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 AttCat machine conditions the insulation by adding millions of tiny air pockets that give the material its insulating power & 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: R13=151.4sq.ft/R30=65.4sq.ft./R49=38.8sq.ft.
  • AttiCat insulation maintains R-value over time and provides temperature and sound control
  • Self-feeding system provides complete coverage, even around pipes, wires & outlets
  • No mess, the insulation releases and expands completely inside machine
  • Minimum 50% certified total recycled content

Rated 5.0 out of 5.0 by Go for it! It was actually fun to use! Thanks to all those who left suggestions as all were very helpful! This was so easy overall and I spent less than half of what I was quoted by professionals for the same work. I loaded 10 bags in my SUV on one trip, and the machine & hose in another trip! I HIGHLY suggest getting a headlamp as it makes things so much easier. You definitely need goggles and a good mask too (just for the dust). Also - be sure the hose has the remote attached when you pick up the machine! My first hose did not and we tried working that way (texing to start & stop) and it was just a pain. I called the store to get the remote (which already should have been there!) and that made a world of difference! So easy to control to move around the attic as needed. It blew very fast & easy, and my helper said loading bags in the machine was a breeze too. He figured it was about 10 - 15 minutes per bag (roughly). I was amazed at how much coverage I had. Using your hand as a "deflector" when needed worked too. You do have to plan how to "back up" with the hose as you go because it projects a good distance. I actually had FUN with this DIY project!

Rated 5.0 out of 5.0 by Easy as pie I'll start thanking all those of you that wrote such convincing descriptions that this could be done easily by a DIYer. I will incorporate other's advice too. You'll need a truck to transport. I bought 20 bags (1700 sq ft house for an additional 33 R) and then you need to haul the machine. One mid size suv for the machine and two accords still wasn't enough for everything. Another trip back for the remaining 5 bags. You not only have the machine, but two large trash cans of hose. I don't think a broom handle attached on the end would be nearly as effective as a 3' section of 3" pvc I duct taped on the end of the hose. I can't stress enough that that was the trick. The insulation shot out wonderfully and I could direct it perfectly. Up close, I deflected off the ceiling. Another must. A halogen light, $10-15 at HD. A long extension cord. Lights up the attic light daytime. Ideally one person to feed the machine, one person in the attic pulling back excess hose/ light extension cord and to relay info the feeder guy. Buying goods, machine "rental", two trips to HD, blowing the insulation, and return of the rental in under 4 hours. Btw, an 1850 sq ft ranch w/ the attic access on one side, the 100 ft hose was sufficient. That's it. go for it. November 17, 2013
Rated 5.0 out of 5.0 by Easy Peasy After getting a quote for $2400 from Home Depot we decided to do it ourselves. Set up, operation and cleaning the machine was a breeze. Blowing the insulation went perfectly. Once I got used to the flow I was able to spread material smoothly. $650 to do 1600 sq. feet and that included paying a neighbor kid to feed the hopper for me. The only small issue we had was the connection between the two hoses. I would suggest duct taping the connection just to be safe. Other than that 2 hours and done! Saved us tons of money.

Rated 5.0 out of 5.0 by So easy! I absolutely loved this...I bought 15 bags (rental free for 24 hours with 10 bags) for 1000sf with about 1" of existing flat and nasty existing insulation. The machine was so easy to use. Bags loaded in easily, the hose was lightweight, basically everything about it was great. The insulation ended up going further than I thought. I ended up with about 18" in most of the attic (except the center where I plan on putting plywood down). After all that I only used 9 bags! I wanted to make sure I used at least 10 and my buddy loved it so much, we shot over to his house and blew in a few bags there. I highly recommend this and wish I had done it months ago!! 9 bags x $32 = $288 CHEAP! January 18, 2013
Rated 5.0 out of 5.0 by This can be done by grand parents!!!! First of I would like to thank all the previous posters for taking the time to relate their experiences and share the tips they have found helpful. After doing some work in my attic I discovered the builder had not done a very good job of insulating the attic. It was a new house in 2011 and the stated R value was R30. There may have been some places that were R30 but there were also some R0 places. It wasn’t put down uniformly and there were some places that had absolutely no insulation. I decided I would put rolls of R30 down. After purchasing 9 15” x 25’ rolls of R30 I discovered I couldn’t get the rolls in place much less unwrap them and roll them out. After reading all the comments on the Home Depot web site my wife and I decided we would try the blown in insulation. I did all the prep work prior to the day we had decided to do the work. Mainly I made sure the vents were in place and cardboard was in place to keep the insulation in the proper area (our attic has a higher level in the center and then a lower level on each end – the cardboard was to keep the insulation for the higher levels from falling down to the lower level). I also made sure the light fixtures were Insulation Contact (IC) rated. I put down fence boards in key area to walk on. I left those in place since they were extras we had from a previous house we had owned. We purchased a section of 4” PVC as someone had recommended but didn’t wind up using it. I could get everywhere I needed with just using the hose. The Tool Rental representative was extremely helpful. She said if I needed to I could purchase 10 bales one day and get a free rental and then purchase 10 more another day. We decided we only wanted to do this one time so we purchase 25 bales of insulation and decided Saturday was “the day”. I picked up the machine this morning at 6:00 AM. At 12:30 PM we were out of insulation and I wasn’t done. We went back to Home Depot and purchased an additional 12 bales. At 3:00 PM we were returning the machine and 3 bales of insulation. All totaled we blew in 34 bales and by the insulation markers (free at Home Depot) we brought the house up to R60. We considered buying walkie-talkies but didn’t want to spend the money on something that would never be used again. We have two cordless phones and discovered we can use them as intercom so that is how we communicated. We also purchased a two-pack of the Defiant 100 lumen headlamps (I will use those again). They were great!!! Now if anyone is hesitant or doubting whether they can do this or not consider this: I am an electric engineer with no training in the building trades. My wife is an Administrative Assistant and doesn’t have any training in the building trades. Also, I am 63 years old and my wife is 68 years old. This was much easier than I ever expected but reading the comments on the Home Depot site helped a lot as did doing the prep work ahead of time. The only reason I didn’t give a 5 star rating is the remote control didn’t work. It would have been helpful. I feel if you are going to advertise something it should be fully functional. I think the key things that helped this project be a success was: 1) the comments on the Home Depot web site; 2) the advice from the tool rental manager and the sales personnel and the at Home Depot; 3) the headlamp; 4) doing the prep work ahead of time; 5) a team approach on the part of the machine operator and the hose operator; 6) the military discount at Home Depot.
