I Tested And Reviewed 10 Best Insulation For Crawl Space Ceiling (2023)

I recently purchased the Smart Shield reflective insulation for my metal roof and I must say, it exceeded my expectations in keeping the heat off my house. Despite ordering a larger size that was undeliverable, the company was quick to provide a refund and I ended up ordering directly from Smart Shield's website, which was a seamless experience.

The product itself is only 3mm thin, but don't let that fool you – it is incredibly effective. I found that installing it on cloudy days (not rainy) was the best option, as the sun's reflection can be blinding and the heat radiating off it can be intense on a hot summer day. However, once installed, it significantly reduced the heat transfer and made a noticeable difference in the temperature of my home.

I particularly appreciate that the Smart Shield insulation is made of foam instead of bubble wrap. This not only makes it easier to work with but also provides a more durable and long-lasting solution. Cutting the foam with a utility knife or scissors was a breeze, and I found that attaching it to my windows using packing tape worked well. The white backing was also beneficial for me, as it complied with my HOA regulations and helped cool the west-facing section of my house, which is subjected to intense Texas heat.

Additionally, I used this insulation to insulate my travel trailer and was equally impressed. It effectively blocked heat transfer and made a noticeable difference in maintaining a comfortable temperature inside. The lightweight nature of the insulation made it easy to cut and attach using a staple gun, without the worry of popping air bubbles. I even used it to create a skirt around my RV, which served its purpose effectively.

The attic stairs insulation cover is a cost-effective home improvement solution that offers remarkable benefits. The reviewer found it to be an affordable option to control temperature and reduce energy consumption throughout the year. By sealing the cracks with T20 staples and 3M tape, the reviewer was able to effectively prevent air leakage and optimize their HVAC system's performance.

The insulation cover exceeded the reviewer's expectations in terms of its functionality and durability. Despite the attic entrance being slightly smaller than the cover's dimensions, the flexible material allowed for easy installation and a snug fit. The cover's design, although not rigid, provided stability and effectively retained temperature control. The presence of two zippers allowed for convenient access from both directions.

The reviewer emphasized the insulation cover's ability to maintain temperature efficiently, even with its thin material. It effectively prevented heat loss during the winter and kept the house cool during the summer. The high-quality zipper and solid stitching contributed to the cover's overall durability.

For those with a house that loses heat easily during the winter, this attic stairs insulation cover is an excellent option. Its sturdy construction and reliable insulation properties make it a worthwhile investment. Even if your attic opening is slightly smaller than the dimensions, the cover can be easily adjusted to fit securely.

I recently applied this thermal barrier to my un-insulated garage and I must say, it has made a significant difference in the temperature. While it is important to note that this is not insulation in the conventional sense, it acts as a thin thermal barrier by reflecting sunlight and heat, preventing the garage from heating up excessively. This has allowed me to comfortably work in the garage even during hot summer days.

One of the advantages of this reflective barrier is its ease of installation. I was able to apply it to the inside of my garage door using double-sided tape, something that would not have been possible with traditional insulation. I also stapled it between the exposed studs and created a roll-up "drape" for half of the garage. These measures have noticeably reduced the temperature inside the garage during summer.

Prior to using this reflective barrier, even with a portable air conditioner, the garage was unbearable if the outside temperature exceeded 85 degrees. However, after applying this product, I have been able to maintain a temperature below 80 degrees inside the garage, even when it's up to 100 degrees outside.

Another reason I chose this product was to replace fiberglass insulation that had been damaged by vermin over the years. The rats had been making nests in the fiberglass, leaving a lingering smell of urine. I wanted to prevent them from returning and this reflective barrier has successfully achieved that goal. I even doubled it up to meet the P23 standard, and my house is now better insulated than it was 30 years ago when it was new. Installing it with an Arrow staple gun was a breeze, and I had no issues with fiberglass irritation.

I also decided to add this thermal barrier to my west-facing garage door, and the difference it has made is astounding. The side-by-side comparisons show almost a 40-degree difference between the door I haven't treated yet and the one I have completed. This will undoubtedly contribute to the overall insulation of my house.

In combination with 1" EPS insulation, I used this reflective barrier to insulate my 20'x8' garage door. The result has been remarkable, with the temperatures staying in the 60s overnight, even when it's freezing outside. The flexibility of the material made it easy to tuck into corners and rails, keeping the foam insulation in place without the need for glue or double stick tape.

I recently purchased the attic stairway insulation covers and I am extremely satisfied with my purchase. The installation process was a breeze and the results are fantastic.

First of all, let me start by saying that the cover fit perfectly onto my attic ladder. I was initially hesitant about whether it would fit properly, but it exceeded my expectations. I even thought about leaving it as it was without stapling it, but I decided to secure it in place for extra peace of mind.

