What Are Low-E Glass Windows?
Low emissivity glass, or “low e glass” for short, is a specially-coated glass that has a film on it to enhance the glass’ energy efficiency characteristics. So, a low-e glass window is a window that incorporates this special glass to maximize energy efficiency.
Low-e glass comes in two varieties: “Passive” and “Solar Control.” These two coatings work in near-opposite ways. Passive low e glass coatings actually reflect sunlight into the home to make it warmer. In northern states with colder climates, this would be good, but it’s not great in Florida. Solar Control glass reflects sunlight away to prevent heat transference, keeping your home cooler.
What to Know about Low-E Glass
Want to know more about Low E glass? From how to spot a low-e window to how to care for one, here are a few things every Riverview homeowner should know:
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.
Low-E Glass Helps Reduce Your Energy Costs
Because Low-E windows help reflect away hot UV and infrared light from your home, your air conditioning doesn’t have to work as hard. This, in turn, helps you reduce your monthly AC costs.
Energy Star Requirements and Low E Windows
Low-E coatings are not a requirement for Energy Star, per se. However, they are a common feature of Energy Star-compliant windows and doors because they improve SHGC.

I reached out to Karoly for new sliding windows in my florida room and two exterior doors. Karoly came out and spent quite a while getting all the measurements right. That makes you feel good. When the installers came out, two days and done. Windows look great and the doors are solid and close tight. Everything is now impact and hurricane rated. I got my insurance discount. Thanks Karoly!+0Posted on Google![]()

I am very hard to please as I pretty much expect close to perfection. From a serious point I just want a TEAM that cares and gives it their best. Mistakes happen. However today I had Hurricane windows placed by Karoly. Actually from the very beginning it was like dealing with a family. In all my dealing with different companies A/C etc they far outshined any company I have ever dealt with. My techs were Vili, Zoli and Christian. They gave 150%, were very clean, cared about our house and did exquisite workmanship. 1,000% incredible and guess what they are not my relatives. LOLPosted on Google![]()

I will never be able to brag enough about how superior this company is. My husband and I interviewed at least seven window companies, all full of similar products of PGT or other hurricane safe Windows. We became window experts on our own with the knowledge we absorbed comparing apples to apples. Karoly was the final company we met with and Austin presentation was simple and he showed us a sample and did all the measurements. He explained the Simonton brand very well and the warranty they offer cannot be beat. We visited their showroom and met with Jesse to really look at products. Our decision was quick and easy and the price was better than their competitors. We completed all the paperwork with Richy and Angela and the rest of the wonderful staff. Installation day came and we met the fantastic installers that were so kind and clean. In 3 days our job was done. The day after that inspector came and passed us and one week later Karoly came back to complete final installation of some parts and now it’s all finished. These windows have changed our home completely. Not only did we work with the best contractor and save money we also gained a more beautiful home and it’s so quiet! No barking dogs or loud traffic or thunder anymore just peaceful tranquility!!! Thank you everyone at Karoly for making us so happy!!! I promise to call you again for all my other houses!! This was the best thing we’ve ever done without a doubt . Sincerely, Cheryl & Doug Sigmon+2Posted on Google![]()

Thrilled with our new windows and doors. Dealing with Karoly, from no pressure sales, installation, and close out was great. They kept us informed and did everything they said they would. Highly recommend Karoly Windows and Doors!+0Posted on Google![]()

After researching a few companies, I decided to go with Karoly. They replaced 19 windows and 3 sliders with Sinomton Stormbreaker Plus 300VL and Simonton Maxview. I enjoyed reading the information they had on their website and pleased to see this is a family owned business with emphasis on quality work and customer satisfaction. Employees were pleasant and professional and answered my questions. It has only been almost 2 years since installation and from my experience thus far, I would highly recommend Karoly.Posted on Google![]()

I couldn't be happier with my experience with Karoly Windows & Doors! They replaced all of my windows along with two doors, and the entire experience exceeded my expectations. From start to finish, everyone was professional, friendly, and truly cared about doing the job right. The installation crews were outstanding. They were hardworking, respectful of my home, paid attention to every detail, and the quality of their workmanship was exceptional. I'm extremely pleased with the quality of the window replacement, the beautiful new doors, and the finished results. I was so impressed with the company that I've already recommended Karoly Windows & Doors to several of my neighbors. It's refreshing to work with a company that delivers exactly what they promise. If you're considering window replacement, I highly recommend Karoly Windows & Doors. They are a true first-class company, and I couldn't be more satisfied with the entire experience.+1Posted on Google![]()

Low-E Glass Windows FAQs
What’s the Downside of Low-E Glass Windows?
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. To that end, we advise avoiding ammonia-based cleaners and other harsh cleaning chemicals.
When cleaning your low-e windows, use a lint-free microfiber cloth and wipe the glass gently to avoid damaging 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.
Impact windows already have two or more panes of glass and other protective materials. Adding a low-e glass film to these windows would help you get the best possible insulation for your home to keep it cool in the Florida heat.
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.
Or, you may even want to get a low-e coating that maximizes the reflectiveness to enhance your privacy. It’s your choice. This is why Karoly works with multiple manufacturers to source windows that meet all of your preferences as closely as possible.
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. This is especially true in multi-layered glass windows and doors where the coating is on an interior glass pane.
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.
In general, using a soft, lint-free microfiber cloth with a mixture of 10:1 mix of water and vinegar should be safe for cleaning low-e coated windows. Also, when dirt or other materials accumulate on the glass, it’s a good idea to clean it right away rather than letting it set in.
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 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.
When shopping for low-e windows in Florida, it’s important to look for the solar control type of low-e glass. The passive coating is likely to make your house warmer, which would make your AC have to work harder.
Normally, window manufacturers selling in the Florida market will be offering solar control film-coated glass windows when they talk about their ‘low-e glass’ coatings, but it’s important to verify, especially with companies that serve multiple markets.
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.
Low-E Glass vs Clear Glass: Which Is Better?
In terms of energy efficiency, low emissivity (low-e) glass is clearly better than regular glass. It blocks out the UV and infrared light rays that make your house hotter, which means your AC system doesn’t have to work as hard to keep your home cool.
Clear glass lets in the light and the radiation that makes your home hotter. If you want to keep cool, then your air conditioning system will need to work harder to maintain a comfortable temperature, raising your energy costs.
In almost all other aspects, Low-e and clear glass are the same. The only ‘advantages’ of clear, untreated glass are its lower initial cost and its clarity. The first will be offset over time as your home energy consumption is reduced by the low-e coating and the latter is a matter of pure personal preference.
For almost every Florida home, we would strongly recommend low-e vs clear glass windows for the long-term savings they can provide.
