Floor Systems

Engineered floor systems come in two styles (floor trusses and I-joist) and offer the ability to span greater lengths without bearing walls when compared to standard dimensional lumber. Floor Trusses allow design and construction options not possible with standard lumber such as; hidden duct work and plumbing, optional end treatments and conditions.

Rim Board

Rim Board is used in conjunction with I Joists to create a stable and sturdy floor system. The Rim Board is placed at the end of the I Joists to secure them together. Rim Board should have the same depth as the I Joist you are installing.
