure optimal performance and longevity.
Laminated Glass Price and Cost Factors
The laminated glass price varies depending on:
- Glass thickness (standard options include 6.38mm, 8.76mm, 10.76mm, 13.52mm)
- Type of interlayer (PVB, EVA, SGP)
- Size and complexity of the panels
- Additional treatments like tinting, low-E coating, or digital printing
General Price Estimates:
| Type of Laminated Glass | Price Range per m² |
|---|---|
| PVB Laminated Glass | $30–$50 |
| EVA Laminated Glass | $50–$70 |
| SGP Laminated Glass | $80–$150 |
Custom designs or high-spec performance panels, such as SGP laminated glass for hurricane resistance, tend to sit at the higher end of the pricing scale.
For precise costs, always contact trusted laminated glass manufacturers.
Advantages of Laminated Glass Across All Types
Regardless of the interlayer, all laminated glass types offer:
- High safety performance to prevent injury
- Enhanced acoustic insulation for quieter interiors
- UV protection to protect furnishings and people
- Energy savings through solar and thermal control
- Long-term durability against weather and wear
- Design versatility with various aesthetic options
These advantages make glass laminated systems indispensable for both residential and commercial projects.
