Southern yellow pine lumber prices went on an eight-week tear starting in mid-July, while tree farms stayed stuck in the Mississippi clay.
What's so weird about it? It can be any one of the three: Spruce, Fir, or Pine.Actually this weird thing of Spruce Pine Fir.
Yes I realize that Jeff, but generally an acronym (for example SYP or MDF) is the name of ONE species or material, not a choice of three. That's all that's weird. Just humor me... I couldn't resistWhat's so weird about it? It can be any one of the three: Spruce, Fir, or Pine.
Your partly right... Can be SPF - Spruce, Pine or Fir. However, if you read the article it says the big mill in canada shuttered for good. So I would expect to see a lot more pine in construction grade lumber, here in the USA, sooner rather than later.
In this case it's not an acronym. There is no choice-all three species are lumped together and you can't pick and choose at Lowe's or Home Depot. I wasn't being difficult and you didn't say what you thought was "weird" about it. Sorry.Yes I realize that Jeff, but generally an acronym (for example SYP or MDF) is the name of ONE species or material, not a choice of three. That's all that's weird. Just humor me...

Load tables give SYP a higher rating than SPF. It is definitely more dense with less deflection in equal spans with SYP, and usually the preferred lumber of choice when doing floor systems, trusses and LVL beams notwithstanding. Around CLT we've seen 7/16" OSB jump from ~$8.00/sheet to $29.50.
I have an 8'x16' tack room in my barn that is covered in 1/2" redwood plywood. Also there is a corner of the barn also covered in redwood plywood. This winter I'm going to take it all down and use it to build an 8'x16' Chicken & Turkey coop.Yes Southern Yellow Pine is much better framing material than the SPF. Usually SPF is the Coastal or Blue spruce, Various quick growing pines or white pine or varieties of hemlock fir or relatives. SPF is really good for interior wall construction. Never use it in outdoor applications.
On the West Coast we used Douglas Fir (Pseudotsuga menziesii). Not a true fir but a type of Larch which in many ways is superior to SYP. It twists less drying., less prone to splitting when nailing and has the highest Modulus of Elasticity (MOE). On the west coast it is usually cheaper than other woods, just depends when you get it. As of last week it was about 4 bucks for a 2x4x8. Here in Hawaii most of our framing wood is Borate treated, so here locally it is about 5.50 for a 2x4x8........ 2 years ago the same was 4 bucks for the same stud. This is why I have been buying so much hardwood ply. @ 5 bucks a sheet more than ACX, there is no real saving buying it.
The plywood they used in my house (built 45 years ago) is redwood-ply often wonder how much that would be today, if it is even made anymore.
Iirc the yellow pine takes the treatment better. I used to work with a west coast carpenter and he said that the pt out there was fir. The fir didn't soak up the treatment well and that's why the manufacturer punched all those little perforations into the faces of the lumber.I did a commercial building a few years back that had 2 x 6 x 12' exterior studs. The engineer specified spruce. The lumber supplier sent German Spruce, which appeared to be more dense than North American Spruce to the point that the framers thought it to be Kiln Dried Yellow Pine. Funny how it works that way sometimes. BTW, I have never seen anything other than SYP used in ACQ or CCA (now prohibited) treated applications unless it was a custom treatment, like oak flooring for a trailer.
