"Duck" here come the opinions.

TGI's are far better than trusses. Squeaks come from movement and trusses move readily compared to TGI's. Keep in mind all building has its recommendations. Don't exceed the recommendations.

Since ranches are typically single story tgis shouldn't come into play. Trusses are cheaper than stick built and are easier to install. If I was you, I would use trusses and keep the money for 2x6 exterior walls and extra insulation.

Why shouldn't I-joists come into play with a single story home?

What does that mean? Stick built what?

Because dimensional lumber is much better.

Using rafters.

So what you meant was don't use floor trusses or I-joists for the floor....use dimensional lumber for the floor joists?

Why are you talking about rafters when the guy is asking about floor joists?

Wow your pretty slick. Explain why dimensional lumber is better to use on a single story home compared to I-joists. Explain why it matters whether you're building a one or story story home when deciding what to use for floor joists.

Alright, an opinion thread.

It really depends on the whole construction, will the design include all mechanical in the basement/crawl space?

In the attic?

How big the house is?

Labor for installing whatever is to go in?

Insulation required for the location?

Etc.

Andy.

tji's can span greater distances than conventional lumber, the size of the joist will depend on the layout of the floor and what kind of loads it has to support. however they cannot have large holes drilled in them for plumbing

ojt's cannot span the distances that tji's can however they are made with an open web design which wires, pipes and hvac can be run through without having to drill or notch anything.

as for squeaks... ive never seen a ojt floor system have squeaks, the joints get snot glued outta them which eliminates raw wood on wood rubbing which is what causes squeaks, if the floor is framed properly, all sheathing is glued as well as the joist hangers getting a dob of glue in them before the joist is dropped in, it shouldnt be a issue
