LVL Beam Strength???

I'm taking out a load bearing wall but putting up a support beam first. The span is a little over 16' supporting ceiling joists and some roof trusses. I went to my local yard and they said all I needed was one LVL beam. I'd never heard of them before so looked it up. The dimensions are 12"X2"x18'. 2"? Really? That's all the wider it needs to be? Not 3 or 4 of them sandwiched together? I read that LVL beams were stronger than traditional beams but I'm old and can't get the image of something less than 8" wide doing the job.

It all depends on the load you are putting on it. LVL are stronger than traditional lumber but I too have never seen just a single LVL used. Usually they are double or triples. I would confirm that the proper engineering was done to size the beam you need. There are span charts on most manufacturer's websites you can check.

You really should not use a forum to make decisions this critical, that is what architects and structural engineers are for!

Thanks Marq1. I had no idea professionals should be consulted.

In my area any time a engineered lumber beam is used it must be accompanied with signed and stamped documentation from the Engineer. Without the Engineer's seal and signature my inspectors will not pass it.
