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.

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!)

@D.I.Y._All-in-One 2 года назад

You can do it!

@instrumentsponge 2 года назад

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.

@Chris_at_Home Год назад

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.)

@Warruz27 8 месяцев назад

Just remember you should be using different insulation if its a vented crawlspace.

@chazp3496 7 месяцев назад

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.

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.

@BigBrotherIsTooBig Год назад

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 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.

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.

@troy3456789 Год назад

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.

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.

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.

The basement work area side had the furnace and gas hot water heater and tank (split unit). So under ground is natural insulation. 73

@pampierce Год назад

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.

@ronb6182 Год назад

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
