I Tested And Reviewed 10 Best Spray Foam Insulation For Attic (2023)

I recently purchased this insulation spray for my shop and I must say, it exceeded my expectations. The application process was easy, as long as you follow the instructions on temperature and shake the cans well. I made sure to wear personal protective equipment and long sleeves to avoid any contact with the skin, and I'm glad to report that it did not come off the skin easily.

One thing that stood out to me was the effectiveness of the product. I read some reviews mentioning issues with the product not dispensing correctly, but I didn't encounter any such problems. Out of the 24 cans I bought, all 24 worked wonderfully. I initially purchased 12 cans just to test the product, and it met my standards perfectly. In fact, I was so impressed that I ended up buying a total of 36 cans to complete the insulation for my entire shop.

The temperature range in my shop varied from 130 degrees without insulation to a comfortable 85 degrees with just a blower running. The spray foam helped regulate the temperature effectively, and I couldn't be happier with the results. In fact, my best friend is now planning to use the same product for his shop.

I had a smooth experience using this spray foam. I went through all 12 cans without any issues, and I didn't have to clean the gun until I was done. The expansion of the foam was good and the coverage was fairly even. I was working on an unvented roof over two layers of closed cell foam board, and the spray foam adhered really well. I did go thicker in some areas (around 3 inches), which caused a bit of sagging, but nothing fell off. It was a bit challenging to get the foam to go straight up next to the ridge, but it was possible when the can was new. The final hardness of the foam was between open and closed cell foam, which was satisfactory for my needs. Overall, I was very happy with the results and I will definitely be using this product again.

I used this insulation spray to insulate a skylight tunnel and I found the application process to be straightforward. The product came with limited instructions on the can, so I watched a video on YouTube beforehand, which was helpful. Six cans were enough to cover approximately 120 square feet with about 2 inches of foam. The expansion of the foam was around 2 times its application depth, but it took a bit longer to cure due to the lower ambient temperatures. Instead of a couple of minutes, it took around 15 minutes to fully cure. Overall, I am very pleased with the product and the results it provided for my skylight tunnel.

The Spray Foam Froth Pack is a convenient and effective solution for insulating your garage. With a coverage of 1" thickness, it provides great insulation and seals any gaps or cracks. The kit comes with two 50lbs tanks, which can be a bit heavy to handle, especially if you're working on a tall ladder. However, for a regular ceiling in a house, a short stepladder should suffice.

The kit includes two types of nozzles, with the blue ones offering a wide and even fan spray pattern. Users have noted that these nozzles provide better results compared to the general-purpose ones, which tend to leave a rougher finish. It's worth mentioning that additional blue nozzles are needed, as they tend to run out quickly.

The foam itself dries incredibly fast, within 5 minutes, making the application process relatively quick. However, it's important to note that once you start spraying, you need to keep going without any breaks, as the nozzles can easily clog up within a minute of stopping.

While the foam does its job effectively, it does come with some drawbacks. The fumes emitted during the application can be strong, so wearing a respirator is highly recommended. Additionally, the foam is difficult to remove from skin, so wearing gloves is advisable.

In terms of coverage, it's important to consider that you may need more foam than expected. Factors like overlapping and edges can consume additional foam, so it's recommended to budget 50 to 100% more than the surface area multiplied by 1 inch thickness.

I am extremely satisfied with this spray foam kit. It is incredibly easy to use and clean the gun, even for someone like me who has never used a spray gun or single part insulating foam before. I only wish I could get more of it!

The kit I received was comprehensive and included everything I needed, except for the voc N95 and the tyvek suit. Although it wasn't actually missing, I was pleasantly surprised to find that the kit came with gloves, booties, safety glasses, nozzles, and the gun. The water activation on the rim joist resulted in a uniform, thick first coat. I was able to apply subsequent coats without water, and the spray was very easy to control, resulting in very little waste. I was able to easily cover my room joist in 3-6" of foam, joining some existing pink board, and sealing it all up with some pro-grade products to encapsulate my crawlspace. The area already smells better, and I would definitely buy this kit again for future projects, such as insulating the attic of my cape cod home.

This product exceeded my expectations. I used it to insulate an 8' wide and 8' tall garage door (5 sections) with just 3 cans, averaging 3/4"-1" in most places. It only took me 15 minutes, and the fan tip worked well. It wasn't messy either, as long as I got my speed and distance right. I will be using it next on a 16' 5 section door, and I recommend changing the tip after every can. I used the cleaner provided to preserve the gun, and it didn't take much to clean it out. The only downside is that I expected it to expand more, but I haven't had time to check if my temperature drops.

This is an excellent product! It does require some skill to learn the material's capacity, but once you figure out how much you can spray before it sloughs off, the job becomes much more pleasant.

I only did a trial on walls, but I found that this brand gave me more foam than the others I've tried, and it sprayed much more evenly. I can't say for certain if any of these products actually give you the board feet they claim, but I will spray a bunch when I'm ready and write another review. It costs about $1 per board ft and it's closed cell, which is an unbeatable price. If you're looking for the expanding kind, this isn't it. This product is meant to seal your house. In my current review, I can confidently say that it's awesome and offers great value at a great price. If you were to call any contractor, they would likely charge you more for open-cell foam, which is usually closer to $2 per board foot.

