Using I-Joist Compatible Glulam

When the depth of the glulam matches the depth of the I-joists it is supporting, it is called an I-joist compatible glulam or IJC beam. IJC beams are supplied in depths of 9-1/2", 11-7/8", 14" and 16" to match the depths of I-joists used in residential construction. This allows ceilings to be framed flush with no need for extra furring out. These members are also supplied in widths of 3 1/2" and 5 1/2" to match conventional 2x4 and 2x6 wall framing.
