Laminated Beam For Bay Door Header...Thickness?

[REPO]

Ok, my plan is to use an engineered laminated beam for my 12' X 14' garage door. (Rather than 2x12's) i am stick building with 2x8's. Question is the thickness of the beam. Are they custom made for the dimension of lumber being used? Or are they a standard thicknesses, and I need to use 2 to get the thickness I need?

I know 2x8's are not common for wall building, but I live in a cold climate, and the more insulation the better!

Thanks in advance.

P.S. pictures are great too if you have something for me to reference!

I believe they are engineered in that you need an engineered drawing with them( just like engineered trusses)
s far as being the same thickness as your wall, you don't need a full beam to achieve that, you can use any blocking to achieve the thickness you need, after the beam is installed

So are you saying I can nail other dimensional lumber to the laminated beam to achieve the thickness I need?

yes, or styrofoam or virtually anything . it's just basically a spacer

My beam over a 16ft door is two 11.25x1.75 LVL beams nailed together per the manufacturer spec, plus a 2x12 and a 1/2 plywood shim to get it to 5.5 of thickness.

There we go.

I would be very (very)surprised to find any wall whereby a SINLGE 1.75lvl could span 16 ft....

Specs here...other mfgs have their own specs.

Or contact your full service lumber yard, say 'here is what I want to do, please spec the product I need and sell it to me'. Many will provide a canned 'report' on the application.

My 18' door is 3 LVLs headlocked together.

I'll bet with the 2x8"s you'll stuff that stud cavity!

What thickness of walls do you have?

What thickness of walls do you have?

2x6, and it came 1/2 short IIRC

Whats the load? Perhaps 2-2x8s would work, but you also need to worry about deflections.
