Armstrong’s AXIOM® line includes trim and transitions for a variety of ceiling needs. CBSI carries a wide variety of Armstrong AXIOM ceiling trim products for construction pros in the Mid-Atlantic region and beyond, including:

Armstrong AXIOM® Classic

This extruded aluminum perimeter trim gives a custom, decorative touch to drywall and suspended panels. Typically used for entry accent points, open corridors, “floating” clouds, and stepped soffits, it can be used with Armstrong suspension systems and Drywall Grid Systems.

Armstrong AXIOM® Knife Edge

Designed as an alternative to 90-degree vertical trims. Available in two versions, which allows for use with acoustical lay-in panels, Tegular panels, drywall, and vector edges. Standard 90° corners are factory bonded and can be used with Armstrong suspension systems or Drywall Grid Systems.

Armstrong AXIOM® Vector

Made of extruded aluminum designed to work seamlessly with Armstrong Vector ceiling panels. Creates a ¼” recess matching the reveal of the Vector panels, allowing the edges to be preserved. Typically used in offices, retail and educational spaces, hotels, and healthcare settings.

Armstrong AXIOM® for Interlude

Designed exclusively for use with the Interlude XL HRC suspension system. Available in 2”, 4” or 6”, with standard 90° bonded corners. Useful in a variety of settings including office, retail, and educational settings, conference rooms, healthcare, churches, transportation settings, and hotels.

Armstrong AXIOM® Transitions

Available in three versions: Acoustical-to-Drywall (straight or curved), Vector (straight, but only for use with Vector panels), or Elevation Change (to accommodate transitions between ceiling tile panels, between walls and ceilings, or between walls). Part of Armstrong’s Sustain™ portfolio - one of their most sustainable choices for building materials.

Armstrong AXIOM® Soft Edge

Available in three profiles: Ripple, Soft Corner, and Convex. Its ¼” reveal along the trim can be used in straight or curved applications. Designed for use with acoustical clouds and available in a variety of factory-applied finishes.

Armstrong AXIOM® Profiled

Pre-engineered and available in four profiles: Convex, Concave, Cove, and Crown. Decorative trim with beaded edges that can integrate with all trim profiles. Available in custom colors to coordinate with Armstrong ceiling and suspension systems.

Offered in five molding profiles, in both straight and curved. Made of extruded aluminum with a factory-applied finish, and compatible with Armstrong ceiling and suspension systems.
