How energy efficient are Marvin's Essential Windows?

When looking for replacement windows, you not only want them to match your style and look good, but you also want to be sure they will protect your home.

When it comes to energy efficiency, technically it measures how much ultraviolet light penetrates the glass and how much heat passes through. We will define these terms here.

UV portion

It measures the percentage of UV rays that penetrate through the window.The lower the UV level, the more UV rays will pass through and make your house warmer. UV rays are divided into three categories: UV-A, UV-B, and UV-C.

According to the International Ultraviolet Association, "ordinary glass (such as that used in windows) transmits ultraviolet radiation up to a wavelength of approximately 330 nanometers (nm) (UV-A)" and blocks almost 100% of UV-A rays through the window. Below 330nm it blocks the most damaging UV-B and UV-C rays.

The Marvin Essential window has 4% UV radiation, which means that only 4% of UV rays penetrate your window.

infrared percentage

This is the percentage of infrared rays that penetrate through a window.Britannica defines infrared rays as "that portion of the electromagnetic spectrum that extends from the red or longwave end of the visible light spectrum to the microwave region."

These rays of light are invisible to the naked eye, but they generate heat like any other ray in the electromagnetic spectrum.

The Marvin Essential window has 0% infrared.

Solar Heat Gain Coefficient (SHGC)

This measures the amount of solar heat entering through a window, ranging from 0 to 1.The US Department of Energy's consumer resource, Energy Saver, says that the lower the SHGC, the less heat from the sun entering through a window, helping to keep your home warmer during a hot summer (and fall and spring if you are in Texas). Cold. .

With a low SHGC, your windows also won't radiate as much heat as they would with normal glass.

The Marvin Ultimate window has 0.27 SHGC.

Air Infiltration Assessment

This measures "how many cubic meters of air flow through a window per minute relative to the size of the window," according to a blog post by window maker Marvin.They recommend values ​​of less than 0.30 cubic feet per meter (cfm)/ft2 for a window.

Like heat rays coming through a window, air permeability rate has to do with insulation. The better your window is insulated, the less air will get in and out of your home at will.

The Marvin Essential window has an air infiltration rate of 0.25.

All of these measurements together ultimately determine how energy efficient a window will be.

When customizing your window, there is the option of adding additional coatings or additional glass panels to the glass that would increase the energy efficiency and insulation of your home.

Does Marvin Ultimate Windows have a good warranty?

Warranty is one of the key factors in determining the value of your new windows. You want to know if your window is covered if something goes wrong or breaks.

Marvin offers afully transferable limited warranty.Insurance coverage begins on the date of installation.

All components are insured against manufacturing defects. This means that any problem that arises because the product was not manufactured correctly is covered by the guarantee.

Damage to non-glass components, such as hardware, is covered for ten years.

Under this warranty, Marvin will repair, replace, or refund the product or window component.The way to solve the problem is in the hands of Marvin. Removal, installation, finishing, refinishing and removal costs and services are not included.


Exclusions in a warranty mean that the warranty is void if defects or problems arise from any of the following causes.The exclusions are:

  • incorrect installation

  • Lack of maintenance

  • acts of god

  • Improper moisture management.

  • Shortage of thermal energy

  • condensation

  • Corrosion

In general, including Marvin's limited warranty on window frames.Most window manufacturers offer a 20-year warranty on the frame components and a 10-year warranty on the glass. This makes Marvin a strong contender against the rest.

Our verdict: The Marvin Essential window is the best window for its durability and simple, elegant design

After reviewing the Marvin Essential window in terms of material, durability, design options, energy efficiency, and warranty, you now understand all the key features of the window and can determine if it's the window you're looking for.
