Tongue-and-grooved linear wood was traditionally toe-nailed to ceiling rafters. 9Wood has perfected the installation of linear wood in commercial wood ceilings, bringing the functional advantages of modern construction with it. Panelized or individual planks, open reveals or closed reveals, sound reflective or sound absorptive, solid or veneered, narrow or wide: a virtually limitless palette of designs are available to architects. A special example is our award winning "floor-on-a-ceiling" 2600 flush-joint linear style (a "they told us it couldn't be done" product).
