Techlite® Applied Ceiling Tiles in Obsidian™ are developed for architects, interior designers, and sound engineers seeking a streamlined approach to ceiling acoustics without the need for suspended grid systems. Manufactured from Basotect® Ecobalanced Melamine Foam, these tiles provide consistent sound absorption while maintaining a smooth, uninterrupted ceiling surface suited for offices, studios, and other acoustically sensitive interiors.
By adhering directly to the ceiling substrate, these tiles support a more integrated design language that aligns with modern architectural intent. For interior designers, this enables a monolithic ceiling appearance with minimal visual interruption. For architects, it allows for greater flexibility when coordinating with lighting and mechanical elements. For sound engineers, it delivers effective control of reflected sound, contributing to improved clarity and overall acoustic balance within the space.
In addition to acoustic performance, Techlite® Applied Ceiling Tiles support sustainability-focused design strategies. Basotect® Ecobalanced Melamine Foam contributes to responsible material selection and may assist in achieving LEED-related goals tied to Indoor Environmental Quality and Materials & Resources. The tiles are also Class A fire-rated per ASTM E84, ensuring compliance with interior fire safety requirements where performance and design must work together.
Obsidian™ Coloration & Visual CharacterObsidian™ 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.
