Non load bearing garage door header.

When framing in 16 centers a good rule of thumb when figuring material is one wall stud per foot of bottom plate. When in doubt use 2 by 12 inch headers. A header needs a full or king wall stud on each side of the opening extending from the bottom wall plate to. Between 4 and 5 feet the header should be built 2 inches wide and 8 inches long while a larger opening needs a header that is 2 by 12.

The beam they have specified now is 3 1 2 x 12 x 18 9. Section r502 5shares allowable girder and header spans. A header is to hold something up. The load that you need to resist is the horizontal force on the wall above the new door.

Measure the width of your door frame. For instance in the basement remodel all the doors have simple 2 4 framing around them. If your walls are non load bearing a single top plate is all that is required. The person doing the takeoff had interpreted my request for an 18 9 garage door header to the least expensive 20 long beam.

I d use a double 2x6 laid flat at the head of the opening. On previous projects i have been supplied a glu lam boise makes specifically for garage door headers that was 3 1 2 x 11 1 4 x 18 9. This is non bearing so you could use studs to create the space down from the roof or ceiling for the roll up door to roll up into. Non load bearing windows and doors do not require a structural header.

Most door frames that are 4 feet wide or less require a 2 by 6 header. This will usually give you the extra studs needs for corners and door openings.
