With the onset of winter, it can be really difficult to keep your homes warm without amping up the energy bill. But this window insulation kit comes packaged with a comprehensive instruction guide, making it easy to install and efficiently insulate your house in no time.
The crystal clear film included in this kit readily lets the sunlight and heat enter your home, all the while insulating it from further escaping outside. Moreover, this film can effectively cover up to 5 windows having the dimensions of 3′ x 5′ and block cold air drafts from leaking into your home.
Furthermore, the double-sided tape provided in this kit can be easily applied on a wide variety of surfaces, including painted or finished wood, vinyl, and aluminum. It’s also simultaneously very easily removable and does not strip out any paint or ruin finishes in the process. This tape therefore effectively seals the room and does not allow the warm indoor air to escape or the cold outdoor air to enter.
What Could’ve Been Better?
The adhesiveness of the double-sided tape provided in this kit is a little weak. This, therefore, leads the film to slip off the tape or the tape to come off the wall in just a few short weeks after installation. Hence, chances are, this insulation setup might not last you the entirety of winter like it’s supposed to.

- Made of earth-friendly material

Once applied to the tape, it needs to be patiently heated with a hairdryer and readjusted accordingly to achieve a smooth and stretched-out look. Moreover, this film considerably lowers condensation and prevents the build-up of frost on the windows.
The double-sided scotch tape, on the other hand, has unparalleled adhesiveness that makes it incredibly easy to install and facilitates creating an airtight teal seal around the film. This leads to the formation of a secure seal that neither allows warm air to escape the room nor cold air/drafts to enter.
Hence, the heavy-duty insulation provided by this kit allows you to readjust your thermostat to a low energy-consuming setting. Consequently, this action considerably reduces your energy consumption and thereby lowers the value of your utility bills in the long run.

The clear film in this kit, much like in the Duck Brand above, needs to be smoothed out with a hairdryer after application. However, some customers have lamented saying that it remains wrinkly no matter how much you blow dry it, which gives your windows an overall shabby look.

Moving onto the double-sided tape, it has excellent sealing properties that firmly hold the sheet on all four sides of the window. The adhesiveness on this tape is tempered and therefore it can be put on painted or varnished wood, vinyl frames, or even on metals. The only point to be kept in mind is the surface should be grease-free and clean to provide better adhesion.
Last but not least, this kit comes equipped with a limited lifetime warranty, making it one of the most dependable insulation kits on our guide today.
What Could’ve Been Better?
Most grievances shared by customers are regarding the subpar adhesiveness of the tape. This has ultimately forced users to separately buy tape again from the local stationery stores.

Apart from that, the adhesive side of the tape does not ruin surfaces and leaves no residue post removal, which we love.

Window Insulation Kit Buyer’s Guide
Purchasing the right window insulation kit can be quite a confusing task, especially considering the diverse kinds of kits available in the market. For this reason, we have compiled a comprehensive buyer’s guide listing out all the important factors to contemplate over. These pointers will help narrow down the options so that you can buy the right product for yourself. So, what are we waiting for? Let’s jump right into it!
-
Transparency
The transparency of the film determines how much sunlight can enter the room. The more transparent or crystal clear the film is, the higher the rate of sunlight and heat dispersed within the room. Alternatively, the more opaque it is, the cooler your room stays because of its ability to actively block out sunlight.
Hence it is essential to check customer reviews and the manufacturer’s description to ascertain the transparency level of the sheet. This will enable you to buy a kit according to your personal requirements and insulation criteria.
-
Reusability
Window insulation kits are mainly used only during the colder winter months and hence most of the kits available are meant for one-time use only. However, if buying a kit every consequent year doesn’t sound appealing, you can always invest in one that can be reused for multiple seasons.
While these kits tend to cost more than their counterparts, they considerably reduce your overall expenses. Additionally, they also lower the amount of waste produced and hence are better for the environment.
-
Effectiveness of Sealing
The sealing properties of your window insulation kit are very important factors to consider while purchasing one. This feature determines how effectively your product can keep out cold air from inside your home while keeping the temperature consistently warm. Look for details regarding the airlock properties in order to get a better idea regarding how good the sealant is.
-
Installation and Removal Process
It is essential to look for a window insulation kit that facilitates easy installation and removal especially if you are planning to do it by yourself. This process will mainly depend on how good the materials provided in your kit are since flimsy materials are usually more troublesome to install. Alternatively, you must also look for products that cause the most minimum amount of damage on your windows and walls upon removal.
-
Longevity
The longevity of a product can only be ascertained by comparing the reviews posted by consumers. It is crucial to invest in an insulation kit that is of high quality and lasts for at least a couple of months at a stretch. This will enable you to avoid constantly repurchasing and reapplying the same product in a short duration over and over again.
Verdict
Hence, it is safe to say that window insulation kits are an extremely handy product to have, especially in areas known for excruciating winters. These offer an affordable yet effective solution to keeping the interiors of your home warm and your energy bills down.
However, before we take our leave we wanted to highlight a couple of our hot favorite products. XFasten TWST230 is by far one of the highest performing products on our guide but is also a little expensive to buy.
Duck MAX Strength 284351, on the other hand, is one of the most affordable yet effective kits we have reviewed. We also wanted to specially mention 3M and Frost King V73/9H for their sustained popularity and durable performance in the long run.
So, with that, we come to the end of our comprehensive guide for window insulation kits. Hope this helps. See you next time!
