How to Insulate Your Attic | DIY Renovation

[@Whois2440]

I've used this machine before. 10 bags is ALOT of insulation. What my Lowes store told me was to buy 10 and return what I didn't use. They wouldn't charge me for the machine that way. Tip to others.

[@olwhiskers]

Good tip!

[@worldchanger23]

Oh wow!

[@Hp.dp.69b]

Used this same trick last week at home depot! Worked like a charm lol

[@BadWeatherfreak]

Exactly what I was thinking

[@mybestideas1]

Good tip! Thanks!

[@jsoko1989]

Duct tape a broomstick to the end of the hose for additional reach; it’s great for low pitch roofs. Another good thing to have is walkie-talkies to signal the loader when to start and stop the machine; you will keep your living space cleaner when the loader can be in the garage or outside.

I just did my 2000 sq ft shop this past weekend. I have a few tips that probobly have already been covered in other comments but I stopped reading after 5 minutes. 1. Buy enough bags to get the bulk price and return the ones you don't use, you will still get the bulk price. 2. If you buy 100 bags like I did, just pay for delivery, they will unload the pallets anywhere you want that the fork truck can go (in my case they went in my paint booth). 3. Don't bother with their machine if you buy cellulose. We clogged up immediately, after searching online for the instructions for that machine I found that it will void the warranty if it's not used with their insulation. 4. Insulation makes a mess! If your bread and butter is automotive paint, don't setup the machine in a paint booth thinking the ventilation fans will magically make it more comfortable for the "stuffer". You will spend an entire day cleaning. 5. Spray paint lines on truss webs at the height you want before you begin. lastly, take a nice sturdy piece of lumber up to move around on. Moving from truss to truss when spaced 48" is not fun, stepping on a loosely attached piece of lumber is also not fun when it gives out and you have 12' of distance and a .5" piece of drywall between you and a concrete floor...always be ready to grab something even if you think you are on a secure framing member.

[@Solnechnodolsk]

You need 25-3o bags.

[@TheTerminator1919]

Perfect timing for such a video! Hoping you can show a video of removing old insulation and starting fresh.

[@plawton35]

That is, exactly, what I need. My house was built in 1956, and although seller’s disclosure reads “no” for anything hazardous, I want to be safe.

[@jameslastname9171]

Tip: rent the machine and get 10 bags even if you know you only need less. Take the machine back and return unused bags.

I am a novice at DIY. I watched your video today and conquered my insulation! Thanks for making the video!

[@SpecialKthx]

OMG, you did so much stuff wrong, I do that for a living and you showed stuff that could damage homes..... first of all, shooting without visibility is wrong because you dont want insulation touching the roof because you will stop airflow from cleaning up the condensation is the winter.... also, you blocked all the airflow from the soffit when shooting..... also, please wear at least a N95 mask....

[@58leebee]

I was thinking the same thing, a recipe for moisture build-up and premature roof structure deterioration.

[@dherrington2001]

I was curious about covering soffits, but mabe bc it's an old house, perhaps it doesn't have any? I'm not a builder, but i have been studying how to do this for my house

[@TinyAcresFarmHome]

@@dherrington2001 That house most likely doesn't have any soffits. Hence why he blew it all over. Does the material stick to surfaces?

[@alexisjankowski3281]

Yeah, my house doesn’t have any soffit vents, so I won’t need to worry too much about blocking attic ventilation. But you brought up good points to consider. That made me think that adding q vapor barrier like he has it will be important!

[@SpecialKthx]

@@alexisjankowski3281 its all depends on the climate you live in, if you live in cold climate you dont want the isolation to touch the wood surface of the roof even if you dont have soffit, the vapor barrier is critical in cold climate in the inner part of the house, while in hot climate you want it in the outside

[@mason395]

As an HVAC installer and have spent lots of time in attics with this stuff please... please.... please consider completing any and all electrical/HVAC projects BEFORE you blow this crap in your attic. Contractors will charge you more for having to deal with installing anything in this nightmare.

