What is 5/4 lumber? - Fine Homebuilding
2008年4月20日 · 5/4 to me usually means anything from about 1" to 1 1/8" thick. I've seen treated wood anywhere from 1" to 1 1/4" thick, depends on the dryness. so a 5/4" X 6" will be closer to 1" X 5 1/2" but the 8' should still be 8'. If I was buying 5/4" finished wood I'd expect it to be a consistent 1". Doug

1-5/8 thick 2x4 - Fine Homebuilding
2007年12月15日 · What year did dimensional lumber change from 1-5/8 thick to 1-1/2″? Pretty sure same year a 2×8 went from 7-1/2″ to 7-1/4 inch, etc. 1954?, could not find a good web reference for the date, think Weyerhauser was the instigator of the reduction, recall a pop. science article about relative strengths, but cannot find it.
How to Install Deck-Stair Treads - Fine Homebuilding
Common deck-stair tread configurations include two pieces of 5/4×6 or 2×6 lumber, three pieces of 5/4×4 or 2×4 lumber, or a single piece of 2×12 lumber.

LVL equivalent to 2x12? - Fine Homebuilding
2006年9月25日 · Went by Lowes and called RP. The Lowes dude quoted me $5.46/ft, but while he was saying it was 3.5x9.5, I suspect it was really 1-3/4", because he had trouble looking the price up and kept going back to the book. RP dude said 1-3/4"x9-1/2" for $4.50/ft. So regular lumber 2x12x12' = $12.68 (Lowes) LVL = $54- 65.52.
Dimensional shrinkage of pressure treated lumber.
2019年12月3日 · On a side note, but hopefully helpful to someone else here, M.W. has a video on youtube where they suggest separating the deck lumber into three piles. Those that measure 7 1/2", those that measure 7 3/8", and those that measure 7 1/4". After making piles of each, install them together working from 1/2" to 1/4".
r-19 insulation in 2x4 space - Fine Homebuilding
2004年12月6日 · Kyle,I recall that the reduction in r-value for a R-19 batt fit into a modern 2x4 wall yields R-15. Compressing the FG gives higher R per inch of thickness, up to a point. You might get R-15.5+ in your 4" cavity.I still use FG on little jobs, because convenient. However, most everything else is better one way or another.
Wood beam equivilant in steel? - Fine Homebuilding
2006年10月3日 · With this figure, I would multiply it by 4, and find the equivalent wide flange steel member that could handle the same. That would be nice and conservative, as the LVL has a better capacity for load than most #1 structural timber. To size the steel, you'll need something like SpanCalc, or do it the old fashioned way.
Odd length and 2X5 lumber - Fine Homebuilding
2002年4月17日 · It all used to be 2" by 4" (Or whatever) at one point in time. But as lumber got more scarce and more expensive, they started looking at ways to reduce costs. Some mills started out giving you 2" by 4" less the thickness of the saw blade. Since not all saws and mills were the same, lumber wasn't always consistent sizes.
How to Calculate Deck Cantilevers - Fine Homebuilding
Needless to say, there’s a lot more to joists than simply choosing the right lumber. But that’s still the best place to start. Dried lumber makes building easier. Most decks are framed with pressure-treated dimensional lumber. The pressure-treating process leaves lumber wet; the moisture content may exceed 50%.
