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:
- Glass curtain walls
Next Level Low-E Glass Windows
Low-e insulated glass units take energy efficiency and savings to the next level.
