Craig and Shari loved their Portland home with its awesome neighbors and close proximity to schools and restaurants. When their growing family required larger quarters, they decided to add a story to their home rather than move. Their budget limited the family to vinyl windows if they wanted thermal replacement windows throughout the home. They started looking for a window replacement alternative that would keep the cold out.

They wanted to stop the energy loss and high heating bills, but the look of vinyl would not fit with the charm of their 1922 home. Windows account for nearly one third of energy loss in a home, so they needed to find a thermal window replacement alternative that would allow them to preserve their windows while still reducing their energy bills by up to 20%. Their solution: high-end, double-pane wood windows for the second floor addition and Indow window inserts throughout the first floor.

Indow inserts are AERC certified. AERC, the Attachments Energy Rating Council, is an unaffiliated organization that rates window attachment products on energy efficiency by measuring various factors such as Air Leakage (AL) and U-Factor.

On air leakage, Indow scored in the top two out of 33 storm windows tested, 11 of which were interior storm windows. U-Factor is an indicator of heat transfer and tells you how well a window product insulates. Indow inserts have a U-Factor of .3, making them a top performer on insulation among all available storm windows. Installing Indow inserts in original windows, like Craig and Shari’s, allow them to perform at the level of thermal pane windows.

Testimonial

“The old double-hung windows make the space feel much more relaxed and comfortable than if I’d gotten window replacements, but my tiny electric space heater would have been going 24/7. Using Indow inserts, the space heats up fast and it stays warm for hours, even after I switch off the space heater. It’s actually more comfortable to sit on the sofa next to an Indow insert than it is to sit next to the brand new double panes. We’ve been pleasantly surprised by the Indow inserts!”

The condensation that used to steam up the inside of their single-panes has disappeared and the Strongs noticed another benefit, the first floor is now very quiet. They love how walker-friendly the community is, but it’s nice not to hear every conversation as their neighbors stroll by.

When Craig converted the detached garage in their backyard into a studio, he fitted two beautiful recycled single-pane windows and fitted them with Indow inserts. Stories like the Strongs’ warm our hearts. Tell us yours!
