Pros and Cons of Low E Glass
The first of the great benefits of low-emissivity glass is the superior insulating power it adds to your windows. Low E glass has better insulating properties thanks to its low emissivity film, which makes the harsh winters a lot warmer for residents. But it is not limited only by the insulating capacity. During the hot summer months, Low E Glass greatly helps to maintain a comfortable indoor temperature. Potentially suitable for hot summer indoor conditions. Low E Glass prevents nearly 100% of UV radiation from entering your home. This not only protects your family, but your furniture as well, as UV light has a particularly nasty habit of having a kind of whitening effect on your carpets and furniture, causing them to lose their color. As mentioned, soft coated low E glass contains a low emissivity coating on the surface sealed inside the device, which means the coating is less likely to be damaged or scratched and is likely to retain much of its thermal insulation to protect it from the sun. Low E glass makes your home more energy efficient, potentially saving you money on heating bills. This reduction in your heating bills goes alongside a reduction in your overall energy consumption.
One of the disadvantages of Low E Glass can be the loss of natural light transmission. However, depending on how you look at it, this could be an advantage or a disadvantage. Low E glass can also be easily combined with other useful features such as increased safety, noise insulation or easy cleaning technology.

LoE Performance OR How LoE Works?
Important
When replacing the glass in your windows and doors, we will make sure to match the existing windows in the house. Our specialist will always offer the best Low-e options for a higher UV protection and energy efficiency
Loss of energy in a home through windows and doors is common, but most of the energy is lost through the glass itself. This is where low E glass comes in.
What is Low E glass?
It is essentially a standard clear glass with a microscopic clear coating on its surface that reflects heat better than the glass itself, creating a low emissivity composition. Low E coated glass retains heat in your home by reflecting most of the heat back into your home, and can stay cool by reflecting solar thermal energy from the outside.
Types of Coating
This coating can be either "soft" - applied to glass in an autonomous mode in a vacuum chamber at room temperature and sealed inside the glass unit, or "hard coating" - which is fused onto the glass surface during its production. ... For the purposes of this article, we will focus on soft flooring as it has a lower emissivity and is more commonly used in the UK market.
How to Get the Right Low E Glass
If you are looking for the best products, youa re exactly in a right place! Windows with Low-E glass from our company are with constant high quality indicators, accuracy and responsibility of experienced professionals, as well as a guarantee!
Low-emissive glass minimizes amount of infrared and ultraviolet light that gets inside. They also let in less heat. Yet it does not decrease amount of light itself. This is achieved with a thin coating on Low-E glass.
