Did this video help you?

GrittyThumbs Doups: Run the adhesive vertical so that if water were to get in, it could trickle down. Applying the adhesive horizontal will allow the water to accumulate and mold.

giesen: The last butthole to finish the rec room in my basement did it like this (minus the rigid foam, just tar paper and furring strips), and I want to strangle him. Now I have to rip it all out and start again. Put a proper framed wall in front of the rigid foam. And tape the seams on your rigid foam.

gatewaysolo104: If your basement walls are sealed and dry, why not use standard framing with fiberglass insulation?

n00bBagHead: So let me get this straight first you need to wet the cement then lubricate the hole with a mist and finally just push it in the hole. Most excellent video.

Stefan Denic: why do you do this? why not just use a armatured concrete construction as a cage and then brick blocks for all the walls? It'll trap a lot of air inside of it, making it pretty good thermal insulator and it'll be much stronger. Is it that much expensive in US?

Nearfaded: people have money to burn

N Kel: hey I have concrete blocks unfilled (with mortar/concrete...). What do you suggest. Can I use this 'bent' nail looking gizmo?

Hue Jorgan: 2.55 min. That's what she said.

yootoob: standard electrical box? what a joke. come to Chicago. lol

Josh Hefner: This made me cringe: "If you wanna install an electrical outlet you just gotta dig out a bit of insulation" First rule of efficient home insulation: You never needlessly compromise your insulation thickness. If you want to put an outlet on that wall you need to use thicker braces to accommodate the box without digging into the insulation. Additionally I didn't see enough hardware going into the concrete to properly secure those walls. I would be very concerned about the possibility of those anchors loosening up over time and those walls coming loose over time. Also, as others have pointed out, this basement could use at lease twice the amount of insulation and a concrete sealer to properly keep out moisture. Shoddy work like this is why you really have to take time to know your stuff and keep an eye on your builders. @This Old House, you should know better - shame on you!

Damita Trehan: Why did you insulate the wall in this video vs not in another one? Title below -
How to Frame Walls for a Basement Room - This Old House

Robert Thomas: I've never understood the rationale for finishing a basement wall this way. Poured walls are never plumb or straight. Frame walls in the conventional manner, leave a two inch air gap, insulate, etc. Done many this way, passes code and never had a problem. Provided the basement was dry to start with....

Rob T: Amazing! This guy really knows his stuff!!

John Walker: poured foundation s are junk! already cracked too

Garynoles: Everytime I watch This Old House they use products that I cannot find in my area (aka Southern U.S.) and have to order online (if I can find) that that gets expensive (for example the spring spikes).

Annony Mouse: Is insulating the basement walls really necessary? If so, why? Also, why are they using this sort of construction vs the standard 2x4 construction of walls?

calthmlikiseethm: So put a a few hundred holes in the concrete with the nails..

Claude Desaulniers: Very good, but your lucky you didn't smash your hand with that small hammer.

andres mejia: very smart guy thanks for the videos

yousifhela: great video many thanks.
