Armstrong Ceilings CORTEGA Acoustic Mineral Fiber Ceiling Panels deliver standard sound absorption and noise reduction coefficients suitable for offices, classrooms, corridors, and other interior spaces where acoustic control is necessary. Their high light reflectance helps improve indoor brightness, potentially reducing lighting costs. CORTEGA panels are available in several sizes and thicknesses, making them a practical option for both new construction and retrofit projects where consistent acoustical value and ease of maintenance are priorities.