The installation process took no time at all. I was able to complete it before my morning coffee was finished brewing. It was a simple task that anyone can do, even with limited hand strength or experience. I was particularly impressed with the ease of adjusting the stapler to ensure a neat and tidy finish.

Since installing the attic stairway insulation covers, I have noticed a significant reduction in the amount of hot air that used to escape from my attic. This has made a noticeable difference in the temperature of my hallway office and has even helped to reduce the frequency at which my thermostat is triggered.

Not only does the cover help to regulate the temperature, but it also seals any air gaps that were present in the original stairway assembly. This has had the added benefit of reducing the amount of dust that enters my home through these gaps. As a result, my house is cooler and cleaner.

I must admit, I wish I had installed these attic stairway insulation covers years ago. They have made such a positive impact on the comfort and cleanliness of my home. With the scorching temperatures outside, I am grateful to have found a solution that is both affordable and effective.

I highly recommend the attic stairway insulation covers to anyone looking to improve the temperature regulation and energy efficiency of their home. The installation process is simple, the fit is perfect, and the results are outstanding. Don't wait any longer – give your home the insulation it deserves.

I recently purchased this insulation for my woodshop in Alabama, where the summers can get quite hot. Initially, I used it to insulate part of my garage door, and I was amazed by the results. Even with temperatures in the 90s outside, there was an 8-degree difference between the bare door and the insulated area. This insulation effectively prevented the heat from radiating into my garage space, making it much more comfortable.

I was so impressed with the performance of this insulation that I decided to use it on my hot water heater as well. In the winter, my hot showers would be cut short due to the heater not being in a climate-controlled room. However, since wrapping the heater with this insulation, I have noticed a significant improvement. The hot water heater doesn't have to work as hard to maintain the water temperature, resulting in longer showers and potential energy savings.

I also made sure to cover the top of the tank, as heat rises and can escape through the pipes. The appearance of the insulation on top doesn't matter as much as its functionality, and it does its job perfectly.

If you have a hot water heater in a non-climate-controlled room and struggle with maintaining hot water during the winter months, I highly recommend using this insulation. It has made a noticeable difference in my showers and will likely result in lower energy bills. I plan on keeping mine wrapped year-round for optimal performance.

I recently purchased this product and have been extremely satisfied with its performance. I used it on my motorhome, which is exposed to direct sunlight all day long. Prior to using this product, the temperature inside my RV would reach a scorching 95 degrees Fahrenheit by 3 pm. However, after applying this insulation, the temperature now only reaches a comfortable low 70 degrees at the same time. It has made a significant difference in reducing the heat inside my motorhome.

Additionally, I found this product to be highly effective when wrapping my flexible ducts in the attic. The foil is thick and durable, ensuring that it holds its shape and provides the necessary insulation. I was able to wrap it around the ducts easily, securing it with aluminum tape and using Dap silicone to keep the edges down. After a month, it is still holding tight, demonstrating its longevity and effectiveness.

I was pleasantly surprised by the sturdiness of the aluminum foil. I had concerns about it tearing from the staples, but the fibers in the material made it very sturdy and resistant to tearing. It required a utility blade to cut through it, further emphasizing its durability. I used it in a sauna project, and it maintained the heat well even after the fire had been extinguished.

Furthermore, this insulation proved to be easy to work with. It did not rip easily and could be easily cut using a utility knife. This made the installation process hassle-free and allowed for precise measurements and cuts.

Living in a tropical region, I also decided to use this product on the ceiling and walls of my shed, as well as on my house ceiling. The insulation has successfully maintained a perfect temperature in the shed and has kept my house cool even under direct sunlight. Its ease of cutting and hanging made the installation process quick and efficient.

The vent covers we purchased for our new house were a great solution to our problem. The vents in our house were not completed correctly, and we needed a cover that would not only fix the issue but also look aesthetically pleasing. This product turned out to be exactly what we needed. The quality of the covers is excellent, and they serve their purpose effectively.

One thing to note is that I was not aware that the covers were made of plastic when I placed the order. While they are a bit flimsy, they still serve their purpose well. However, it would have been helpful to have this information upfront.

Despite this minor drawback, I am planning to replace all my vent covers with this product. I am very impressed with how they look and function. They are easy to install, and I couldn't be happier with the results.

In terms of value for money, these vent covers are exceptional. I have seen other products of lesser quality that cost more. I genuinely recommend this product to anyone in need of vent covers. They are not only easy to install but also fit perfectly according to the size provided in the product description.

