I would like to see a test again with a couple changes. One with a board without such a massive knot. Also put holes in both for vent , electrical, and plumbing. Lastly, what is the cost difference? Enough to justify a 1.5x strength?
I wish we could have seen the 2X10 before pressure was applied to it. It looks as though it may have been cracked in that area before the load was applied to it.
The I-Joist concept is great "on paper", but has a drawback: Supporting hanging loads. I have a garage beneath bedrooms in a 2 story house. I need storage space and wanted to hang things from the garage ceiling. Lucky I looked before starting. Lag bolts through the lower cap and into the webbing could have degraded their strength and nobody would have known.
I feel your pain! hehe. As a traveling certified installer of anchoring points for elevators and cranes i have seen some weird constructions. but we must always think 2x5x safety::: which means that if an anchor point shall hold 1000 pounds, we hang 2500 pounds from the points! so we most times DONT anchor cranes-elevators in wooden anchor points even if the dimensions are big normal lumber, becouse even the best wooden screw-s can be pulled out to easy after some use and wriggling. we usually install say steel beam-s between the beams-joists. that go between 2 load bearing walls.
I'm from South Africa....this type of joists are not very popular...we use SA pine and laminated beams...I REALLY like this idea very much...I'm wondering what kinda span this particular i-beam can cover...
Well I'll ask but why can't I make these?? Because of the laminated top and bottom?? 2x3 notched to fit the osb I could make whatever length I want. Interesting video thank you
What about strength of the joists, under damp or wet conditions? Seems to me then the I-joist would be WEAKER. Obviously all buildings should be kept dry, but changing weather patterns may cause temporary disruptions.
I wonder if shaping these with a peak for peaked roofs.... could make these 18ft long to span a small concrete slab for a car port or enclosed garage with a peak already in it and ready to go (obviously theres no overhead storage optio s but still super quick and easy
The l joist might be stronger than a conventional joist until it gets wet then it will do what all laminated wood does and fall apart where as the solid wood will sustain its strength
I would imagine the potential for damage is minimal. Termites don't like Douglas fur, which they specifically used for the flange. While they didn't share the makeup of the OSB (it sounds like a proprietary mixture of wood and glue - and termites don't like glue), I'd be willing to bet they took termite threat into consideration for the design of the entire joist. Using Douglas fur for the flanges would otherwise be pointless.
Thar knot that close to the edge is uncceptable in a 2btr. Engineered lumber has advantages such as consistency and strength/weight. That said, I would avoid these like the plague in my own houses. Just picturing a 3" drain pipe beinf routed through that js painful. Most improtantly, moisture damage seem like a huge weakness too.
@@sailingwiththegods538 Are you posting just to argue? I am talking about using a subpar traditional wood joist for demonstration - effectively rigging the results.

Why you the 2x10 when it’s already broke down and not from beginning. Are you trying to something? I don’t believe it and you also used the imperfect 2x10 with the eyes in the wood
I don't like the way they tested the strenght. I'd like to see another test with a smaller gap between the pressure and the resting area of the 2x10 Due to the way the 2x10 splits, you're giving an edge to the i-Joist here. That being said, the i-joist is certainly very strong.
In real world plumbers and electricians make many holes in many different places... and sometimes openings. This setup will never handle longtherm loads... If i see this i dont buy a house
Cheapest crap I've ever seen. Almost looks like chineese junk. Not to mention OSB is a mold magnet, burns like paper, easily water damaged, and can easily warp. Only time will tell if it really works
50% stronger my Oklahoma Sooner buttocks how about 50% weaker a true 5 inch wide by 8 inch tall solid wood beam made of White Oak can run circles around this those manufactured i joists and take more than 3 hours to burn through to be declared unsafe compared to just 4 to 5 minutes with manufactured i joists most manufacturers of manufactured i joists never their products when exposed to fire and i wonder why.
@@onestepunlock4475 I would because I'll build my home to last more than a 100 years maybe even 200 years the higher upfront cost will pay off in the long run.
@@rustybeatty6567 It takes around 20000 board feet of lumber to build a a 3000 sq ft house. Rough sawn white oak runs at $10 per board foot plus tax. Your framing would run you over $200K. You would gain absolutely no advantage over pine except for a better rot rating. It makes no difference because it's enclosed inside all the sheeting material anyways. Your house would be extremely heavy. Nails is a no go. You would need proper joinery. Add another 200K for labor. You also need to realize - you won't be able to run drywall screws into oak. There are plenty of houses built over a 100 years ago using pine. They will stand another 100. If you want to build a timeless fortress and willing to spend half a million on framing, why not build with brick/stone?
You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the anointed is Lord! Repent and be baptized and believe the Gospel.

Even while we were enemys, he loved us and provided payment for us. A payment you'll never be able to pay.
Try to find such 2x10 without such a big branch knot or turn it up. And then test again. No-one uses it that huge branch at the bottom.

Thank you for the how its made video. I think these are awesome!
The problem with lumber
2x12s top out at 20 feet span
I-Trusses and be built to handle wider spans
How long do they last?

I have the same I-Joists and I want to hang storage racks. Did you ever do it and or how?
Attach it the top of the I-Joist not the lower cap or webbing.
All those adhesives in the flange, and in the web material, no wonder this stuff burns so much hotter, and faster than traditional lumber.
I'm from South Africa....this type of joists are not very popular...we use SA pine and laminated beams...I REALLY like this idea very much...I'm wondering what kinda span this particular i-beam can cover...
At that dimension for the joist it can free span 4 to 5 meters (depending on spacing) before deflection becomes a problem.
@@mitchalvarado2777 Thank you kind sir
Wow awesome video! Super informative and very well presented. I learned a lot tonight. Thank you!
Very interesting. Can these be treated and used as joists on decks?
Yes
The deflection test is a bit misleading. You would still need squash blocks if transferring a load from, say, a load bearing wall to a support beam.
Well I'll ask but why can't I make these?? Because of the laminated top and bottom?? 2x3 notched to fit the osb I could make whatever length I want. Interesting video thank you
Didn’t show how the 8 foot sections of OSB are glued (if at all) together at the butt joints to make longer spans.
What about strength of the joists, under damp or wet conditions? Seems to me then the I-joist would be WEAKER. Obviously all buildings should be kept dry, but changing weather patterns may cause temporary disruptions.
My limited experience, solid wood holds up better than laminated in wet conditions. If I have a water accident I don't want my house to crash.
Just wish I knew where to buy 9.5x20' I-Joists here in Athens GA none of the box stores can get them though they do list them on their sites.
A flood or leak will damage these because it's OSB.
I believe you can get them in other materials, but you're not wrong.
I wouldn't use them in a flood prone area, in fact I wouldn't build in a flood prone area
@@JumboJimbo100 hell you can't even use them below kitchens or bathrooms. imagine a slow leak.....the entire I beam would collapse
How does the price compare?
I wonder if shaping these with a peak for peaked roofs.... could make these 18ft long to span a small concrete slab for a car port or enclosed garage with a peak already in it and ready to go (obviously theres no overhead storage optio s but still super quick and easy
I find this kind of stuff fascinating. I wonder if adding a different material in the bottom 2x2 like a long strip of metal would do
Didn’t see the board before the crack.
The l joist might be stronger than a conventional joist until it gets wet then it will do what all laminated wood does and fall apart where as the solid wood will sustain its strength
