Traditional vs Advanced Framing - Details

have you ever heard someone say that house has good bones what are they talking about of course it's the framing super important for a well-built house to start with a well framed house on the build show today we're gonna talk about advanced framing versus traditional framing and go beyond the typical discussion which is just should I frame my house on 16 inch or 24 inch centers like you see here I've got a special guest for today's build show it let's get going alright guys let me introduce you to my friend Steve basic Steve you're the architect on this project and I want you to tell us a little bit about why you chose to do advanced framing on this particular house all right so we're gonna start out with a little pet peeve because you already pushed a button oh yeah so advance framing let's just call it smart framing because there's traditional framing advanced framing all these different kinds of framing packages but I like to look at it is the framing is just one of the systems in the house and for particular projects you need a particular system and so in this case here you know a 24 inch on center framing system worked in just really good with what the system overall package was here so we can call it advanced framing call or whatever you want but it's really about making decisions that are appropriate to the overall decision being made on the project I love that so you know when I hear advanced framing sometimes I think oh we're trying to save lumber or save money but in reality it's being smart and designing it from the start now let's talk about this how Steve this is what a 2,400 square foot house yep yep plus we're actually in the garage I've 600 square feet of garage here good side okay so 3,000 or so feet under roof on this house and in this particular case we've got trusses above us here which are actually landing front to back on the house so we're clear spanning the garage there we've got no posts in the garage no posts in the garage no posts in the house so the whole house load is brought down to the outside walls which is where the outside foundation wall system is so it was inevitably the decision when I were you know working with the Builder Jake and we came up with the idea that's let's framing up those outside walls let's throw the roof on there get it closed in with some zip sheathing get us nice and weather tight real quick but now we have a factory to do everything else inside here sometimes when guys talk about oh you know it's better to do things off-site and you get better quality well if we build a little warehouse here then we can control the environment and get good quality on everything we do inside I so true it's like a little barn isn't it all right so then talk to me about some of the details on this framing so we've got 24 inch on on these outside walls 24-inch aunts on Center framing right all the studs aligned with the trusses up above okay we have our trimmers come down notice we don't throw the extra jack in here they actually take the time to cut the set the sill okay and then run the trimmer up above that so it eliminates a little inside of that gotcha and then that goes up to our header I always insert a header plate on the bottom that helps us catch all the trim and stuff on the windows gotcha but then notice that we do an appropriately-sized header and then that creates a header pocket yep so lvl header right there and then that plate right there that's your 2 by 6 that you're using underneath that header so now our trim and everything's gonna sit well flush but the beauty of this is you know I always talk about the framer gets to do what the framer does when the framer should do it so we're not out of sequence and any insulator when he comes he can insulate that pocket when it's time for an insulation to go in and the insulator does what the insulator does when he needs to do it yeah so we're not asking somebody to come and just spray that we're not asking the framer to mess around with two inches of rigid foam and build insulated headers we get what we get through the normal sequence of stuff now Steve I'm also noticing now it looks like the insulator is coming a little early but your your trust is seen to be quite a bit higher over that top plate what's what's the theory behind so the what you see up there is the trust industry calls that a slider so you notice that we basically took a two by six and we slid it down in between the joint of the bottom cord and upper cord and what it does is it basically splits those cords and it elevates the heel height so we get a little bit more insulation above the wall which is traditionally you know the bad decision of just having that little throat dimension of like four inches is now 10 inches so we get really good adequate insulation so now of our wall plate yeah all right now I'm noticing you've got double top plates here and a lot of times when I read about advanced framing they're preaching single top plate as little lumber as possible what's the difference between the single and the double up there so again when we look at this the system as a whole we will come to understand that the sheathing on the outside is our shilling right so that means we have a one inch poly so panels like this but it sits on the outside of the house okay and because of that then we've picked up some of the losses of the thermal efficiency in the house by simply having that our sheathing on the outside of the house gotcha so because we do that then I don't have to nickel and dime the framing package and beat up the framers this particular framer who does an exceptional