Ron Badley and the First Window InsertsThe story began with a problem inside Ron Badley’s own home. Ron grew up on a small farm in rural Washington without electricity or running water. Water was pumped by hand, and his high school physics project was a solar water heater. He later built a career working with commercial and residential heating and air-conditioning systems. In the early 1990s, Ron and his family lived in a 1940s brick house in Southwest Reno. Its original single-pane steel crank-out windows were cold and drafty. Ron understood that better heating equipment could not solve the comfort problem if outdoor air continued leaking through the windows. He developed a removable interior panel made from clear vinyl film stretched over a lightweight aluminum frame. A compressible gasket held the panel inside the window opening, reduced air leakage and created an additional insulating pocket of air. The inserts made the rooms more comfortable without replacing the original windows. Friends and neighbors began asking Ron to build panels for their homes, turning a practical household solution into a local business. In February 2002, the Reno Gazette-Journal profiled Ron and the growing product under the headline “Saving Energy With Storm Windows.” Zip Window Warmers
Ron formed Zip Window Warmers in Reno in 2001. The name reflected the product’s practical promise: the panels installed quickly and helped make cold, drafty windows more comfortable. Early growth came through referrals, local advertising and home shows. Demonstration displays let visitors feel the difference between an untreated window and a window fitted with an insulating panel. Reno’s historic Lake Mansion also installed the panels, showing how interior inserts could improve comfort while preserving important original windows. Eric Swanson Buys InEric Swanson encountered the product after buying a 1923 Reno bungalow with 23 old windows. Ron had serviced the home’s heating system for years and recommended the inserts as a practical answer for the window drafts. Eric installed the panels in his own house and experienced the difference firsthand. Eric brought a complementary background to the business. He earned a BA in History from Colorado State University and worked with the Minnesota State Historic Preservation Office on its standing-structure database. He later served as the first Interim Webmaster for the Minnesota Historical Society and worked in web and database development for businesses, museums and nonprofit organizations. His historic-preservation experience helped him understand why many owners want to improve older windows rather than remove them. His web-development experience helped turn a local product into one customers could learn about, measure, price and order online nationwide. Eric bought half the company in 2004. Window Inserts LLC and WindowInserts.comRon and Eric formed Window Inserts LLC in 2005, introduced the EnergySavr Window Inserts name and launched WindowInserts.com . The domain was chosen because “window inserts” plainly described the product: removable insulating panels inserted inside existing windows. Archived website records show that WindowInserts.com was active years before the best-known companies that later adopted “window inserts” as a product category. EnergySavr helped name and establish the category when the website launched in 2005. 
Building a Factory-Direct Online ModelEnergySavr Window Inserts briefly expanded production and sales to White Bear Lake, Minnesota, in 2005. Minnesota’s cold winters and large supply of older homes created strong demand, and the company demonstrated the inserts at home shows throughout the Minneapolis–Saint Paul area. The company was featured in the St. Paul Pioneer Press in December 2005 and Minnesota Technology Magazine in Spring 2006. 
The expansion helped Ron and Eric develop a more efficient factory-direct model for selling custom window inserts nationwide. The goal was to make a custom-fit solution easier and more affordable for more people to buy. Customers could watch measuring videos, read the instructions, measure their own windows, enter the dimensions online and see pricing immediately. The inserts could then be custom-built in Reno and shipped directly to the customer. Production was consolidated in Reno in 2006, and online ordering became the company’s primary model. That approach remains one of the main reasons EnergySavr can offer affordable custom sizing without adding the cost of routine in-home sales visits. Featured on NBC’s TODAYEnergySavr Window Inserts appeared on NBC’s TODAY in 2009 during an energy-saving segment with Lester Holt. The national exposure introduced the inserts to viewers across the country and created a major increase in demand. The product returned to TODAY in December 2025 during a winterizing segment with George Oliphant, who said he was “definitely a big fan of these window inserts.” The two appearances were separated by sixteen years of continued manufacturing, online sales and nationwide shipping from the Reno shop. Giving Back
After Hurricane Harvey in 2017, we donated $7,088 to the American Red Cross Northern Nevada Chapter. The donation supported the chapter’s disaster-preparedness and Sound the Alarm efforts. What We Make TodayToday, we remain focused on one core product: affordable custom-fit interior window inserts that stop drafts, add insulation and improve comfort without replacing existing windows. Our inserts use vinyl film, not rigid acrylic — for stopping drafts at a fraction of the cost of premium acrylic brands. Each insert is built from strong, clear vinyl film stretched over a lightweight aluminum frame. A replaceable foam gasket helps the panel seal inside the existing window opening, while the space between the insert and the glass adds another insulating layer. The panels press into place from indoors, making them easy to install, remove and reuse. Their lightweight construction helps keep custom sizing affordable and practical for everyday customers. Our window inserts can help improve drafty windows in a home, rental property, business, church, historic building, screened porch or other space. Our factory-direct system gives customers the information they need before ordering. They can watch the videos, read detailed instructions, measure at their own pace, enter sizes online and see pricing immediately. Our window inserts provide a practical and much more affordable way to reduce drafts, improve comfort and help save energy without a major replacement-window project.
