LAMINATED GLASS

Laminated glass is a multi-layered safety glass produced by bonding two or more glass sheets under heat and pressure with special interlayer materials such as PVB (Polyvinyl Butyral) or Ionoplast (Sentry Glas). The interlayer can be transparent or opaque, and is available in both colored and colorless options.

In the event of breakage, the glass fragments adhere to the interlayer, preventing them from scattering. This significantly reduces the risk of injury. Due to this feature, laminated glass is classified as a safety glass in accordance with the EN 14449 standard.

In addition, laminated glass offers high impact resistance as defined by EN 12600, helping to prevent unauthorized passage. It also meets EN 356 requirements for resistance to forced entry, making it a reliable choice for applications such as shopfront glazing, sloped facades, and the inner panes of overhead or insulating glass units.

Thanks to its low UV transmittance, laminated glass helps preserve the original colors of interior furnishings by protecting them from sun damage. For projects requiring specific levels of UV transmission, interlayers with customized UV performance—such as PVB or Ionoplast (Sentry Glas)—are available.

LAMINATED GLASS SPECIFICATIONS

Safety and Durability

Upon breakage, glass fragments adhere to the interlayer, preventing dispersion and significantly reducing the risk of injury.
Interlayer thicknesses are available in standard options of 0.38 mm, 0.76 mm, 1.14 mm, 1.52 mm, 1.9 mm and 2 mm (for customized interlayer configurations tailored to your project, please contact us).
Impact resistance is generally classified as class 1B1 according to the EN 12600 standard.
Resistance to burglary and external impacts is ensured according to EN 356; laminated glass structures can consist of 3 to 7 layers.

UV Protection

Laminated glass blocks 96% to 99% of ultraviolet (UV) radiation, minimizing color fading of interior furnishings.

Acoustic Performance

Special acoustic PVB interlayers provide sound insulation levels up to 32-38 dB, effectively reducing external noise.

Thermal Insulation and Energy Efficiency

Low-E coated laminated glass can achieve thermal transmittance (Ug) values of 1.0 W/m²K or lower, contributing to improved energy efficiency.

Optical Properties

Ultra Clear Laminated Glass offers light transmittance exceeding 91%.
Standard laminated glass generally provides light transmittance between 85% and 90%.

Application Areas

Display windows, roof and ceiling glazing, balustrades, interior partitions, museum showcases
Bank branches, hospitals, schools, police stations
Sports complexes and high-traffic public areas

TYPES OF LAMINATED GLASS

By Glass Type:
• Float Laminated Glass: Produced by laminating standard float glass; suitable for general applications.
• Tempered Laminated Glass: Manufactured by laminating heat-treated tempered glass; ideal for areas requiring high impact resistance.
• Heat Strengthened Laminated Glass: Offers higher strength than float glass, but less than tempered glass.
• Tinted or Colored Laminated Glass: Made using colored glass sheets or colored PVB interlayers; preferred for architectural and decorative purposes.
• Curved (Bent) Laminated Glass: Produced by laminating thermally bent glass; commonly used in modern architecture and façade applications.

Acoustic Laminated Glass:
Developed using specially formulated acoustic PVB interlayers for areas requiring sound insulation. Delivers higher sound attenuation compared to standard laminated glass.

By Lamination Structure:
• Double Laminated Glass: Consists of two glass layers bonded by a single interlayer.
• Multi-Layer Laminated Glass: Comprises three or more glass and interlayer components; typically used for bullet-resistant or high-security glazing.

By Application Purpose:
• Safety Glass: Prevents injury upon breakage by holding glass fragments in place.
• Bullet-Resistant Glass: Multi-layered and reinforced with thick interlayers; used in military and high-security facilities.
• Blast-Resistant Glass: Designed for areas with explosion risk in industrial or public settings.
• Fire-Resistant Laminated Glass: Uses special interlayers to delay the passage of smoke and heat during fire exposure.

CLEAR GLASS

"Clear and neutral from all angles"

Clear laminated glass consists of two or more sheets of ExtraClear glass bonded together with transparent PVB interlayers. Thanks to its low iron oxide content, it offers exceptional clarity and a color-neutral appearance. By varying the type of glass and the number of interlayers used, it can deliver a range of performance benefits including enhanced aesthetics, safety, sound insulation, and UV protection.

UV PROTECTION FEATURE

Laminated glass, thanks to the PVB or EVA interlayer used in its structure, can block up to 99% of ultraviolet (UV) rays. This feature helps prevent the fading of furniture, fabrics, and artworks in interior spaces due to sunlight, while also providing protection for human health.

COLOR OPTIONS

Common Colors of Laminated Glass :

Color	Description
Clear (Float)	Colorless glass with maximum light transmission; uses a clear interlayer.
Bronze	Light brown tone; provides solar control and privacy.
Grey (Smoke)	Reduces sunlight; offers a darker, aesthetically pleasing appearance.
Green	Greenish tone preferred in environmentally focused projects.
Blue	Blue tone used in modern façade designs; offers lower light transmission.
Reflective	Reflective coating on the surface creates a mirror effect; provides solar and thermal control.
Opaque / Satin / Frosted	Etched, sandblasted, or frosted surface treatments; ideal for interior privacy applications.
