Tempered glass is a kind of safety glass regularly used in applications in which standard glass could pose a potential danger. Tempered glass is four to five times stronger than standard glass and does not break into sharp shards when it fails. Tempered glass is manufactured through a process of extreme heating and rapid cooling, making it harder than normal glass.
The brittle nature of tempered glass causes it to shatter into small oval-shaped pebbles when broken. This eliminates the danger of sharp edges. Due to this property, along with its strength, tempered glass is often referred to as safety glass.
Toughened glass has two advantages over regular glass -- when it breaks, and when it doesn't. Because toughened glass is created with uneven heating that causes the cooling glass to form layers instead of a solid sheet, it is much more resistant to impact than "annealed" glass. It isn't indestructible, but when it does give way, this glass comes apart in a spray of cube-like pellets rather than jagged shards.
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 butyral (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.
1. Safety: 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.
2. Security: 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.
3. Sound Reduction: 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.
4. UV Control: 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.
5. 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.
6. 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.
7. Durability: Laminated glass is durable, it maintains its color and its strength for a very long time.
8. 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.
Insulating glass is a multi-glass combination consisting of two or more panes enclosing a hermetically-sealed air space. The most important function of insulation glass is to reduce thermal losses, which offers many advantages: lower energy consumption, perfect transparency by reducing the incidence of condensation on the warm air side and the possibility of using larger glazed areas without increasing energy consumption.
There are many benefits of utilizing insulated window and door products in your home. They not only lower one's energy costs, but also make homes cozier by improving comfort, decreasing condensation, as well as, diminish the effects of fading. Insulated units are also highly effective in reducing unwanted sound transmission.
In the summer, heat is transmitted through the glass and is absorbed by the walls, furniture, floors, etc. By using window and door products with a low solar heat gain coefficient, the solar radiation coming into one's home is decreased. This reduces the amount of heat entering the home, thereby improving one's homes' comfort level and lessening the amount of energy needed for cooling during warm weather months.
Moreover, during the cooler seasons, insulated products create warmer interior glass surfaces, reducing frost and condensation from forming.
Another benefit is that during daylight hours, sunlight is transmitted through the glass and is absorbed by the walls, furniture and flooring. Many materials, such as carpet, curtains, upholstery, artwork and wood may fade upon exposure to sunlight. Window glass selection influences the type and intensity of ultraviolet (UV) rays, which causes fading and degradation.
In these days of unprecedented crimes, understanding residential and commercial glass requirements along with aesthetics is the key. Glass in house windows should give you the ability to see more and shop fronts must bring maximum visual communication and daylight without compromising on safety.
With Security glass one does not need grills or shutters. The glass provides people with the ability to be safe without feeling caged in their own homes. It allows shop owners to advertise at night as the grill & shutters have now been replaced by Security glass.
Urban traffic sound is one of the main reasons of stress and fatigue. Ordinary glass is a good conductor of sound waves.
With most homes and offices coming up in high traffic zones there has been a pronounced shift in people looking for ways to reduce external sound inside.
There is an increasing demand for acoustic glass, particularly on busy and noisy streets and also in areas close to the airport. Acoustic glass is a laminated glass with 50-60% sound reduction. Thus less noise, less stress. Studies have shown that people are more productive, more creative and more comfortable, when unwanted noise is reduced . That means better value for residential consumers who want to enjoy home entertainment like the television, music, or maybe just some quiet time at home. It means more professionally designed theaters and entertainment venues. And improved privacy spaces, for home based businesses, medical clinics, counseling rooms and professional practices.

How does it work?
Noise levels are measured in decibels (dB).
A comfortable sound level is around 35dB in daytime and 30dB at night.
Acoustically insulating glass cuts out excess sound and the harmful effects of noise and is particularly effective in buildings near to high streets, urban traffic, motorways, train stations and airports.
The acoustic glass within a double-glazed unit comprises a special interlayer which acts as a dampening core to prevent sound frequencies from vibrating from one pane of glass to the other. This absorbs and weakens sound energy, helping to act as a barrier to noise.
This plastic interlayer also has the additional safety and security properties of laminated glass (see “safety and security glass” section).
Your home should be a place where you can shut out the world and escape the pressures of your working day. By fitting acoustic windows you can keep noise at bay and enjoy your surroundings in peace and quiet.
Acoustic glazing forms an effective barrier to external noise allowing you to sleep restfully in a tranquil environment.
You can enjoy your home at a sensible noise level so you can relax and unwind without additional stress.
Your family can study and concentrate without the distraction of excessive noise.
Reduce impact noise, particularly on conservatory roofs when it is raining.
Acoustic glass can be combined with many other products for multi-functional glazing, such as thermal insulation, solar control, low-maintenance and decorative glass.
