Techlite® Double Mini Wave Panels in Obsidian™ provide a dimensional acoustic solution tailored for architects, interior designers, and sound engineers seeking both performance and visual depth. Fabricated from Basotect® Ecobalanced Melamine Foam, these panels are designed to reduce mid- and high-frequency reflections while introducing a subtle patterned surface that enhances spatial character in studios, offices, and specialty interiors.

The dual-wave geometry creates a consistent, repeating profile that supports effective sound diffusion and absorption across treated surfaces. For sound engineers, this translates to improved clarity and reduced flutter echo. For architects, it offers a modular system that integrates cleanly across walls and ceilings. For interior designers, the panel introduces texture and shadow play without overwhelming the overall composition, allowing it to work seamlessly within modern and minimal design schemes.

In addition to acoustic performance, Techlite® Double Mini Wave Panels contribute to sustainable design strategies. Basotect® Ecobalanced Melamine Foam supports environmentally conscious material selection and may assist in achieving LEED-related goals tied to Indoor Environmental Quality and responsible sourcing. The panels are also Class A fire-rated per ASTM E84, meeting key safety requirements for interior applications where performance and compliance must align.

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.

Absorption results tested in accordance to ASTM C 423-09a

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.
