Product Overview

Choosing The Right Insulation

Faced Insulation


Face insulation uses kraft paper vapor barrier to control moisture transmission between 
walls and floors 

*Check your local building code for requirements
Unfaced Insulation


Unfaced insulation does not have a vapor barrier; used over existing insulation in the attic, or where moisture control is not needed

Rolls Insulation


Continuous rolls are easy to transport and can be cut to length; great for large areas

Batts Insulation


Come in pre-cut lengths for faster installation and each package contains more square feet than rolls; ideal for framed cavities

The attic is one of the easiest places to add insulation to improve the comfort and energy efficiency of your home. AttiCat Expanding Blown-In Insulation is designed for your attic insulation project in new or existing homes. The specially designed AttiCat machine conditions the insulation by adding millions of tiny air pockets that give the material its insulating power and energy-saving R-value over time. Blowing the insulation should take less than 1.5 hours and the whole job can be completed in less than 4 hours based on a 1,000 sq. ft. attic at R-30.

  • 1-bag coverage: R19 = 109.5 sq. ft. / R30 = 68.5 sq. ft. / R49 = 39.5 sq. ft.
  • AttiCat insulation maintains R-value over time and provides temperature and sound control
  • Self-feeding system provides complete coverage, even around pipes, wires and outlets
  • No mess, the insulation releases and expands completely inside machine
  • Minimum 50% certified total recycled content
  • Provides easy clean-up because machine does the work for you

will the machine that blows the insulation in also suck out the insulation?

Asked by: Anonymous
Yes. All fans that blow on one side, will suck in on the other side.

Since the product R-Value is measured by height where can I find Insulation Depth Markers?

I cannot find these on the Home Depot website. They seem critical for applying the product correctly.
Asked by: Todd
Usually they are hanging in the isle next to the insulation. They are free. I put painter's tape around verticals to mark the height. It is much easier to read when blowing insulation than a scale. R3 per inch, so 20" up for R60.

Will the machine fit into a Expedition if broken down?

Asked by: Elijah426
Probably so... but why would you want to put it in a broken down Expedition? Shouldn't you get it fixed first?

AttiCat Fiberglass Expanding Blown-in Insulation System is rated 4.7 out of 5 by 192.

The work to blow the insulation in in our attic with a 4 &12 pitch to the roof was a bit of a challenge getting about but the ability to blow the insulation 10-15 feet out made getting the product under the low sections of the rafters a breeze. I blew in 30 bales and have between R44 and R49 in our attic for less than $1K. The machine does a pretty good job of delivery. Some people stated it was very clean. Well, you have to be pretty careful to not have some mess. The nice thing about this product is that it does not itch like insulation I have dealt with 25 years ago. The job of stuffing the product in the machine is a bit of work as the removal of the outer bag does require some exercise. My son and I worked on our attic from 8 a.m. till about 7:30 p.m. on a Sunday to get the job done. With an attic that is easier to get about in it would be faster. At any rate it is NOT hard to do and will pay for itself in the first year. I am good with that.

I expected an itchy mess but my son and I were surprised how easy it was to install using the free machine. We installed 40 bales in one day last month. His 1930's house had very little insulation and we noticed it was slightly quieter, though not quite as much noise reduction when we had 27 double-pane windows installed last year. The heater is cycling on much less frequently so we're expecting lower heating bills this winter.

Rated 5 out of 5 by from Easy to install I had never used a blown-in product before this. I wanted a final R value of 40. The attic had R5 and is about 2000sf. A contractor flaked and I asked a somewhat experienced friend to help me. He was in the attic and I (a chick), and my 8 year old, fed the machine. I'm not sure why but we ended up with a lot of extra bundles. When I did the math, per the atticat website, I thought that I needed 25 bundles. My friend thought we needed 40. So, I bought 35; qualified for the discounted price. We used 12 bundles to achieve R40 for 2000sf. This process took 1 to 2 hours; including set up and clean up. I set a bundle on a 5 gallon bucket, cut it in half and pushed half a bundle into the machine. Machine rental was free. I own multiple houses that needed attic insulation, so I used the extra to do two other houses. I had to rent the machine for another day for this, but knew that I had time to do two houses in a few hours. The second house's attic is about 1800sf and had an R value of about 0. It took 12.5 bundles to achieve R40; in 90 minutes. The third house is about 1500sf and had an R value of about 5. We added 9 bundles to this house in an hour. It was definitely easier to do this task with three people. A one point the clamp loosened and the machine blew insulation ALL over. I don't have proof, but I suspect that jamming the machine as full as possible creates a denser product. The two houses that I did where I didn't jam the machine full, I used fewer bundles. With the third house, I was sick of the process and kept the machine more full. I used more bundles with this house. Even if I hadn't kept the machine full with this third house, I NEVER would've used as much insulation as the math showed.

The videos showed a remote controller on the user end of the blower hose. The blower Home Depot supplied didn't have a remote. None the less, this was about the easiest home improve task I've ever done. I should have done this years ago. With my wife loading the hopper, I expected the job to take two or three hours. It took just barely an hour. It was so quick and easy. Just copy the how-to videos and you cant go wrong.

