My house built in 1990 has an 1" white styrofoam panels outside of the housewrap, covered then by ceder siding. Underneath, there is nothing stopping bugs and rodents from wanting to come up through the styrofoam!

Same here in Atlantic East Canada, on Prince Edward Island. Parents had this build in n1983 and I see rodents getting into the rigid foam that is covered by cedar siding!

Matt and Steve. It would be nice if you also talked about the cons of using TJI floor joists. There are serious hazards when you start comparing them to solid sawn lumber in scenarios when there is fire involvement. There are still very serious risks with home fires and time to get out of home is severely shortened when using engineered products like TJI and LVL. Sawn lumber lasts 3x longer under fire conditions. Also, the impact of a single failed TJI due to fire has far more substantial overall impacts on the structural integrity than that of sawn lumber like a 2x10. Homes are people's biggest investments and while fires are not extremely common they are real concerns that should be accounted for when building a home. The same way we account for other disasters such as tornados and floods. The time to evacuate is substantially less just based on the petroleum based furnishings in our homes of today. Then the risk goes way up when you factor in the engineered lumber.

[@dlg5485]

This warm board is a nice product. As long as your house isn't too huge, it's probably not too expensive. It's a great way to get the comfort of radiant floor heat without the complexity of a typical system.

[@guytech7310]

1. Its much easier to premount the floor joist hangers before putting up the joist. You mark up the rim boards, nail in the hangers than slide in the joists. You also need to install squash blocks on TJIs joists so the hangers have wood to nail into from top to the bottom of the hanger. 2. Joist twisting is the prime issue with long joists not the sagging or bowing of the joists. In TJIs the top and bottom flangs is to stiffen the vertical center so it does twist of bend under load. 3. Its would have been easier to pour the basement floor slab before installing the first floors since the pump truck has access everywhere from the top. 4. Better to install subflooring like advancetech, first than install Warmboard S. While standard warmboard is 1 1/8 it has about 7/8" routed out groves for the Pex. Warmboard R can be installed after all the walls are up which is helpful if you need to make some interior wall adjustments. An alternative to Warmboard is Ecowarm which has a alum spreader, but is easier to work with during install instead of Warmboard's heavy alum. sheeting. 5. Putting warmboard in the basement is probably a mistake. Better to use an insulated slab and install the PEX in the concrete. Issue is that if you ever a a leak in the basement (ie busted pipe, washing machine overflow, etc), its going to warm the warmboard panels. 6. Instead of using Wood for the Zip-R use composite deck boards since they will not ever rot. You have to rip the composite deck boards using a table saw. You can also prime the outside of the rim boards with paint as layer of protection. I like to mix in borac salt (insectide) into the primer for added protection against termites and carpenter ants. Better to use standard Zip and use rigid foam panels instead of the Zip-R since it can be a really pain to nail the ZIP-R to the wall studs, especially when your butt joining two ZIP sheathings on the same Wall stud.

[@normanmfakierjr2387]

Matt, Ive been following you for quite some time but this was great, great, great!!!! Thanks

[@yodaiam1000]

Good info. Your rule of thumb looks somewhat optimistic for span length especially for the joist systems. I find at 20', the most economical joist depth is 14". You can go shallower but the joist has heavy duty flanges and you get more bounce. Some joist suppliers don't recommend the blocking/bridging due to potential squeaks. Even with D.Fir, I don't span more then 14'6" with 2x10. There is just too much bounce even with bridging and 3/4" ply.

[@stevenbaczekarchitect9431]

I agree with you, I was quoting the code in these instances

[@MegsCarpentry-lovedogs]

Steve, yes, I remember Matt talking about the detail you have about the double plate, with one being a PT closest to the concrete foundation and that lower double plate being wider to create a "ledge" for the zip R sheathing. I have added this detail to discuss with the design person for this thick wall, air tight extension hoping to be ready for next year to put up. I was planning on another "winter coat" layer of rock wool board 80, to be an additional 2 inches. Steve, what would you recommend to have on the bottom of this product? I saw on the internet a metal U shaped trough that could be made and the U shaped was metal mesh design to prevent rodents from crawling into it. Like you said, for rodents possibly a nesting spot, even though rockwool product alleges that rodents do not like to nest in it and exoskeleton of insects get ripped off if they burrow in rockwool. Thoughts on this Steve? Yes, I saw Matts vids on this additional RWB addition. Around the windows gets to be more time consuming to buck out further the window sill. Belt and suspenders eh! Patience and building science collaborating. Cheers from East Canada, Atlantic Prince Edward Island☺🇨🇦👍

[@stevegoodman3692]

I like the idea of adding the pressure treated wood under the foam as its own independent block. I do worry with the suggested alternative method of the 2x8 pressure treated mud plate as an overhang to set the Zip R9 on we just created a bridge for water coming down the ZIP to bridge across the mud plate where we did not use Lexel between the mud plates. It seems having the "Rodent Block" be separate would give us a place to weep water.

[@michaelschneider-]

.. Our In-Floor Hydronic system NG fired has 3 inches of concrete with PEX-ALU-PEX imbedded. The system's concrete component provides a flywheel of warmth.