[@heidikagarakis8102]

We did this a year ago and it came from HD without directions. I’ve got to show my husband, we fed it so poorly and had the hose in backwards. Can’t stop laughing

[@lylecoglianese1645]

@Heidi Kagarakis, hey... You learned a lot. Now you can help others do it right. A great experience and some good laughs. Bonus, you got to spend time with your husband 😉

[@TheMitchyevans]

Can you combine this with already-blown cellulose-based insulation from the 80s?

[@JSLEnterprises]

your 80's celulose, like mine, is probably that grey stuff... its also probably not even cellulose. Nothing was probably sealed when it was blown in either. It would be better if you vac'd all the old stuff out, foam sealed all the gaps, and then blew in new stuff.

[@Shadi2]

big box stores will give you a free 1 day rental with the purchase of a certain number of bags of insulation. I strongly suggest buying cheap long sleeved coveralls. You'll get a lot less itchy and can just toss them rather than clog your washer with fiberglass/cellulose.

[@chriskhall]

I'm all into doing this but all the videos I've seen so far say I have to do sealing and baffles...any thoughts on that?

[@NSW1990]

Hey Jeff, any recommendations with attics that have soffits? Do you recommend those soffit vents that hold the insulation, so it won't fall into the soffit?

[@GODZILLA1521]

Hey.. boys good job, just a fyi the machine party has a cutter on the inside for the bags. Then I did my attic 2 months ago, it was hot!! We blew in 30 bags.. at each 10 bag interval I took a 15 min break. I had to do 24 inch for the R60. We also dead in remote. I had to call tell him to stop sometimes he couldn't hear the phone. DYI Tip: Instead of blowing insulation straight up, you could just cup your hand over the nozzle or stop piece of cardboard. Cheers thanks for your videos

[@scottmcphee7730]

I was planning on doing this at the end of the month for the first time, and I was scared that I would mess it up. Thanks Jeff, for easing my worries!

[@garyglenn3654]

My wife, son and I did this years ago with cellulose. No directions on the machine. We used 18 bags. I was in ceiling, my son was managing the hose up to me and my wife was feeding the machine. We worked non stop until done. When finished I came down out of the rafters and died laughing. My wife was completely COVERED in cellulose! I asked her why she did not say something as we worked. She said she wanted to but realized we were making such good progress she did not want to slow us down. Glad she had a mask on! To anyone considering doing this, DO IT. Made a big difference inside the house.

[@TheErms12345]

[@allent555]

Will definitely do my own after seeing this video. Can you show the removal technique for existing blown insulation sometime, please?

[@1Akanan1]

You have to use one of those huge vaccum that restoration company have. Youll also need a truck preferably with close box like the uHaul ones. Talk to your landfill before to show up there with it, they all have different rules and preferances with this kind of stuff.

[@sandrabulluck1896]

John L - good advice!

[@ginacirelli1581]

I think I'd probably pay someone to take the old stuff out and then at least save some money by putting in the new stuff myself.

[@deirdrevi7640]

[@fabiantorres9621]

Great video. I did notice you didn't talk about electric power lines and lighting fixtures. Do I need to worry about covering them up?

[@binomial]

I did this about 8 months ago. Lowes had an amazing deal on blow-in cellulose. They were selling 100 bags for about $550. The total R value is way overkill, but 100 bags was cheaper than 70 at the time. You definitely want a high quality respirator and a very bright light. It took about 6 hrs to fill a 1200 sq ft attic to a depth of 2 ft. It is really important to make sure you don't block the soffit vents if your attic is vented. You can use rafter vents which extend the soffit vents. They cost about $1 each. If you want to get the best value out of the insulation take the time to seal all the gaps before insulating. It's a lot of additional work, but about half of the energy loss for a typical old house is convective rather than conductive. Sealing the gaps in the attic will go a long ways to reducing the convection loss. GreatStuff Pro is a good choice for filling the gaps.

[@ChadAmI80]

That is a heck of deal! How long are the soffit vent extensions? Do they just go up the roof rafter bay above the height of the insulation?

