The TECHLITE® Designer Rails Acoustic Panel in Obsidian™ delivers a disciplined linear aesthetic paired with measurable acoustic control. Its elongated, rail-inspired geometry establishes directionality across ceilings and walls, guiding the eye while simultaneously reducing reverberation. For architects shaping spatial identity, interior designers defining material continuity, and sound engineers managing clarity and decay times, this system balances visual order with acoustic function.

Manufactured utilizing Basotect® Ecobalanced Melamine Foam, the panel offers highly effective broadband absorption in a lightweight, structurally stable form. The open-cell composition supports speech intelligibility, mitigates echo buildup, and improves overall room balance in corporate environments, performance spaces, educational facilities, and collaborative interiors. The material achieves Class A fire-rated performance per ASTM E 84, ensuring code-aligned specification for interior applications.

In addition to acoustic and life-safety performance, TECHLITE® Designer Rails contribute to sustainable project goals. Basotect® Ecobalanced Melamine Foam is produced through a reduced-carbon approach and may assist project teams pursuing LEED-related credits, including responsible material sourcing and low-emitting interior components. This alignment of environmental responsibility and acoustic precision supports today’s performance-driven design standards.

Obsidian™ Coloration & Visual Character

Obsidian™ is a deep, dark charcoal acoustic foam with subtle blue undertones. Depending on lighting conditions, it can range from a rich charcoal gray to a dark navy hue—and when installed in high ceilings or low-light environments, it presents as visually black.

The result is an acoustic material that integrates seamlessly into contemporary architecture while delivering the performance Techlite® is known for. For applications requiring an ultimate, rich black appearance, Obsidian panels may be coated utilizing Techlite®’s proprietary paint system.

Sound Absorption

Sound Absorption Testing to ASTM Standard C423-09a indicates a better than 90% absorption coefficient at a frequency of 2000 Hz when using 2” thick TechLite® foam. Combined with a Class A fire rating, excellent thermal insulating value, its light weight and low toxicity, TechLite® is an excellent choice for your application.