With all that said, kit foam doesn't seem to get quite as rigid as machine-sprayed closed-cell foam. However, considering the savings, I will be using this product to insulate my house myself.

I recently used the insulating foam kit for the first time, and I must say, I was thoroughly impressed with its performance. The kit came with all the necessary components, including the gun, gloves, booties, safety glasses, and nozzles. The only minor setback was the missing VOC N95 and Tyvek suit, but it didn't hinder the overall experience.

Using the foam was a breeze, thanks to its easy-to-use and clean gun. After shaking it well, I applied a uniform thick first coat by activating the water on the rim joist. Surprisingly, subsequent coats went on smoothly without water. The spray was highly controllable, resulting in minimal waste. I was able to cover my room joist, joining some existing pink board, and effectively seal my crawl space. The improvement in the area's smell was noticeable almost immediately.

One aspect that exceeded my expectations was the coverage. I used the foam to insulate an 8' wide and 8' tall garage door with just three cans, averaging 3/4" to 1" thickness in most places. It only took me 15 minutes, and the fan tip worked exceptionally well. The process was relatively mess-free, as long as I maintained the right speed and distance. I also appreciated that the gun cleaner was effective in preserving the gun, and cleaning it out was a breeze.

While the foam didn't expand as much as I initially anticipated, it still provided satisfactory results. It does require some skill to understand its capacity, but once you get the hang of it, the job becomes much more enjoyable. Compared to other brands, this one seemed to deliver more foam and sprayed more evenly.

In terms of value, this kit is truly excellent. Costing around $1 per board foot and being closed-cell, it offers great affordability. If you're looking for expanding foam, this might not be the ideal choice, as it focuses more on sealing your house effectively. However, for the price, it's hard to beat.

It's worth mentioning that kit foam may not get as rigid as machine-sprayed closed-cell foam, but considering the significant cost savings, I'm more than willing to tackle insulating my entire house with this product.

I recently used the Sprayman spray foam product to insulate the interior of my 12 x 20 barn roof shed, and I must say, I was thoroughly impressed. I initially had concerns about the cost and my ability to spray it effectively, but those worries were quickly put to rest.

The application process was surprisingly easy and straightforward. It only took me 29 cans to cover both the walls and roof of the shed. The coverage was nearly as advertised, which is quite impressive considering my lack of experience in using spray foam. I was able to achieve excellent results with minimal touch-ups required.

One tip I would highly recommend is investing in a paint suit with a hood and a quality organic compound respirator. This will ensure your safety and make the application process more comfortable. Additionally, don't rush when replacing an empty can with a new one. Take your time and work methodically to prevent any clogs or mishaps.

I also used this spray foam product inside a metal 10 x 10 shed that covers my well. The entire process took me less than an hour to complete, even though I am older and move at a slower pace. I simply cleaned the walls and sprayed water on them before applying the foam. The product sprayed on easily, and the clean-up was a breeze thanks to the cleaner spray can included in the kit.

In terms of value, this spray foam product and application system far surpass other options such as the Froth-Pak products. For just a slightly higher cost, I was able to purchase six cans of Sprayman foam and double-coat the necessary surface area, using only three cans. Each can is advertised to cover 20 board-feet at a thickness of 1", and while that claim may be slightly optimistic, I was still satisfied with the coverage I achieved.

What impressed me the most was the fact that I still have three cans left after completing the project. The kit also includes a can of foam cleaner, which can be used to clean the high-quality spray gun for future use. This adds to the overall value and convenience of the product.

I also used the spray foam kit for a bathroom remodel, specifically to soundproof the wall between the shower and living room. Additionally, I had some old termite damage that had weakened the wall. The spray foam did an outstanding job in both regards. The sheet rock in that area is now 3-4 times sturdier, and there is absolutely no noise transmission from the bathroom to the living room. I only wish I had used this product in every wall of my home.

I recently used this product and I have to say, it works incredibly well. It delivered on its promises and I was satisfied with the results. However, one drawback is that it contains some harmful chemicals, which is a concern for me. I hope there are no side effects from using it.

In terms of application, I found that doing a light coat first on the entire walls and then going back for a second coat worked best, similar to painting a vehicle. I used it for a major repair on my RV, aiming to improve its R factor and seal the work. I still have more work to do on my RV and I will definitely be using this product again for the rest of the project. Thank you for creating such a great product.

While the product itself met my expectations, I was disappointed with the packaging. Part of my order had fallen out prior to delivery due to poor packaging. However, I must commend the company for their prompt response. They apologized for the inconvenience and immediately sent out the missing items. Their customer service was commendable in resolving the issue.

I recently used the Sprayman foam spray for a barn roof shed, and I must say, I was pleasantly surprised by the results. I was initially concerned about the cost and my ability to spray it properly, but it turned out to be a breeze. I only needed 29 cans to cover the walls and roof, which is almost exactly what the product claims to cover. This impressed me, especially considering my lack of experience in using spray foam.

