Don’t Replace Your Old Windows With Low-E Glass (Here’s What You Can Do Instead)

Don’t Replace Your Old Windows With Low-E Glass (Here’s What You Can Do Instead)

Imagine losing $1000 from your income every single year.

For most American households, that’s roughly how much it will cost to heat and cool their home for the year.

That adds up, especially when every dollar counts.

It’s no surprise that people are looking for ways to save on energy costs.

Typically, windows are the worst energy culprits on any given house.

Heat gain and heat loss through windows account for between 25%-30% of a home’s energy use for heating and cooling.

If a window has failing seals, it will perform even worse.

Even the type of the window frame can affect energy performance.

If the window frame is made from a material that is a poor insulator, such as aluminum, it can create what’s known as a thermal bridge and conduct heat from inside the house to outside. 

One inefficient window can lose as much heat as 10 to 20 times what an insulated wall would lose.

Even if your window is new and well sealed, it could still be the cause for a lot of energy use in your home.

Solar energy is still able to pass through glass, so even an insulated window can heat up a room quickly if it gets a lot of sun.

In the dead heat of summer, having even just one window or skylight that gets a lot of sun exposure can mean the AC is running all day just to cool the room off.

So What Can Be Done?

The most common recommendation to make old windows more energy efficient is to replace them entirely with new, low-e windows.

Low-e windows are windows that have been treated with a film that reflects solar heat while still letting natural light pass through.

With less solar heat entering the home, the AC no longer has to work as hard to keep the house cool.

The less energy the AC uses, the more savings there are for the homeowner.

Is replacing old windows with new ones worth the cost?

There will be energy savings from replacing old windows with new, low-e glass windows but it comes with a substantial upfront cost.

The National Association of Realtors estimates the cost of replacing every window in a 2,450 square foot house to be around $19,000.

For a household trying to save money in energy bills, that’s a very large investment with a slow return.

What are some more cost effective alternatives to replacing an old window?

The most important thing to do with old windows is stop any exchange of air between the inside and outside of your house.

For drafty windows, using a product like rope caulk to seal up any holes can make a major improvement.

Plastic film insulation is another popular and effective solution for sealing up older windows.

Both options are inexpensive and simple enough for anyone to apply.

For windows that get a lot of sun exposure, a quick and easy way to make them more energy efficient is to mount exterior shade mesh on them (also called shade screen or solar screen/mesh/fabric).

There are a lot of different kinds of shade mesh available, but they all work by the same principle.

It’s a mesh fabric, and like low-e glass, it works by blocking solar heat and light, while still letting natural light through.

Unlike low-e glass, which is a film that’s been applied to the glass, solar mesh is installed on the exterior of the window.

Applying the shade screen to the outside of a window is key for it’s ability to keep a room cool.

If it’s applied to the inside of a window it will still work but not nearly as well.

If it’s mounted on the inside the screen will still provide shade from the sun, but the energy savings will be significantly less because the heat will be trapped inside the house.

If you are considering shade screens for your home and don’t know which one to choose, the easiest and best option is EZ Snap.

They sell do-it-yourself kits that let you mount and cut your mesh to your window, no matter it’s size or shape.

EZ Snap is also a fraction of the cost of what you would pay to buy and install new windows.

You save on the price of the product, and because you are able to install it yourself, you save on labor as well.

EZ Snap shade screen is also better at blocking solar heat than low-e glass.

The effectiveness of heat blocking applications for windows is measured by the Solar Heat Gain Coefficient (SHGC).

The SHGC is the amount of solar radiation (heat) that transmits through a window.

It’s measured between 0 and 1, and the less solar heat that transmits through a window, the lower a window’s SHGC number is going to be.

There are a lot of low-e glass makes and models, but the range of SHGC for most of them from varies between 0.60 – 0.25. 

Shade mesh from EZ Snap has a SHGC of .18.

Something else to consider is that low-e windows are known to damage turf and siding.

In the right conditions, the solar heat that they reflect can focus into a hot spot creating a magnifying glass effect that melts anything in its path.

