What is Laminated Glass?

Laminated Glass is a multifunctional glazing material that can be used in a variety of applications. It is manufactured by permanently bonding two or more lites of glass with layers of polyvinyl butyral (PVB) interlayer, under heat and pressure, to create a single construction. Laminated glass products are ideal for Sloped/Overhead Glazing; Museums, Prisons, Government Buildings; Jewelry Stores, Banks, Airports; Schools, Hospitals, Hotels; Interior Partitions, Office Buildings and Safety Glazing Applications.

Bullet Resistant, ArmorResist®

Laminated glass can be designed to resist attacks by a wide range of weapons. There are many standards and test methods available. Almost all of these have two main requirements: (1) the glazing must resist penetration by a specified bullet and (2); the spall or flying shards of glass leaving the rear face, as a result of the impact, must be limited. Bullet-resistant laminated glass can typically meet both of these requirements. It is important to note that some ArmorResist® glazing materials are not classified as forced-entry resistant.

Forced Entry, ArmorProtect®

ArmorProtect® is used where glazing is required to resist penetration for some considerable time, typically measured in minutes rather than seconds. These types of attacks are usually planned, sustained attacks executed by more than one intruder having experience of security glazing and using more than one type of weapon. Oldcastle BuildingEnvelope™ offers three types of protection: ArmorProtect®, ArmorProtect® Plus and ArmorProtect® Max

Light & Solar Control

Laminated architectural glass may be designed to reduce solar energy transmittance, control glare and screen out ultraviolet (UV) radiation. Transmitted solar energy is reduced by the use of tinted or coated glass, colored interlayers, or combinations of each that absorb part of the solar radiation in the ultraviolet, visible and near-infrared ranges. The absorbed energy is converted to heat, and a large portion is dissipated to the exterior

Overhead Glazing

Glass which slopes more than 15° from the vertical is considered sloped glazing by the major model building codes. Laminated glass is the preferred product for sloped and overhead glazing, because the glass is retained in the opening, even when broken, reducing the possibility of injury from falling glass. Costly and unsightly screens are therefore not required. Laminated products are widely used in malls and in atriums in hotels and offices.

Sound Control Glass

Shielding a building's environment from increasing noise levels, especially near airports and busy highways, is a critical factor in the specification of glazing materials for both new and renovated structures. Laminated glass is a proven, effective solution for acoustical protection.