One thing I would recommend is investing in a paint suit with a hood and a quality organic compound respirator. These precautions are essential for your safety. Additionally, I never rushed when replacing an empty can with a new one, and I didn't experience any clogs. I took my time and went through the process methodically, climbing up and down ladders without any issues.

I also used this spray foam product in a smaller metal shed that covers my well. The application process took less than an hour, and I found it incredibly easy to use. The foam sprayed on smoothly, and the clean-up was a breeze with the included cleaner spray can.

In terms of value, this spray foam and application system exceeded my expectations. Compared to other options like the Froth-Pak products, the Sprayman foam offered superior value. For just a little extra money, I was able to buy six cans and double-coat the surface area I needed to cover, while other products would have required more cans. Each can is supposed to cover 20 board-feet at a thickness of 1", and although this claim is slightly optimistic, I was still satisfied with the coverage I achieved.

I also used the spray foam to soundproof a bathroom wall during a remodel. I had some old termite damage and wanted to maintain the wall's integrity. The spray foam did an outstanding job, making the sheet rock 3-4 times sturdier in that area. Additionally, it effectively blocked any noise from traveling through the wall, providing excellent soundproofing. I only wish I had used this product in every wall of my home.

I recently used this foam insulation for soundproofing purposes on my hollow doors and sealing the edges of my garage walls. I must say, I am quite impressed with the results.

Firstly, when it comes to soundproofing, I didn't measure the exact decibel reduction, but there is a noticeable improvement in muffling sounds from other rooms. It may not be perfect, but it is a cost-effective alternative to replacing all my doors with solid ones. Additionally, the added weight of the foam gives the doors a nice feel when opening and closing.

For sealing the edges of my blue foam insulation in the garage walls, this foam insulation worked perfectly. It provided a tight seal and ensured that there were no gaps or air leaks.

One of the standout features of this foam insulation is its ease of use. Unlike disposable cans with tips that often cause problems, this foam insulation is user-friendly and doesn't require using the entire can in one go. This flexibility is a major advantage, especially when compared to individual cans that are often difficult to use even later in the day.

Furthermore, the effectiveness of this foam insulation is commendable. I had a rat problem in my attic and after using this insulation around the house, particularly on corners of the roof, I was able to eliminate the issue. It is truly amazing how well this foam insulation works against pests.

In terms of cost, it is worth noting that purchasing this foam insulation online is slightly cheaper than buying it at a local big box store. This is particularly beneficial if you require a larger quantity, such as when insulating window weight pockets. I found that drilling 5/8" holes and using about 5-8 seconds of foam per hole resulted in a nicely filled pocket. To ensure the foam doesn't overflow, I plugged each hole with a paper towel.

The Frothpak insulation product is a great option for enclosing a patio and transforming it into a sunroom. Despite initial apprehension, the process of using this product turned out to be fairly easy. The only difficulty encountered was in mixing the product in the canisters before spraying it. However, if you have experience with spray paint and achieving an even coat, this task should come naturally.

The application process is quick, and it is important to protect the areas you do not want the foam to adhere to, such as windows, floors, and 2x4s. The foam dries rapidly and becomes very rigid. While it is possible to scrape off any excess foam using a putty knife, it is advisable to cover floors and windows to prevent any unwanted mess.

In terms of performance, the Frothpak insulation adheres well and does not easily glob up or roll off the gun, causing a mess. Unlike other spray foam products, it does not create excessive overspray that can settle on surrounding surfaces. With a capacity of 200 board feet, the product delivers exactly what it promises.

The customer service provided by the seller is commendable. When the buyer requested an earlier shipping date to meet inspection deadlines, the seller promptly responded and shipped the Frothpak. Although the product covered most of the required square footage, an additional purchase was necessary to meet code requirements. The only minor complaint is that when the product runs low and spraying continues, it can create a messy situation that does not cure properly. However, this issue is not the fault of the seller and does not detract from their excellent service.

I recently used this foam kit for insulating my basement walls and I am extremely happy with the results. I would highly recommend this product for anyone looking to seal and insulate their basement or any other space.

Firstly, the product is very easy to use. The kit comes with clear instructions that are easy to follow, although I would advise reading them thoroughly before getting started. The foam is forgiving in terms of time between squeezing the trigger, which is great when you need to move around or reposition a ladder. The coverage area is impressive, and I found that a little goes a long way, making it a better dollar value compared to other products I've used.

The shipping was fast and inexpensive, which was a pleasant surprise. The product exceeded my expectations in terms of ease of use and performance. It did a fantastic job of sealing and insulating my basement walls, and the end result looks great. The foam expands about an inch once it dries, and there is no smell after a day or two.

I would like to mention that this foam is very sticky, so it is important to wear coveralls, a hood, and gloves to protect yourself. It can be difficult to remove if it gets on your skin or hair. Additionally, it is recommended to use a respirator when working in confined spaces.

One of the standout features of this foam kit is the ability to pause and resume the application. The nozzle design and the extra tips provided make it easy to disconnect and reconnect without any issues. I had to wait a week between applications, and it was a seamless process. The foam cured quickly, and I experienced no problems when I came back to continue the job.
