I Tested And Reviewed 10 Best Tape For Sealing Window Air Conditioner (2023)

I recently had the opportunity to try out this tape for sealing drafty windows, and I must say, it exceeded my expectations. The claim that it leaves no sticky residue when removed is absolutely true, as I found during my testing.

I initially purchased this tape to install air conditioning vents for the summer, and I was pleasantly surprised by its excellent adhesion. The white color also blended seamlessly with my windows, giving it a clean and professional look. However, I do have to mention that although it claims to be tool-free, tearing it without scissors can be a bit challenging. I would highly recommend using scissors for a cleaner and easier cut.

In terms of comparison, I have used both duct tape and painter's tape extensively, and I find this tape to be a preferable option for indoor applications. While duct tape can be purchased in white color for a slightly lower price, this tape stands out with its smaller and closer together reinforcing threads. With approximately 18 lateral threads per inch, it offers better flexibility and ease of cutting compared to duct tape. Additionally, the edges of this tape retain more tackiness, allowing for better adhesion even after removal.

Painter's tape, on the other hand, is cheaper in larger quantities on Amazon but only comes in blue color. While it lacks the reinforcing threads and strong adhesion, it is easier to install and remove. However, for the specific purpose of sealing cracks around a vinyl window for an air conditioner, this tape proves to be the ideal choice.

I recently purchased this weatherproof insulation tape and I must say, I am impressed with its durability. I was a bit hesitant due to its price, but it has proven to be worth every penny.

I used the 2" x 1/4" tape to seal a large gap caused by the installation of a dog door. The tape was easy to cut to the exact measurement of the gap and its adhesive properties were exceptional. It securely adhered to the metal frame of the sliding door and tightly hugged the glass.

The immediate effect was a tight seal that eliminated air flow and outside noise. I was also pleased to find that it prevented bugs and critters from getting in between the glass. Overall, it is an excellent product that met my expectations.

In addition to the tape, I also used it to seal some door gaps on my back door. I even added it to the door frame and it did a wonderful job of sealing off the door. I have not experienced any issues with the tape peeling away from the door frame, thanks to its strong adhesive.

I have been using this tape for several months now and it has held up well. The high density foam has proven to be durable, even with frequent opening and closing of the door. It has also compressed in areas where the door rubs, preventing any ripping.

One thing to note is that the tape comes in a 10' length, which was just enough for my needs. However, if the gap you need to fill is too small, there is a possibility of the door ripping the tape. In such cases, it would be advisable to leave the stripping off in that spot.

I recently purchased this foam tape for my house and I must say, it exceeded my expectations. The thickness of the tape is almost three times as thick as the weather strip that came with my house, which has made a noticeable difference in blocking out the cold air. Despite its thickness, the tape compresses really well, allowing my door to still close with ease.

One concern I had when searching for this product was finding a foam tape that was both thick and easy to use. After reading through numerous reviews, I noticed a common complaint about the tape not peeling off the adhesive easily. However, I discovered a simple solution to this issue. By pinching the bottom of the foam strip, opposite to the adhesive side, the paper easily separates from the foam, making it simple to apply. Additionally, using a good set of shears to cut the tape exposes the sticky side for easy installation.

I specifically used this foam tape to seal gaps around an air conditioner panel that sits in a window. The window itself was uneven, but the thickness of the tape allowed it to expand and fill all the gaps effectively. Unlike the thin foam strips that originally came with the unit, this tape provided a much better solution.

Although my window is old and has peeling paint, I am not concerned about any damage caused by removing the tape in the future. I believe it will come off in one piece, unlike the previous strips I had used.

Conveniently, the single strip I purchased was the perfect size to wrap all the way around the panel. I installed it back in late April/May and it has held up exceptionally well throughout the summer. Overall, I am extremely satisfied with this foam tape. It has provided the insulation and sealing I was hoping for, and I have no complaints whatsoever. I highly recommend it for anyone in need of a reliable and effective foam tape.

I recently purchased this door seal and I am extremely satisfied with its performance. It effectively keeps the cold AC inside and prevents dirt and humidity from entering. The thickness of the seal is just right, not too thick or too thin. Installation was a breeze, although it is important to thoroughly clean the area from dirt and oil before adhering the seal.

The adhesion of this product is strong and reliable. I have noticed zero leaks around my window and back door since installing it. The peel-off process can be a bit time-consuming, taking around 20 minutes per strip, but with some patience and careful handling, it can be removed without any damage.