[@danmccoy6164]

I have both. Inslab downstairs and. Warmboard upstairs. Problem with flywheels the take a lot of energy to get going and then a long time to slow down. Took all day to get the downstairs to get up to temperature. My house has r30 walls and r65 ceilings. Upstairs was warm in a couple of hours. I have ambient thermostats. Upstairs with warmboard stays within + or - 1 degree of the setting on ambient thermostats. Downstairs Inslab overshoots the thermostats + or - 4-5 degrees.

[@clarencekawah4885]

👍👍💪💪 clarity!

[@johnfoley2582]

Do these I-joist require web stiffeners/squash blocks at bearing locations? Also what is your method for preventing termite damage? I ask because you don’t call for termite shield under the mud plates.

[@sparksmcgee6641]

Like Sachco also but using 10oz tubes on that foundation was painful. A sausage gun is a tool I kicked myself for not buying sooner once I bought a case of material. A roll product would be even better though. It would allow them to guarantee a seal at that point since it would have a fixed amount that could be tested and get a EC-XXXX.

[@mattlafy]

The structural wall section from Ep. 4 and this architectural wall section differ in which mud sill is held down by the anchor bolts. It's quite important that when they built it the structural was followed because you are only overlapping the sheathing with the upper sill. If you were to bolt the lower sill and only attach the sheathing to the upper sill you wouldn't get the sheer value of the sheathing holding the framing to the foundation.

[@stevenbaczekarchitect9431]

Yes I need to clarify detail. The framers install a 3"x3"x1/4" washer flush to top of top plate - see 52:15

[@grand04gt]

I really like what you are doing just are you not worried about using a liquid based heating mat throughout the house in conjunction with engineered wood framing? If it gets wet and degrades the structure of the wood would it not essentially be a potentially catastrophic failure waiting to happen?

[@TRYtoHELPyou]

Very cool, thanks for sharing. I wonder if its ok to just run the Zip-r flush with the footer, run the sill plates inside that 1 7/8, and just set the joists on top of that (obviously the joist would be shorter overall, but still. Doing that and taping from the surface of the zip R to the surface of the concrete would make one clean flat surface.

[@stevenbaczekarchitect9431]

No No No, we have done moisture tests on that detail and the lower 2' is twice the moisture content as the board above - I find that detail dangerous, except for maybe Phoenix

[@hodesto]

Great series you guy's are doing. Really appreciate your time. Question about the basement. What is the thinking behind not putting the radiant tubing in the slab and going with Warmboard R. Is it only because of a finished wood floor? Thanks

[@jeffbrenner4313]

Steve, great series! I'm a nerd so this is right up my alley. I do have a question... Can you explain the use of drop beams in some locations and flush beams in others? Why would a flush beam NOT be the right option? In the case of a basement, it would seem to always give a better ceiling height.

[@stevenbaczekarchitect9431]

Flush beams are slightly mor labor intensive to framers because of precise cuts and the joist hanger requirements. Dropped beams , the joists simply sit on. I use dropped beams when a wall aligns or they are in open / unfinished basements

I grew up in a 1960s home with hydronic floor heating embedded in the slab. It was awesome to walk bare foot in the winter! However, that system was very slow to respond to temperature change. It is intriguing to see that there is a modern version that is responsive. The only drawback is cooling. I am assuming a separate system will need to be installed for cooling and ventilation.

The "I ve seen" crowd can line up and put all the money they have in a trust account and I'll match it. We'll walk into a ASTM testing facility and watch the rest. I walk out with your money. It's stronger for a set mass than lumber. Performs better. And every house has a pile of drywall scrap in the trash you can use at no cost to boost the fire rating if that's your thing. Facts

I would like to know what is the difference between using lvl beams or steel I beams ( cost or strength or something else ) Thanks for all the great Info

[@stevenbaczekarchitect9431]

Steel per strentgh is cheaper, size probably smaller. THe balanced cost is the framers are cutting wood with lvl's. The steel is not so easily modified, attached to, or attached to structure.

Amazing attention to detail. Is ICF considered for full houses? Seems it would meet a lot of your criteria for this house without so much engineered wood. Full insulation at rim joist, perfect straightness and strength instead of lvl studs, continuous insulation, air tight without even trying.

[@sparksmcgee6641]

ICF is hyped way beyond it's abilities by salespeople. And your "perfect straightness comment referring to ICF must be a mistype. WAY better products out there that cost way less and are easier to use.

