Resized Marla YorstenHave a painting you love that gets light from your windows?

Marla Yorston did. She hung it prominently over the fireplace in her living room with its arched windows that extend into a vaulted ceiling. Here, the light makes the painting a focal point of the room in her Hickory Creek home outside Dallas. But then she noticed something: that light was also beginning to damage the artwork and Marla detected a light smokiness to the paint along the bottom of the canvas.

“It doesn’t have the same pop,” she said of the sun damage. 

The windows, a main reason she bought the home, weren’t just destroying her painting. They also threatened her leather furniture, which she didn’t want to crack prematurely.

So Marla took action. Not one for window tinting, she considered honeycombed blinds and a decorative metal grill with a sunscreen. But then she realized her family would no longer be able to see the stars and moon through those windows at night.

“I don’t want the sun to massacre my stuff,” she said. “But I want my windows just the way they are.”

Then a friend told Marla about Indow Windows. She called Daylight Rangers in Plano who laser-measured the living room windows for Museum Grade to block the UV light damaging her painting. With Indow’s proprietary laser-measuring system, it’s possible to handcraft inserts that precisely fit special geometries like Marla’s arched windows. She bought Acoustic Grade to quiet the bedrooms.

“They look beautiful,” she said. It’s most noticeable at night, but the Museum Grade inserts improve the windows’ appearance by covering the interior metal frame and making them seem as if they’re trimmed in wood.

Not only did Marla protect her painting protected, but quieted her house. She can’t hear traffic and if a motorcycle rumbles by on Interstate 35 it’s so muffled, it doesn’t wake her.

Go Marla!


photo (23)Maybe it’s oxymoronic, but “Less is more,” first written by Robert Browning, can’t be said enough. Less bought at the store or online means less in the landfill. Less driving means more stability for the climate. The less energy used, the more there is to go around.  The Pacific Northwest has implicitly understood the latter for some time. Take the Northwest Energy Efficiency Alliance: since 1997, the energy saved through NEEA initiatives is enough to power 700,000 Northwest homes annually!

It’s important to develop renewable energy sources but the cheapest, easiest way to get more energy now is for all of us to do our best to use less of it. And that includes everything from turning off lights to making homes more energy efficient. Clean Energy Works in Oregon, which helps homeowners make their dwellings more energy efficient, states that 10 houses upgraded for energy efficiency means another three houses can be powered from the savings gained.

Wondering what you can do to conserve energy at home?

You’re in luck since October is Energy Action Month! Back in 2012 President Obama declared it so, proclaiming, “A secure energy future is vital to an economy built to last . . . As demand for energy increases worldwide, our Nation must continue to lead the world in a rapidly evolving energy market by pursuing safe and responsible domestic energy production, promoting efficiency, and developing clean energy and renewable fuels.”

Increasing the energy efficiency of the built environment is what Indow is all about. During the U.S. Department of Energy’s Energy Action Month, find suggestions for ways to make your life more energy efficient today, this month and this year.

A few things you can do right now:

  1. Turn down the temperature of your water to the warm setting (120°F) Review additional strategies to reduce your water heating bills. Water heating can account for 14-25% of the energy consumed in your home. 
  2. Since heating can account for nearly half of the average family’s winter energy bill, call a furnace or heat pump professional to service it each year.
  3. Clean or replace filters in your furnace, air conditioner, and heat pump.


A few larger projects to tackle this year:

  1. Seal up the largest air leaks in your house
  2. Insulate
  3. Upgrade leaky windows. (Indow inserts are made to do just that so your home is more comfortable and energy efficient this winter. Learn more about what they can do for you!)


This continues a series of profiles we started last year on Indow employees . . . 

Myo resizedMyo cuts tubing on the Indow factory floor, a job that requires precision and patience.

He reads the laser measurements of people’s window frames sent from around the country and cuts the silicone compression tube so that each insert fits snugly inside its respective window.

He is more than qualified, having received a B.S. in physics at Rangoon University in Burma as well as a machine tools vocational degree.

His path to Portland and Indow is long and involved.

Myo worked for an international engineering company – Cosmo Engineering – straight out of university making punches and dies, chutes and cams. But he fled his home country in 2002 for his company’s Malaysian branch after the military government began investigating his involvement in the 1988 university student protests.

“We need democracy and freedom,” he explained. “The students need to protest.”

It wasn’t safe for him in Malaysia either. In 2012, the United States granted his family refugee status and he moved with his wife and two children to Texas. There he worked and saved until his family could move to Portland to be closer to friends and take advantage of a good public transportation system. He takes TriMet from his home near SE Division and 82nd to work on North Interstate every day.

“Everyone works together and cooperates – we give each other a helping hand,” he said of his new job.  “I want to grow Indow.”

He plans to study at Portland Community College to improve his English. Through a program with the Immigrant & Refugee Community Organization that matched his savings, he was able to buy a used car. When asked what he misses about Burma, he said, “everything”: his friends, his family, the noodle dish Moke-hin-khar, the British-style buildings from when Burma was a British colony.

