- In today's video I will show how to insulate a ceiling in a basement or crawlspace area using faced or unfaced insulation, and also talk about using foamboard insulation on the rim joist boards.
Insulating this area is not always required, but it can increase your home's efficiency, and possibly lower your energy bills. Used R30 insulation & 2" foam board from Menards to complete this job.

Been looking at insulation videos all day. This is by far the best one. Thanks
This is the most dangerous kind of youtube video. It makes a project look so easy that I could do it. Which means I'm going to try. And then I'm going to work on it for several days, do a poor job of it, get angry, and then swear to never do it again.
But the video did make it look super easy. So I'm going to try anyway!
(Seriously - thanks for the very informative video!)
You can do it!
You can do it! The hardest part would probably be just cutting the foam pieces for the ends of each joist space for the rim joist barrier. Everything else should be fairly easy and straight forward. Good luck!
I am a 68 year old female and used Rockwool and had absolutely no problem doing it. I like Rockwool because it is a fire deterrent and resists mold. A little more expensive but worth all the effort. I live in a very cold climate and this helped my main floor area to stay warmer longer.
I did a bunch of insulation and used an electric knife. Cutting foam board is easy, just be patient and use a sharp knife. Pushing into the foam so it doesn’t make a smooth cut means your pushing too hard.
@@monicaambs It also is easier to cut and fit.
Instructions simple. Great “show & tell” instructions. Just what I was looking for.
Explained so simply. This really is a project someone can do.
Brother man, thank you for this video. So simple, so thurough and so easy to follow along. I'm planning on insulating my basement and NEEDED this video to help me get a starting point. Instant subscribe
Do u think i can do this, to my crawlspace?
Very well done video. And you don't talk 168 mph as do many RUclipsrs. Thanks for giving a home repair dummy like me the confidence to do the job.
Instead of using a utility knife, go to the kitchen and grab the serrated bread knife that never gets used. Cuts insulation GREAT
That is the best explanation with a solution to limited ceiling heighth for a tall guy that wants to watch news and sports w/o making my wife angry. Thanks, now she will have to make something to be angry, just bring it.
This is a MUUUUCH better video on this particular topic than many, may others.
Thanks for using knauf/guardian! I work at the wv plant! It’s awesome to see our insulation installed! ❤
Thank you for this thorough explanation. You really cover all the steps.
Thank you! Rats went at my plumbing in my new build log cabin. I am saving a bundle by doing all the pex piping and insulation replacement on my own, and it's thanks to you!
Thank you brother, you have given me the confidence I needed to tackle this project. I gotta say...your excellent, straightforward delivery put me in a good mood with this whole thing too. Cheers!
You friend are underrated. Your clear, calm thorough explanation of what you are doing is fantastic.
Keep making content.
Thanks!
Thank you
Very clear calculations to follow. Thanks.
Thank you. Bought a house last year, and the owner who previously lived there made it so hazardous that it probably (helped) kill her. Now me and my wife are planning on kids. We stripped and disinfected everything possible in the unfinished basement, scrubbed every inch of it to hell with the right solutions, kept up a dehumidifier all summer, but a mold smell still lingers.
It's now so obvious, but the insulation covering the top of the walls on the side of the ceiling have the papers sticking out. Annoying, but will have to take everything out of the basement, rip it up in a hazmat suit because it's guaranteed to have asbestos, then I will do exactly this video.
We're not going to be able to have a finished basement, but this will be good enough for now.
Again thank you!
It sucks when there is no one to show you these things, now I'm disgusted that home development isn't a lengthy school requirenment. It's about needs and keeping your family safe.
Excellent and thorough video! thanks very much for putting this together.
Best video I've seen. Clear & concise, with lots of rich information and clear video.
I just bought a house, and temperatures recently reached -10 degrees F outside. Water pipes froze!, Furnace couldn't keep up! My floors are FREEZING cold!
Went into the crawl-space to heat wrap my pipes, and although I have water now, the floor is horribly insulated! Spotty insulation tacked with wood screws & boards! Insulation is essentially crushed, creating no insulated airspace under the floor. I need to re-do the whole thing, but I want to do it right so I never have to go back down there again (probably have to anyway, to tackle the dirt floor next.)
Just remember you should be using different insulation if its a vented crawlspace.
Be careful, if you insulate your floor, you will be cutting off some heat to the water pipes and they may freeze at temperatures higher than -10 in the future. You may want to concentrate on the rim joists.
This was a great video! Wish more how to videos were this well done!
Thanks man
@@D.I.Y._All-in-One my house isn't like that at the ends of the joists , I have to leave a gap for air to ventilate up the walls which are lathe and plaster , we can't get cavity wall insulation and is built for coal fires can I just put the insulation to the end of the t&g flooring which will allow air from vents to go around the whole outer walls of house , yes the house is bloody freezing in winter , is the new eco stuff made from recycled plastic any good as fibreglass is no good for asthmatics or would sheep's wool be better? , any info would be grateful from anyone
Excellent video for a home repair dummy like me. I can do this. Thank you.
