It might be of some interest though, metal studs are the same sizes as their wood stud counterparts. Welcome to our HSS - Rectangular and Square shapes free CAD downloads page Here youll find all Rectangular and Square shapes described by the AISC Steel shapes database (V14.1). Maybe when 3/8” lathe strips and an 1’8” of plaster were used but in today’s construction practices, it just ain’t so. Now, although some say that it is the same reasoning for studs, at the present time of drywall use, it’s not.
2x4 actual dimensions plus#
3/8” of mortar Plus the real block size brings the overall measurements up to an even 8”x 16”. With concrete block and brick, the difference is because of the proposed mortar measurements in between the blocks. Now, there is some dispute but some say that one of the reasons for the reduction is the same as the reason concrete blocks aren’t their “true” sizes. 2x4, but on the same card or another sticker it will also give the actual measurements in parenthesis.Īnd, although I have not calculated it in recent years, I do believe the amount of “board feet” that is charged for will be based on the actual finished measurements of the wood. Unlike going to a normal lumber yard, the mega DIY stores not only list what their wood products are e.g. If your project calls for precise measurements, be sure to check your lumber size before purchasing. For example, a 2 x 4 isn’t 2 inches by 4 inches. The actual measurements are the final size of your piece of lumber. This page is all about knowing the actual dimensions of commercial lumber sizes versus the nominal size used to refer to them. Molded lumber is often used for furniture parts, posts, and decks.

Generally these boards are used in their full dimensions. Walls are typically framed with studs 16 inches on center, rafters and joists usually the same, but sometimes 24. Drywall/Plasterboard - Various 4 foot varieties (4x8,10,12) and sometimes 5 foot. “In fact,” the suit says, Home Depot’s “dimensional lumber products all have materially smaller dimensions than those represented in its advertisements and product labeling.”Ī person suing a Home Depot or Lowe’s for shorting him on the lumber sizes would be hard pressed to make it stick. The nominal measurements are a board's size before it has been planed smooth (surfaced) on all four sides. Actual Dimensions: 1.5 x 3.5 x 8 (38.1mm x 88.9mm x 2.44m). In the states we have: Lumber - Comes most commonly in 2 inch (2x4,6,8,10,12,16) and 4 inch (4x4,4圆) varieties. It says that Home Depot sells “lumber products that were falsely advertised and labeled as having product dimensions that were not the actual dimensions of the products sold” and that “unbeknownst to consumers, the product dimensions advertised by are not the actual dimensions of the products being advertised.” "The suit says that Abramov was deceived by Home Depot and would have paid less had he known he was getting less lumber. "Abramov’s suit, filed in federal court in Illinois in April, says that he went to a Home Depot in Palatine, Illinois, in December to buy a four-by-four for a “small home improvement project.” When he got home, the suit says, he found out that the wood was only 3.5 inches by 3.5 inches." "In fact, federal-government standards define a two-by-four as measuring 1.5 inches by 3.5 inches.īut that hasn’t stopped Mikhail Abramov, of Illinois, from filing what he hopes will certified as a class-action lawsuit against Home Deport for selling undersized lumber." All the actual dimensions on charts and websites for lumber (not the inaccurate compared to final dimension nominal sizes) says they should be 8. " Everybody knows a two-by-four isn’t two inches by four inches." 27.Illinois man sues Home Depot because two-by-four wasn't two by four In which locations of the building do we need to provide insulation (Please explain in detail). For the following assembly, what do you recommend to increase overall R-value? A B R=8 R=1 Area=100ft? Area=30ft? 26. (A) Explain why exterior placement of insulation in the building envelope is preferable? (B) In which situation interior placement of insulation in the building envelope might be preferred? 25. air space 3-5/8-in.-thick brick veneerĢ4. on center 3-1/2-in.-thick fiberglass insulation 00012 Q 1/2-in.-thick plywood sheathing 2-in. 1/2-in.-thick gypsum board - 2 x 4 wood studs 16 in. (B) How would the results be different if you ignore the thermal bridging effect of studs? Use the p-value table provided in Chapter 5 presentation file. Hint: Calculate equivalent R-value for the insulation (area=3.5"x14”) and stud (area=1.5"x3.5in”), and then use the obtained R-value to calculate the overall R-value for the assembly).
Other members of the wall are shown in Figure below. Actual lumber sizes are pieces of lumber that are cut to standard. The spaces between the studs are filled with 3.5" thick fiberglass insulation. In reality, a 2×4 actual size measures 1-1/2 inches by 3-1/2 inches. (A) Determine the R-value of a wall consisting of 2x4 (actual dimensions 1.5”X 3.5) wood studs spaced 16" on center.
