hi I'm Dean and this is part of our learn no lunch series and this is a great question we got from an email this week so we'll just start it off we'll learn no lunch now apparently three out of four people make up 75% of the population 50% of all experts are wrong and why am I telling you this because what I want you to know is we're gonna present to you the best information in what we believe to be true and will work best for you but you are the final judge on whether our recommendations are going to work for you so we're presenting this and there best we can for for your consumption now we got this letter I am looking to finish my basement this winter and came across this product yay this product is in so fast it looks like it will save me a lot of time money births the standard 2x4 installations but we couldn't agree more it goes on I have a question though in my basement where the cinder block meets the sill plate there is either an indentation of about an inch or a slant what was great about this particular email as he sent two pictures with it and the two pictures really helped me figure out what would work what I think would work best for for for you no here it is here is the concrete block the floor joists overhead the floor joists overhead I only have 83 inches so I gathered means 83 inches this is the top and to the floor it's 83 inches high this cinder block only goes up to 75 inches and that would be this 75 inch line where the slant starts to indent close to 3 inches so it tapers back three inches and this is only only the inch area the sill plate that's this right here is that the sill plate all started 80 inches at least so he has a 80 inch line right here 83 inches right there and this is sort of a transitional line so as you can see in this picture where the concrete tapers back it goes up to the sill plate and the floor joist is right up right up above and the floor the first floor floor is right above that though this is kind of a nice detail with these straps going across for the drywall attachment that's good and I guess this was the original drywall furring strips right there and you can see a random electric wire so his question is how do I finish off this area because I imagine the in so fast would run straight across and there's this 3-inch gap that he's that he's worried about so we do this a lot we get that question a lot and it is this transition where the concrete block wall ends in where of the floor joist and this whole transitional area starts to kick in how do I handle that he's worried about a big gap up in here and how do you insulate it now what I will tell you I'm probably more important than insulating your basement walls would be to air seal and insulate the rim joist up there that's the number one air leak in a house concrete doesn't move it's well it's a stone wood it's a natural product that swells and grows with heat and humidity and time of year if you ever noticed your your floor's in the winter are kind of squeaky and in the summer you don't hear them quite as much kids are yelling and the doors are open but the wood swells and shrinks that's the reason we built wood boats is because the wood would swell and keep the water out once it hit its maximum tightness so that's always changing so if you air seal that your house is like a chimney and the warm air rises and the cold air is sucked up right in through there so that transition is really important we have a in our technical area under interior you can get a rim joist I think it's number 16 quickly and there's a really good article on how to handle that but I don't want to handle all of that right now let's go to this particular setup and switch to this camera view so what we want you to do is insulate this area up in here billon insulation if this if it was your area it would be tapered paper insulate you can spray foam that would it would joist area up in there but it is okay for the in so fast to actually go up and above in all the way all the way to your floor joist all the way to your floor joist cuz this is a stud that it that is a stud this stud is buried into that panel and if you but that up right up against the roof and go to a lumber supply store and get a metal L angle like this and you screw that into the in so fast stud and adjust it for the floor the ceiling height screw it in and screw it in now you have a nice really solid attachment to hang the screw your drywall and hang your drywall on so just insulate this back area in here really well and then run the in so fast straight up to the floor joist if that's the look you're trying to achieve with flat even walls all the way up that's how I would approach that now going back to this particular picture oh yeah what one other thing well I'll handle it here one other thing this area right in here at the top of the wall this top of the wall you see that wire in here that gap in between there where it's you have that trough back in here this can become a really nice service or wire chase area where you can you can run cable a couple of wires you can do drops to really power your house but what I'd like to talk to you about is our typical layout on our in so fast we are starting with a full panel two four six seven this wall happens to be seven-foot high so we have a full panel full panel full panel and a cut panel up here if you want to have that wire chase run along the top and I do recommend it because you can pull wires and drop wires all them all the way down you can reverse that order instead of having a full panel down here have a cut panel let me demonstrate what I'll do is I'll show you how to reverse that wall so I'm going to set up a cutting station and the in so fast boxes make a great cutting station because they are very solid and nice to work with and we're gonna cut a pant in so fast panel in half now I know it's seven a seven foot high wall so I'm gonna cut this panel in half in on the panel itself we have little indents built into the panel little recessed areas for screw attachment so if you are mechanically attaching this the cap con screw would would indent right in this indented area and be flush with the wall so when you put the drywall on it'll run smooth but what that gives you is every six inches this is 6 12 18 24 so you can divide the panel in half real easy so you don't always have to use a tape measure and measure it so let me let me do this which i think is real important because it'll show up better on camera since we're going to cut this in half I'm gonna give it a nice orange glow nice line to follow every member in so fast is rough framing it's not fine carpentry it's not finished work you are gonna be putting drywall or some kind of finished material on it so don't be too fussy with and so fast I mean it's easy to cut if you make a mistake don't worry about it you can glue the panels back together now I'm gonna turn my mic off right here hi I'm back and you didn't have to hear that loud noise okay so there's our there's our cut that wasn't quite deep enough yeah now I would be terrible if I didn't insist that when you start within so fast you keep that running bond because the interlock of the panel's helps flatten and tighten the wall and make it a lot flatter so we're gonna start our running bond by cutting this panel you know now we got our first panel we cut you got our first panel that we just cut and we'll set it down here and we'll use our cut piece right there so now we have our first half panel cut and start here would be our second panel and that would tighten and put that all together and because we're just starting this I'm gonna brace braces faced with a concrete block so it doesn't kick out or fall so that's a nice way to hold it together because if you go too fast the walls gonna want a cup away it's going to want to push away because the weight of the panels will push that first panel out so if you brace it with a with a with a block a book a box anything to get it started until the glue sets in about 2 45 minutes it's got a first initial set and then after 24 hours you're good to go you can hang drywall so here's our first panel our second panel all right second and a half panel and then our final panel and this electrical Raceway along the top so now you have a reversed wall set where you start low and go high so thanks for watching that'll be all for today one last thing please like us please tell your friends and thanks for
