The Axiom Building Perimeter System from Armstrong is a pre-engineered solution to the transition between the ceiling plane and the interior of a building’s perimeter. The system provides an integrated approach to the inclusion of drapery pockets, window shades, air diffusers and changes in ceiling elevation at the perimeter. Compatible with both Armstrong acoustical and drywall grid systems, all elements interlock to form the finished perimeter. For more information, visitwww.armstrong.com/axiom.
