PVB laminated glass is valued for its visual clarity and durability and for its ability to meet rigorous global safety, performance, sustainability standards.
PVB laminated glass is not only valued for its visual clarity and durability but also for its ability to meet rigorous global safety, performance, and sustainability standards. In industries where both aesthetics and protection matter—from high-rise architecture to automotive manufacturing—PVB laminated glass is relied upon to deliver certified quality under diverse conditions. This article explores the most important certifications, testing requirements, and industry standards that PVB laminated glass must meet, highlighting why it remains the preferred laminated glass type in modern design and construction.
What Is PVB Laminated Glass and Why Certification Matters
PVB laminated glass is composed of two or more layers of glass bonded together with a polyvinyl butyral (PVB) interlayer under heat and pressure. The interlayer ensures that even if the glass is broken, it holds together, significantly improving safety. Beyond its structural integrity, PVB laminated glass also offers acoustic insulation, UV protection, and design flexibility.
In today’s competitive construction and manufacturing environments, compliance with international standards is not optional—it’s essential. Certified PVB laminated glass guarantees performance in impact resistance, fire safety, acoustic control, thermal insulation, and light transmission. This is critical for regulatory approval, liability reduction, and customer trust across sectors.

Global Certifications and Testing Standards for PVB Laminated Glass
Several globally recognized standards organizations test and certify PVB laminated glass for its intended applications. These include ANSI, ASTM, EN, ISO, and others.
ANSI Z97.1 (USA)
This American standard specifies the safety performance of architectural safety glazing materials. PVB laminated glass must pass impact resistance tests simulating human collision or accidental impact to meet ANSI certification. It’s commonly required in schools, commercial buildings, and residential applications.
ASTM C1172 (USA)
This is the primary ASTM standard that covers laminated architectural flat glass. It defines requirements for construction, testing, and performance of laminated glass using PVB or other interlayers. ASTM C1172 certification is essential for building code compliance in the United States.
EN 14449 (Europe)
The European norm EN 14449 governs laminated glass and laminated safety glass. It requires PVB laminated glass to be tested for mechanical strength, resistance to environmental influences (such as moisture and temperature), and overall performance in structural applications. This certification is essential for CE marking in Europe.
BS EN 12600
This European standard tests the pendulum impact resistance of laminated safety glass and classifies it into categories such as Class 1(B)1, 2(B)2, and 3(B)3 based on impact energy levels. High-performance PVB laminated glass often qualifies for Class 1(B)1, indicating high resistance.
ISO 12543
An international standard series that sets out detailed specifications for laminated glass, including weathering performance, adhesion, and long-term durability. ISO-certified PVB laminated glass ensures global consistency in quality.
AS/NZS 2208 (Australia & New Zealand)
Specifies safety glazing materials for buildings and is required for PVB laminated glass to be legally used in architectural projects in Australia and New Zealand. It includes impact, fragmentation, and aging tests.
GB 15763.3 (China)
The Chinese national standard outlines laminated glass requirements for buildings. Similar to EN 14449, this standard ensures compliance with structural and safety needs in local projects using laminated glass.
Fire Resistance Standards
Although standard PVB laminated glass is not classified as fire-resistant glass, there are laminated configurations designed to meet fire-rating certifications such as:
- EN 13501-2 (Fire classification of construction products)
- UL 10C (Fire Tests of Door Assemblies)
- BS 476 Part 22
Fire-rated laminated glass often uses intumescent interlayers combined with PVB to maintain safety and transparency while slowing the spread of fire.
Acoustic Certification and Performance Testing
Because PVB laminated glass significantly reduces sound transmission, it is often tested and certified to acoustic standards such as:
- ISO 140-3: Laboratory measurement of airborne sound insulation
- EN ISO 10140-2: Measurement of sound insulation performance in building elements
Acoustic PVB interlayers are specifically engineered to increase sound attenuation in office buildings, schools, and hospitality applications.

Impact Resistance and Safety Glass Ratings
PVB laminated glass must pass various impact resistance standards depending on the region and application. These include:
- Category II or I impact rating per ANSI Z97.1 (for storefronts, balustrades, etc.)
- Hurricane impact testing (e.g., ASTM E1886/E1996) for coastal installations
- Security glazing tests (e.g., EN 356 or UL 972) for burglary- and bomb-resistant glass
Some projects require laminated glass to resist forced entry or blast impacts. In these cases, multiple PVB interlayers may be used in combination with thicker glass panels.
Sustainability and Environmental Certifications
Modern buildings often aim for environmental certification, and materials like PVB laminated glass play a role. Many manufacturers offer glass certified to contribute to:
- LEED (Leadership in Energy and Environmental Design) points
- BREEAM (Building Research Establishment Environmental Assessment Method)
- Environmental Product Declarations (EPDs)
- HPDs (Health Product Declarations)
Additionally, some PVB interlayers are available with recycled content, further supporting green building goals.
Certifications for PVB Laminated Glass Manufacturers
In addition to product certifications, reputable PVB laminated glass manufacturers themselves must meet quality assurance and production standards such as:
- ISO 9001 (Quality Management Systems)
- ISO 14001 (Environmental Management Systems)
- CE Marking (Europe)
- IGCC/IGMA Certification (for insulated glass units in the US and Canada)
When sourcing laminated glass, verifying the manufacturer’s certifications ensures consistent quality, durability, and performance in demanding conditions.
PVB Laminated Glass Installation and Maintenance Compliance
Certified PVB laminated glass should also be installed according to recommended practices outlined in manufacturer documentation and industry guidelines such as:
- GANA (Glass Association of North America) Laminated Glazing Reference Manual
- FGIA (Fenestration and Glazing Industry Alliance) guidelines for curtain wall and window system integration
Improper PVB laminated glass installation can lead to moisture intrusion, edge delamination, and reduced performance. Additionally, PVB laminated glass care and maintenance should align with guidelines that preserve the glass and interlayer integrity without voiding warranty coverage.
