What is laminated glass?
Laminated glass is a type of insulated glazing unit composed of two or more sheets of glass with a clear plastic layer, also known as “the interlayer”. It is often used in buildings to create extra strength in the windows and to prevent shattered pieces from injuring people near the building.
Laminated glass generally provides better insulation and sound reduction than single-glazed windows since there is an air gap between the sheets. However, it can be more expensive than single-glazed windows.
Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyric (PVB), between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the glass.
Available in different sizes
Benefits: safety, security, sound control, and ultraviolet screening.

What is laminated glass used for?
In buildings, laminated glass is used in the external walls, as well as windows. In automobiles, laminated glass is used inside and rear windows and windshields.
Although they are sometimes referred to as “safety glass” or “tempered glass”, laminated glasses are not made of those materials and do not meet the definition of safety or tempered glass set by national standards, such as ANSI Z97.
Is laminated glass expensive?
Laminated glass can be more expensive than single-glazed windows, but the added safety and energy efficiency it provides can offset this somewhat.
How is laminated glass made?
Laminated glass is made by bonding two or three pieces of annealed glass together under heat and pressure in a laminating line.
Laminated glass invented what year?
The basic design for laminated glass was patented in the United States in 1899 by Rudolph H. Schage, an American glass engineer and fabricator.
Does laminated glass satisfy ANSI Z97?
No. Laminated glasses are not accorded the status of safety or tempered glasses under national standards such as ANSI Z97, which only covers tempered and safety equipment.
Laminated glass how much noise reduction it makes?
The laminated glass in a window or door creates a transparent, air-filled space that allows sound waves to travel freely through it. This makes the glass an economical choice for noise reduction, although increased sound vibration dampening can always be applied to increase the noise reduction.
What are the differences between SGP laminated glass and PVB laminated glass?
SGP = Spherical Glass Particle (or Silica Particle) Laminated Glass (or Safety Glass) is a type of laminated glass that uses silica glass as the interlayer between two or more sheets of normal glass. It is most commonly used in high-security buildings and windows with a fire-resistance rating.
Does the laminated glass have a life span?
Laminated glass, which is generally intended to be used for buildings, has no specified life span. However, laminated glass is usually made to remain functional with little or no maintenance for at least 50 years.
Is laminated glass harmful to the environment?
Some types of laminated glasses are harmful to the environment and should not be broken during their lifetime.
