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 provides significant sound control characteristics, effectively blocking out entry, while screening out the sun’s harmful ultraviolet rays.
When laminated glass is broken, the glass particles adhere to the vinyl interlayer, reducing the risk of shattering glass. Laminated glass tends to stay in the opening, securing it.
Bear Glass offers Custom laminated glass which is constructed by bonding a polyvinyl butyral (PVB) plastic interlayer between two pieces of glass under heat and pressure to form a single piece of glass. Custom Laminated glass can be made using many combinations of clear, tinted, translucent, or reflective glass. Various colors and types of inter-layers may be used as well.
Benefits of Laminated Glass
Ordinary window glass is brittle, breaking into long sharp pieces which can cause serious injuries. The principal feature of Laminated safety glass is that the interlayer absorbs the energy impact and hence resists penetration. Although the glass may break, the glass fragments remain firmly bonded to the interlayer, minimizing the risk of injuries.
Burglars often try to break windows to get inside the house or a building and here the laminated glass plays an important role in resisting their intrusion. Even if the glass breaks the interlayer continues to safeguard the building until the glass is replaced.
Noise gains easiest entry to homes and buildings through windows and doors. Laminated glass proves an excellent barrier to noise, it has better Sound Transmission Loss as compared to glass of similar thickness in the frequency of 125 Hz to 4000 Hz. Also it eliminates the coincidence dip that is associated with the monolithic glass because of the viscoelastic property of the interlayer material.
Solar Energy Control
While natural light is important for us too much sunlight can also mean too much heat gain inside the building. Laminated glass when used in combination with reflective glass, tinted glass or low e glass provides excellent reduction in the Solar Gains as well as reduction of sound transmission through the window.
The major cause of deterioration and fading of furnishings and pictures is the chemical reaction caused by short-wavelength UV radiation. UV absorbing additives in the interlayer in laminated glass can screen out almost all these damaging rays.
Protection from weather and natural disasters
If broken, laminated glass remains in its frame, preventing interior damage while reducing flying glass protects people both indoors and outdoors. Areas subjected to heavy winds and rain such as hurricanes or cyclones, buildings often need extra protection. Flying debris carried by these winds can shatter the glass and injure people. Laminated glass can be designed to remain intact and in its frame. Buildings that are situated in areas subjected to heavy winds and rains such as hurrican and cyclones, often need extra protection.
Laminated glass is durable, it maintains its color and its strength for a very long time.
Low visual distortion
Laminated Glass is usually glazed in an annealed form, avoiding the distortion caused by roller waves in the tempered and heat strengthened glass. So the facades having laminated glass have sharp reflected images and fewer distortion.
