Brief illustrates how design of insulated precast walls and connections provides effective noise reduction
AltusGroup, a partnership of 21 innovation-focused North American precasters, has published a technical brief explaining the acoustic performance of CarbonCast High Performance Insulated Wall Panels and how they can be used to reduce the amount of outside sound reaching the receiver.
The brief discusses the Sound Transmission Class (STC) rating system, which correlates with better performance of sound insulation. Precast concrete, specifically CarbonCast technology, is designed to close noise gaps and create an impenetrable barrier for outside noise, increasing STC ratings.
The two-page PDF highlights the formation of noise gaps. CarbonCast walls can be produced in large widths and full height modules with caulking and insulation at the joints, lowering the possibility of leaks or flanking as compared to steel or wood structures that might have multiple joints and connections.
Several other AltusGroup technical briefs are available on topics including acoustic properties, insulation, rain barriers and rain screens, and thermal efficiency.
