In order to understand coatings, it’s important to understand the solar energy spectrum or energy from the sun. Ultraviolet (UV) light, visible light and infrared (IR) light all occupy different parts of the solar spectrum – the differences between the three are determined by their wavelengths.
Manufactured for energy efficiency, low-e glass is designed to deliver the same visual performance as a standard window while helping keep utility bills in-check.
What is Low-E Glass & How it Works
Low-e glass is made to inhibit the amount of UV rays and infrared light that pass through a glass pane without compromising visible light transmittance. With a coating thinner than a human hair that’s nearly invisible, low-e glass keeps unwanted heat and damaging UV rays out of a space.
There are two categories of low-e glass coatings: soft and hard.
Soft coat: a thin film is sputtered — or sprayed — to a pre-cut glass sheet inside a vacuum chamber and left to harden.
Hard coat: Glass is heated to a high temperature in a chemical vapor. As the glass cools, the vapor condenses and fuses to its surface.
Standard low-e coated glass offers several benefits. By limiting UV rays from passing through, sunlight does not heat up a space as much as it would. Nor is it able to cause fading or degradation to items like furniture and carpet. At the same time, heat already inside a space is reflected back in — a bonus for heating bills during the colder months.
Enhanced Low-E Glass Types
As low-e glass may need to meet more specific demands — largely dependent on climate — there are coatings available to help you get the exact performance you’re looking for:
Passive Low-E Coating
This type of low-e glass is made to maximize solar heat gain while still limiting UV rays. For property owners, passive low-e glass allows for the sun to still heat a space. Once inside a room, the solar heat is reflected back in the space — a must for those in colder climates.
Solar Low-E Coating
Opposite passive low-e coated glass, solar low-e coatings keep the sun’s heat and UV rays outside a space. This type is typically installed in residential and commercial buildings in warmer areas. Solar low-e glass coatings are usually a darker tint.
Low-E Glass Applications
Designed for energy efficiency and unobstructed viewing, low-e glass is ideal for:
Windows
Doors
Glass curtain walls
Greenhouses
Next Level Low-E Glass Windows
Low-e insulated glass units take energy efficiency and savings to the next level.