Rated 2 out of 5 by from Hidden Charges. After purchasing 10 bags of insulation you get to rent the machine for free. Try again. Home Depot does not have in their description that you are required to put a deposit of 250$. I guess management wants to surprise that bit of info. The tool guy Harry was so professional. I asked him if the battery on the remote was good and he said that I can replace it if I need to. I paid all this money and they want me to fix the machine myself. Top notch. The machine blows so fast it was more work than just doing by hand. The Home Depot Saint Cloud,fl has really gone downhill. Feels like how Scotty's was when Home Depot came in and took all there. business. Lost three stars for how the Tool Rental guy was.

Rated 5 out of 5 by from Immediate A/C improvement! We had a problem with the insulation in our attic when we bought the home. There was some old water damage and rodent problem so the insulation had to go. We needed additional insulation as well but prior to adding more we had all the old yellow stuff removed. After a few weeks of very part time prep work (cleaning every nook and cranny, installing soffit baffles, running data cables, adding a few dozen can lights, replacing old fan boxes with modern/up-to-code boxes, and a few other things) it was time to blow in the insulation. I was dreading it. Finally I decided to stick with fiberglass and I'm glad I did. Even in a cramped, raftered attic, it was fairly easy to get the hang of. The trickiest part was getting it blown into and up against the soffit baffles to the correct height. My roof pitch isn't steep so the insulation came up to nearly to the top edge of the baffles so getting enough in there without clogging the vent wasn't easy. Aside from that, blowing it in was mostly a game of patience. The best part is the huge difference it made, thermally speaking. Before we removed the old insulation, on a 95° day, the house would get up to 80° on the top floor. This was even with a lot of shade from a large elm tree on the SW corner of the house. Around the time the insulation was removed, we cut down the elm for unrelated reasons. After that and the removal of the old insulation, the top floor would get to 85° or more. The first day after the install it was 95° and the top floor never got above 72° (and that's without the shade of the elm). Huge difference! Helpful tips: - Use a 4-5' pole (attached with duct tape) to help reach into soffit areas. - When you need to lay down insulation close to you, when your finishing near the attic opening, or when you need insulation to "fall" into place, use your hand to redirect the flow to where you need it. - Mark the rafters with a black marker in more places than you'll think you need. It takes out the guess work. - Be careful where you point the hose: you might get insulation in places you don't want it and you might blow a fresh pile to pieces and have to start over (use the hand technique above). - Though the instructions advise against this, it helps the consistency of the material and flow rate if the person at the machine uses some force to push the block of insulation into the paddles. It's also helpful to load a new half block before the first one runs out. Otherwise the person in the attic has to wait and gets a stream of just air that can ruin the pile. - When you do get a stream of air only out of the hose, use it to touch up/even things out or blow insulation off rafters or anything else that doesn't need insulation on it. You'll know when a new stream of insulation is about to come out because the sound of the hose will change. - N95 respirator and glasses are a must. While not nearly as dusty as I thought it would be, there's still a fair amount that could get in your eyes and lungs. - Duct tape the hose to a rafter to prevent it from falling out of the attic. - Stick a box fan in the attic opening to keep insulation out of the house and to push some cool air into a potentially hot work space. - Bring water with you into the attic. - Use two way radios for better communication. The remote on my hose didn't work very well so turning off the machine was sometimes a matter of yelling to the person outside. - My attic is just over 1000 sq ft. 27 bags got me to R49 in 3 hours.

Rated 5 out of 5 by from Easier than expected My wife and I (65 years old) blew in 18 bags in 2.5 hours with quick breaks after each two bags in attic of a metal building, 1350 sq ft. It was easy. We didn't have communication or remote control but stopped after each two bags to chat, sip some water, and re-position the hose. The ridge is 8 feet high and I put nine inch plywood runners along each side of the attic spaced half way between center and edge which allowed crouched walking and good footing with the hose. I duct taped the two lengths of hose together with a metal sleeve between the two. One review suggested 3" pvc pipe to direct product and extend range but I found that to be somewhat cumbersome and not needed as the range from the end of the hose was about six feet so I could put product about ten feet stepping onto joists and extending the hose..Having worked in attics I had scary thoughts of being covered in insulation which didn't happen. I used safety goggles, dust mask, a ball cap and tee shirt over that, long sleeve shirt, and trousers for full coverage. I removed the goggles because they kept fogging and didn't use eye protection as the dust was much less than expected, almost none but the mask is definitely necessary. I put lights up before the job to see all areas and would highly recommend that. I had concerns about rental equipment but this system worked perfectly. Do it before the sun heats up the attic.

This insulation is 5 star and making a huge difference in my attic, keeping the cold temperature out. But I want to make it clear: when you get the machine make sure all the parts are there. We were missing the screw connection and a section of hose. The hose we did get needed to be taped together. Check the check list on the machine. It took three trips to Home Depot to get this resolved. Katy in Soquel was the only person who pushed to borrow a part from another HD. She kept me from screaming at the top of my voice about the lack of customer service.
