We were able to attach these easily beside our window AC, but our friends found the process to be slightly challenging. So, if you have a standard-sized panel area, then you will not face any difficulty in attaching them. But if the sizes are different, then you will have to cut them accordingly to fit well. Moreover, these panels are easy to install and come with adhesive on the sides.

Features to consider while choosing a window insulation kit

Many users prefer the lightly tinted models, which most of the models included in our top are, because you can barely notice they are on the windows. Silver tinted insulation kits are often working great for summer as they bounce back the sunlight so it doesn’t get into your room. Window insulation kits create an effective barrier that prevents cold outside air from getting into your home. Heat-shrink film applied to the window pane with double-sided tape creates an air gap that works like a thermal window. From 3M, this kit comes with enough film to cover up two 3-foot by 5-foot windows. At .75 millimeters thick (.05 thicker than average), 3M’s film is relatively thick for enhanced insulation.

First of all, this comes with a loop-hook tape, which is reusable and very convenient to use. It makes the installation process a lot simpler, and you can use it as an alternative to double-sided tape. Some customers have complained that they have not received the tape along with the covers. So, we will recommend that you check the product immediately after receiving it, and in case the adhesive is missing, call up customer care and place a complaint. They will help with replacements, and you should not face any further problems.

Outdoor tapes may be too strong and could damage your surfaces during removal. Insulated curtains do a good job of keeping the cold temperatures at bay, but they don’t create air-tight seals to hold back drafts like window insulation kits do.
