Duck 1163221 Indoor Shrink Film Insulation Kit Insultation, Clear, 10 Windows

Product Information

DIY fans, rejoice! Window insulation is not supposed to be a forever fix. It’s more of a tactic to help cut the cost of your energy bill when you can’t afford to replace or upgrade your windows. For the most part, the only tools you should need include a measuring tape, scissors, and a hairdryer.

After the film is secure, shrink it with a hairdryer. The result is a surface so transparent you’ll have a clear view of falling snowflakes. As long as you’re careful while removing the tape, you can store the kit to use again next year. Magnetic insulation kits require DIYers to install magnetic strips around the window, then cut the film to match. They can be more challenging to install than plastic film kits, and the magnets often create a less-than-airtight seal. Several window insulation product types are on the market: plastic film, magnetic barriers, and reflective foil insulation. The best window insulation kits are effective, affordable, and easy to install. Most kits are installed by placing double-sided tape around the perimeter of the window jamb. Then, window film is applied to the tape. At the bottom of the window, the film is attached to a piece of tape on the sill, making a seal. Finally, the film is heated with a handheld hair dryer to create a transparent airtight seal that’s free from wrinkles. FAQsIf you prefer to install a film on the exterior of your home, the best window insulator kit is the 3M Outdoor Window Insulator Kit. It was specially developed to withstand the elements, though it will most likely only last one year and shouldn’t be reused. You'll notice some differences between shrink window insulation kits when it comes to their application process. "There are two basic types of shrink window kits: one with a pre-taped top [that] rolls out and the other with flat folded film which requires all four sides of the window to be taped before placing the film against it," Shaver says. "Both work equally well, and choosing one or the other comes down to personal preference." Most window insulation kits work the same way: A sheet of heat-shrink plastic or other insulating material is attached to the window panes with double-sided tape or magnetic strips to add a layer of insulation. The best window insulation kits are easy to install and provide an effective barrier to drafts. Windows that have been treated with insulation cannot usually be opened, meaning these kits are a seasonal solution to drafty windows.

In general, Shaver says that installing insulation on the inside of a window is going to be more effective. He notes, “This placement creates a dead air space helping to reduce heat loss and improve energy efficiency.” The kit includes one durable 62 x 210 inches and 84-foot roll of mounting tape that is double-sided to make attaching it easy. Each kit comes with enough material to cover five 3 x 5 windows, so your energy bill is sure to go down.It's important to consider the sizes and number of windows you want to cover, research different materials, and settle on a price you’re willing to pay before you go shopping. Made with puncture-resistant shrink film, this 126-inch-long by 62-inch-wide indoor option is perfect for homes with children, pets, and other high traffic and is easy to install and remove cleanly, making it suitable for first timers. For added reliability, this option can be used on painted wood, aluminum, vinyl, and finishes/varnished wood, but it can’t be used on plaster, drywall, or unfinished wood. Installation is easy but may require a ladder and a partner. Once the insulation is secured and heat is applied with a hairdryer the film will shrink to be crystal clear, tight, and wrinkle-free.

Despite fitting larger windows, the kit is still available at an affordable price. “It’s a budget buy, but it’s effective,” Domniguez says.

Installation & Instruction

With the exception of a ladder and an extension cord to reach it, this insulator kit is installed the same way–and just as easily–as an indoor kit. Simply measure, cut, tape, shrink, and trim. We were pleased to learn that it pulls just as tight and clear as the indoor options. Foam tape window insulation works by creating an airtight seal around the edges of windows,” Shaver says. “The foam tape, which has adhesive on one side, is applied to the window frame and if necessary to the top and bottom of the two sashes. When the window is closed, it compresses, producing a seal that acts as a barrier against drafts and heat loss.” Keep in mind that foam tape generally isn’t designed to last multiple seasons, but it can be an excellent option if you’d rather not have plastic film covering your windows. Installing the tape is easy, as you apply it by simply pressing it onto your windows. Applying the tape will also keep out pollution and dust, which keeps the inside of your home a little cleaner as well as a little warmer. The tape is designed to come off without leaving residue and without damaging wood trim, but you may want to test a small spot just to be on the safe side. It’s also resistant to punctures, making it a durable choice. According to Dominguez, it’s easy to install a window insulation kit, but he advises to not go it alone. “You’re going to want someone to help you install your kit,” he says. “Installation is easy, but it’s not a one-person job. You’ll appreciate having help from a friend the first time.” The Frost King Extra Large Window Insulation Kit is the best window insulation kit if you’re needing to insulate two large picture windows or if you have multiple small windows. It comes with two 62 x 210-inch plastic sheets with 168 feet of double-sided mounting tape, which is enough to cover two picture windows or 10 separate windows without fear of running out.

If you want to insulate your garage doors or windows all year long, the best window insulation kit is the Reach Barrier 3009 Garage Door Insulation Kit. It keeps the temperature moderate in your garage, so you can comfortably utilize the extra space for a home gym or hangout. The kit also has versatile instructions that make it easy to install–even for those who don’t consider themselves super handy around the house. Follow a few steps to cut it to your desired size and secure the right placement. Use a hairdryer to smooth out any wrinkles. Because heat travels from hot to cold areas, the heat generated by a home heating system will leak out to the colder environment,” Benson says. “Window insulation kits function by creating an air barrier between the interior living space and the window. When installed properly, window insulation kits are completely see-through.” Window insulation kits create an effective barrier that prevents cold outside air from getting into a home. Heat-shrink film applied to the window pane with double-sided tape creates an air gap that works like a thermal window. Q. What is the difference between window insulation kits and insulated curtains?This article was written by Belle DuChene, an award-winning digital content producer and stylist who is often seen in Better Homes & Gardens home and garden videos, and Brittany VanDerBill, a contributing writer with over six years of experience.

Window insulation kits vary from each manufacturer, so be sure to read all of the instructions and find the one that suits your needs,” Benson says. The directions for whether you are buying the best window insulation kit indoors or out will be included in the box. While you could typically use the film interchangeably, it's the tape that can make the difference. In a pinch, you could get away with using a plastic film made for the outdoors inside your home, but only if you buy tape made for use indoors. Outdoor tapes may be too strong and could damage your surfaces during removal.
