INSTALL GUIDE
INSTALL GUIDE
The Steps:
- Clean: Wipe your window frame with rubbing alcohol to ensure a strong adhesive bond.
- Apply Frame: Remove adhesive backing and stick the framing strips along the perimeter of the window.
Note: Each strip is 24" long. If your window height or width is longer than that, simply place the strips side-by-side (end-to-end) to cover the full distance. Cut the last strip to fit if needed. - Cut & Place: Cut the vinyl sheet slightly larger than the window. Press the vinyl against the base frame.
- Lock: Snap the spline strips into the base frame to lock the vinyl tight.
- Trim: Use a utility knife or scissors to trim the excess vinyl for a clean, professional look.

Product FAQs
Are these storm window inserts reusable?
Yes — that's the whole point. The vinyl sheet and framing strips are built to be removed each spring and reinstalled each fall. Unlike cheap plastic window kits that go in the trash after one season, RuxEco inserts are UV-resistant, waterproof, and designed to hold up for years of use.
What's the difference between this and a regular window insulation kit?
Standard shrink-and-seal kits use flimsy plastic film and double-sided tape — they're single-use, often pull paint when removed, and need to be repurchased every year. RuxEco's interior storm window inserts use heavy-duty 6-mil vinyl held in place by reusable snap-in framing strips, so you get a more durable seal, better clarity, and a kit that lasts for years.
Can these plastic window inserts be used in summer too?
Yes. Unlike shrink kits that trap heat and haze up, RuxEco's crystal-clear vinyl inserts can stay up year-round or be easily removed when you want to open windows. Many customers use them as a window insulation kit for summer to reduce heat gain and keep AC costs down.
What size interior storm window insert do I need?
Measure your window frame — width and height. Our kits come in multiple sizes, and the vinyl sheet can be trimmed to fit. If your window falls between sizes, always go larger; the vinyl cuts cleanly with scissors or a utility knife. So for instance if your window is 32 W and 52 L...the 36x60 size kit will cover your window.
How do I install interior storm window inserts?
Clean the window frame with rubbing alcohol, press the self-adhesive framing strips around the perimeter, cut the vinyl sheet slightly larger than the opening, press it into the base frame, then snap the spline strips in to lock it tight. Trim any excess. Most windows take under 15 minutes.
I had used a similar product 40+ years ago...one tends to loose site when you move about, life happens etc. After living in my home for 19+ years, tends to get a little chillier each year. I started looking for the plastic insulation for windows and came across this site!! First I have resealed ALL windows with the weather stripping, I caulked and re-caulked the entire upstairs, and ordered two three packs of (48"x72"). Once they came in I immediately cleaned the windows, and each blind slat, then installed them on my two windows in my bedroom. Yes, I fully intended on covering the window with the blinds close. I have a lot of allergies, so opening windows is a no go.
I can honestly say, I am pretty cozy and stay warm in the evenings, even during low temperatures. Last year I tried keeping my thermostat down at 98 degrees in winter, but kept putting it one or two degrees higher to take the chill out of the air. This year, I have kept the thermostat at 68 degrees, sometimes I forget I have it set for 67 degrees from 430am - 5pm during the weekdays. Before installing, going to bed meant, socks, slippers, bathrobe and several blankets - sometimes still getting a chill, after installation, can sleep normally and even got warm enough to move some of the blanket off, no chills.
This weekend, I will be installing the inserts in the two other upstairs bedrooms, then the living room. Then will follow up with a couple of the basement windows.
Thank you!!! works GREAT, absolutely NO cold coming from the window area at all!! And on the PLUS Side, the noise that was really bothering me, sensitive ears, I may slightly hear a muffled sound, but can work and concentrate on the computer without issues.
Thank You!!!

Im really happy already with this product. I was looking for something for winters that is more durable. The ones with double-sided tape would always end up falling off. The fact the plastic can be removed and reused each year makes it worth the premium you pay vs the cheaper stuff.
I have larger windows but was still able to get the 48" width and run trim on the middle, and it still managed to snap in place with two layers.
I can't speak highly enough about their customer service. I had a small issue with the wrong size film being sent and they resolved it no fuss. I also had another order that I later asked to cancel and it was a breeze.
I have been looking for something to seal the windows in Winter besides using the standard shrink wrapping kits. My windows have a ledge, not a flat edge all away around the window. I was able to jerry-rig a way, with the extra pieces, so I could use the kits. I have a heavy duty tin snips that allows me to cut the pieces to the right size as well. I will be ordering more kits for my other windows that can use this.
I used 2 kits and taped the seam using weather using tape. It’s doing a great job of keeping the drafts out and letting light in. Super sturdy. Glad I found these.
I bought 1 window kit to try out. The quality of the materials looks great. I haven’t installed it yet but am pretty sure I’ll be buying more to cover all my windows. Being able to reuse is a big plus.