But certain things remind him of Burma like the conifers in Portland, which he had in his hometown, Kalaw.

What does he like best about the U.S.?

“Everyone has human rights,” he said. “If you’re not satisfied, you can tell the government, ‘You’re wrong.’ In Burma you can go to jail.”

Freedom of expression is something we’re thinking a lot about right now. Indow helped create greater public access at Alcatraz for the groundbreaking Ai Weiwei exhibit on human rights by lining the broken gun gallery windows of the New Industries Building with inserts.  

We are happy working at Indow has helped Myo establish new roots in the United States.

@Large: Ai Weiwei on Alcatraz in the New York Times

Ai Weiwei used more than 1 million Legos to build his portraits of political exiles and prisoners of conscience in the New Industries Building of Alcatraz for his exhibit opening today. The media leading up to the opening of @Large: Ai Weiwei on Alcatraz has been sustained and glowing. The New York Times wrote, “The Chinese artist and activist Ai Weiwei is taking his vision to one of the most infamous prisons, using it as an inspiration for a monumental installation.”

We are so honored to be a part of it! Indow inserts line the broken gun gallery windows of the New Industries Building where guards pointed their weapons at the prisoners working below doing laundry or making clothes and brushes. Organizers of @Large had to shield visitors from the broken glass and protect the windows from overzealous souvenir seekers. Since Alcatraz is a National Historic Landmark there couldn’t be a nail hole or mark so the  FOR-SITE foundation turned to Indow for a solution.

Of the seven projects in the @Large exhibit, three are in the New Industries Building where Indow inserts are installed: Trace (the Lego portraits), With Wind (A large dragon kite and others) and Refraction (A giant metal bird wing).

The exhibit runs through April 26. Learn more about it here. If you go, be sure to send pictures to!


iframe-slider2-simple-350x215Oregon BEST is the best! The nonprofit research center invests in partnerships that transform new ideas into world-changing clean tech companies and was tremendously helpful setting Indow on a path to success, Sam told the Oregon BESTFEST crowd in Portland today.

It was an Oregon BEST grant that paid for a study early on proving the energy efficiency of Indow inserts.

Portland State’s Green Building Research Laboratory studied four Portland area homes that installed Indow inserts. That study initially predicted that Indow inserts would save homeowners 10 percent on their heating bills. But it found it actually saved them almost 20 percent! And here’s why: a person feels warmer standing next to acrylic than a single-pane of glass even if the room temperature is the same in both cases. And that in turn makes that person less likely to turn up the thermostat.

Those results were backed up by a U.S. Department of Energy study released earlier this year that found Indow inserts led to a more than 20 percent reduction in heating, ventilating and air-conditioning use in a Seattle home.

We’re grateful to Oregon BEST for believing in Indow as we seek to make the built environment more energy efficient!



A comfortable family is a happy family!

Summer isn’t quite over yet, but think back to last winter. Was it a multiple-sweater-can’t-drink-enough-hot-tea-my-house-is-freezing kind of season? Then you might be thinking about home weatherization.

Where to start? A home performance contractor can help you assess the energy efficiency of your house and provide strategies for increasing it, but there are also DIY resources for the handier types. Whatever direction you take, keep in mind the four myths below and you’ll be sure to save money and create greater comfort and happiness in the long run.

Myth #1: Replace your windows.

This will cost a small fortune and is unnecessary for home weatherization! Whether you have double-pane or single-pane windows, Indow thermal inserts will instantly block drafts and make your home more energy efficient and comfortable. Don’t just save money, save your existing windows.

Myth #2: First weather strip and caulk doors and windows.

This will help stop drafts a bit but won’t get at the real culprits: big leaks are usually in attics, crawlspaces and basements. Read this great Energy Star DIY Guide to sealing and insulating.

Myth #3: Insulate your attic first.

First air seal your attic, then insulate it. Otherwise, air holes in your attic can lead to moisture and mold in your insulation.

Myth #4: The most energy-efficient homes will have to sacrifice some comfort.

Actually, if you feel comfortable you’re less likely to turn up the thermostat. That’s one reason it’s important to tackle drafty windows in a home weatherization project. A study by Portland State’s Green Building Research Laboratory found that because the interior of an Indow thermal insert is warmer than the inner surface of a pane of glass, a person will feel warmer standing next to an Indow than a single pane of glass – even if the room temperature is the same in both cases.

Resized Alcatraz 2 for WordPressAlcatraz. An iconic part of American history and folklore. Al Capone, George “Machine Gun” Kelly, Robert Stroud, a.k.a.“The Birdman of Alcatraz,” all spent time at the former federal penitentiary in the San Francisco Bay designed with the intention that no criminal could ever escape.

And now Indow will do time there too!

Next week our CEO Sam will photograph the initial installation of Indow window panels in the gun gallery of the New Industries building in preparation for the latest exhibit by Chinese artist and dissident Ai Weiwei.