[@JuanPerez-lt8iv]

Could you make a video on how to blow in insulation to existing wall. Thanks

[@saliston]

We just bought a newer house. The area over the garage isn't insulated. This will be my first project.

[@ChadAmI80]

This is also on my list for next year. We just bought our house this year. The garage is going to be my workshop and I want to heat and air condition it, but I live in Pittsburgh. All of that heat and cooling is just going to go right out of the roof LOL. Good luck with your project :)

[@mykalp2329]

It’s a new house why not tell the builder to come back and finish the job?

[@koryleach9660]

Ensure you put in the ventilation chutes and some fiberglass blocking at the outside top plates to keep from blowing into the soffits! Also foam/ caulk around the junction boxes to ensure that the ceiling is air tight before blowing in the insulation.

[@DMUSA536]

Love how you show your mistakes. We’re all human

[@daleogle3620]

I don't remember hearing you address soffets when blowing in the insulation. It is extremely important to not block them with insulation especially in hot humid climates.

[@fluffEfoxProductions]

He didn’t address them because his roof doesn’t have soffets... he mentions his house doesn’t have soffets in the “roofing” video on his farmhouse

[@goodrabbi7176]

[@thertc204]

This video might finally convince my father that it's worth it for me to do it myself instead of hiring someone!

[@Olivier11986]

If we have a bathroom fan in the attic, should we put a vapor barrier (plastic) on top of it before insulating like this? Love your videos btw, keep up the good work!

[@amandasue6500]

This is much more expensive in the US. We looked into doing this to our attic, around $800 not including the machine rental fee.

[@_Mikekkk]

I have such insulation in my attic - it's a mess. I would prefer other option - foam sprayed between studs, it expands and sticks to the roof and you have clean attic. Why not to do that?

[@twestgard2]

Jeff’s emotional presentation always seems like he’s already explained everything to six other beginner level classes in the same day, and he’s trying REALLY HARD to maintain his enthusiasm level

[@adrianneagu2619]

Hi Jeff! Your videos are a tremendous source of valuable information to the DIY community. Thank you! Related to the topic of attic blow insulation: may I recommend that you post a video showing how to create a walkable attic over that blown insulation? The particular case I have in mind is that of new homes (in US) where the roof support structure, as well as long trusses over rooms/garage seem to use "skinnier" lumber than the standard 2x4 and, more, they connect all over the place using Simpson's mending plates. All that seems to me quite flimsy, and one would need to build some good support structure tied in to the roof rafters for a tentative walkable attic floor. There are very few postings on the topic, and your contribution to illuminating it is very much appreciated.

[@michaelgoldsmith635]

Is putting plywood down in attics to create storage space/ safe spaces to walk not a thing anymore? Also, if you later need to put in can lights into the ceilings below the attic, how do you maneuver through all of that to clear out where the cans go and not end up falling through the ceiling because you can't see the joists?

[@guitarchitectural]

We really need to insulate our attic (100yr old house) but I would like to put pot lights in our bedroom and wire in some kids room cameras too, both of which would require attic access. Is that possible after blowing in or is there another route we should go? Or is it still possible to do those things with an attic full of blown insulation?

[@michaelrehmancerppws6501]

Do you think blowing in fiberglass or cellulose is better, what ever you think I will do, when I rented the Machine it had a hole in the hose, our attic is long, so we didn’t now until we got to the spot.

[@cerebro1231]

I had my attic sealed and insulated with open cell spray foam. It was very expensive but worth it in my opinion. Central Air conditioning run time has been cut in half from 10 hours a day of run time to now only 5 hours.

@@bigbeef8935 I got a quote similar to yours! I will vacuum out all my insulation and seal my attic then blow in cellulose.

[@TinManKustoms]

Done it quite a few times. One way of getting the right amount of insulation in is use the flags like the construction guys use to mark gas lines and power lines. All you have to do is staple them to the sides of the truss for the first few trusses this will help establish the right height.Two way radios are very helpful for communicating and install rafter vents so your soffits can still breath if they are the vented type.

