Indow window inserts are an innovative way to insulate your home while still preserving the charm of your original windows. The inserts, completely transparent, simply press inside the window frame. And — because our specialty is making window inserts for historic homes, where most windows are slightly out of square — we custom every window insert is custom made to be a precise fit for your unique windows.
Seattle Case Study
Aileen was on a mission to boost her historic home’s energy efficiency. She got rid of her oil furnace and electric baseboards. She air sealed and insulated. She even participated in an energy efficiency study by the US Department of Energy. But she wanted to go further and the one element that remained unaddressed in her historic home energy efficiency project was incredibly important: her windows.
Aileen began searching for window efficiency ideas and was impressed when she learned that Indow windows inserts could provide as much comfort and energy efficiency as high-end replacement windows. She decided to put Indow inserts in 27 of the single-pane windows in her 1916 Seattle home. And it’s made a world of difference.
Historic Home Energy Efficiency Made Easy
A follow up study for the U.S. Department of Energy prepared by the Pacific Northwest National Laboratory found that the Indow window inserts reduced her heating, ventilation and air-conditioning energy use by more than 20%! She would have had to have gotten high-end double or triple-pane windows, at great expense, to achieve that level of savings.
“My point is that you can take a 100-year-old historic home and by doing some effective things, you can make it as energy efficient as a new building,” she said.”
And that’s important when you consider that energy use in residential homes has increased to 22% of total energy use in the United States. Reducing energy loss through windows is one of the most important steps individuals can take to address climate change.
Additional Benefit: Window Soundproofing
Not only did it do that and lower her energy use, but it had the unexpected benefit of making her home much quieter.
“The biggest difference I noticed was the sound reduction,” she said. “I’m on a residential street but you get a whole lot of noise penetration with single-pane windows.”
With all the energy efficiency work taken together Aileen has seen her energy bills drop from more than $300 a month to $27 a month. “I’m trying to reduce our impact on the environment to save the environment.”
