Adding a Window Sash to Existing Windows


Hi there friend! 

Today I’m excited to share how much a simple small change like adding a window sash to existing windows can make! The previous owner had replaced all the big windows her at the farmhouse except one. While I’m grateful to have new efficient windows this wasn’t the style that I would have chosen. And since he didn’t replace one of them that’s in the kitchen I was able to see the style of the original ones, which gave me all the inspiration I needed!

Architectural Style 

Even though I would not call us restorationists by any means I do always keep the original architectural style of the farmhouse close to my heart when making any and all design choices. The window that was left original has a single sash divider so I sought out a company that makes them in a style that is VERY close to the original one. I’m happy to report I found exactly what I was looking for and couldn’t be happier with the results!

New Windows 

Above are what the windows looked like BEFORE the sashes were installed. Very basic, not a lot of interest, and they don’t really scream farmhouse as loud as I’d like 😉 And that’s when FixHome stepped in! 

FixHome is a window and door focused company and they have tons of affordable options. I chose their S-Vinyl Single Window Sash Divider because it was the closest match to the original but would still look great with our new windows.

Attaching the Interlocking Strips

On the back of the sash dividers there are notches or grooves cut out of each end. This is where you place one side of what I can only describe as a command strip on steroids lol! The adhesive is STRONG y’all! You put one sticky side down in the groove and the other interlocks with it. This way the other sticky side will be on the glass. Pictured below is the roll they send you. You’ll cut 2 strips for each end. I rounded the corners of mine for a better fit. 

**My biggest tip from this process is to interlock the 2 strips only a little towards the center of the sash then peel the paper off. I’ll explain why below.

Attaching the Sash Dividers

Before you can attach the sash dividers you need to find the center of your windows. After figuring out the center points of the top and bottoms of the windows I cut 2 pieces of wood – one for the top and one for the bottom. This way all I had to do to know the dividers were centered was to place that piece of wood against the outside of the window frame and set the sash against it. It made this process way easier than having to find the center point by measure each windows top and bottom. 

I would cautiously hold the sash so that the adhesive didn’t touch the window until I knew it was in place. Once it was I would push the bottom of the sash against the window first and then the top. I learned that if the 2 adhesive strips were completely interlocked they wouldn’t stick to the window. The grooves make it so that they lay flush against the glass but if you wait to interlock them all the way then they easily stick and when you push on them you can here them snap and connect.

And what a difference those sashes make! Honestly, it was a bit shocking the first couple of times I walked back into the living room! Crazy how a single strip on a window could alter the way the whole room feels, but that’s why I think architectural details are SO important! It’s the character I love and crave from old houses! And because of that, I always want to showcase the architectural features of the farmhouse first and strive so that our decor highlights them! I can’t wait to add these sash dividers to all the big windows in the farmhouse!
