Energy costs are a major concern for homeowners, especially those in the Western United States. That makes sense when you consider that, on average, Californians still pay 40 percent more for electricity than the national average. That’s despite the state’s heavy investment in renewable energy. When you live in the sunshine-drenched Golden State, you need options to save on energy. That’s where low-e glass windows come in.
These windows can help you save money on energy costs. They also protect the interior of your home in the process.
Read on for more reasons why you need US Window & Door to install low-e glass windows in your home.
The Lowdown on Low-E Glass Window
First of all, what exactly is Low-E glass? Low-e—or low emissivity—glass windows have a special coating that forms a barrier between the sun and your home. It works by blocking certain wavelengths on the electromagnetic spectrum.
These windows allow visible light to pass through while blocking two of the sun’s most destructive rays: UV and IR radiation.
UV, or ultraviolet, radiation is a particularly destructive emission. It’s the reason we tan or burn outside. It’s also the catalyst for skin cancer.
IR, or infrared, light is heat radiation. This emission is responsible for the overpowering warmth we feel coming off of the sun in the heat of the day.
With these windows, you can stop both of these damaging rays from entering your home.
Why You Need Low-E Glass Windows in Your Home
They Block Harmful UV Radiation
UV radiation has been famously shown to cause all manners of damage to the human body. Prolonged UV exposure is responsible for sunburns, skin cancer, and even permanent eye damage.
It doesn’t just have a negative effect on our bodies, though. UV radiation also has the power to damage your furniture and home’s interior by causing fading.
If you’ve ever left an object outside for a prolonged period of time, you’ve likely seen fading occur. Depending on the material, you may have even seen cracks develop as the object became brittle and dry. That’s UV radiation at work.
Low-e windows help stop this process. They block out enough of the sun’s UV radiation to keep your furniture and decor protected from its damaging effects.
You can keep your home’s interior protected without the need for heavy shades or fussy furniture covers.
They Keep the Heat Out
Because low-e windows block IR radiation—the sun’s main carrier of heat—they can keep extra warmth from entering your home.
By restricting the movement of IR radiation, these windows actually impact heat flow. That means that physical warmth has less of a chance of entering your home from the outside.
They can keep heat from leaving your home, too. On those rare cool days when you want a little extra warmth, your windows can save you from wasting your heater’s efforts.
They’re Energy Efficient and Can Save You Money
One of the biggest draws of low-e windows is their potential to save you money. Because they are so good at stopping heat transfer from your windows, they have the ability to save you big on your utility bill.
In fact, depending on the how energy efficient your current windows are, these windows can save you between $800 and $1,300 on energy costs over your lifetime.
That all goes back to heat flow. Low-e windows are so well-suited to mitigating heat flow that you’ll see their money-saving effects immediately.
You’ll no longer have to crank your a/c down to make up for the heat coming in through your windows.
If you combine low-e windows with other energy-saving modifications, you’ll maximize the control you have over the temperature of your home.
You Won’t Have to Sacrifice Your View
According to the old adage, what’s the most important aspect of real estate? Location, location, location.
That’s why many homeowners have traditionally avoided installing solar film screens on their windows or investing in blackout shades or blinds. These treatments do a great job of blocking the sun, but they cost you your view in the process.
Low-e windows skip that problem entirely. Because their special coating has very little effect on the visible light spectrum, they perform their heat-blocking duties without muddying your view.
These windows won’t make your home appear darker. You won’t have to wrestle with any restrictive window coverings every time you want to look outside.
Low-e windows might just offer your best chance of enjoying your beautiful California surroundings without dealing with the negative effects of the relentless sunshine.
Consider These Points Before You Buy
The benefits of these windows are seemingly endless, but there are a few points you need to consider before you decide to add them to your home.
You’ll Need to Buy New Windows
That’s because the coating that gives low-e glass its name can only be applied during the manufacturing process.
You can’t apply it to the windows that are already installed in your home.
You Have Different Types to Choose From
When you are shopping for low-e glass windows, you have two varieties to choose from: soft coat and hard coat.
With hard coat windows, the energy-efficient coating is applied directly to the glass while it’s still slightly molten. It creates a durable outer reflective layer to the window that can stand up to harsh environmental conditions.
These windows will sometimes have a slight tint visible from the outside. soft coat windows, the coating layer is much less durable. To protect it from environmental damage, it is usually sandwiched between two panes of insulated glass.
Soft coat windows tend to be better at reflecting heat and keeping your home cool. Their additional insulation makes them more energy efficient, too.
You May Need to Be Careful How You Clean Them
If you opt for a soft-coat model, you should be able to clean your windows as you normally would.
That’s because the special coating is protected on either side by panes of glass. Unless you break your window, you won’t be able to reach the delicate reflective layer inside.
If, however, you choose hard coat windows for your home, you’ll need to take special care to avoid damaging the reflective layer when you clean.
That means no abrasive cleaning tools and no ammonia-based window cleaners. While hard coat windows are durable and meant to resist scratching, it’s a good idea not to test it.
If you have questions about how to take care of your new windows, your installer will be able to help.
Angled Windows May Present a Problem
It’s a very rare concern, but if your home has any angled or concave windows, low-e glass might pose a problem to any plastic or vinyl objects in their vicinity.
That’s because the low-e coating is actually reflecting UV and IR radiation when it blocks it from entering your home. If the angle is just right, it could focus and bounce these rays onto a nearby object and cause some heat damage.
It’s the same phenomenon that can turn a magnifying glass on a sunny day into a tiny heat ray.
This risk doesn’t cause problems for most homeowners. If your windows are upright and flat, any reflected UV and IR radiation should bounce back harmlessly.
If, however, your windows are set at an angle or bowl-shaped, you should consult a professional for advice on how to prevent hot spots around your home.
