They don’t use finger jointed studs out there in the desert? icon_lol.gif

Heck no Blaine


They make these really long frames (molds) about the size of a 2x4 or 2x6. Fill it with wet mud and straw and let them bake in the dessert sun. Cut the length they want and after a few hours,bam! Adobe studs. They don't even need nails, use adobe weld. ![icon_cool.gif](upload://oPnLkqdJc33Dyf2uA3TQwRkfhwd.gif)

This doesn't work to well here in Kansas, way too much humidity. One would end up with a Chia House

Finger joined studs are manufactured from lower quality pieces of lumber where the reall bad sections are cut out and then joined together with other pieces of lumber with a sawtooth joint and glue.


Here is some more info from one manufacturer, but take it with a grain of salt ... remember the snake oil salesmen of the old west ... ![icon_lol.gif](upload://zEgbBCXRskkCTwEux7Bi20ZySza.gif)

I think the “best” answer to this one is “Yes”, it would be acceptable


Model codes permit the substitution of finger joined studs for full sawn structural use lumber without any such restrictions.

Now for the sticky part. In my opinion that installation could be considered poor practice. A glued joint in an exterior wall that may be subject to moisture over time if the siding fails is not such a great idea when you really think about it.

Isn’t the glue supposed to be stronger than the wood?

Unless I’m thinking wrong, which does happen from time to time, finger jointed studs aren’t allowed here as load bearing (exterior wall) framing.


Are they in your area Rob?

… The joints/glue are suppose to be stronger … as long as they are kept dry. Moisture and glued joints generally don’t mix.


Blaine ... FL has it's own state code, which may or may not restrict the use of finger joined studs. The vast majority of the country is on an IRC based residential code which specifically allows finger joined (or "end joined") lumber per IRC R602.1.1 (also CodeCheck under "Wall Framing") as a guide.