[@absolutemalmaute9592]

R-20 would be super insulated in Australia... then I realised you have a different R-Value System. Great vid.

[@apf20]

Great videos on your channel. We used this machine to insulate both our attic and inside the walls of our 1937 Sears home. Owens corning has a video on how to fill the walls, I had to drill a lot of 3" holes and then patch them, but our heating bill was cut in half the following winter. You could also insulate from outside by removing and replacing your siding, which was not an option in our old house. TIP - I did the attic and the walls on separate days. So I bought 20 bags of insulation, had the cashier ring up 10 at a time and got two receipts = two free machine rentals.

[@EWC88]

What’s your recommendation on insulating rim joist? I have batt in there currently that’s all messed up so I was going replace. I was going to do 2” XPS foam caulked and then spray foam around it to fully seal. Thoughts?

I have an attic with cellulose insulation that was blown in probably in the mid-70s. We did have a roof issue that allowed water to penetrate the attic in a few spots. Now that the roof issues are fixed, I would like to add insulation. Would it be OK to blow new stuff over the old stuff. It would seem that it wouldn't make too much of a difference. I don't think the pink stuff would compress the existing cellulose, but that's why I asking. Any thoughts or ideas would be appreciated

[@5620103893]

Its fine to add the new insulation over the old. However, removing the old insulation first gives you the best chance to easily seal any air leaks into your attic that you'd otherwise miss. Its really how much you value your time vs how much you'd save. Personally, I'd just apply the new over the old. I can't stand being in the attic a single minute longer than neccessary.

I work for an insulation company and we add new over the old on a daily basis. We just call it a top up!

[@matthewfunk6658]

@@BloodyNigerian If the rafters are too small to work in for blow in then it would have to be batted. That would require doing from below. We use friction fit batts that will hold in place. After that we poly and then the drywall goes up.

[@keelylowry6674]

So I bought a pretty old house, and I need to reinsulate the attic. Do I try and get rid of the old stuff? Or just blow in new stuff on top?

[@TheCrookHook]

I did this with cellulose at my place. I had R5 value in the attic and recieve a government grant from Quebec to insulate. I had to put cardboard baffles to keep the ventilation from the soffits to the attic. The machine I rented was similar but unfortunately it was beaten up pretty badly. It sounded awful due to the bearings being shot. Since the bearings were shot, it seemed as if it was forcing to turn; which would result in a slower output inside the tube and... You guessed it; clogged the tube up! This part was a nightmare as I had to come back out from the end of my house and start unclogging this monstrosity in the driveway. In any case, the hardest part out of all of that was to install the baffles (no room and your face is real close to mouse crap). Rest was a piece of cake even though the machine needed some maintenance. Oh and that grant I received... I actually made 400$ to insulate my own place up to R50!!

[@handytbutler7380]

Hey Jeff I have used that on alot of jobs and it works great. One thing to point out is that if they are blowing into their attics , be very aware of the soffits, they way you showed it it looked like you covered the soffits which will stop the airflow into the attic and out the roof vent. You know as well as i do that if thats not explained correctly some fool will blow it all over his vents and cause a ton of damage down the road... keep up the videos, i catch a thing or two from you ever so often. that comes in handy....

[@MrHuberb]

Hey handyt butler, How do you keep it from going in your soffits? I would like to put more insulation in attic but I am afraid that I will close up my soffits. Thanks

[@handytbutler7380]

@@MrHuberb one way to do it is use a piece of luan and a small board to nail it to so you can hold that out and keep it from going into the soffits... i use a paint guard for spray guns also just to keep it from flowing in... if it does go in usually you can get something to pull it back out...

[@daisyl12]

Use baffle vents. They can be made of cardboard, plastic or thin styrofoam that you can pick up at Home Depot (Owen Corning has pink ones) or other such places. You slide them in toward soffit and between the rafters and leave them there. They have a channel in them to allow the flow of air. You then surround the outside of them with insulation. The baffle should be higher than the amount of insulation you put on the outside of it so you don't get insulation falling into the open channel.

