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! 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.
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.)
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.
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
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.
I just looked this up and was curious if it creates a thermal bridge once compressed significantly. I know its a bigger decrease by compression with rockwool than fiberglass, but I am curious of the various types and severities...but perhaps its a bit nuanced to detect and might depend on other factors like cubic or horizontal compression. I once had the wrong fiberglass (meant for modern 6" studs) stuffed into a 2x4 wall (old school 2x4s though in this case) and the drywall was difficult to mount, but it is pretty consistent temp even in unconditioned space where we tried it before I "knew" what I was doing
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!
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.
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.
We have done this when we finished our recreation area in the basement - it does help with noise. In addition, if you use some of the space as an office, having insulation in the ceiling and the internal walls helps deaden the echo effect you hear on Zoom calls, etc. However, for the unfinished areas, I would worry about the insulation shedding lose fibers over time and creating a really bad health hazard. I am not sure if you covered the ceiling area in the unfinished space with a plastic sheet would be a good idea as it may risk some condensation problems in the joists? maybe better to cover the ceiling with drywall - if its in an unfinished area the drywall would not need to be finished coat, etc. But need to put something up even if you use a product like Rockwool. If you go to cover it with drywall and need to cut around lights, especially the recessed canned ones, a good idea would be to mark the lips of the cans with lipstick or something like it. Then put up the drywall exactly where you want it to go. This marks the drywall exactly where you need to cut the holes. Take the drywall back down and cut it with one of those tools they make to cut the circles and then put it back up and it should fit. But in any case - the insulation in the ceiling needs to be covered with something.
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 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.
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?
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...
You would need to install rafter vents and then install insulation paper down. Because if the insulation is in continuous contact across the roof it will cause condensation.
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?
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.
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?
Were you inside the house when installing the insulation with the face facing you? I thibk (butbim not positive) that the face should be away from possible moisture. Inside a house, the moisture would be outside so the face should be inside. In the basement, the moisture would come from the basement so in the ceiling, the face should be away.
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.
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.
@@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
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?
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
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.
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.
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 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
Instructions simple. Great “show & tell” instructions. Just what I was looking for.

Do u think i can do this, to my crawlspace?
Instead of using a utility knife, go to the kitchen and grab the serrated bread knife that never gets used. Cuts insulation GREAT
Thanks for using knauf/guardian! I work at the wv plant! It’s awesome to see our insulation installed! ❤
I use 2" of polystyrene sealed with foam and then 5.5" mineral/Rockwool. This made a huge difference.

In a climate controlled house the upper levels are always gonna be warmer than the basement, whether it is winter or summer.
Good job with your video and I see you’re saving big money😉….
Wonderful video thank you
Glad you enjoyed it
Should you leave a gap between the insulation and the floor above, or push up directly to the subfloor ?
Use Rockwool. Mice and bugs hate it.
That's what I'm installing today 😂
I just use my wife's cooking
@@DrMatthewHudson hahaha. I wouldn't dare say that... the Humane Society would lock me up!

Awesome work. Thanks
Thanks for such detailed explanation.
Why would you not use thermafiber/rockwool on the rim joists?
I think if I was to do our basement over again, I would insulate the ceiling and then cover it with reflextic.
Should I cover the exposed insulation on the basement ceiling ? Or should I just use a faced insulation facing down

Cut it up side down works for me paper down on a scrap of drywall with a 2x4
So bats under floors in-between the joists will eventually get wet, fail, & fall.
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.
Thank you for sharing
Thanks for the video
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.
It looks like your using wool insulation instead of fiberglass and what are you using over that metal ducting?
Do u think i can do to myself 😮, my crawlspace
Thank You! Nice Video.

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.
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.

Rockwall I've used in my cabin and mice dig through it and so do bugs so the first comment is faults
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!
What type of insulation is that, and is it old and dirty? 🤔
my wood floor started to pop up shoul i do this?
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.

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.
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.
