Builder using finger jointed 2 x 4 studs on exterior load bearing walls

Are finger jointed studs allowed in residential framing for exterior and interior load bearing walls. Couple this with using Thermo Ply for exterior sheathing seams like a very weak method of construction.

FJ studs are allowed and are considered dimensionally stable because the warping or crowning is done away with. Made by a reputable mfg they are fine, just not pretty.

R602.1.2 End-Jointed Lumber

Approved end-jointed lumber identified by a grade mark conforming to Section R602.1 shall be permitted to be used interchangeably with solid-sawn members of the same species and grade. End-jointed lumber used in an assembly required elsewhere in this code to have a fire-resistance rating shall have the designation “Heat Resistant Adhesive” or “HRA” included in its grade mark.

I have not done any framing with FJ studs, but given the quality of lumber anymore, these would probably be a welcome addition. Young guys framing today can not grasp the quality of lumber we readily had access to 30-40 years ago.

You mean when a 5/8" piece of CDX plywood lay nice and flat on the roof? LOL

Yes. You’ve been there!

Joke about it, we built a 800 sq ft great room addition to the end of my home in 1994. Cathedral ceiling, gluelams, 2x6 walls, 2x12 ceiling joints, 5/8" CDX on a 6/12 roof. That was probably the turning point for lumber quality, just seemed to take a different course soon after that, at least around here.

When I started framing in the late 70’s, the old timers used to call #2 lumber of that time period : crating lumber.

Even back in the early 80’s, we used FJ 2X4s. They are more consistent, straighter and not prone to warping after going into a wall. They are not suitable for horizontal applications, but they have excellent vertical strength as studs.
