A Good Way To Insulate Your Basement Walls



hi I'm Shannon and I'm back here from house improvements calm and in today's video it's more of an informative video showing you what I'd consider to be kind of one of the better ways to insulate your basement walls obviously I think probably spray foam has probably would be the number one way to do it unfortunately the cost of it a lot of people can't can't afford to do it that way so this would be kind of what I would consider to be the next best thing and it's it's a little bit of a hybrid of foam and bad insulation so so you've obviously got you know bare concrete wall right you've either demoed your basement or maybe it was never developed so you've got a concrete wall this just happens to be paid to at one time but so bare concrete then what I would do is attach rigid foam usually one-inch rigid foam interlocking styrofoam to the wall rate to the concrete wall seal all the joints of that foam anywhere that needs to be sealed to create a barrier so this does two things it gives you some r-value in this case one inch usually gives you our five with most brands and it acts as your moisture barrier as well okay so we have other videos as far as how to attach this and talking about moisture barriers and that sort of thing so if you need some more information on that just check for those videos okay so you've you've installed the rigid foam and it's all sealed up then you're going to frame your walls I like to use from my bottom plate I like to use a blue wood framing or pressure-treated even because it is in contact with the concrete floor okay so your bottom plate I usually stick frame because I find in basements you know the floor is up and down a little bit and by stick framing I mean I'll attach my bottom plate and my top plates and I'll measure every stud and cut each one to fit and then toenail them in toe nailing them in is firing a nail or a screw on an angle from the side through the stud so it would come through like this and down into the plate now you've heard me preach many times about not using screws to frame this is not structural framing this isn't holding your house up would be perfectly fine here I've chosen to nail this but you could use deck screws here without any issues if you're using a pressure treated bottom plate or pressure treated lumber you'd want to make sure you're using the acq screws though okay so you'd frame your wall electrician would come in run all their electrical you know if there happened to be some plumbing or whatever anyways the other trades would run what they needed to run then then you could install bad insulation whatever brand or type that you choose to do so it would get installed and then then finally after that after that's all done then you're going to need to use a vapor barrier as well okay so it would go on this one isn't completed it's not all sealed but it would go on and be sealed up this this video is more about the products and kind of a little bit of the construction I think we have videos for just about every one of these applications as far as a little more detail on how to do it so just go to our youtube channel and look through the list and find them and watch them and that'll just all that'll piece together exactly how everything was done here but like I said I prefer this method if you're going to use bad insulation I prefer it over just a moisture barrier and nothing behind here so I think the one-inch styrofoam is definitely worth it so anyways I just wanted to show you this method and give you a better idea in case you've got a project coming up where you want to redo your basement so I'm hoping that it'll help you and speed up the process of deciding what you want to do so if you like what you've seen here click the little thumbs up button you can subscribe to our channel as well and if you have any questions about this or any of your projects you can go to our forum and post your question there and I'll answer it from there and also you can follow me on Facebook Twitter just to check out what we're doing and also we've got a patreon campaign as well where we're looking for pledges for anybody who wishes to do so so you can check that out good luck with your all your projects that you are taking on and I hope that you come back here any time you have a question or need to know how to do something thanks for watching

    Would love to see a video on basement steel stud framing, info on all the difference pieces that go with steel stuffing and tips to installing it. Considering remodeling my basement with steel studs.

    I have a 4 inch gap between the concrete wall and the stud frame because of pvc pipes running all around my basement walls. How would you recommend insulating that?. Thank you.

    If i am using 2" rigid foam board with rockwool in between the studs do i need to still use a vapor barrier? i read that with 2" rigid board it acts as both a vapor and moisture barrier. please advise.

    Thank you!

    I’m questioning the cost of this.. 1” foam board is $1.10 per sqft, R14 roxul for 2X4 walls is $0.89 per sqft. Then add in blue tick tape at +$20 a roll, vapour barrier, tapcons, foam sealant, and of course time, it’s on par or could be even more than spray foam. I was told around $3 per sqft at 2-1/2” foam depth. Thoughts?

    Hi Shannon thx for making these great videos! Have a question for you, I live in northern ontario were frost is a big factor, if im putting styrofoam all the way down the wall will the pressure from the frost cause a break in the foundation as there is no escape? What is your opinion on the matter ? Should i have cause for concern?

    What are ACQ screws? Are they the green exterior fencing screws?

    What do you do if you have a floating slab with a inch gap around the perimeter of the floor? Do you keep the insulation up an inch or two from the floor grade?
    Thanks,

    If I have a preexisting framed wall, can I just cut the rigid foam in between the studs?

    Hi Shannon, Thanks for the video. Nice to see some SK contractors on Youtube. If you have the money for extra insulation, would it be worth it to put up 2×8 stud walls in the basement??? Or would that be overkill??? Thanks For Your Time: Shawn

    Just wondering why you would not use 2" thick XPS which should yield R10 approx then build out with your firing strips with no fiberglass and just sheet rock? Seems like it would save a step and give you the insulation. What is the major reason not to? TIA

    Would this method be effective if I have painted concrete brick walls? Does the paint matter?

    My house foundation is stone and mortar but in some places it is not even, how can I go about that if I want to use this material? Any other choice?

    Couldn't be more wrong. Do not put a vapor barrier encasing the fiberglass. The foam sealed against the concrete is enough.

    Hey Shannon. Your videos are great. Do you have any notes for a stepped concrete wall (concrete and then wood above). The wood area already has fiberglass insulation. I want to insulate the concrete with rigid and then I want to frame a wall in front. Do you suggest any extra work or just making the wood fit around the rigid. There will be nothing load bearing in the wall.
