A Storm Window That Works from the Inside, Out

Storm windows are a great way to increase energy efficiency and seal out drafts during inclement weather, but we were on the hunt for a more attractive solution. Enter Indow; they’re attractive, reduce energy consumption and work from the inside out!

This post is in partnership with Indow.

Insulating Without Interfering

We’re finally at a point in our 2+ year Tree House renovation where we can begin focusing on small details that make a big difference! During our recent exterior renovation, we removed all of the home’s faded aluminum exterior storm windows so the window trim could be repainted. Once the painting was complete, we were far from excited to reinstall them over the freshly painted trim, but we didn’t think we had a choice – ‘think’ being the operative word. Here, let’s have a look at the (way) before and after comparison. I’m going to focus on the mudroom window, the taller one next to the door, below:

Painting the trim bright white allowed the shape of the historic window to shine through in a way that we wanted to showcase. Yeah! Inside, the black window frames the view of the wooded lot next door (a view that we love), and we hadn’t realized how much of it the old storm window was blocking. Boo!

It was around this same time that we discovered Indow window inserts! Indow is an American company based out of Portland, Oregon, creating compression-fit window frame inserts that are incredibly accurate in size, and – perhaps my favorite part – virtually invisible. These inserts reduce noise and drafts while reducing energy consumption, and they’re installed without the use of any hardware or tools! In other words, Indow inserts are great for vintage homes (like our 1930s Tree House!), as they help to preserve historic character while adding modern efficiency. Check out the video below to see how simple our measuring and installation process was:

The Whole Kit and Caboodle

Indow assigned us a knowledgeable representative in the chance that we’d need guidance along the way, and they also sent us their proprietary measuring kit. The kit included a laser measuring device, color samples and a few other gadgets to ensure that the end result fit perfectly.

Measuring + Ordering

We started the process by swiping this handy gauge along the outermost lip of the window molding. This step ensured that we had enough surface area to firmly hold the insert’s compression tubing; more on that in a minute. We were happy to see that our trim allowed for more than enough space for the insert.

After confirming that our window was a good candidate, we measured the width, height and diagonals of the windows with the included laser, and we input those numbers into a form on the Indow website. This couldn’t have been more easy, since Indow includes thorough, easy-to-follow instructions! Our window was almost perfectly square, but if it had been a bit askew, Indow can account for that – no problem!

Once measuring was complete, the final step was to decide between the color samples. Originally, we thought we would want the black insert to match our black window frame, but after noticing that the black insert would still leave a sliver of the white window jamb in view, we ended up preferring the white for a cleaner look. With our final decision made, we placed the order and waited for the insert to arrive!

Installation + Cleaning

Fast forward a handful of weeks, and our Indow insert was waiting for us at Tree House! Installing the insert required absolutely no tools and no hardware. The frame of the insert is edged with silicone compression tubing, creating an impressively snug fit. Starting at the bottom, I carefully pushed the insert into place and worked my way up. Once in place, the insert created an airtight seal that you can almost feel. Color us impressed.

Included with our new insert was a cleaning solution and soft cloth. Once everything was in place, Kim used the cloth and spray to wipe off any smudges and fingerprints.

Disappearing Act

Done! With the Indow insert in place, it virtually disappears into the framework of the window itself. From the kitchen, it’s almost undetectable!

Unobscured Views

Our Indow window insert met every single one of our needs. Increased efficiency for our historic window? Check! Unobstructed view of the woods? Check! Easy installation with no damage to existing trim? Check!

The slim profile allows almost the entire black window to show through. It blocks absolutely none of the natural light that comes through this window, and it even allows for an unobstructed view of the original brass hardware!

Without Indow vs. With Indow

Because our historic window’s operation was limited due to aging internals, we’ll likely leave the insert in place year-round. Our window also lacks a proper screen, so if we need additional ventilation, we’ll utilize the half-screen storm door right next to it. However, do you notice that small pull ring in the lower left corner? It’s the only very small, barely visible hardware on the insert, which aides in removal should you like to do so!

From outside the house, the insert is completely invisible, which allows our window to shine through in all its vintage glory!

The Indow window insert has allowed us to add efficiency while maintaining as much of the historical character of our little home as possible. We were so impressed by the easy measuring and ordering process, and the quality of the unit is outstanding! This project was wrapped up just in time for the dipping temperatures, and we’re looking forward to cozy weekends without pesky window drafts spoiling the vibe.