My grandfather was an electrician and we still have his old hopper for blowing insulation. He used to do walls in existing house too. He had an attachment for the hose that was a 1-inch nozzle. You'd drill a hole about a foot down on the wall and foot or two up from the bottom. Stick that nozzle in and let it rip. Then you plug the hole with a one-inch dowel. Usually we worked on the exterior but there were times we had to work from the interior. It's a lot of holes to drill and plug. Not hard at all but tedious. Attics in the summer were a bear though, if you were the guy manning the hose. Next time I'm at my folks, I'll take a picture of the hopper and send it to you. It belongs in a museum.

If I don't have soffit vents do I need to install rafter baffles?

I have a ridge line vent and gable vents and I don't think I will ever install soffit vents. Anyone have an answer?

Do they make a machine to suck out the old insulation? I've got their styrofoam bead like insulation and I want it gone.

Yes pending on where you live rental places have them but you may have to contact a insulation company to come do the removal.

Shouldnt you install foam batting on the ends for the ventilation of th soffits?

[@jasonbengel]

I did this last year with cellulose on top of existing but insufficient fiberglass bats. The dust level was far more insane, but I felt like cellulose with borax could reduce bugs (and it did!). AC ran at least 50% less. I used radiant foil to block off the soffits, but considering the dust from the cellulose, the radiant foil probably has little value😾. Loved the pink Xmas, had my family thinking back to our insulation party.

[@jackswiatek5221]

What about proper ventilation of the attic? As I understand gaps near the walls have to be maintained for the roof to have proper ventilation - at least where I live (FL). And blowing insulation inside may clog this space. So any tricks how to do it without crawling all along the attic?

[@BadWeatherfreak]

[@Ty-Is-Tired]

Would you recommend using a radiant barrier in the attic along the top 2x6 rafters or putting more of the pink insulation up there? The goal is to keep the attic cooler in the summers

What great information for doing it yourself. But my question is, my house was built in 1955 in North Jersey USA. I have a A-frame attic, the insulation up there is a one roll layer between the beams, and it's a mess of the old fiberglass insulation. So I guess the best way for me to do this is to get rid of the old insulation and do something like you did for better insulation, the Attic is R 49 to R 60 in my area, so it can be right. Also I have pop out lights in the ceiling and a light exhaust fan in the bathroom should they be covered?

Are there any issues with moisture blowing it on top of BAT insulation? I have a very tight attic with about 10 inches of BAT and need to add more insulation. I was looking into using blow-in. Great video!

[@marriedGary]

My attic is fine as far as I can tell but after watching this video I kind of want to do it just for fun!

[@dabidoe]

this guy on the right looks very comfortable on camera

[@asawoszc]

Can you comment on the use/need for baffles in the attic? Didn't see this mentioned in the video.

[@SpecialKthx]

cause hes bad and he did the opposite, he blocked the ventilation in his attic for no reason.... the baffles are okay if you think you might block your soffit ventilation, if you think you can shoot it without the baffle then its okay, if you are doing cellulose you should put those because cellulose is harder to shoot because it makes way more dust

[@juantransportador]

HELLO from chihuahua mexico, we just finished putting the shingles in the roof, we have a roof for the next 30 years, do you recommend is the best time for putting more insulation? GOD BLESS YOU AND YOUR FAMILY.

[@williwonti]

The best time to insulate your home is 'as soon as you can'. The money you save really adds up over time.

[@HomeRenoVisionDIY]

Yes I do!Cheers!

[@juantransportador]

Thank you

[@dylanshabtai4554]

How can confirm that you hit the far spots by the rafters joists?

[@NonaPepper]

Your timing is great -- we're getting ready to insulate the attic in a couple of weeks! One question -- is it ok to use this type of insulation in the walls? Just cut a hole in the drywall between the studs and blow the insulation in? We have a house built in 1970 that doesn't have enough insulation.

[@sandrabulluck1896]

-Good question Nancy! Hope you get an answer!

[@lisakukla459]

I'm also very interested to know this.

