Are you looking for an energy saving glass for your windows? Why not consider a glass that reduces heat transfer and saves cost? By installing a Low E-glass, you fulfill both goals.
Low E-glass or low-emissivity glass emits a low level of thermal energy. It decreases the overall lighting, heating and cooling costs by maintaining a comfortable temperature inside your home. It comes with an invisible coating that minimizes heat transmission.
How Does It Work?
The word emissivity in low-e glass stands for the ability of the material to radiate energy. To be energy-efficient, window glass must have low emissivity.
Scientifically, the low-e coating decreases the amount of ultraviolet and infrared rays to enter and allows the visible light to pass through. In simpler terms, the coating on low e-glass restricts the entry of outside heat inside your house during the summer. During the winter, it doesn’t let your home’s warm air escape; it helps in maintaining a comfortable indoor environment.
Types of Coating
There are two types of low-e coatings, solar control and passive. Glass with solar control coating is manufactured by using the Magnetron Sputtering Vapor Deposition (MSVD) process. In this process, metal particles are deposited on the glass surface inside a vacuum chamber at room temperature. This coating is also known as a ‘soft coat’. The coating has lower emissivity and superior solar control performance.
Passive coating glass is manufactured through a pyrolytic process. In this process, a film coating is applied on the glass surface at a high temperature while the glass is on the float line. This coating is also known as a ‘hard coat’ and is very good for places with a cold climate.
Why Buy Low-E Glass?
Low-E glass performs better than standard clear window glass. Since it neither lets the inner heat to escape, nor allows outside heat to enter a room, they save a lot of money on heating and cooling. The energy-efficient glass is good for house plants as well. The glass allows the necessary sun light for plant growth, while blocking other harmful rays.
While choosing the right glass for your windows, have energy-efficiency be an important factor. Low-E glass reduces your carbon footprint and cuts down your energy bill. If you want a window glass that allows light and blocks heat, then a low-e glass is your best bet.
