Multi-Family Projects

Sound Transmission and Fire Resistance

Quiet Multi-Family Spaces

Sound control is important in lodging structures, multi-family apartments, condominium complexes, as well as Senior Living Facilities, or any building that includes dwelling units with shared walls. Shared walls can mean unwanted noise from the unit next door and shared corridors can also mean less privacy.

For newer or remodeled multi-family housing units, Building Codes throughout the United States require a measure of sound privacy between dwelling units. The International Building Code (IBS) specifies a minimum architectural design standard of privacy of 50 STC (Sound Transmission Class).

The Extreme Panel Solution

High stc ratings

Testing by an independent laboratory confirms that Extreme Panels reduce sound transmission, for a quieter indoor environment. Wall assemblies using the panels achieve sound transmission class ratings (STC) of up to 58-59 well above the STC 50 requirement for walls separating dwell units. Notably, these assemblies are also ASTM E119 hourly fire-related assemblies.  Extreme Panels provide builders and designers with energy efficiency, high STC ratings and hourly fire-rated assemblies in a framing system that the contractor and install very quickly. With today’s construction labor shortages, Extreme Panels offers an exceptional system with fewer labor requirements than traditional framing products.
