Re: Window And Door Header Question


It seems most guys use 2 x 10's and sandwich a 1/2" plywood in between. Then they nail a 2 x 4 to the bottom. Does this sound accurate to you guys?
Also,is it necessary to nail a 2 x 4 to the bottom? Whats th reason.
Thanks everyone

The 2x4 on the bottom of a 2x10 header sets the proper height of modern day door openings, for the most part 83" on a 6/8 door height. (Depending on the width of a given 2x10, could leave up to 83 3/8".)

Many entry doors require a RO of 82.5", but it's a good idea to put 1/2" plywood under the sill pan for a carpet shim.

A small opening doesn't require such a header, but for continuity of height, it generally is the case. I've had situations with limited room for header on 2' width that were designed with the top plate removed, leaving only the double plate above a 2x4 header. I've also had situations where their was no header in the wall, just the two plates and the box was doubled in the floor system above with the joists hung from that.

It depends on the wall thickness. However, the bottom plate almost always gets cut out during a door installation. I have done stepover door sills onto waterproof decks with parapet walls, although I prefer to step down onto the deck without raising the floor height with sleepers. It depends on the design of the building.

Re: Window And Door Header Question


typically a bottom plate of a patio door or entry do will be a 2 x 6 .
this is especially common with 2 x 4 framing.

Why? Because it is how I was taught and faster for me then other methods.

Another guy I worked for separated his 2x10's insulated with fiberglass between them, then put on the bottom 2x6.
For doors I usually nail the 2x10 tight together and put the jacks right under it, and when the bottom plate gets cut out for the door, I nail that cut out up under the header. Gap to the inside for insulation.

As I said, spacing the header plys with plywood will get your inspection failed around here.

Also, headers right above the opening, not under the top plate.

As per Shane...
Gap to the inside for insulation, so the Inspector can see it.
Use styrofoam on them to raise the R-value. Typically 2 x 6 framing here. R-22 in the walls is the target.
If you leave the gap to the outside, the Inspector can't confirm that it is insulated.

Why? I have seen it both ways.
Header at top with cripples below, or header at bottom with cripples above (I do the latter)

Tomstrubles and yes, drywall should be nailed to them.

That part was not a code requirement, just the way I do it.

Re: Window And Door Header Question


Not to add fuel to the fire but since I started back in 1990 I have never framed a house with 2 x 4 always 2 x 6.

The builder I worked for always used a three ply header, pluse plywood fillers. It was typical for us to use the form material from the footings for the headers.

This was usually 2 x8 or 2 x 10 material, I as the low man had to pull all the nails scrape the concrete from the forms and stack everything ready for cutting.

We would install headers at the prescribed height just above the window or door heights.

Over the years on my own and after one too many customer that wanted to change the window height I decided to install all of my headers under the plate and build down to the proper height. I also lost the plywood and would fill with rigid foam to the interior. I found that the sandwich always stood proud of the studs.

I subbed the framing on my last major project and the framers used a spaced header just above the windows. I had my spray foam guy fill the cavity with foam.
Hope this helps Chad

Re: Window And Door Header Question


Our codes allow us to put the header on the jacks or all the way up with crips under. I prefer it at the proper height with crips above. Like Rizz said it just feels stiffer for the door. Picture a long garage door header all the way up with long crips and a 16" long plate under that. Seems more stable with the header right there where the door is. Many times on the interior walls I will put the header all the way up to allow for people to decide later if its a 6'8 door, 7'0 door, or maybe even an arch. Much easier to adjust if the header is up. When in doubt, Push it up!

We like to use 3/8 plywood as a spacer. We all know how the 2x10 and 2x12 likes to cup and swell. I have yet to hear the drywallers or the finish carpenters complain because the jambs were proud of the drywall.

One drywaller I worked with would not fasten to the header, just the 2x6 across the bottom of it. That way if the header shrunk or twisted there were no drywall screws to pop.
