How to Insulate a Basement Floor FAST 

They really should of doubled up the thickness of this panel... They only reasons I don't want to do coventional polystrene is the lower psi and cost of plywood.

@@adamkebede6015 just double it? just a guess

I just stumbled on this video too, and am interested in purchasing it in Canada. Do you have any 💡?

Did you end up trying this in your garage?

per the instruction pdf you will need plywood or OSB boards to spread the weight on top because carpet is soft and does not spread weight.

@@tim_yrt but do you have to use 2x4 sleepers also or can you just lay plywood down on top of it? I have the pdf and it says to screw down every other board to the cement floor and a screw in the center and then you can put the carpet tacking strips into the perimeter.

I took it to mean you don’t need plywood on top. I hope not because I put down these insularmor boards and am having carpet installed on Thursday. 😮

@@ballerina6179 sorry I'm not an expert, still haven't started my project yet. I'm pretty sure the PDF meant to screw down any weight spreading substrate with the insul-armor. Hope you can make it before the carpet installation.

@@tim_yrt yes you’re right. Omg. The FAQs on the big box store site had a link to the pdf but it was for the Dricor small panels that already have OSB on them- not the insularmor big panels which have a better R value and the ones I used. Now I have to borrow a pickup truck and hope they’ll make the cuts I need to properly stagger the joints and fit it in my room. I could cry right now. The only good thing is I have an unopened box of insularmor to return.

one question is, how to seal concrete completely?

Is that not what the channels under the foam are for? To let moisture evaporate? How do you seal the basement floor properly??

@@bruceli6770 Sealing concrete completely in an older house is next to impossible. I would approach this as follows: waterproof the walls outside with blueskin membranę and platon display membranę, then insulate with exterior Type of panels. Replace the weeping tile and wrap it and the fresh stone around it with a lifetime warranted landscape fabric to prevent silt from build up. Do radon testing for 3 months in the winter. Radon is the second leading case of lung cancer, but most people are blissfully unaware of this. Seal wall and slab hints with caulking, install radon mitigation system if necessary. Frame walls with steel studs, isolate them from concrete at least by using a sill gasket. Do not use fiberglass insulation or polyethylene vapor retarder in the walls. Then use Platon dimple membrane on landscape fabric to prevent clicking, your choice of foam insulation and plywood. And here is the trick: cut a few fake registers to expose the concrete in few places. This will allow any moisture to evaporate. Potentially you could bring a branch of duct to blow air under the floor, but this might be a bit of an overkill. A good idea would be to redirect all duct outlets to terminate right above the floor. Newer houses built after 1995 will already have a reasonable exterior waterproofing in place, so this expensive project can be avoided.

Hi Bob! That's a great question and I wondered about this like this, too. I made a second video after this one, and I includes a torture test where I drove over these foam panels with my pickup truck, first with hard-surface flooring on top, then driving directly over the bare foam. You can see the results at this link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HtYoDYL-fy0.html Let me know if I can be more help. Bye for now and thanks for watching! Steve

Hi. Use concrete leveler and then the foam on top of the new smooth slab. That'll do.

Home Depot carries this product now (at least in Calgary).

You have to put a hard floor on top like plywood or 7/16 osb. I just found this out last night before my carpet install in 4 days. I’m scrambling to get plywood installed.

According to their installation instructions, it is recommended to install the walls on top.

According to the installation instructions, if installing hardwood, laminate or LVP, the installation instructions say you can install the flooring right on top. If installing carpet, you will need OSB to spread the load of furniture going on top.
