I would not build anything with a 14 foot span. You'll get eventual sag
in the middle no matter what you use, unless it's a steel girder. Use a
center post. Seven feet is easy to span and much stronger.

Seriously? There are tens of thousands of homes that span 16, 18, 20
feet and have no supports on some beams.


Good point, a typical double garage door is what, 16-18'?

Saw one, a concrete poured beam (lentil?) in a house that broke in the
center and sagged over the garage door. Seemed odd to me as it was a
first.

The roof trusses dropped a few inches -- causing further roof damage.

Strange to say the least.
