What is the difference between rotary and textile fiber glass insulation?
The two most common processes used in manufacturing fiber glass insulation are rotary and textile. They show a nominal difference in performance properties on paper, but their installed performance characteristics are nearly equivalent. Textile fibers perform well in thermal and acoustical applications and provide a strong and durable insulation product. Rotary fibers provide incremental R-value (thermal resistance) and noise reduction coefficient (NRC)-value improvement over textile.
