Low E Glass from Express Toughening can help your home or business to cut energy costs and provide a more comfortable environment for your family, staff or customers. Conserving heat without inhibiting light, low E glass provides an excellent alternative to float glass, equipping your premises with a thermally insulating glass which reduces your heating bill, shrinks your carbon footprint and makes your insulation work for you!
What is Low E Glass?
Low E Glass, also known professionally as low emissivity glass, is a specially-made glass type designed to cut down on the naturally high thermal emissivity of window glass, therefore boosting the energy efficiency of a building by conserving heat. While window glass conventionally absorbs heat easily, aiding to an extent in the heating of a building in which it is installed, it also emits heat with the same ease, ultimately costing the energy efficiency of the building by releasing heat from the warmer interior of the building into the colder outside atmosphere.
When the building is warmer than the exterior, this action will transfer heat out of the building, and when it is cooler, the windows will work to transfer heat – in either case, this is likely to be an unwelcome mechanic, which would be better controlled by the application of low e glass or other insulative methods.
Low E Glass is different from other window glass thanks to an extremely thin film coating that is added to the glass, specially formulated to allow visible light to pass which tending to keep heat energy on the side of the glass where it originated.
This results in considerably improved control over the movement of energy, with thermal energy effectively reflected back to its source and light passing harmlessly through. With this feature active, a building is considerably more thermally independent of its surroundings, remaining at a more even temperature and conserving energy that would otherwise be vented uselessly into the atmosphere or expended in cooling the building on a hot day.
What Does Low Emissivity Mean?
“Low emissivity” means that the material in question will not absorb or emit energy as readily as the equivalent untreated material. Ordinary window glass is quite highly thermally emissive, with the ability to easily absorb heat and emit it. Usually, this is energetically costly for the building in which the window glass is installed, but with Low E Glass, the thermally reflective layer on the glass allows visible light to pass through, while reflecting the majority of infrared radiation (heat) back the way it came.
Since the glass doesn’t absorb this energy, it cannot emit it, and its emissions are therefore much lower – hence, “low emissivity glass”.
How Is Low Emissivity Glass Made?
Low emissivity glass is almost always made via one of two specialist industrial methods: pyrolytic chemical vapor deposition or magnetron sputtering. While these production and manufacturing methods require specialist equipment and expertise, Express Toughening has more than enough experience in leading the specialist glazing industry to provide Low E Glass to you whenever you need it, regardless of the difficulty. Get in touch with us today on 020 8500 1188 or visit our website to talk to our experts about how Low E Glass can help you – we can provide any information you may need and answer any questions you might have about Low Emissivity Glass. In any case, Low E Glass is made by the following processes:
Pyrolytic Chemical Vapor Deposition
In pyrolytic chemical vapor deposition, a vacuum is used to deposit extremely thin layers of specialist materials to a prepared surface, in ways that traditional layering methods simply cannot. In the case of Low Emissivity Glass, the crucial layer responsible for the reflection of thermal energy back into the room is deposited this way. Only a few molecules thick, and much, much thinner than a hair, the reflective layer is evenly and smoothly distributed thanks to the chemical vapor deposition method, making sure that the Low E Glass performs to an even standard across its entire surface and guaranteeing high standards for our clients.
Magnetron sputtering achieves the same result in a different way, by beginning with separate components: the glass and the material to be deposited. The material to be deposited is bombarded with energy, and begins to “sputter” particles onto the surface of the glass. This process results in an even coating of particles onto the glass, providing the extremely fine, extremely even coating required for low emissivity glass.
How Can Low E Glass Help Me?
Low emissivity glass is defined by its ability to reflect thermal energy away instead of absorbing and emitting it, which makes it a more capable insulator than normal window glass, which has a comparatively high ability to absorb and emit thermal energy. With Low Emissivity Glass, your heating system will work less hard to keep the building warm, and your cooling system will have an easier time cooling it down – both of which translate to energy savings. Keep your energy bills as low as possible, reduce your carbon footprint and help to make your home or business as cost-effective as possible with low E glass from Express Toughening.
