Advantages of Low-E Storm Doors
Low-e storm doors use a thin, invisible coating that reduces the infrared and ultraviolet light coming through the door glass. In the wintertime, low-e glass lets radiant heat pass through but doesn't allow it to come back out, which means it can help retain heat within your home.

Is it worth getting Low-E glass?

Absolutely! Low-e glass options are definitely worth the investment. For just a few more dollars than standard glass, you get the energy savings and protection from low-e glass. And that little extra cost can pay for itself with the money you'll save on utility bills!

What are the disadvantages of Low-E glass?

The major disadvantage of low e glass is it is expensive as compared to normal glass. For facades, which are in direct contact with sunlight, low e glass will trap the heat radiating from objects inside, which may lead to overheating of interiors.

Does Low-E glass look clear?

Low-E is a window coating that is completely transparent. It's not the same as tinted glass, which blocks out light but doesn't reduce heat transfer.

How much difference do Low-E windows make?

Windows Still Allow Natural Light

That means you can still get plenty of natural light in your room. Low-E glass does filter out a very small amount of visible light, but you won't notice much of a difference compared to normal windows.

What Are Low-E Coatings For Windows?

How long do low-e windows last?

Weaver said that, based on what he has been told, “the newer low-e coatings are much more durable and more securely bonded to the glass than the older-generation low-e's.” He said the sealant on the glass should last five to 10 years, and the coatings should outlast that by several years.

Does low-e glass keep heat out?

Low-E glass can filter 40 to 70 percent of the heat that is normally transmitted through standard window glass. It works by reflecting heat back to its source.

Is low-e glass more expensive than clear glass?

The Low-E coating is a one-time coating that is applied evenly to the entire surface of the glass. While most people think the coating makes the glass much more expensive, the truth is the initial cost of this additional coating is typically just a couple more dollars than regular glass windows.

What does low-e mean on a storm door?

Low-e storm doors can be a simple way to increase the energy efficiency of your entry door. This makes sense because low-e stands for low emissivity, and involves using a thin, invisible coating that minimizes the amount of infrared and ultraviolet light that come through the glass.

What does low-e glass do?

Low-E coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. When heat or light energy is absorbed by glass, it is either shifted away by moving air or re-radiated by the glass surface.

Is low-e glass better than double glazing?

Double glazing has been found to be more effective than low-E glass in areas where extremes of both heat and cold exist because it reduces heat transfer from both within and without. When heating the house during the colder months, double glazing helps prevent heat from escaping the house.

What is the difference between clear glass and low-e glass?

Low-e windows do limit the visual quality of the window slightly. When compared to a clear window close up, it is difficult to see a difference. But when the windows are viewed from farther back in sunlight, the low-e coated window has a slight grayish tint.

When did low-e glass become available?

By the late 80s, window manufacturers began to use low-emissivity (low-e) glass containing a metal oxide layer that permitted visible light to pass through and also prevent heat from seeping outward. This glass was actually made with several thin layers of gold that created a green tinge.

How much does low-e glass cost?

A low-e window glass price will generally be around $14 per square foot. Additionally, in the long run, low-e coatings will help you save money on energy bills.

Does low-e go inside or outside?

The effectiveness of low-e glass is dependent on the direction the coating is facing. For single pane windows it is recommended the low-e coating is always placed on the inside facing surface. Low-e coatings are sensitive to weather and pollutants making it difficult to clean without damaging the surface.

What is high performance low-e glass?

Low Emissivity Glass, also known as Low E glass, is glass that has a coating applied to it, making windows and doors substantially more energy efficient. Originally designed to keep in infrared light for colder climates, they're now a cost-efficient option that is effective in a variety of regions.

Does low-e glass look green?

Building code requires that replacement windows include Low-E glass, which is very efficient at blocking solar heat and reducing damage from UV light. Unfortunately, Low-E glass provides a blue/green coloration to the glass that many homeowners find unattractive.

Can you use Windex on low-e windows?

Cleaning Low E Glass

Consequently it is recommended that Windex® glass and surface cleaner (clear liquid) is used as this will minimise smearing. Do not use ammonia based glass cleaners or alcohol based cleaners, as these will leave smears on the glass.

Are low-e windows good?

Low E applied to windows helps block infrared light from penetrating the glass from the outside. In addition, Low E helps keep in your heating/cooling energy. Bottom line: they are much more energy-efficient, helping you save on heating and cooling costs and costs associated with running your heating/cooling systems.

Does low-e glass scratch easily?

Why is that? The coating is actually very difficult to scratch and is harder than the glass. For example, if you scratch the coating with a coin, it is the metal from the coin you see deposited on the glass surface itself rather than a scratch.

Do low-e glass windows look different?

If the window contains low-e glass, one of the images will be a different color than the rest of the images. If the window does not have low-e glass, the four reflected images will be the same color.

When did windows become energy efficient?

During the 70's, multi-paned windows were introduced to the market, and they were more energy-efficient than other windows previously used. If you've got a home that was built prior to 1970 and have never had the windows replaced, your home most likely has those old energy-wasting windows with only one layer of glass.

What is low-e glass in storm windows?

Coated with an ultra-thin, virtually invisible layer of metal, low-e windows reflect infrared heat back into the home. This coating improves the window's insulation ability, in turn lowering your heating and cooling costs. On average, low-e storm windows can save you 10%–30% in heating and cooling costs.

Is low-e glass reflective?

Highly reflective low-emissivity or Low-E glass windows are great for the energy efficiency of your home, but they're not perfect. Low-E glass is more expensive than windows with regular glass but can help homeowners to save money on utility bills, so the investment pays off in the long run.

What does low-e stand for?

Low-E, or low-emissivity, glass was created to minimize the amount of infrared and ultraviolet light that comes through your glass, without minimizing the amount of light that enters your home. Low-E glass windows have a microscopically thin coating that is transparent and reflects heat.
