I followed this method to insulate my basement walls & also insulated rim joists. It feels so comfortable now, the temperature is the same as the main level in my house, plus I cut my winter heating bill in half...I used to have a 5000W electric heater that would be on almost 50% of the time to maintain a mere 60 degrees in the winter. Now the heat pump alone is providing enough heat for the whole house for a fraction of the cost...

watching your videos is both therapeutic and educational. What a gold nugget your channel is

[benjaminthompson]

I’ve learned so much from you and your videos. Probably my favorite channel to learn from. You’ve helped me build a couple of decks, and a shed for my new home. You do a great job of explaining everything so anyone can understand it. Keep doing what you do!

i was told to use a sill seal under the plate, just to get that wood off the concrete and make a better water or moisture barrier. i am using 2 in recycled foam board ( less than half the cost of new) and 2x3 studs with R 15 . its probably over kill. but should be nice and warm in the cold winter in northern NY. cheers.

No other videos compare to these. I learn a ton every time i watch them. Great work and thank you!

This is a really great video. Keep in mind everyone that things change depending on codes and climate in your area.

Thank you for this video. It was extremely helpful for me to insulate my basement. The frame was done but the previous home owner did not finish it.

[s.ingignoli]

Thank you for explaining terms & reasoning. Awesome info & good presentation!!

Excellent, had to tear down a wall to remove our old heating oil tank hidden behind. Glued that same foam to the concrete and framed with 2x3 about an inch away from it. Was wondering if it was a good idea to add 6mil vapor barrier on top and you just answered that instantly.

Nice thanks you. Straightforward, no shilling

I know this is an older video. I’m doing a reno on my lower level which is half block and the upper part is framed on the block. Funny thing is after I tore out the walls, all that was there was 3/4 of soft foam board between strapping with foil and the upper was bat insulation with the paper face and a paper over that covering the studs and painted wood panelling. No moisture or mold. Been like that for over 40 years. I’ll be doing some waterproofing from inside the house using the membrane into the foundation after it’s broken up. I notice hydrostatic pressure in the lower block. So I’ll be getting that fixed all the way around the basement on that third level. I’m in southwestern Ontario where it’s pretty hot and humid in the summer and the winters can be cold but are short. I’m going to use foam board along the lower portion of the block wall and then frame my walls after sealing up the foam board seams. I want to use Rockwool For the insulation in the walls. I may spray foam the upper cavities because it’s deeper And use Rockwool over that. I’m at a crossroads with the vapour barrier. I don’t wanna have any moisture problems. I just want to know if it would be OK just to install the Rockwool between the studs and then drywall over it and finish? I’ll be taking the time to seal all the cracks and crevices along the way. What are your thoughts on the vapour barrier not being used? I have a fourth level that has Rockwool in between metal studs and there’s no vapour barrier and have not had any moisture issues at all. That lower level is fully in the ground.

I've watched two of your videos and like how you teach/educate. You appear very knowledgeable on these topics and professional. What's even better is that you're not one of those ... ahem; flamboyant/arrogant "LOOK AT ME! I'm THE MAN!" Good stuff; thanks for taking time out to share. I subscribed and will be watching others too.

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.

[willdogg]

Great video, I'm in the process of creating a basement laundry area based on this video and a few of your other videos. Keep up the good work!

[Grayman]

Great and to the point . No jibber jabber simple to understand

[jackryder]

Great video.
Do you everything step by step from scratch
First time at your channel

[NaturalScotti]

Wouldn't recommend the vapor barrier after the batts, its just going to trap moisture between the rigid foam and the barrier

[sirjohndoeofpa]

Thanks! Great video...glad I found your channel, starting to insulate rim joist and finish an unfinished basement. Great job!

[edwarddueppen]

Hi Shannon - thanks for another great video. I love your channel! I agree with many of the other commentators on this video, the poly vapor retarder is a problem. Since the XPS insulation is also a vapor retarder, now you have wood framing between 2 vapor retarders. Any moisture in the plane of the framing is trapped and will eventually rot and mold the wood framing. Better to use 2" of XPS and leave the stud cavities empty. I have used this method before and had good results.

You are the only person I dont mind the head interviews.