Thank u for explaining which way the paper faces
Good video. A couple tips. When adding XPS to rim joist, cut it a tad smaller then you'll have a gap to Foam in giving a better seal. You may need to add some construction adhesive to prevent it from moving around.
Lastly, while compressing insulation does decrease rated R-Value the R-Value per inch increases. For example if you put R-19 in a 2x4 wall you will get a higher R-Value than R-13 (which is meant for 2x4 wall). There are tables you can look up to figure out what the end R-Value is after compression.
This was very informative, i feel i can do this myself , thank you so much.
Thanks for such detailed explanation.
Great video and very well explained, the how and why, keep it up!
Fantastic video. Thanks so much. O now feel confident doing it myself.
Thank you for this info. I have a 1980's balloon house framing and originally they used crisscross wire and nail to secure all the insulation, which would be a pain to replace, but the joists (4"×6"×8') are not anything I see in any video. Your nylon strapping and staples will make my life much easier seeing as I have to replace the insulation after getting under the house bug sprayed. Although I'm not sure what to do about the squishing of the insulation... considering the joist size. Thanks again.
I use 2" of polystyrene sealed with foam and then 5.5" mineral/Rockwool. This made a huge difference.
Thanks! Great vid. Thurough!
Good job with your video and I see you’re saving big money😉….
Thank You! Nice Video.
Loved the tips
Awesome work. Thanks
Thanks for the video
Wow! Very well done!
Glad you liked it!
Excelente video 👍 👏 👌🏻
And I like to install Tyvek onto the bottom of the joist. Unless you are installing drywall/sheet-rock.
Great job and clear explanation. How in the world can you work with gloves on? Really difficult for me to do. Better than the irritation though.
Should you leave a gap between the insulation and the floor above, or push up directly to the subfloor ?
I have a cabin in the mountains, with a plywood crawlspace wall and dirt floor. I used batt fiberglass insulation and then covered the entire crawlspace ceiling with 1/4" plywood. The mice set up a colony in my insulation and had free run of the entire ceiling. Because the crawlspace is never below 45F, while the cabin can be well below freezing when unoccupied, I'm considering going without any insulation, in order to have fewer mice and maybe take advantage of the warmth from the earth. Too bad the humidity is 80%. I tell everyone if you are building in the woods, HAVE A MASONRY BASEMENT OR CRAWLSPACE. You'll have fewer mice, rats, snakes, spiders, crickets, daddy long legs; and less mold and humidity. What I would give to have known this 30 years ago.
Daddy long legs are your pest control, they kill the unwanted insects and venomous spiders like black widows.
Plant mint around your foundation, mice and rats hate mint.
Never heard of faced insulation toward the floor. My old house had the face outward and “tabs” to staple to the joists. Different technology?
so when i was being told at 21 years old to put the paper side facing out into the room, it was wrong? and this instance i refer to was on a wall not a ceiling like you were doing. or does this rule apply only under a floor?
really wish you showed how to do the ductwork, that's what i came here for
Me too no one has a video on it.
Why would you not use thermafiber/rockwool on the rim joists?
It looks like your using wool insulation instead of fiberglass and what are you using over that metal ducting?
Got to use insulation knife
my wood floor started to pop up shoul i do this?
At 4:49, I wondering why the it should face up? I searched online, most articles recommended to facedown so you can staple it. Also it says the paper should face the warm side in winter time. Isn’t the basement warm in winter?
In a climate controlled house the upper levels are always gonna be warmer than the basement, whether it is winter or summer.
Do u think i can do to myself 😮, my crawlspace
Great video sir, i have a garage with a flat roof, in the inside i have 2 x 6s from the garage door to the back, i waant to use r19 with the paper, should i put the paper against the plywood? Or facing down? , just for information so you know what I have, . is a flat roof , on top i dont have shingles, i have the tar roll and then the other roll that has like lille rocks. Inside of my garage, the side walls are made of blocks and stucco, and the 2x6 go from wall to wall, so there is no wood exposed to the outside, . i just want to find out if the paper goes up or facing down to the inside of the garage, can yoh help me please? Thanks in advance...
It seems for your situation the paper should be facing down, towards the inside of garage.
@@D.I.Y._All-in-One thanks a lot for the fast reply. Appreciate
I think if I was to do our basement over again, I would insulate the ceiling and then cover it with reflextic.
What if you have a bit of moisture in your basement! I occasionally let my dehumidifier run!!!
Faced insulation can be used in garage attic, with faced going below and also installing plywood boards on top of joists for walk over?
Should be unfaced be used instead of faced?
From my understanding with the latest techniques, you dont want to insulate between the floor joists and only insulate the side walls. You are restricting the warm air from rising into the home.
Cut it up side down works for me paper down on a scrap of drywall with a 2x4
Would painting the formular board insulation be a problem in any way?Thank you for the info and happy NY
Contrary to what he showed, the foil should be facing outward toward the room so it protects the foam a little longer during a fire and gives you a chance to escape before the foam gasses overcome you. I'm not sure how paint would affect the fire rating.
Should I cover the exposed insulation on the basement ceiling ? Or should I just use a faced insulation facing down
Use Rockwool. Mice and bugs hate it.
