The combination of the panel thickness and the supporting beam thickness generally rules them out for use as interior floors, but they are often used in floors which are part of the insulation envelope. Sometimes the best use of panels in the insulation envelope is as ceiling panels. The easiest way to install ceiling panels is with trusses, with the panels hung from the bottom chord of the truss prior to finished ceiling installation. The standard connection detail for panels at the ridge utilizes a laminated, beveled ridge double spline over a beveled ridge plate over a ridge beam. Roof Panels are used most for cathedral ceilings, and are unsurpassed in this regard.
Drop ceilings are also possible, but usually more expensive than other alternatives.
Walls Panels are often used for walls. In high wind load areas or seismic zones thicker panels may be necessary. Standard wall connection, door and window connections, spline connection options and plate connections follow.
