    Jason,

    A Glulam looks like a beam made of plywood. It's not a stack of 2x4's.

    I can post pictures of both microlam/glulam beams the the floor trusses when I get home.

    Rob, check the website I posted for glu-lams. I have seen both--some that look like 6000-ply plywood, and some that look like a stack of 2x4s or 2x6s. The website I linked to shows the 2x4 type.

    Floor trusses are nice too because it is easy to run pipe abd electric through the open spaces. If you are going with solid wood I would have to lean toward doug fi. My house is mostly spruce and I think there is alot more movement with it. Doug fir is a better spec imho.
    I could cry for the time I've wasted, but thats a waste of time and tears.

    Well Jason - this proves you do learn something every day. I didn't know glulams were made that way. I wonder which is stronger - the stacked 2x4/6 variety or the ones I'm used to which are like plywood.

    I've attached a picture of the glulam beams supporting our addition and the floor trusses.

    The picture on the left appears to be a LVL (Laminated Veneer Lumber) beam.

    LVL is typically made by gluing up the veneers in a vertical fashion. GluLams are typically made by gluing the pieces horizontally.