That's what I'm installing today 😂
I just use my wife's cooking
@@DrJoonPark hahaha. I wouldn't dare say that... the Humane Society would lock me up!
Wow thanks !! My house was built in 1951 and the whole house insulation is rock wool !!!!
I didn’t think that they made it anymore !
I have trusses instead of beams in my basement ceiling. Should I fill the truss space with something?
Na just a compression fit in between the trusses should be efficient enough, and use staples with nylon strapping to secure it.
how to you hold the insulation when you have a truss system in the basement
Use nylon strapping, and staples it to the trusses, to secure the insulation.
Would you get more out of doing the rim joists vs the floor?
Insulating both is better. Rim joists are on the outside wall, so it's a more vulnerable spot.
I installed insulation in my garage ceiling, but I put the paper part with the lettering facing the garage floor. The sub floor in my house is wood. Do I need to flip it?
I don't think it's worth messing with, since it's already up.
@@D.I.Y._All-in-One Too late. I already flipped it all🤣
Rockwall I've used in my cabin and mice dig through it and so do bugs so the first comment is faults
Hey if you're giving out free answers in the comments section, I got one for you. It's a wraparound deck that got closed in, so totally exposed joists and subfloor. Paper side towards house? R19 fiberglass? Very humid Eastern NC.
paper side always toward the warmest side. I like mineral wool better than fiberglass since it is pretty much inert, made out of rock.If this is on the exterior of the house, I wouldn't use paper since insects will probably get to it, and may eat it, also paper disintegrates when wet, and it promotes mold.
Should you insulate the basement if you use it? Mine is unfinished however it is heated and i have a workshop down there that I use. I always assumed the heat rise would help keep the main level warmer?
Ceiling no, walls yes
I noticed my friends home basement is warmer than ours was. My theory is that his basement was below ground level ours was open on the north side for a door going outside. And the other half had two garage doors 8 feet each. There was a partition between the two sides. The garage side had no heat. The basement work area side had the furnace and gas hot water heater and tank (split unit). So under ground is natural insulation. 73
It is so hard to find instructions on how to insulate between crawl space floor joists. Almost everything I see in youtube is people encapsulating their crawl spaces instead. I didn't ask for that though. Sure, I'd love to encapsulate my crawl space, but it costs several thousand dollars to do it, and I'll have to pay someone else to do it, because it is more complicated and requires training, specific materials, and experience to successfully encapsulate a crawl space.
I have 4 inches of insulation between the joists in my crawl space, and there is a gap between the floor and the top of the insulation. I do not know if I should remove the 4 inches and replace it with 10 inch insulation, or just add 6 more inches; but I am leaning toward adding 6 more inches to what is there.
What type of insulation is that, and is it old and dirty? 🤔
Have you ever seen floor joist spacing at 32" on center?? Mine are. Dunno what the hell do. The old insulation is 30 years old and deteriorating.
You could try thick foam board 4x8 sheets cut to size. Might get expensive though. You could also add some framing to the Joists to make the spacing smaller.
Definitley add new joist... use the metal hangers they use for decks... super weord. My house is a 1949 and has 16 on center
I'm doing a 120 year old house, irregular joist spacing. Very fun
@@ThePinkPanth3r my house is over 120 years old and it's pretty regular, it's got real 2x4s I can't imagine having 32-in joists, I'd be scared that the flooring would fall through
Run the material sideways in the bays and strap it.
What’s to keep mice from eating this stuff
Using a utility knife to cut insulation is a pain in the ass. I used an old electric carving knife to zip right through it!
why do you need insulation in in basement ceilings?
I gonna do this because I wanna get more soundproofing
great thank you. Damn cheap seemingly compared to Canada! :(
Excellent. No B S.
Glad you liked it!
I thought you had to leave 100mil between insulation and the ceiling/roof to prevent mold
I thought so too. Any answers.?
Not when both levels are conditioned
really....Menard's
Ugh, I just hired someone to do it.
I thought you weren't supposed to insulate the basement ceiling. Rather, frame the walls and insulate them.
Some insulation could be for keeping a controlled temperature in a specific room
No the heat from the basement keeps the floor warmer. If no heat is under the house the ceiling should be insulated and walls. Craw space should have a vapor barrier on the ground.
My parents had a cottage that had craw space and the furnace was under the house on blocks. The furnace guy cut holes in the floor for return air registers, the under the house was one large return duct. You had to go under the house to change the filters. A man hole door was in the bottom of one rooms closet. You could also go under the house outside as well.
Now nothing was insulated under that cottage. But the cottage was always warm including the floor. Most floors had Linoleum and living room had vinyl carpet. The furnace under the cottage was natural gas. 73
People insulate the ceiling in the basement to help with soundproofing.

Fibreglass should be banned.
I was planning on putting insulation in my basement ceiling in one bedroom that isn’t finished but it has the circuit breakers so there tons of electrical wires going every different direction. Should I just mash it in above the wires/fiber optic/cable wires?
No, you split the insulation to the proper depth so some insulation goes behind and some goes in front. Mashing the insulation reduces the R Value.
Excellent and thorough video! thanks very much for putting this together.
