I’m a PM for a custom builder and we use trusses extensively. A couple other things to mention: 1) Trusses are MUCH more consistent in size. Dimensional lumber is never exactly the same width or thickness, due to the nature of the material and the milling process. Awesome Framers has a great video dealing with how to adjust for your joists being different thicknesses, but still, what a PITA. With trusses, you mark your layout, install, connect, and boom your floor is super duper flat! 2) With the addition of a load-bearing wall, trusses can be extended waaay past 30’. They can also be increased in height to span longer distances, or reduced in height for shorter distances to keep the space between floors smaller. 3) Now you gotta do a video on TCB’s! Top-chord-bearing trusses are just what they sound like: they hang off the top chord (flat piece on top) instead of sitting on the bottom chord. So if you have a basement, and want your first floor to sit as close to grade as possible and not above grade the height of your truss, go with TCB’s! Really wish I would have known about those before I built my house 😅
I hope to build a house using mini-splits instead of central HVAC. There will be small diameter ductwork for fresh air connections to an ERV and plumbing that should not compromise I-joists. I also wonder how much sound carries throughout a truss floor. I'm thinking I-beams for the roof assembly also in that I 'm leaning toward dense pack cellolose insulation and I don’t think open web trusses provide enough confinement needed for dense pack.
Do web trusses require more VERTICAL space than dimensional lumber? In other words, can a 2nd story be built on 9.5" high web truss? What is the minimum web truss height?

All I would be concerned about is the durability and strength of these webjoist, webtrusses.
Great video!

Great video! Do you have one of these for exterior sheathing (plywood, osb, zip system, etc)?
🙌🏼🙌🏼 keep the videos coming. Thank you

We are doing web trusses. I want a long open expanse in the basement without any bearing walls or beams to deal with!!
They actually do make trimmable floor trusses so you have some wiggle room for your length.
I have 3 words for you: bounce, bounce, bounce.
And what’s even weirder is webbed Joist are cheaper that i- joists .!! Makes no sense .!!!