I recently purchased this attic insulation product and I am extremely pleased with the results. Within just an hour of installation, I noticed a significant drop in temperature in my attic. This is particularly beneficial for me as my heat pump is located in the attic. Not only did the attic temperature decrease by 20 degrees, but I also noticed that my air conditioning ran cooler as a result.

Additionally, the effects of this insulation were not limited to the attic alone. The second floor of my house also felt noticeably cooler, and even the ceiling temperatures dropped. This demonstrates the effectiveness of the product in regulating temperature throughout the entire house.

One aspect that I would like to highlight is the installation process. It is important to note that this insulation should not be laid on top of the insulation, but rather installed on the underside of the roof joists to allow for an air gap. Despite this requirement, the installation was relatively straightforward and hassle-free.

Moreover, I was pleasantly surprised by the durability of this product. It is significantly more durable than I had anticipated. It is still easy to cut, yet it does not tear when hanging or laying it out in the attic. The shiny nature of the insulation adds to its appeal.

While I have yet to experience the full benefits of this insulation during the heat of the summer, I have high hopes that it will perform exceptionally well. Given its durability and ease of installation, I am confident that it will continue to provide efficient insulation for my attic.

In addition to its use in attics, I also utilized this product to insulate a garage. I used it as an interior wall vapor barrier and I must say, I was very impressed with its durability during installation. It held up well while attaching it to the studs with 3/8" staples.

One unexpected benefit of this insulation is its impact on my power bills. I initially installed this product to create a barrier between the roofing sheeting and the attic, as the shingles were causing issues. However, to my surprise, my power bills decreased by approximately half after the installation. This is a significant saving and I cannot recommend this product enough.

I purchased this product to help keep my camper warm during the harsh winter. I decided to skirt my camper with this insulation as an extra layer of protection. I have an enclosed heated underbelly, but since I'm living in it all year round, I wanted to take extra precautions. I doubled up the insulation on the northside, northeast, and northwest sides. The installation process was very easy and the product was easy to work with. I'm curious to see how well it will perform in the coming winter.

I bought this insulation to install on the inside of my garage door so that I can add air conditioning during the summer. I needed two rolls of this insulation, but with some creativity, I was able to make it work with the last two squares on the door. The installation process was super easy – just cut and paste. I used high-quality two-sided carpet tape and it holds up well even in damp evenings and hot days. I wish I could have attached a photo to this review, but unfortunately, that option is not available.

I made templates from paper and cardboard for my 2010 Chrysler Town & Country and this insulation fits perfectly in the back and sides. I will need a wider roll for the windshield. I plan on buying more of this insulation for my other cars and doing the same thing. I cut it close enough for a tight fit and it makes the inside of the car dark even in full daylight. I recommended this product to a friend who has a pop-up trailer and she plans on getting some as well.

I purchased this insulation as additional insulation for my PEX water lines. I cut strips and taped them around the PEX 1/2" R3 insulation, resulting in an R11 insulation level, along with the normal ceiling insulation. This super-insulation helps reduce heat loss on the recirculation system. I also discovered that it works great behind electrical gang boxes, providing better insulation than simply stuffing R13 insulation behind the box. While spray foam also works, it may push the box out during expansion. I will be using the remaining insulation to wrap around the water heater.

I installed these insulation sheets in my RV windows and they work great. There is a noticeable difference in the room before and after installation. I would definitely recommend these and purchase them again when needed.

I recently purchased this insulation to line the interior of an outdoor house for a neighborhood cat that often wanders through my yard. I was concerned about the cat being exposed to the cold and wet weather, so I decided to provide a warm spot for her. I cut the insulation to fit each interior side, as well as the bottom and top, and secured it in place with duct tape. Now, the cat has a cozy and insulated shelter whenever she needs it.

Additionally, I found that this insulation has helped me save on energy costs. During the summer, it reduced the temperature inside my house by 5 degrees when the air conditioning was on. Although I cannot provide an exact figure for the savings, I can confidently say that the insulation has already paid for itself within a week. While it does limit the visibility through the windows, it effectively blocks the intense afternoon sun, especially when the temperature exceeds 100 degrees.

I have also compared this insulation to another brand that I purchased from Home Depot, and I must say that this one is far superior in quality. It is thicker and much easier to work with. I have used it to insulate windows with AC units as well as an old aluminum-framed back room window, and it has made a noticeable difference in temperature regulation.

Not only is this insulation easy to manipulate and cut, but it has also proven to be highly effective. We have a finished basement in our house, and the air conditioning ducts were not insulated, resulting in poor energy efficiency. However, after using this insulation, we have noticed a significant improvement. Our AC no longer runs as long, and the air coming out is now ice cold. I am confident that it will also help with heat retention during the winter months. Overall, this has been a great purchase for us.
