Insulating Finished Walls

- I love doing projects in the garage. Unfortunately, working in an oven while recording is tough. I can’t run fans so I am trying to make my garage a bit more livable before going to the expense of adding AC. So in this video I’m opening up my walls and blowing in cellulose insulation into a dense pack.

1 year later and I'm still happy I did it! ua-cam.com/users/shortsoRefsKMKpY0
Where did you got the blowing machine ?
@@khanmuhammad5244I rented it at Home Depot. It’s free for 24hours if you buy enough insulation.
Just a thought - maybe cut one long skinny rectangle across the top of all the studs. That way you don't have to deal with using that drill bit so many times and patch all those circular holes. Should be much easier to tape as well.
This is a good thought. One or multiple long sheets would have been easier to repair. Though I've seen this process done multiple times and it's always with the round holes. I'm just a goof ball in my garage so I'm not sure of the merit of doing it this way. If I buy another house that needs insulation I'll certainly try your way!
It should be code that all garages are insulated and finished the same as the interior rooms.
That would be awesome. But for that vast majority of people would have no, or little impact on usability. In my area, it is nice that garages are finished and primed vs open studs like many places in the country.
That would put insulation companies out of business 😂
Thanks for the video! I’ve done everything from concrete to electrical but I’ve never done this before so it gives me a good idea what to expect.
Outstanding. It was a LOT of work, but not that difficult. The drywall finishing is the hardest part. It's such a skilled art.
I thought about doing this, but I found a company that foam filled my walls for around 2k. Not bad considering the labor in doing it this way.
@@dfoster7001 That's a fantastic deal. Nice!
Appreciate this video. I've got 3 bays, 12ft ceiling, with no insulation above or in the two outside walls. Hits about 110 F in my Georgia summers. My last house, with room above and insulated walls in 2.5 bay garage would get cold with just a small window AC. But the ceiling was too low for the lift! I need to insulate at this new house and have been debating DIY vs hiring, and fiberglass vs foam. Good to see you could get dense pack without special equipment. All that dust tho!
The dust is real. I’m still finding little fluffs around the shop. lol. But with just my swamp cooler right now I can have the RV door open and keep it 15* below the outside temp pretty easy. Good luck with whatever route you choose.
You can get a 24,000 btu mini split for $1,200. Get two and you’d be more than golden. I did that on my 2,000 sq ft warehouse that didn’t have insulation and worked great.
I keep bouncing around this idea. The heat here is brutal.
Love my Milwaukee stuff! Buy around Black Friday/Christmas. Lots of good deals.
Thanks for video, I am going to do this to my garage as well
Good info. The insulation is working well.
@@DrivingForwardBuilds trying to decide if I want to tackle(fully capable) or just pay someone and not mess with it....
@@naturalsr405 that's a battle. This was a ton of labor. Probably 80% of the cost will be labor. Really depends on where your time is more valuable.
@@DrivingForwardBuilds most definitely. Being my garage is not huge, it probably would take someone who does it all the time, about a 10th of the time it would take me. I would have the ability to slack off and have it take away longer than it needs to too lol
Future refrence i'm in Utah but just looked up places in phoenix that sells insulation by the pallot for 10x cheaper than the homedepot every state has a direct insulation buyer
Dang 10x. Willing to share the name of the place you found?
Jason! My first vid of yours! I was trying to find this exact type of video since I am going to tackle blown insulation as well. I am building an 8’ x 12’ office in my garage for working from home / gaming. I have 3 kids so (as much as I adore them) it will help to be fully separated when needed to focus on work.
I am insulating a 12’ long and 8’ exterior walls, since the office is on an exterior corner of the garage. I will also blow the ceiling of the room as well as the new walls that I am currently framing.
All walls are about 9’ high - and I need 96 sq ft of R30+ like you did in the ceiling.. I agree that all calculators seem to spit out different results… think 10 bags is sufficient?
LOVE to see that A) you respond to everyone and B) your insulation is working well! I am putting in a 9,000 BTU Pioneer split in the office as well - excited for that project. This is hands down my largest home improvement undertaking. Leaving a space for a parked car in case the next buyer of this home desires to park a car in the garage (we don’t for space reasons). Your video has greatly encouraged me to do a good job & I also watched the 3 strategies to blow insulation, going to go for the deep-pack method like you seemingly did. Though I kind of want to try the hole halfway down the wall instead of at the top, not sure. Thanks Jason!!

