What Is Low-E Glass?
Low-E glass is a shorthand term for “low emissivity glass,” which is a special type of glass that uses a coating to improve the glass’ thermal efficiency by blocking nonvisible light (such as UV or infrared light) from getting through. This helps make the glass itself better at insulating your home.
About Low-E Glass in Tampa
Low-E Glass May Have a Noticeable Tint
Many forms of low e glass coatings may have a slight tint or reflective appearance, making them easy to identify. However, there are some manufacturers who offer near-invisible low-e coatings.
Passive Low-E vs Solar Low-E Glass
There are two kinds of Low-E glass: Passive and Solar Control. Passive glass actually increases solar heat gain, which is bad for Tampa homes. Make sure you get Solar Low-E glass.
How to Take Care of Low-E Glass
When cleaning low e glass, it’s important to avoid harsh chemicals like ammonia or using abrasive wiping tools. Use soft, lint-free cloths with water or a mild glass cleaner formulated for gentleness.

Tampa Low-E Glass FAQs
What Is the Downside of Low-E Glass?
A lot of consumers wonder “what’s the catch?” when they hear about the energy efficiency benefits of using windows with a low-e coating.
The biggest ‘downside’ to using low-e glass windows and doors is that they’ll have a higher upfront cost than identical windows and doors that don’t have the special coating. However, this ‘disadvantage’ is more than balanced out by the long-term savings that installing energy-efficient glass windows and doors can have for a Florida home.
The other downside is that, because the low emissivity properties of this glass is due to a coating, special care needs to be taken to protect the coating. Avoid using ammonia-based cleaners that may strip the coating.
Which Is Better: Double-Paned Glass or Low-E Glass?
When measuring energy efficiency, a lot of window buyers wonder what provides the biggest bang for their buck: low-e coatings or multi-layered glass windows.
Having two panes of glass (especially with an inert gas fill like argon gas) does a better overall job of insulating the home from outside temperatures. However, low-e coatings are specifically better at reducing solar heat gain for the cost.
In Florida, that would make low-e glass the better overall option… but why not maximize energy efficiency and do both? You can have both low-e glass and multiple panes of glass to make your home as energy efficient as possible.
Does Low-E Glass Look Different?
In many cases, yes. While Low-E glass doesn’t block natural light, the coating may give the glass a tinted or slightly reflective appearance. However, some manufacturers specialize in providing near-invisible low-e coatings that don’t impact the appearance of your windows.
How Long Do Low-E Glass Coatings Last?
In most cases, with proper care, a low-e glass coating on a window should last for as long as the window itself. On multi-layered glass windows and doors where the coating is on an interior glass pane, it should last until the window itself fails.
However, improper care can damage the coating. For example, using strong ammonia-based glass cleaning solutions and rough tools to wash the window may strip the coating if touched directly. Be sure to consult with your window installer to get proper care advice for your new windows.
Are There Different Types of Low-E Glass?
Yes. There are many different types of low e coatings for glass from different manufacturers. Some specialize in maximizing energy efficiency, others in making the glass look as clear as possible.
Also, there are two different varieties of low e coatings to know about: Passive and Solar Control.
- Passive Low-E coatings actually maximize the amount of solar energy being transferred into the home, reflecting warmth back inside to heat the house up. This is the kind of coating that would be used in more Northern climates where temperatures are typically lower for most of the year.
- Solar Control Low-E coatings reflect solar heat to keep it outside the home to keep it cooler throughout the year. This is the type of low e coating most often used in Florida since ours is a more tropical climate.
How Much Does Low-E Glass Cost?
The answer depends on the size of your window, the manufacturer, and the grade of low-e coating applied to your window. Adding a specialized coating will increase the cost of your new window or door.
For more specific pricing information, you would need to speak with a window installation expert who knows the size and style of window or door you’re looking to install.
Will Low-E Glass Meet ENERGY STAR Requirements?
Energy Star v7.0 has some strict requirements for windows, doors, and skylights. Using low-e glass in your window or door can help it meet these requirements, but that alone doesn’t guarantee compliance.
When buying new windows and doors, look at the U-Factor and Solar Heat Gain Coefficient (SHGC) figures for that product to see if they meet the program’s requirements.
For windows in the southern U.S. to meet Energy Star v7.0 standards, they must have a U-factor of 0.32 or less and an SHGC of 0.23 or less. Door requirements would be 0.50 or lower U-factor and 0.25 or less SHGC.
Look for the ENERGY STAR mark on the product and verify it through the Energy Star product finder page.