@@BriceSorg first concrete wall I poured was 12" thick and 20' high. I did it on my house. ICF is so far behind basic standard building practices it's laughable. Walked a multi family ICF with all the money they needed and the site manager walked me through what it looked like a week after the developers was on the news vomiting out the same "the construction world doesn't understand this technology blah blah blah" without a doubt THE WORST multi family job I had seen. A lumber framing job off as far as it was would never pass an inspection. It would have to be torn down. Thicker ICF allowed being out multiple inches. The most experienced ICF crew from the manufacturer was used. I don't think they went bankrupt but it was close. Ended up pre selling a bunch of units from the hype at $350sf then after the last theid didn't sell for 9 months in a bomming market they dumped the units for 60% of the presale price and disappeared. Raped the 15 or so people who bought the hype. The HOA couldn't get maintenance done because they would get bids and swear no one knew how wonderful ICF was and would get 10 more over a few years until they realized it was shit and they couldn't maintain it. Most of the units walked a we at from them in the 08 downturn. The building was in a booming area of downtown Denver. Never slowed down in that area during 08. I owned a house 50 feet from the project. Watch it all from and center for years. Good enough for ya???? 25 years in construction building Spec houses in Colorado. Top tier houses for 2 decades. Want Bret Hull if you want to know what top tier is.

@@sparksmcgee6641 12” thick 20’ is a beefy wall my guy. What was it for? I understand people may do a shit job but I don’t think that should represent the product. I poured my 3500 sqft personal house first floor yesterday and was off maybe an 1/8 at most at 10-12 feet with 4 guys 55 yards finishing 17 windows 5 doors. Wet set truss brackets with 20,000+ pounds uplift rating. To me it’s a no brainer. I’m not even a concrete guy I mainly do siding, replacement windows, exterior trims and we have seen so much terrible work from boom before 08 on spec as well as custom homes. No window flashings no apron flashings no care taken. One spec company actually flashed j channel underneath j channel in windows causing rot underneath every one. If anything , terrible building practices with water which should be #1 priority effect ICF way less. EPS and concrete? Automatically solves for water and air infiltrations. Cheap house wrap for suspenders. I have seen Brent Hulls work and it is fantastic. But who can afford that? And no offense most of his beautiful mill work is in the inside and could be done in any ICF house. Not saying it’s the best for everybody or every job but made sense for me and I haven’t regretted it.

Steve: I heard somewhere that using radiant heat flooring in houses with high insulation values is counter-productive. The hypothesis is that the house never cools down enough to really cause the radiant floor to warm up sufficiently. Your thoughts on this? Love the series, getting lots of ideas from this and Jake's Building on a Island series for our retirement home.

[@stevenbaczekarchitect9431]

I have it in very efficient homes, the basic premise of a radiant floor is warming the surface for the luxury of a comfortable conduction - hence the luxury. The system is temperature based, the radiant sytem's only knowledge better performance is lower temp and circ time........and it is Wade on the Island Project

And I keep the ambient thermostats set at 68°. I can walk around naked. Warm feet no cold spots. Lol.

24' span rating for the joist, installed on a 20' span - the enhanched strength offers stiffness and damping which in turn provides enhanced comfort

Don't all things of value cost money? It's a client choice - we could always not do it........Just like Mercedes owners, they could buy a Honda, still gets them there, but not their choice

[@magictrading8903]

@@stevenbaczekarchitect9431 hi Steve, all due respect the value proposition isn’t as subjective as the value of “clients want it”. The example I give is metal vs asphalt roof. In most cases metal cost 3-5x as much. Say a metal roof is 50 yrs to life and asphalt is 20 yrs. Not if you factor in the fact that cash saved by going w asphalt can sit in bank and earn risk free interest means in 20 yrs when the time comes you will easily be able to buy another asphalt roof, or put the money towards something of more “value” now in the build. Warm board isn’t the only way to do it and I suspect (at least for me) it didn’t make sense ti spend the money on it when I could achieve what I wanted in a different more economical way. That said I see the value in a Benz over a Honda. It’s not just about point A to B, or just about a roof over your head so this very much could be the case for this build

[@sparksmcgee6641]

@@magictrading8903 magic the problem with all of the "if you invest the difference" argument is that no one actually invests that amount of money and set it aside for the repair. Also as professionals we know that the asphalt vs metal is just talk of the warrantees, actually the asphalt might not make it to the warrantee timeframe but the steel will exceed the warrantee by a factor of 2-3 at least in functional use timeframes. There are products that provide a definable objective improvement to the structure.

Does it bug anyone else that lumber in the US doesn't seem to live up to the name? A 2x4 is not 2 inches by 4 inches... just... why? In my country, a 150mm (roughly 6 inches) wooden post is 150mm by 150mm or very, very close to that. This makes it so that if I wanted to build a house out of stacked wooden beams, I'd buy exactly as many beams as is required according to the dimensions specified on the lumber and the wall height instead of having to calculate how many extra to get due to the material received being 20% smaller than what it says on the box.

iT IS A LITTLE AGGRAVATING, BUT AFTER 30 YEARS i HAVE THE NUMBERS IN MY HEAD

[@bugtusslealien3931]

Engineered wood is nice but the cost is enormous! The spanning distance is still dependant like an I/W steel beam. I'm not sure if you have sizes like a steel I beam can offer. Supports added to a basement is fine with me. It's always cold and damp and offers you arthritis! Things made out of chip board should be A LOT cheaper! You build high end homes and 99% out there cannot afford this much less the 2 bys used. These homes are like electric cars, there are entities who want to take advantage of rare elements and artificially jack up costs.. I feel that if you could make batteries out of sand then it would be a rare compound.
