FJP Studs?


Anybody using them?

Likes?
dislikes?
comments?

One builder I work for started using Finger Joint studs.
I'm not sure what I think of them.

On first thought they seem to be half assed.
From an assembly perspective they do seem more straight.

Up here In a lift of FJP 2x6 9' precuts I can usually use 90 -95%
On standard spruce "premium studs" It's not unusual to cull 30%


The fj studs are more expensive than premium studs too.




One thing for sure,
VERTICAL USE ONLY.

If they are from Ainsworth...

We used them all the time when I lived in Seattle. For the most part, nice and straight. Sometimes the glue joint doesn't hold and one or two break at the glue joint. Definitely vertical use only. My house? Probably not.

I think they are nice for 9' and 10' walls.

Re: FJP Studs?


Same here, all we use for 9' and 10' walls.

They are straighter, resist warping better, and are actually made from a better grade than a premium stud because of the requirements for strength at the joints.

And as Framerman mentioned, you do run across a couple that just fall apart at a joint. So far we usually only get a couple of bad ones per house, so that would put us at 99%. And then those bad ones get used anyway for cripples, etc.

I usually hear that too, people claim they are straighter and that's why they are used. However, the framing company I worked for, BMC, used the worst kind you can buy. They were not straighter, they were far worse than non-finger jointed studs. we had to shim and shave 150 to 200 studs per house, all finger jointed studs.

It depends how the lumber company purchases their materials. BMC West would look at prices when they purchased from mills. Whichever was cheapest, that's what they would buy, so that's what they got was cheap.

FJP- Finger Jointed Pine. I don't think I'd use them for load bearing purposes unless they were made out of fir.

Its been quite a few years since I have dealt with BMC West.

But I would have had them take them back and bring me good ones. No way I would take the time to do all that.

We have been dealing with Probuild formerly Lumbermens for quite a few years now, and Gray Lumber in Tacoma since I started 30+ years ago. And I have had very few problems like that with either of them. And if I do they are prompt and will do something about it.

Re: FJP Studs?


I worked on a few jobs in Seattle where they were used. Onsite they never stayed dry and I definitely saw some problems when it got below freezing. Lots of glue joints falling apart.

They were nice and straight for tall walls, but I do my best to keep them dry even after the walls are up if I were going to use them.

Re: FJP Studs?


I have not used them in a while 10 years?

The only place I would use them
is on non load bearing walls 9' or shorter(they would have to be less expensive than a standard stud to even consider it)

The problem is the glue
when I build a house the frame should last a couple hundred years
If maintained properly

How long will the glue last 10 yrs 100 yrs?

I've seen very few homes built with finger joint studs, and they are less expensive than premium studs here. I'm no framer, but I see no reason not to use them for non-load bearing.

200 years ago when homes were being built with first cut, full dimensional lumber, I'd expect a well framed house to last a few centuries. Today I doubt even the most well framed house, built with second cut lumber would last more than one century. Just my 2 cents..

Just to clarify, I'm not bustin' on you or anything. The pine out west is different than what we get here. Not quite sure what it is, but we framed many homes with pine whether it was FJ or not. I think it may be lodgepole pine, but not quite 100% sure.

Structurally and stability wise, much better than the white pine we get here.

Re: FJP Studs?


We actually had were using then about 2yrs ago, in Ontario and them were deemed not fit for load points so we actually had fj stud's with actual 4x4 or 6x6 post's for all loads. As was said in earlier posts not in my house.

If in 2120, you find an average home built in 2010, that is still structurally sound, pm me and I will acknowledge your greater foresight.

OSB that all these houses are built with won't last that long. houses will have to get resheathed, rebuilt etc. not even sure plywood will last more than a century. glad i don't use OSB.

They didn't have good ones. They were a lumber supplier and a framing company so they sold the lumber to themselves. Yeah, they weren't smart enough to fix the problem, sure enough they went bankrupt.

Re: FJP Studs?


I have not seen FJ studs in 10-12 years in Atlanta. When they were first introduced, Georgia Pacific invited a group of us to there facility here and they showed test after test on the strength of FJ vs standard studs. The FJ studs won every time!

I was very impressed and we used them for a while but then the suppliers began phasing them out. I asked why and could never get a straight answer. Makes you wonder???
