With the 3M outdoor patio door insulator kit, you can lower your heating bills during the winter and make your home more energy-efficient. Part of 3M's line of energy-saving products, this kit includes insulation film and a roll of double-sided mounting tape to create an airtight seal. Stretching the film removes wrinkles for a transparent view. This kit enables you to insulate one patio door measuring 6 feet 8 inches by 9 feet.
Keep the Heat In and the Cold Out
Made by 3M, this outdoor patio door insulator kit contains insulation film along with Scotch film tape to keep cold drafts out and warm air in. As a result, you can reduce your heating costs during the winter. The film shrinks tight around your door frame for a transparent, wrinkle-free fit and is made to reduce condensation and prevent frost build-up.
Double-Sided Mounting Tape for a Secure Seal
Included with this kit is a 1/2-inch-by-13-4/5-yard roll of 3M film mounting tape to keep your insulation in place all season long. This double-sided tape seals off cracks and crevices, creates an airtight seal, and establishes a strong bond between the surface, the tape, and the insulation film, as recommended in ENERGY STAR's "Seal and Insulate" guidelines. Featuring a convenient, ready-to-peel liner, the tape adheres easily to a variety of surfaces and stays intact upon removal.
Simple, Fast Installation
Installing the door insulation is easy. You simply unfold the film and cut it to the width of the door frame, allowing an extra inch on all sides. Next, you firmly apply the mounting tape around the frame and remove the paper liner. Then you apply the film to the tape, starting at the top of the door, and reposition and stretch the film to remove wrinkles. Finally, you press the film firmly to the tape and trim any excess film.
Made in the United States, and designed for outdoor use only, this insulator kit can be used with aluminum, painted wood, or vinyl-clad surfaces, but it should not be applied to masonry or to roughly sawn or unpainted wood. The film and tape should be removed from the door at the end of the season. The film measures 7 square yards, or 7 feet by 9.3 feet by 0.75 thousandths of an inch (H x W x D), and weighs 0.24 pounds.
What's in the Box

Will not stay on your door if it’s exposed to weather and wind. Easy to put on but blew off.

Got this to reduce condensation on windows in the winter. Works so far for 68 degrees F and 60-70% humidity inside and 30's outside. Compared to the Duck Brands equivalent stuff, it's more transparent/clear and has a more rigid rather than stretchy feel to it. Although the instructions don't say so, you CAN shrink it to get rid of wrinkles with a hair dryer. Currently using this indoors rather than outdoors as it's marketed - I figure that's fine rather than doing the reverse.

Here is what I suggest when installing this.Have scissors, painters tape, rubbing alcohol, paper towels.1) Fully clean the surface where you going to stick the double-sided tape. Then suggest you use a paper towel and rubbing alcohol to clean those surface once more. Let it dry completely, then apply the double stick tape to that surface. DO NOT peel off the paper side yet or you will have a total mess.2) Unfold that plastic folded sheet completely and do a dry fit to see how much excess you will have on each side. I know the instruction says cut it to size, but I cut it at the very end.3) Suggest you double line if possible of the double stick tape for the top, only if you have extra once you have applied the tape all around first.4) I suggest use a piece of blue painters tape to temporarily hold the two top corners. When you expose 1st the top double stick tape to stick the sheet plastic first.5) Then do the left and right side. Pull away the paper tape backing of the double stick tape slowly as you go. This way you don't have the plastic sticking by itself and making a mess.6) last is the bottom to do, same pull off the double stick paper backing slowly as you go along.7) Once all sides are done just go back with your scissor and have it glide cut the excess easily.The double stick paper backing is a pain in the neck to remove. Just have to be patient.It doesn't go skin tight like the indoor type but it does work to insulate and stop the cold .Overall looks okay and seems to work. Will update if it fails.

With this changing environment I have been unable to let my screens be uncovered. I have a cat door that doesn't fit in the custom sliding door and it has to be used with the screen door. Way too cold in the winter and this summer was too hot. So I put this over the screen door and it kept the temperature way better in both seasons.

Según yo, sí funcionó. Lo coloqué en una ventana durante el invierno y podría jurar que sentí menos frío.Lo que sí, es muy complicado de instalar si necesitas cortar la pieza enorme que viene

I've used this weatherproofing kit on our outer windows for at least the last 20-25 years. Our house was built in 1884 and breathes through the walls and windows each winter. This winterizing kit for windows makes a huge difference in our natural gas bill and the comfort of our house. It's fairly easy to apply once you've read the directions. I buy an extra roll of tape along with the kit to make double rows of tape so that there is enough to hold it on tightly. I learned that lesson the first year I used it. Also, you really do need to clean the surface well before applying it to make sure it stays on during Noreasters! Once you've applied it, the blow dryer should get rid of any wrinkles. I use prepackaged alcohol prep wipes to get all the dirt and oils off the surface before applying the tape. It doesn't cost much but I think of it as insurance to make sure it lasts through the winter. You should clean the outer glass panes before applying so you don't have to look through dirty windows all winter. I absolutely love this product and wouldn't go thru the winter without it.Linneaann

I put this up last night and the tape already seems better then other brands I’ve used. It is very clear and I can’t tell it’s there when looking out the window. I did clean the boards so the adhesion would be as best as possible. They have a note in there about the plastic sheeting being stuck together and needing to use 2 pieces of tape to pull it apart. This is very true, you can’t even tell it’s folded it’s so seamless, so DO give that a try to open it fully.I start by adding the tape around the door first leaving the backing on, then unfold the plastic sheet and attach it to one tape side at a time. Pulling the backing off and sticking the plastic in increments as I go. This was very easy to pull of the tape and adjust when needed but still felt like it would stay sticking for a while.

This was the worst item I have ever purchased online. The box had been opened there was no tape in the box, and it certainly was not the item as described. It was a scrumpled up sheet of plastic that was even cut to size. Ib think someone just put a random piece of plastic in the box. Absolutely disgraceful.

I didn’t buy this for a door but rather double windows that are larger than the window package 3M has. This product worked perfectly for the winter months! I didn’t expect it to stay flat as it’s normal for the plastic to become one big bubble when the barometric pressure in the atmosphere rises, so I left some slack in it when applying it. I also did two lines all around the window of the adhesive tape that comes with this item. Also - I attached it to the wall outside of the window, not the window pane as I felt this was better coverage and less likely to leak. One thing that I think most every one can agree on - I wish the adhesive was stickier! Had it not been for the two rows of the tape then it definitely would have come undone.

One out of 2 packages was completely unusable because the plastic was fused together and although we've used these products for years without any problems, these ones keep coming off. The sticky tape condition was compromised. Have had to order more of the window kits (and pay significant shipping) but hope they arrive in better shape or next time we'll try a different product or order from elsewhere.
