Benefits of Low-E glass windows
Energy efficiency
Low-E windows are some of the most energy-efficient windows out there. They can significantly reduce energy consumption by maintaining consistent indoor temperatures.
Cost savings
Although the initial investment might be higher, the reduction in energy bills means these windows can pay for themselves over time. Plus, you may be able to take advantage of tax credits for energy-efficient windows, depending on your area.
UV protection
These windows can block harmful UV rays, which helps prevent your fabrics and wall coverings from fading.
Improved comfort
Low-E glass reduces cold drafts and hot spots in a room, enhancing overall comfort.
Low E glass works because of an application of microscopic layers of a reflective coating on the glass. The “E” stands for emissivity, which allows a material (in this case, the coating) to radiate energy. So, homes and buildings with Low E glass windows are able to keep the heat in during cold winter months, and let it bounce off during warm summer months.
Think of Low E glass like the silver lining inside a thermos. When warm items are inside, heat bounces off the silver lining and reflects back inside the container to keep contents warm. This would be just like heat inside your home during the cooler months of the year. And, the opposite applies when you have cold items inside the thermos - heat doesn’t penetrate through the silver lining. So in the summer months, the outside heat can bounce or reflect off the Low E glass window, keeping your home cooler and reducing overall cooling costs.

Types of Low-E Glass
There are two types of low-e coating
Passive low-e coating
Designed to optimize energy efficiency by reducing the amount of heat that is lost through a window. Passive low-e glass has a higher emissivity rating than solar low-e glass, which means it is better at reflecting heat back into a room. It is typically used in colder climates where reducing heat loss is a priority.
Solar control low-e coating
Designed to reduce the amount of heat that enters a building from outside, making it ideal for use in warmer climates. It has a lower emissivity rating than passive low-e glass, which means it is better at allowing solar radiation to pass through the glass while reflecting back a smaller amount of the radiant heat from the sun. By reducing the amount of heat that enters a building, solar low-e glass can help reduce cooling costs and improve comfort levels inside the building.
