Hi Folks, today let’s talk about storm windows. Wood or aluminum…we seem to either love them, or hate them! But there is a better solution!!! Read more to learn about The Best Wood Storm Window options!

Storm windows are a very important aspect of an old home. Aside from the added charm (did I mention “wavy” glass?) and curb appeal, they protect your historic wood windows from the harsh elements and help save energy. So what happened to them?
Ever wonder why we always see those ugly 1960s aluminum storm windows, and less of the historic wood-style on old homes these days?
Why Traditional Wood Storm Windows Are Mostly Extinct:
-
- Wood storm windows are heavy and require hauling them up and down a tall ladder – NO THANKS!!!
-
- Wood storm and screen windows were completely separate units – DOUBLE THE WORK…DOUBLE THE STORAGE!!!
-
- Way before air conditioning, storms had to we swapped out every summer and winter (glass storms and screens – WHAT A HASSLE!!!
- Lighter, cheaper aluminum storm windows eventually started replacing wood.

Storm (all screen)

Storm (all glass)
THE FIX: The All-Season Wood Storm Window
- Install an all-season storm window: A unique and innovative wooden storm window, where the lower sash is routed out to create an edge, allowing removable panels (glass and screens) to be installed .
- Upper sash – fixed glass/glazed.
- Lower sash -removable from inside of the house (glass and screens).
- Upper/Lower – make BOTH removable, if your goal is to restore/retain double-hung window air flow.
- All-season installation – no more swapping out windows twice per year!!!
- *Note – Make sure the lower rail top edge is routered on an angle so it doesn’t hold water!
Wood Storm Sizing / Construction / Installation
- Cedar or pine ~1 -1/2″ thick ( I prefer cedar for rot resistance)
- Mortise and tenon joint construction. Blind tenon and pin joint may also be acceptable.
- Size and build window frames with the following gaps between the casing:
- measure window opening in 3 places (top, middle, bottom) and cross measure for square (or not).
- 1/4″ gap at bottom (for drainage and ventilation)
- Bevel bottom edge to match slope of window sill.
- 1/8″ gap on all other sides for expansion.
- Router the back side about 1/2″ wide, and to the depth of your removable frames that you select locally (~3/8″ deep).
- *Note – Make sure the lower rail top edge is routered on an angle so it doesn’t hold water!
- Glaze in the fixed sash (usually upper sash only) if just the lower sash is removable.

- Lower sash removable frames (glass and screen)
- Local storm window/screen/door shop (Robertson’s, etc) can build your frames based off the finished storm window dimensions.
- ~$20/per window (1 glass frame/1 screen frame)
- “Wavy” glass option: Use salvaged windows and hand pick them for the “wavy“ glass look. Remove glass from the old sash and have it cut to size when making the frames!!!
- Local storm window/screen/door shop (Robertson’s, etc) can build your frames based off the finished storm window dimensions.

- Finish
- Stained and finished to match our porch ceiling and new porch swing.
- 2 coats of Sikkens CETOL SRD (Dark Oak 009) stain for color.

- 2 topcoats of Sikkens CETOL Window and Door ( Satin Colorless 003).

- UPDATE: After about 4-5 years of exposure to the elements, the Cetol is chipping and peeling on our 2 sunniest sides of the house. As a result, the wood is discoloring as well. I will be trying alternatives to Cetol such as Waterlox Marine Sealer, as it is a sealer that “soaks in” and may retain the wood color better when staining (as the finish wears, wood is still sealed vs topcoat peeling to expose raw wood). You can also apply a “satin” finish on the last coat with Waterlox Marine Satin Finish

Thank you for the article about how you should get windows replaced. My sister wants to get new windows installed. I think she should get that done quickly before the summer ends.
You’re welcome.Thx for the feedback and glad to help!
Great article. I have been designing new storm windows for my 1895 Victorian for the past year, and the complexity of my designs were holding me back. The concepts you lay out here should significantly simplify my tasks. One question I have is about sealing the glass insert against the wood frame. How can I keep water from coming in at the bottom of each pane? Did you use any rubber or poly stripping between the glass and the wood?
Thanks,
Joe
I had the same question as Joe. Have you seen any water infiltration between your frame and insert panels? Great article, thank you for posting it.
Hi Robert, yes, a little bit…but I used the “brush” seals instead of silicone, so the water can somewhat drain and breathe. I also finished the frames with 3 coats of spar varnish for added protection. The biggest issue is on the flat of the frame on the outside. The finish has failed due to standing water. I updated the blog to note that that edge needs to be chamfered to shed rainwater. Hope this helps!
Hi Joe, I used the fely “brush” seals instead of rubber to prevent sealing water against the wood. After 6 years this seems to let the water somewhat filter through. No water issues yet on the the inside channel
Trying to find someone local who can build a new storm window. I have a missing storm for my kitchen window. I still have the screen to use for a template.
What is your location, city, state?
