Acoustical Products Made in USA.
Libraries and study environments are acoustically sensitive spaces designed to maintain extremely low background noise levels. Mechanical systems that radiate airborne sound into these areas compromise concentration and productivity. A primary contributor is mechanical duct breakout noise caused by airflow turbulence within supply and return systems.
Low-frequency sound transmission presents a unique challenge in library design. Because low-frequency energy travels efficiently through lightweight materials, untreated sheet metal ducts can easily radiate sound into quiet spaces. Standard fiberglass insulation improves thermal performance but does not significantly increase duct surface mass. As a result, ducts remain acoustically transparent to airborne transmission.
Architectural absorption treatments such as acoustic ceiling tiles and wall panels control reverberation within the room but do not prevent sound from radiating into the space. Effective library noise control strategies must focus on reducing breakout at the duct surface. Increasing mass and incorporating vibration damping are essential to achieving meaningful improvements in background noise levels.
The DuctaSil® B10Lag™ Pipe & Duct Barrier System improves acoustic insulation for ductwork by substantially increasing surface density. The mass-loaded vinyl barrier blocks airborne transmission across mid- and low-frequency ranges, while the insulation layer reduces vibratory energy transfer. Implementing advanced mechanical soundproofing systems ensures study environments maintain the quiet conditions necessary for academic focus and productivity.
