With floor trusses being built this way to begin with it was a huge step for the world of i joists.
Floor trusses vs floor joists cost.
Though i joist sales per housing start have increased about 6 over the last two years the trend has slowed considerably.
Vibration control with minimal effort and cost.
Superior strength to cost ratio thanks to no need for steel connectors and efficient use of wood fiber with a state of the art robotic manufacturing process.
Depending on the local building codes and the contractor s.
All wood finger joined joists are installation friendly for framers and mechanicals.
To which rick responded.
This also reduces the need and cost for extra bearing posts beams and footings.
By only covering the trimmable end of the triforce open joist your floor system will be fire compliant as per exception 4 to section r302 13 of the 2015 2018 irc.
I m thinking it would take a little more math on the builder customer part to compare against labor.
Floor trusses are going to run around 4 40 per lineal foot spaced 2 on center this makes the cost per square foot for the joists at 2 20.
Cost effective light and safe.
Floor joists are a part of the structural support of a floor.
Some of the small gain is due to the continuation of the replacement of solid sawn joists.
The one thing con you forgot to consider with floor truss vs traditional joists is that they are much weaker in a fire situation and will collapse long before a traditional floor joist will.
Alex this is actually not true of trusses.
Floor trusses can span farther between bearing points than i joists allowing for larger open rooms.
However most of the increase results from the national builders market share growth.
For a floor span of over 24 trusses are certainly the way to go.
They support the weight of the building and absorb impact providing stability and security to the overall floor system.
The biggest advantage in my opinion in using i joists is simple.
Ewp is resourceful for many reasons some of which you may already be aware of some of which you may not be.
I just did some checking to confirm.
