7 best window insulation

Product description

Available in a variety of indoor and outdoor window sizes. 3M Window Insulator Kits keep cold drafts out and warm air in through heat shrink window film and Scotch Window Film Mounting Tape. 3M window kits have the clearest film and stay up all season long with Scotch tape technology. The Scotch double sided tape holds firmly between films and surfaces.

With the 3M indoor window 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 window 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 version of the 3M indoor window insulator kit enables you to insulate five 3-foot-by-5-foot windows.

Keep the Heat In and the Cold Out

Made by 3M, this indoor window insulator kit contains window insulation film along with Scotch Window 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 window 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-27-7/10-yard roll of 3M window 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 window insulation is easy. You simply unfold the film and cut it to the width of the window, allowing an extra inch on all sides. Next, you firmly apply the mounting tape around the window frame and remove the paper liner. Then you apply the film to the tape, starting at the top of the window, and reposition and stretch the film to remove wrinkles. Finally, you use a blow dryer to remove any remaining wrinkles, then trim any excess film.

Made in the United States, and designed for indoor use only, this insulator kit can be used with aluminum, vinyl-clad, or painted or varnished wood molding, but it should not be applied to veneer paneling or Lauan mahogany molding. The film and tape should be removed from the window at the end of the season. The film measures 10 square yards, or 5.16 feet by 17.5 feet by 0.75 thousandths of an inch (H x W x D), and weighs 0.33 pounds.

User questions & answers

Question:	I am from the South, so my big question is, does it insulates from heat so well as it does from cold
Answer:	Short answer: It does not insulate well from temperature exchange through your window, but it does prevent air exchange, so it can dramatically reduce your heating/cooling bill if you are constantly having to condition fresh air from outside.Long answer: I have used this in a warehouse office where we kept it up year-round (because the landlord was too cheap to replace 50+ year old windows). Just keep in mind; First, with less air exchange, make sure that your HVAC has a good filter system, and that you replace it regularly to prevent buildup of allergens/mold in the home. Second, if you live in a particularly humid area then this can result in water (and mold) buildup between the plastic and window during warm weather, which is bad (using the exterior version of this product may work better). Third, these are great to save a few $$ and keep the house more comfortable during extreme weather for a few months, but they are not a good long-term solution. The tape gives out, the plastic can yellow or haze over time, you lose the use of the window, it is easy to disturb and ruin... generally not a good long-term game plan. If you need a more permanent solution then consider using clear caulking to seal the seams/cracks in your window (assuming it is not against safety/fire code, remember you typically need 2 exit points and many rooms only have 1 door and 1 window), or else consider replacing the window.
Question:	How does this hold up compared to frost king
Answer:	This holds up much better then frost king... I have never had frost king last a whole season on my windows but the 3M lasts no matter how long the cold season has lasted. I will never go back to using Frost King again.
Question:	Has anyone had success applying this to a window without trim? Our 50s track house just has drywall-cased windows
Answer:	I want an answer to this too! I also have the drywall-cased windows from the 50s. Thanks!!
Question:	Will this work for insulating from the heat of a hot climate too
Answer:	I would assume so, though we live in Maine near the coast where it can be in the teens and 20s sometimesduring the weather; I assume it would work since 3M is an excellent product - the hardware versionsdon't seem to work as well. You'll need the 3M tape for this as well.

User questions & answers

Question:	Does the tape take the varnish off of the frame when removed
Answer:	I would have to say yes. If you can actually get tape to stick to varnish in the first place. If it sticks, it will take some with it when removed
Question:	What are the exact measurements of this product? I’m reading here from the manufacturer that it’s 62” x126” when the box in the photo says 84”x
Answer:	Thank you for your question! There are 2 window kits listed. One is a patio door kit which is 84" x 120", the other is a 3pk window kit that is 62" x 126". Before purchasing, make sure to select the window kit size you prefer.
Question:	Okay, how do you get the last fold apart? I measured 60" wide. I think there must be another fold to make it 120" but I can't find it
Answer:	First, check the package to make sure you have the 7'x10' version since they also offer a 62" wide product that uses very similar style packaging. Also, note that it is 120" LONG and 74" wide, so static cling isn't an option here. Good luck!
Question:	Will the plastic keep toxic gases from seeping into the house through cheap, single-pane windows
Answer:	Thank you for your question! The window film prevents and blocks drafts; however, we cannot guarantee it will block toxic fumes.

User questions & answers

Question:	Can this be removed and re-used another winter? Sorry if this is answered but didn't get through all 154 reviews. Is it unsightly? Thanks
Answer:	Yes, it can be re-used, even if you use a hair dryer to shrink it. I remove it carefully, fold each piece up, and label it with a sticky note telling which room/window you removed it from. This makes it MUCH easier the next year to reappy. You will need to purchase more double-sided tape to reapply the following year, however, I've found that if you search around on amazon, it is sometimes much cheaper to buy a full window kit, rather than the individual, small 24' rolls of replacement tape.
Question:	Is this just one huge roll of shrink film, or is it 10 separate pieces
Answer:	It is two semi-huge films, 62 inches by 210 inches each
Question:	Will this insulate me from the alt right and still allow me to see out
Answer:	With the alt right who wants to still see out?
Question:	Does this work for Mac too or just Windows
Answer:	It will work on all brands of windows, Anderson, Hullco, Window World, Jellco etc. All types wood, vinyl, aluminum. It is a good product and will help will heating costs.

Answer:	Yes, if you follow the instructions that comes with it. Everything is included and very well thought of.
