Linear Open Series 3 (LO3) is panelized to offer a faster and more economical installation. LO3 solid or veneer panels would be supplied in 8' or 10' lengths. Panels are factory assembled using flat black wood backers. Standard panels are 1' or 2' wide and planks are 3/4" thick. Standard reveal is 3⁄4" (other reveal widths available upon request). The reveal allows the acoustical treatment to absorb sound waves. Optional black fiber-felt strip can be factory installed. Ceiling applications are suspended from Armstrong® Prelude® XL® grid. Wall applications attach using sheathing or furring strips. The system is fully accessible. Access panels or doors are optional in areas where frequent access above the ceiling is required.
