These Ingenious Window Inserts Will Slash Your Heating Bill

, Popular Mechanics | 8/11/16

On freezing cold winter days, my wife does this endearing thing where she walks around the house wearing a full-length parka with a big, furry hood. I ask her if she’s going out. “Maybe,” she says. “It’s probably warmer out there.” Then I usually say something about how oil doesn’t grow on trees, and in the old days they used to wrap themselves in animal pelts when it got cold, or at least they would weave sweaters, and we have lots of sweaters, which we didn’t even have to weave.

By this time she has left the room.

Our house was built in 1866 and still has the original windows. The wooden sashes are in beautiful shape, and many of the wavy, handblown glass panes are still intact. Unfortunately, the windows are not airtight anymore (if they ever were), which means the house is not warm, which is why my wife turns up the heat, and then I turn it down, and then she puts on her parka.

I’ve spent a lot of time and a good bit of money searching for ways to make our windows more energy-efficient. I tried the plastic-wrap things you adhere with a hair dryer. I bought some metal tracks that were supposed to make the sashes fit more snugly in their frames, but they arrived dented, were flimsy, and I badly gouged one sash trying to install them.

My advice: Don’t wait until the temperatures start to drop to do something about drafty windows. It takes a while for your custom inserts to be made. First Indow mails you a laser-measuring tool. You take your measurements, enter them on the company’s website, mail the tool back, and then they make your inserts. It’s all fairly simple, and they’ve worked out all the bugs, but there can be slowdowns during the high season. Order a set now, while no one else is. I’ve already ordered mine, so that next winter, no one in my home will feel the need to dress like a dog sledder while watching television.

By the way, when they arrive this summer and you’re trying to keep the hot air outside, I found this too: These things also work in reverse.
