Low-E glass, also known as low-emissivity glass, is a type of energy-efficient glass that is designed to reduce the amount of heat that is transferred through the glass, thereby reducing energy costs. Low-E glass is a popular choice for residential and commercial buildings because of its ability to reduce energy consumption, improve comfort levels, and help protect against ultraviolet (UV) radiation.
There are several different types of low-E glass available on the market, each with its own unique properties and benefits. To help you make an informed decision when choosing low-E glass for your building project, we have prepared a low-e glass comparison chart that highlights some of the key differences between the different types of low-E glass.
1. Hard-Coat Low-E Glass
Hard-coat low-E glass, also known as pyrolytic low-E glass, is created by applying a thin layer of an inorganic metal oxide coating to the glass during the manufacturing process. This type of low-E glass is durable and scratch-resistant, making it ideal for use in high-traffic areas such as commercial buildings. However, it has a slightly lower energy efficiency rating than other types of low-E glass.
2. Soft-Coat Low-E Glass
Soft-coat low-E glass, also known as sputter-coat or vacuum-deposited low-E glass, is created by applying a thin layer of a metal oxide coating to the glass after it has been manufactured. Soft-coat low-E glass has a significantly higher energy efficiency rating than hard-coat low-E glass, but it is less durable and more expensive.
3. Double Low-E Glass
Double low-E glass, also known as dual-pane low-E glass, is made up of two panes of glass with a low-E coating applied to one or both surfaces. This type of low-E glass is highly energy-efficient and can help reduce the amount of heat that is transferred through the glass, making it ideal for use in areas that require maximum energy efficiency.
4. Triple Low-E Glass
Triple low-E glass, also known as triple-pane low-E glass, is made up of three panes of glass with low-E coatings applied to one or both surfaces. This type of low-E glass is the most energy-efficient of all the types of low-E glass, but it is also the most expensive. Triple low-E glass is ideal for use in extreme climates, where it can help regulate the temperature inside a building and reduce energy costs.
5. Passive Low-E Glass
Passive low-E glass is a type of low-E glass that is designed specifically for use in passive solar buildings. Passive low-E glass is highly energy-efficient and can help regulate the temperature inside a building without the need for artificial heating or cooling systems. This type of low-E glass is ideal for use in energy-efficient homes and commercial buildings that incorporate passive solar design principles.
In conclusion, there are several different types of low-E glass available on the market, each with its own unique properties and benefits. When choosing low-E glass for your building project, it is important to consider factors such as energy efficiency, durability, and cost. By consulting our low-e glass comparison chart and working with a knowledgeable glass provider, you can select the right type of low-E glass for your building project and enjoy the benefits of improved energy efficiency, comfort, and UV protection.
