Multifamily Construction: Meeting IBC Fire & Acoustic Code with Stone Wool

Navigating the Complexities of Multifamily Building Codes

Constructing apartments, condominiums, and townhomes requires strict adherence to the International Building Code (IBC), particularly concerning fire safety and acoustic privacy between units (party walls).

The ROCKWOOL AFB Solution

To meet 1-hour and 2-hour fire-rated assembly requirements, contractors rely on ROCKWOOL AFB® (Acoustical Fire Batt). Engineered specifically for steel stud commercial construction, AFB is non-combustible and can withstand temperatures exceeding 2,150°F.

Simultaneously, AFB provides the dense mass required to meet the high STC (Sound Transmission Class) ratings demanded by luxury multifamily developers, ensuring that tenants do not hear their neighbors. When paired with Resilmount® Sound Isolation Clips, developers can achieve premium acoustic isolation and bulletproof fire code compliance in a single assembly.
