You did a really great job explaining your topic, particularly how to go to the code books to make determinations of header requirements based on the tables in those sources. I'm new to construction, though, and I got a bit lost at the end with some of the terminology for the framing members. I guess that's to be expected, though, when there are multiple names for the same things. Anyway, keep up the good work, sir.
I always just use the 1-2-3 method for framing out doors. Goes like this : 1 is the actual door size, plus 2 inches is the rough opening, plus 3 inches is the header size. 1-2-3. Never fails.
Thanks for the video. I'm confused as to how "building width" should be applied to one side of a load bearing internal stairwell for purposes of span charts. I want to open up about a 4 foot section of load bearing wall on one side of the stairwell as part of a basement finish to install a banister. The house is a 2-story home with a 2x6 load bearing wall running down the middle and along the stairwell. The side I want to open up also is load bearing, but only for those joists that cannot pass through the stairwell to be supported by the other wall. The total "building width" is about 28', but the wall I want to open is only supporting joists that span about 12', while the main load bearing wall is supporting joists from both sides (the full 28') over the portion of the basement past the stairwell. My instinct is that to apply the 28' building width to both sides of stairwell doesn't make sense, as the continuous main load bearing wall seems to be supporting a lot more load than the other wall which only runs on the other side of the stairwell . Would I use a building width of 12' for purposes of the table for the wall which is only supporting joists spanning that distance?
Good topic to address. Window openings are kinda a second thought on so many construction related channels. Lots of talk about the window itself and flashing but not enough on addressing build out and load factors. Thx
Very helpful video. Question: we are replacing the original windows with new construction windows in our 1930 house in CA. We are planning to change size of 3 windows, and in advance of ordering the windows we opened the walls above the 3 windows to see where the headers are located. Probably not surprisingly, the headers are not to code - there are 2 2x4s laid flat (old redwood: 2" x 4") above each window. We fear that we will need to install new headers on all of the 22 windows. Do you think this must be done?
I am in California I am building my own home I have a question about the headers can I build the headers up or do I have to use a solid piece of lumber for 2 by 6 exterior
make a video explaining the Simpson HH4 and HH6 header hangers. I'm surprised there's not really any content talking about them. I'm about to frame a Tiny House and decided to use the HH6 header hangers since I'm framing with 2x6s.
Is there any way to figure out the size of beam you would need for a patio span? I have a section of patio that currently has 5 columns. I'm looking into changing the beams and columns so there are only 3 columns. Thanks!
I will be making a video on that later, but you might be able to use the same chart I got the information I refer to in the video. For example a girder is another name for a beam.
What if I have windows on the first floor of a two storey house, but the roof framing is parallel? The lintel would not be carrying the same amount of roof load as if the roof was perpendicular. What table should I use for this?
Good Job! Most videos I watch the are very wordy and not to the point, not you, great job! I will be using Strong tie 6" HH brackets for 90% of my openings, since 3' is around average sized openings, the headers aren't very big. My 24" windows almost don't require a header, so I am interested in how to fill the HH bracket to hold a single or double 2X? Box it? Hope you do a video on it before I need to info. Thank you so much.
How do you measure (or interpolate) "building width" or "span carried" for selecting a header for an interior load bearing wall that only carries roof and ceiling loads? neither TABLE R602.7(1) or TABLE R602.7(2) seem to have the case needed. Also, question 2: for a header that is on an exterior load bearing exterior wall that supports roof, ceiling, and has a load bearing wall somewhere near the center of the whole building (that i assume holds about half of the ceiling load)? or should I assume building width is the whole building width not counting middle interior load bearing wall? and why? thanks
You can not use interpolation in this table. What you are asking is assigning a "tributary load". 30 ft building width, the center wall at 15 ft load. so the left wall takes 7.5 ft load, the center wall takes 15 ft load and the right wall takes 7.5 ft load,. You are correct the interior center wall takes 1/2 the load no matter if it is off-center. Yes, it is the total overall load. The center wall accounts for 1/2 the load, and the exterior walls each carry 1/4 of the load. Now if the center wall is only carrying the ceiling joists and not the roof members. we can unload the wall at least 45 psf to 15 psf. This becomes an engineering solution and not an RC prescriptive table method.
So how does one figure header size when the width of the building exceeds 36 ft. It’s not covered in the chartsz I see where the charts can be interpolated lesser sizes, but no mention stepping up to larger. I’m working with a is 38 ft width.
Hi Greg, I have a non load bearing wall, my contractor used 4 by 4 inch post on each end of the beam which is 4 inch by 12 inch by 12 feet, open 12 ft. Both 4 by 4 posts are attached to a 2 by 4 inch by 10 ft stud. Do you see any concerns? Thank you. It is 1 story house with a basement.
2:20. I don't think that's correct. On the off side (non-bearing) from roof trusses, no header is needed. Per 2015 IRC, “Load-bearing headers are not required in interior or exterior nonbearing walls. A single flat 2x4 may be used for openings up to 8 feet in width” (R602.7.4).
you need to review how to make the headers for a 2x6 wall, your explanation was not what i learned, that its 2x then half inch ply or osb then 2x then another half inch ply or osb then one more 2x.
I DON'T GET WHY THE WRITERS OF THE BOOK USE "A-B x C" format instead of "(A) B x C" OR "(A) BxC" for the "SIZE" IT'S INCREDIBLY MISLEADING, and to make things worse, on the same table, the 'span' column has values in "A-B" FORMAT. So they are using the same format for two different things. Example: 1-2 x 8 this is supposed to be read as "one two by 8" but the format reads as 1'-2" x 8" ??? (which doesn't make any sense). Also name of 'size' column should be 'amount and size', since we are talking about multiple pieces and different size pieces. Annoying as h

Thank you SO much for explaining the chart! I had lots of questions about it and you managed to answer all of them in your thorough explanation! :)
You are so welcome!

That formula works great for the length of header.

Thank you gregvan. I am putting in headers tomorrow morning in a garage.
Sounds great!
Thank you! I literally just bought a window just an hour before you released this video.
Glad I could help!

I don't have a table for that, but some builders use the suggested header sizes in charts for those designs.

Email me a picture of your problem or provide more details. I can't tell why you need them filled.
Using 2x12s everywhere keeps the tops at the same height, usually looking better outside.
Good Point.

I don't have access to the charts you're requesting, but if you find them, let us know.

I'm guessing any beams or headers that long will require consulting an engineer.
Excellent video
Thanks
Which countries can use the international building codes book ??
Im guessing the USA does since you are from there.
Isn't he Australian?
@@hiiamhi.23 doesn't sound like it and from watching his other videos he designs like he is an American
It's used here by some in the United States.
Hi Greg,

Room sized headers for construction
That might be an engineered beam and might not be on this list.