[@rockymntain]

Use a stud finder and locate your studs in the room. Drill 5 inch holes about halfway up the wall in between the studs. Then push the hose to the top of the cavity and let it fill wall from the bottom up as it drifts down into the lower part of cavity. You'll know it is getting full as the insulation/air pump will start to bog down. When it appears that the wall is full, start to slowly pull the hose out and allow the space where the hosed went to fill as as it is pulled out. Takes a little practice but you'll get the technique down after doing it a few times.

[@lisakukla459]

@@rockymntain This is brilliant. I would've gone in at the top, but now I can picture exactly how that could leave a gap.

[@gustavobarbieriperei]

Is it possible to blow that in a Cathedral / Vault old house?

[@martinpantoja2423]

i understand your thing about safety and protection but would in this case it not have benefited you to have those earpro headsets that you can talk to each other through? used to use them in the army when working under certain trucks and they worked wonders at bringing down the outside noise level while letting us communicate with anyone in the drivers seat in case anything crazy happened while were inspecting.

[@frankierodriguez4782]

I would like to see his son put something together or install something. He must know plenty.

[@paulsecondi2053]

Nice job, was thinking about improving my insulation from the builder. 15 year old home in Atlanta...

[@MrNorthstar50]

Good video here in Texas we nail little markers around in attic so we have know how to maintain the depth of insulation we want, they have an inch scale on the markers.

[@ThePositron2]

Yep, although watch out! One of my coworkers had his attic insulated and on a whim he pulled up one of the rulers they nailed down and the bottom two inches were cut off!

[@Bigshoots86]

id be pretty offended if you didn't have an extension cord

[@lookwhativegot9824]

I have an old home and was thinking about doing this in the attic to increase the R value. My one concern, however, is the lack of a vapour barrier. Do you have any suggestions for dealing with a plaster and lath ceiling with no barrier?

[@David-vn7th]

Another great video, thanks! I have an insulation question. I am contemplating insulating the space above my 3 car unheated attached garage. The attic space over the home space is well-insulated (blown) when house was built 6 years ago. I noticed that there are black pvc/plastic inserts(about 2" long) between the studs extending down to and sealing the vented soffit area. The blown insulation covers the insert except of course the attic end which is open. I am assuming these allow for air to flow from the vented soffit into the attic. My question, finally, is: should I install these vents in the garage? Garage has vented soffits. I do have one gable end ventilation grill, numerous roof top non-powered vents, and one Broan 356BK1600 CFM Roof Mount Powered Attic Ventilator, Black PVC Dome. which really seems to help with this Texas heat. Thank you for your help.

[@HomeRenoVisionDIY]

insulating the space above the garage will help to keep it cool. to avoid filling in the soffit air flow use rigid polystyrene rafter vents from Owens Corning and then blow in the insul. Cheers!

[@davidrobards9587]

Jeff can you do one for a bonus room over garage and doing finished ceiling over it. I have what looks like R 19 on in bonus floor joists and R 19 in ceiling. Also crawl space needs some under 1st floor. Thanks

[@WarpingAround]

You had me at, "even if you can't see what you're doin' " 🤛

[@4philipp]

Is it something I could do or feel confident doing? Yes. Is it something I want to do? No I know for a renovation or touch up project you are limited which options to use. My preferred method of insulation is a continuous building envelop or rigid foam insulation (EPS or the like).

[@Caligirl0965]

I am definitely going to try doing this. Our 1920 farmhouse has NO insulation in the attic at all. Thanks for doing this one.

[@joeybrisson8097]

did it myself 2 years ago. Was the easiest job I've tackled since i bought my house. Anyone can do it paying someone to do it is a waste of money, unless you don't want to get dirty.

[@manusamoaus]

Not only can I do this myself after watching this video, I NEED to do this to my attic. Thanks for showing how simple it is.

[@maximeturgeon]

Hi Jeff! Great video again. In my roof my rafters are only 4 inch. What can I do to get more r value aside from taking space in the house? It's a 1 ½ story Canadian house