Ai Weiwei, known for his work on freedom of expression and human rights, was once under house arrest and even now can’t leave China. That was just one of the many challenges of putting together the show. Another: Ai Weiwei wanted the audience to view his work from a gun gallery full of broken windows where guards once trained their weapons on prisoners below as they did laundry and made clothing. 

But that meant opening a part of Alcatraz off-limits to the public. FOR-SITE, the foundation organizing @Large: Ai Weiwei on Alcatraz, had to carry out this powerful vision without putting a single nail or screw hole in this National Historic Landmark. Our amazing San Francisco dealer Kevel Home Performance was essential to the project’s success both for architectural insights as well as Kevel’s expertise on the ground during the laser-measuring process.

FOR-SITE asked us to custom engineer a solution that would shield visitors from Alcatraz’s broken gun gallery windows without leaving a mark. And we did! Working collaboratively with Kevel, Indow developed a removable window mullion that uses a pressure fitting to stay in place. Up to two of these removable window mullions were used to subdivide each window. 

Visitors will view Ai Weiwei’s work through transparent Indow Windows inserts, which will protect them from broken glass (and help them resist the temptation to snap off a piece of Alcatraz as a souvenir!)

IMG_0337Indow Windows’ unique window inserts press into place using our patented Compression Tube without screws or any other damaging changes to the existing structure. Indow’s innovative cleantech product is one reason FOR-SITE managed to put together this exhibit at one of America’s most popular tourist attractions just nine months after receiving State Department approval.

The gun gallery is in the two-story New Industries Building, constructed between 1939-1941, where inmates did laundry for the military and manufactured clothing, shoes and brushes. It replaced the nearby Model Industries Building, which was the site of several attempted escapes.

@Large: Ai Weiwei on Alcatraz runs from September 27 – April 26. Let us know if you go to see it!

Shade Grade Crop 3Summer in New Mexico is hot. But this year Beverly was convinced she had been experiencing a cooler than average summer. When she learned it had actually been hotter than normal, she knew why: she had installed Shade Grade Indow Windows inserts on her home’s 19 windows.

“I used to have to close the blinds and pull the curtains to keep the afternoon sun from baking the bedroom. Now I can have the Indow Windows alone.”

This is our newest grade and one we’re super excited about since it’s perfect for those hot, dusty climates with unrelenting sun. Shade Grade helps block the solar heat gain through Beverly’s windows making her 1930 Mediterranean bungalow more comfortable when the sun is blazing. She hasn’t run her evaporative cooler as much and is looking forward to lower energy bills.

She also appreciates that Shade Grade lessons the harsh white glare she sees when she looks out her windows. Legally blind, she used to have to put on sunglasses to look outside. Now her windows have them thanks to Indow Window’s dealer, Current C Energy Systems in Albuquerque.

“New Mexico sun is extremely strong in the summer,” she said. “It’s so bright I keep the blinds closed. Now I can leave my blinds open more and get more of the outside inside.”


Baby near the double-pane train

Who put baby in the corner of this double-pane?

Double-pane windows promise an insulation value double that of single-pane but don’t always deliver. Pat Bushway bought a 29-year-old house in Hampton, New Hampshire with double-pane windows that blew drafts as if they were old-fashioned single-pane windows.

“They’re just really drafty,” Pat said.

Often people seek out Indow Windows when they have older homes with just a single-pane of glass separating them from the cold weather outside, but we work wonders on newer homes with more modern windows that just aren’t performing as they should be.

Pat called Clearview Sunroom & Window in Dover and bought 24 Indow Windows to make her home more comfortable for this coming winter so she could get away from blow drying plastic sheeting over her view to the outside world. She is looking forward to watching them perform and so are we!

Another double-pane window story that caught our attention could be a cautionary tale about moving too quickly to replace single-pane windows with expensive double-panes. A report by The Snell Group found problems in 10-year-old double-pane windows filled with argon gas made by a reputable company. Just 10 years old! Condensation formed in the center and some even imploded. The reason? The report found that argon escaped from the window but wasn’t easily replaced by air, creating negative pressure in the space between the two panes. That pushed the two panes of glass close together, which led to heat transfer and during the right conditions, condensation in the window’s center.

Remember this: Indow Windows provide real double-pane performance at a fraction of the price and leave beautiful old windows intact.

Brad&LaurenInstall2Today is the longest day of the year when that glorious sun shines on and on. After dinner, you can play capture the flag, ride your bike, walk or talk on the porch for hours. Sleep? Trickier for sure.

To stay healthy, sharp and creative adults need 7-9 hours of sleep every night. If you’re battling the late night and early morning sun with these long summer days, Indow Windows  blackout panels block all light and make a room super dark. (Like I-can’t-see-my-hand-in-front-of-my-face dark.) They’re perfect for shift workers who might as well be experiencing the summer solstice every day since they’re always trying to sleep when the rest of the world is awake! They hush a room too, quieting all early morning sounds be they crows, traffic, garbage trucks or troubadours.

Dark, quiet rooms can help improve a person’s sleep tremendously. But other things can help too. Read more on healthy sleep tips from the National Sleep Foundation.