(PS, also in Phoenix! So, a good insulation job is more important than straight walls, level floors, or a good paint color ha!! Flip gets HOT here!!!!!!)
10 Bags may work. It will depend on if you are 2x4 or 2x6. Not sure what your transport looks like but the bags are actually a decent size. I personally would buy 3-4 more than are needed and if you have extra blow it into the attic. The other variable will be how dense you pack it into the wall. I thought about opening the wall up in the middle but was concerned gravity would take over and I might not get the pack to blow up the wall properly, especially considering I had never done it and the power/reliability of the rental was unknown. One really good comment I had was from an installer who mentioned cutting across the wall in full-sheet rectangles (like 3-4" tall). That way you could more easily fix the drywall without round holes. Or in your case if you are putting up walls to create the room there may be a way to save on some of the repair work this way. Sounds like a great project to take on. :-) The mini-split will come in handy. I've noticed through winter the garage cooled and has stayed cool. I haven't budgeted for AC yet. I'm sure I'll regret that in the next few months.
Copy that! Good suggestions. Thank you for the reply - I will check if I have 2x4 or 2x6 exterior, good point. I can always return what I don't need if I buy extra! Yeah good luck with the A/C situation - that is a fairly large space.@@DrivingForwardBuilds
This is exactly my situation. Mini split was put in today and we discovered our builder did not insulate the wall all the way down the wall as we expected. Now I need to insulate the one 20’ long wall so my mini split won’t work as hard. I want to cut holes and dump cellulose in. Hopefully it works easy enough.
you need solar mini split
Okay, so I’ve been through this, not the dense packing but the renting that pos green box, some Home Depot’s will have a krendle cellulose machine, it’s blue, it’s way better than the green one. I was lucky enough to find someone local who had a badass machine you could load 4-5 cellulose bales into and we did a 3k sq foot attic with r60 in about 4 hours
That would have been so nice to be able to load more into the machine at once.
Just wondering if it would be easier to cut rectangular sections out of the drywall between the studs and slide wall batts down?
I don't think so. In the wall you have many different protrusions like nails, screws, wires, pipes and even small splinters of wood that will catch on the wall bats and make it very difficult to slide them in. Possible yes, easier, not likely.
No. There are way to many obsticles in the wall. Even just the small splinters would catch on the bats and make it very difficult to slide down.
Thanks for your reply, yeah I think you’re right. With batts they say not to jam them in too hard so they are able to fluff unrestricted because it’s the trapped air in the batt that aids in the insulation. I’ve seen thermal imaging of batts where it’s been shown that whenever the batts have been compressed and not cut out properly to make room for obstructions, the effectiveness of the batts are significantly reduced. Why is the blow in stuff different and recommend to compact fill the void? Wouldn’t compact filling reduce the amount of trapped air thus reducing the efficiency?
@@carmeloxuereb8733 I'm not totally sure why they call for "dense" packing the cellulose. But the R-value goes up as it's packed tighter. From what I've read the r-value increases by 1/2 point from R3.5 to R4 per inch. Not having air space also helps to stop fire propagation. If packed in tight enough it can also be used as an air sealer, though I wouldn't omit any vapor barriers because I was using cellulose.
😮wowza! That’s a big job! Could you have just done below the fire block?
Yeah. But then I would leave hot spots in the wall where there wasn't insulation. That would defeat the purpose of the job.
@@DrivingForwardBuilds that makes sense. Good job 👍🏻
i might just cut a strip of drywall along the top and then cap it with a frieze board style "accent"
That’s a pretty slick idea.
Great video. Looking to insulate the ceilings in the garage. Have two bedrooms over it and the rooms get crazy hot during the summer. Any concerns with the insulation around power sockets? I suppose in theory but want to be conscious of risks.
The insulation itself shouldn't have a problem around outlet boxes. I filled the walls around my outlets. Light housings should be IC (insulation contact) rated by UL. If you have any concerns though I would consult an insulation specialist or the manufacturer of the insulation. They would be able to guide you on the risks.
Great video. Who do you use to rent the blower?
We rented the blower at Home Depot. It’s free if you buy enough insulation. And……if you happen to buy just enough to get it free, then not need all the insulation you can take the “extra” back and you still got the rental.
i had some if this done in one of my rooms and they cut out a big square in the wall along with many holes similar to holes you drilled. but i see you didn't cut the big square in the wall. is that normal what they did in my home or no
So you don't mention where the other square hole was in relation to the round one. I have seen this done with one hole at the top and another somewhere in the run for venting. You place window screen over the second hole and allow the air out. It's possible that's what happened.
1580 sq ft is the size of my house 😮😮
I do feel fortunate to have worked up to this house. Thanks for watching!
How dud it help with temperature?
On average it’s about 15* cooler than outside. Before insulating the inside would heat soak so much it would 5* or more hotter than outside.
How are the summer temps in the garage without any AC blowing after the insulation?
Not gonna lie. It was still stupid hot. But for reference on the hottest days 120+ it was hotter in the garage. After the insulation it stays in the upper 90s/low 100’s. With my swamp cooler running I can still work.
Thanks. I'm planning on insulating my walls and the half attic above my garage, but not installing AC. Just want to make sure there is a reasonable benefit
In my opinion it was worth it. Being new to Az it was hard to get used to working in those temps.
Just use a Makita drywall saw and cut a strip out of the top. Just stay about two inches from ceiling if drywall is taped.
Milwaukee. That's all
They are nice for sure.
You live in snohomish?!
Used too. In Phoenix now.
@@DrivingForwardBuilds sorry, I missed that. I live in machias. Snohomish address. Small world.
Unbelievable cheap home builders
I’m not sure that’s it. Do the garages where you live have insulation in the walls not connected to the living space? I’ve been in Real Estate 13 years and that’s the case everywhere I’ve been. It’s an option as a consumer to add that insulation at build out typically. The folks that built my house didn’t work in the garage like I do so they didn’t care.
No one in south is insulating their garage stud walls, I’m about to do mine but luckily I have like 1/5 the amount of wall space to insulate compared to video.
Lowes sale mini splits DIY😅
That’s a good idea. They were on sale recently but funds weren’t ready for a purchase. Perhaps in the future.
You should spend more time on your research, rather than you UA-cam video 😅
What did I miss?