I also used this seal to replace the old foam seals on the components of my truck's AC. The foam is lightweight yet durable, making it perfect for this application. I had to make some small cuts to ensure clean curves around the corners of the vents, but the seal performed beautifully. It can be re-positioned as needed and provides a secure fit.

In addition to its functionality, this seal has also met my aesthetic requirements. I used it to create a factory-like barrier for upgraded speakers in my MINI Paceman Cooper S. The foam is soft and dense enough for this purpose, giving the speakers a professional and clean finish.

I recently came across this tape while searching for a solution to protect my artworks during transportation. I was hesitant at first, as other materials designed for this purpose were either expensive or added significant weight to the package. However, I decided to give this tape a try and I'm glad I did.

I applied the tape evenly on the edges of my pre-packed canvases and created a grid on both sides. The tape worked perfectly to protect my artwork during transit. I am impressed with its performance and will definitely buy it again. It's worth noting that I have not used this tape for its intended purpose, but it worked exceptionally well for protecting my fragile surfaces.

In addition to using it for my artwork, I also found other uses for this tape. I used it to fill small air gaps and it worked effectively. The adhesive is super sticky, so it's important to be careful and accurate when applying it. I found that slowly peeling back the paper covering the adhesive side as I applied it was the best method. Cutting it to length as I approached the end resulted in a nice clean result. I have only been using it for a month, but so far, it seems to be holding up well.

I also used this tape to seal a gap in my front door, and it adhered very well. It completely sealed the gap, and I'm happy with my purchase. The weather stripping is exactly what I was looking for. I recently installed a window AC and needed this size stripping to block air from coming through a gap. It's dense yet flexible enough to fill the gap and stay in place. I plan on using it in my double hung windows as well.

The foam insulation I purchased was exactly what I needed for my air conditioning unit. It fit perfectly in my window frame, although I did have to add some additional foam on the right side to compensate for the plexiglass not being cut accurately. However, this extra foam is hidden when the unit is in place, so it's not an issue. I appreciate that the adhesive is sticky enough to hold the foam securely, but can also be easily adjusted without tearing the foam.

In terms of performance, this foam insulation does an excellent job of keeping heat and cold air inside. It effectively insulates the space and helps maintain a comfortable temperature. I was able to complete my project with plenty of foam to spare, even after covering holes from the air conditioning mount.

I specifically wanted a lightweight and airy insulator that wasn't overly dense or rubbery in texture. This foam fits the bill perfectly. It has a fluffy and airy texture that does the job without promoting mold growth or trapping humidity. Its lightweight nature allows it to dry quickly if it does get damp, which is a bonus.

However, I did notice a slight perfume smell with this foam, similar to products from Bath and Body Works. Personally, I prefer to avoid any scented products in my home, so I decided not to use this foam. Instead, I returned to Amazon to find a different option. If you're not sensitive to smells and prefer a fluffy and airy foam insulation, this product could be a great choice for smaller indoor projects such as doors or windows.

On a positive note, I found this foam insulation to be easy to cut to the desired thickness or length. It was a breeze to customize and fit it to my needs. I primarily used it to keep critters out and reduce wind noise from a small window opening, and it has done a fantastic job so far. The adhesive sticker on the foam is optional, and I chose to keep it in place so that I can remove the foam if needed for deep cleaning. Overall, I highly recommend this foam insulation for its versatility, ease of use, and durability.

I also purchased this foam insulation to adhere to the ceiling of my garage, as my trunk touches it when open. The thickness of the foam is perfect for absorbing the "shock" of my slow-opening hydraulic trunk door. It was effortless to cut and install, and it has held up well in a humid underground garage for over a month now. I am pleased with its performance and would recommend it to others in a similar situation.

The foam insulation worked great for filling the small spaces between the roof and wall panels in my shed. I didn't want to use sticky insulation foam, so this product was a perfect alternative. It doesn't have adhesive, so keep that in mind. However, it easily fills holes when jammed into small spaces. This is a much better option if you don't want to damage what you're filling with permanent foam.

Baseboard heaters are a hassle and take up too much space in my tiny apartment. They render two full walls unusable, making it impossible to place furniture within a foot of the heaters as recommended. However, this foam insulation proved to be the perfect solution for filling the gaps between the baseboard heaters and the floor. I ordered eight packages and filled all the gaps, making cleaning and finding cat toys much easier. Although this may not be the intended purpose for this foam insulation, it works perfectly for this use.

I purchased this foam insulation to seal the gap between my window and the air conditioner. The bottom window is left open for the air conditioner, creating a large gap at the top where air can come through. This foam insulation is the perfect size to tightly seal the gap. I simply pushed it in without the need for glue. This insulation effectively prevents hot air and bugs from entering through those small spots.

