LVLs: A Strong Backbone for Floor Framing
Laminated-veneer lumber lets you assemble big beams without a big crew
Laminated-veneer lumber (LVL) combines the versatility of sawn lumber with the strength of engineered beams, according to John Spier. In this article, Spier talks about how to build up center carrying beams and two different ways they can support a floor frame (flush beam or dropped beam). A sidebar illustrates the different engineered beam choices (LVL, LSL, PSL and GluLam) in addition to the old standbys (sawn lumber and steel) to give readers a ”best-use” application for each type. A photo sidebar shows how to support the beam ends and middle.