job he likes the double top plate because it does it helps him straighten out his walls and it keeps him in you know a traditional mindset but we're still building a wall that's better than what's traditionally built got it so these walls in here are what 10 foot tall is that right yeah they're well they're nine foot walls ten nine foot ceilings from the plate to their Gaucho and then I'm seeing these two sheathing breaks here I don't normally see those in this location what's going on with that yeah so we we couldn't get the 10 foot zip art panels here so what the framer chose to do is to keep that blocking in a comfort range right so they're not working off of ladders or scaffolding to deal with the joints so they railroaded the lower piece they railroaded the upper piece and then they put that joint in the middle so now all of the blocking and stuff is done in a very convenient level gotta that makes sense now tell me about this hardware I'm seeing over this big header on this window no no this window just for clarity it hasn't been cut out yet check out our other videos about why but talk to me about that clip right there Steve so that's just a simple header hanger if you notice that we went down to a single jack here in the code and you know window openings over 3 feet would require a double jack okay but one way we eliminated that other jack was to simply put in a header hanger there which adds assistance to carrying that header gotcha that makes sense and then tell me about insulation for these cavities later because you've got this big five and a half inch deep cavity plus we talked about this zip R which is one inch thick that's going to give you our six point six on the outside then what are you gonna do inside the so on the inside we're gonna splash it with an inch of closed cell foam okay we're probably bringing that up a little bit and then we're just going to fill the rest with a blown fiberglass blown in back H I mean this this is a house that you know we care about the decisions but it's still a house that's kind of in that commodity realm where we're showing people that you can build the average house really well yeah right that you don't have to go over the top to build it to get a really good house and honestly the the are six outside is more important than anything we put in the cavity right right because he's got a you've got all that continuous on the outside without any breakage because each one of these thuds is probably around are one per inch well yeah are one either of our sorry two by six stud is about our 5.5 okay right so when you look at a wall system if we were able to take all of the exterior walls in this house and make them one wall all right that would suggest that about twenty percent well probably about eighteen percent is framing okay and that's our five ish right right sixty three sixty four percent is cavity so that's your true r-value in the wall and then another 20 percent ish is windows and these these windows are better than your usual you know point three windows these are going to be closer to our seven our eight ones they're triple glazed so we elevate that but understand that those three major components that make up a wall the minute I put our sheathing on the outside it improves the sixty percent of the cavity area but it also improves the 20% of the opaque area where the framing is and ineffectively more than doubles the r-value at the opaque framing so when you normalize those values it brings your our value way up right I had one of the the best building scientists I've ever met and I sat down at lunch with him one day and I said hey Gus what what's the best wall we can build you know what give me the skinny here I'm a young architect I want the secrets right he said it's real simple put as much insulation as you can afford on the outside of the house you'll never go wrong smart really smart Steve anything I missed on the topic of framing in particular in this house that you wanted to mention no I mean but you know as we look at the expanse you know again you can see that the because we're carrying it from wall to wall it gives you this factory environment and do everything you know and we were able to do some good air sealing details and all this stuff you're going to pick up in some later videos but it's just kind of creating that enclosure so that we take in on site construction project and make it more like a factory built environment as we inevitably built our on-site factory here so awesome guys for more on this project this is called the hybrid house right sure Steve's the architect my buddy Jake Bruton with Aero builders in Columbia Missouri is the Builder here and Jake is brand new on our network that we've just come out with so if you don't know about that go to build show network.com gonna have several videos including several with Steve telling you the behind the scenes on this house there's a lot of technology behind this house it's not expensive it's just smart and Steve and Jake did an amazing job in designing and building this house in doing it on a really reasonable budget of under two hundred and fifty dollars a square foot for this house for some amazing both scores and performance and products going in here but really off-the-shelf stuff so go to build show network comm follow Steve on Instagram we'll put a link in the description if you want to see more of Steve's work too we've actually shot a bunch of videos with Steve from Boston where Steve is based out of so I'll put a link in the description to those as well Steve built several passive houses and some amazing projects if you're not already a
