Acoustic Foam vs Mineral Wool vs Perforated Panels: Performance, Cost, and When to Use Each
Three acoustic absorber types dominate building design: foam (cheap, poor bass), mineral wool (all-rounder, fire-safe), and perforated panels (aesthetic, tunable). Here is a head-to-head comparison with octave-band absorption data, installed costs, fire ratings, and the specific room types where each excels.
