Save Energy

Have Energy Efficient Windows Without Replacing Existing Windows

Energy Efficient Windows Added

Air Leak Test Conducted

With Mr. W.’s permission, after adding our energy efficient windows to his existing windows, his home was tested by Sierra Energy Professionals to determine the amount of air leakage.

Sierra Energy Professionals found that Soundproof Windows act as energy efficient windows, by significantly reducing the amount of air flow leakage and infiltration.

Quality of Life Improvement from Energy Efficient Windows

Mr. W. knew about the soundproofing features of the windows, but had no idea this kind of improvement in energy savings could be experienced without replacing his existing windows:

“The addition of your windows to our home has been a phenomenal success for soundproofing and saving energy.

We live in the middle of a downtown casino and hotel district that is extremely busy with traffic and special events, and really needed soundproofing.

Before these windows were added to our existing windows, you could easily hear the conversation of every couple walking down the street, every car with a premium sound system sounded like it was in the living room with us, and special events were a nuisance. Now, we hardly even know there is ever a car, person or event outside.

Every winter was frigid in the house while the furnace ran continuously to keep up. If you stood near a window you would freeze. After adding your energy efficient windows, our energy bill has been cut in half and our winter can be spent cozy and warm in our home.

Even more important to me than the energy savings and soundproofing, was that the comfort level inside my home changed from being very uncomfortable to amazingly relaxing and peaceful.”

Saved 49.7% on Energy Bill for Entire Winter

Mr. W. provided us with the energy usage and costs from his actual utility bill over two winters, which showed an incredible 49.7% savings on energy bills, as well as a 54.5% decrease in fuel consumption over that same time period.

“Here are the fuel consumption records I have for my oil furnace before installing your energy efficient windows and afterwards. I am sharing this information with you because I think everyone should hear about your important product.”

Before Adding Energy Efficient Windows:

October 2007 to March 2008 (Winter)Year Total: $1978.00
Date Description Energy Cost
Oct. 15, 2007 150 Gallons Heating Oil 565.00
Nov. 21, 2007 100 Gallons Heating Oil 383.00
Dec. 4, 2007 100 Gallons Heating Oil 350.00
Jan. 4, 2008 100 Gallons Heating Oil 345.00
Feb. 12, 2008 100 Gallons Heating Oil 335.00
Year Total: $1978.00


After Adding Energy Efficient Windows:

October 2008 to March 2009 (Winter)
Date Description Energy Cost
Oct. 15, 2008 100 Gallons Heating Oil 385.00
Jan. 7, 2009 100 Gallons Heating Oil 343.00
March 13, 2009 100 Gallons Heating Oil 255.00
Year Total: $983.00

“As can be seen above my overall energy usage for the winter of 2007/2008 was 550 gallons for a total of $1978.00. During the 2008/2009 winter season, I only consumed 300 gallons of fuel for a total of $983.00. This is a $995 savings from the prior year, and 250 gallons less heating oil used!

Not only did I consume less fuel and use less energy, but as can be seen above I filled up approximately every two months as opposed to every month.”