The problem is becoming so rampant with the rising popularity of low-e windows that one scientist is calling them, “the next asbestos.”

If you or your neighbor has a low-e window that is damaging property, EZ Snap is also the ideal solution.

Rather than replace the entire window, installing EZ Snap window shade over the problem window provides a fast and effective fix.

The solar heat is reflected off of the mesh before it ever reaches the window, preventing any chance of a hot spot forming.

The result is 100 percent effective and can be installed in as little as an afternoon.

An added benefit to an exterior shade product like EZ Snap is that it’s also removable. So, when the winter months come you can take it off and benefit from the natural heating you get with the sun.

It’s like getting free heat in the winter.

No matter which window option you choose to make your home more energy efficient, it’s important to do your research before making a final decision. 

You want to make sure that you are going to be getting the maximum return for your investment.

Replacing your windows might be worth the cost, or it might make more sense to invest in solutions that are able to make your existing windows more energy efficient.

 

Is Your Artificial Grass Melting? The Cause And The Solution

Is Your Artificial Grass Melting? The Cause And The Solution

Is your artificial turf burning or melting?

It’s becoming an increasingly common problem for many homeowners.

If you are finding streaks of your turf melted and discolored, the culprit is most likely a nearby window that has something called low-e glass in it.

Illustration of how low-e glass windows work.

Low-e glass is glass that has been treated with a type of energy efficient coating. The glass is coated with a microscopic, transparent metallic layer that reflects heat, but still allows light to pass through.

These windows are good at cutting down the amount of heat entering a house, which is why more and more homes are being built with them installed. However, they can also act like a giant magnifying glass.

Low-e windows are all double paned, and when there is a difference in pressure between the outside air and the interior of the glass panes, the windows may slightly warp and bend. This can create a concave effect in the glass.

This concave effect, coupled with the reflective low-e coating, can focus sunlight into a concentrated hot spot, just like you see with a magnifying glass.

The temperature of these hot spots can get so high that they destroy anything they touch.

It’s increasingly common for these low-e windows to melt synthetic turf, vinyl siding and even cause natural grass to catch fire.

Fake grass will begin to melt at around 175 degrees Fahrenheit. We recently had a customer write to us to say that his turf was melting due to a low-e window. He took a reading of the hot spot that was destroying his lawn and it was over 190 degrees.

If a large enough patch of turf has been melted, it will need to be replaced. Since artificial turf can cost anywhere from 5 – 25 dollars a square foot (not including labor), replacing damaged turf is a costly and time consuming process.

As more and more homes are getting low-e windows installed, so are the amount of people finding their turf being damaged. Even if you don’t have low-e windows your lawn may still get scorched.

If you are seeing signs of damage to your turf and don’t have low-e windows on your house, the cause may be one of your neighbors windows.

What can be done about Melting Turf?

First, know that if you take the time and money to replace your lawn but don’t address the cause, it’s just going to happen again.

A simple solution would be to put something up, such as a patio umbrella, to protect your turf. This would only be a temporary fix though, because anything you put in the way of the hot spot will only get destroyed.

What needs to happen is for the sun’s rays to be blocked before they can hit the window and reflect back out. If the solar heat is cut down before it ever touches the glass, then there is nothing to reflect out and your lawn is safe.

Fortunately, EZ Snap Shade Screens are the ideal solution. They can be installed right over the problematic low-e glass window quickly and easily, and for a lot less than it would cost to replace the entire window.

EZ Snap Shade Screens are proven to stop up to 90% of the sun’s rays from reaching the glass. You get all of the cooling power of a low-e window, but without the risk of creating hot spots.

They are easy to order and can be installed by someone with no previous experience.

One of the reasons why low-e glass is so popular is that it blocks heat while still allowing light to shine through. What’s great about EZ Snap is that it uses an optical grade mesh, meaning EZ Snap blocks the heat but not the view. The screens are also guaranteed to fit all window sizes and shapes.
