In double glazing glass window, the glass is known as Low – Emissivity and Low E and it is used for thermal insulation. The glass is coated with a transparent metallic coating and this coating works in two different ways to cut down heating energy. The double performance of this coating stops the heat from getting inside the room, but, allows the light from the sun. Thermal insulation should be used on face 3 or 2 of DG units.
Currently, the energy cost is rising high and also the building regulations made by the Government are also causing the rise in energy cost. That is why it is even more necessary to find the best and most cost-efficient thermal insulation glass. The BRRC (British Fenestration Ratings Council) has commenced an official WER (Window Energy Ratings) table starting from A to G. The ‘A’ in the list means most energy-efficient product. However, the government certified the window with ‘C’ rating or higher so people can use these products for energy-saving and it is supported by EST (Energy Saving Trust).
Types of Low-E Solutions:
The efficient double glazing and thermal insulation glass contain layers of metallic coating that is manufactured using a technology called as falter, below void conditions. This superior process builds up an extremely resistant; however, to get a clear appearance, you should get the thin coating glass. This thin coating glass allows maximum heat and sunlight into the room for better energy gain. Some of this thermal insulation glass controls the heat by 24 percent more than the normal coated thermal insulation glass and compared to standard double glazing window it controls the heat by 40 percent. You can also save energy by using warm-edge spacer bars called “Thermal Break,” it can reduce the heat around window edges by up to sixty-five percent.
Integrating thermal insulation glass with other kinds of glasses can also be produced by laminated and toughened double glazing window glass. You can also use several other combinations with self-cleaning, solar control, acoustic, and decorative glass.
Noise pollution is also one of the major problems today, especially in crowded areas like busy roads, air-traffic, etc. But, now you can protect your home from noise pollution with acoustic glass as it reduces the noise or sound to enter the home through the windows.
A Sound is also a form of energy that is occurred by molecules vibrating in liquid, gas, or solid, and these vibrations are called as sound waves. The pitch or frequency of a noise is measured in hertz, which measures the number of sound waves produced per second. High-frequency sound waves are transferred by short sound waves and low-frequency noises are carried by longer waves. The definite intensity or level of noise/sound is measured in DB (Decibels).
Improving acoustic insulation: The acoustic insulation can reduce the sound energy waves with the acoustic glass. The AI (Acoustic Insulation) properties of a double glazing glass window are measured with the ‘R’ sound RI (Reduction Index). For instance, if you have a window with an R-reduction-index of twenty decibels must reduce sixty decibels outside traffic sound level to forty decibels inside the room.
