I want to free span a room with a beam in the attic, on top

Customer Question

I want to free span a room with a beam in the attic, on top of ceiling joists. The roof is raftered 2x6, the ceiling rafters are 2x6 also, 25' long. The span would be 21' clear, and the load is just the ceiling joists and drywall/ insulation. There is no acess for storage. The beam can be slid in thru end wall in garage space.

Is there any more information you need from me?

I will. I'm driving right now. Can I get back to you in a couple hours?

Expert:  StructuralEng replied 11 months ago.

Will there be any flooring in the attic? Plywood?

Customer: replied 11 months ago.
Sorry if duplicate, but no floor of any sort. No storage, just insulation.

5.125" x 13.5" pressure treated glulam 24F-V4

Customer: replied 11 months ago.
Why pressure treated?
Expert:  StructuralEng replied 11 months ago.

An attic space has large temperature and humidity swings. It's not required, but is advisable.

Ok, thank you.

No problem. I'm happy to help. Good luck with your project.