I recently purchased a window seal kit for my portable AC unit and I must say, it exceeded my expectations. As someone who has been working from home during the Covid pandemic and experiencing the intense California heat wave, I needed a solution to connect my AC unit to my windows. After searching on Amazon for options, I came across this particular window seal kit and decided to give it a try.

First of all, the delivery was incredibly fast, which was a huge plus for me as I wanted to get it as soon as possible without having to leave my house. The installation process was a breeze thanks to the adhesive Velcro and zipper included in the kit. I was able to easily attach the kit to my windows without any issues.

What impressed me the most was how well it worked. The window seal kept the cool air from the AC unit inside my room and prevented any hot air from entering. This was particularly important for me as I have vertical outward opening windows controlled by a crank, which can sometimes pose a challenge for installing such kits.

Furthermore, when the fall season arrived and I needed to store my portable AC unit, the window seal was easy to fold and store as well. I even decided to leave the Velcro on the window for convenience, knowing that it will only take me a couple of minutes to reinstall it next summer.

The product itself is of high quality, made from a waterproof material which is definitely a plus. It also comes with a clear manual that provides easy-to-follow instructions for installation.

I recently purchased this portable AC window seal and I must say, it has been a game-changer for me. Living in a small bedroom in NYC, I have always struggled with finding a solution to keep my room cool during the hot summer days. While I had a ceiling fan, it was not sufficient enough to combat the heat.

I was hesitant to invest in a portable AC unit because of the need to vent the hot air out, which seemed like a hassle given the layout of my room. However, after doing thorough research, I came across this product and decided to give it a try. And boy, am I glad I did!

The installation process was a breeze. Following the instructions provided and ensuring that I cleaned the surface properly, I was able to install the seal without causing any permanent damage to my balcony door. The seal comes with zippers on both sides, allowing me to have the opening on the opposite side, which works perfectly fine for me. While it may not be 100% airtight, it does a great job of preventing the heat from coming back in.

One of the best features of this seal is its versatility. I can easily unzip it and use my door without any obstructions when the AC is not in use. I usually keep one side pinned open by closing it in the screen, or I can even use the leftover Velcro to create a small square to keep the flaps open. Once summer is over, I can simply take down the white part and store it for next year. It is a convenient and practical solution for my needs.

In terms of sizing, I would recommend ordering a size up if you are unsure about the perimeter of your window. I have a 430cm window, and the 500cm seal fits perfectly. I used the Velcro tape to tuck away the excess at the tail edge, which worked like a charm. To make the installation even easier, I folded the seal in half to find the midpoint and mounted it first to the center of the open-most edge. For my window style, I mounted the zipper side to the outward pane part of the window and the long edge to the frame. Folding the inner corners helped create a better seal.

I am extremely frustrated when gas stations play ads without any option to mute them while pumping gas. The gas pump speaker is small, measuring around 2 inches wide and 3 inches long, in my area. However, I have found a solution to block out the audio portion of these ads. By cutting the foam gasket tape into 3.5-inch long sections and placing it over the speaker, I am able to completely block the sound. The adhesive on the tape is sticky enough to hold it in place for the duration of my fill-up, which is usually around five minutes or less. The only downside is that the paper backing is quite difficult to remove. To overcome this, I cut the foam with the backing off and leave an inch of backing longer, providing something to grab onto when I need to remove it at my next fill-up.

The adhesive on this foam gasket tape also proves to be useful for other purposes. I used it to fill a gap between a screen door and the door jam, where there was a 3/4 inch gap. The tape compressed nicely to fill the gap tightly, effectively keeping out bugs and lizards that are common in my yard. Since using this tape, I have not had any unwanted visitors coming in overnight. The stickiness of the adhesive is impressive, and I appreciate that it holds firmly in place. However, I can imagine that removing it may be a challenging task. Although I have not had to remove it yet, I believe it could potentially be a chore.

The foam gasket tape comes in two strips, each measuring about 6 feet in length. The cover on the adhesive peels off easily, leaving the sticky part exposed. This makes it convenient to cut the tape to the desired size and shape before removing the backing and sticking it properly. It is important to ensure proper placement as I am unsure if it will easily pull away and restick. To avoid any issues, I removed sections of the white strip as I progressed along the doorway.

On a different note, I purchased this product to seal my windows and reduce street noise. While it doesn't provide a 100% reduction, it does significantly reduce the noise to a level where I can rest comfortably. The remaining noise is more like white noise, which is not bothersome.
