Acoustic and fire separation is critical between units in a mid-rise wood-frame buildings. If adequate separation is not provided, occupant safety and comfort can become compromised. The ROCKWOOL party wall system provides quality fire and sound transmission resistance, and can reduce labor and material costs associated with isolating building units.

ROCKWOOL COMFORTBATT® stud cavity insulation will not change shape or sag over time, ensuring a snug fit between the studs. This reduces airflow through party walls, thereby decreasing sound transmission between units and common areas. Stone wool also limits transmission of low-frequency impact noise (bass ranges) as it is manufactured out of dense, multi-directional fibers that effectively absorb sound waves.

ROXUL SAFETM 45 acts as a fire block between floors and units in combustible mid-rise buildings. As it is manufactured out of non-combustible stone wool, it will prevent the spread of smoke and fire. When used together, ROXUL SAFETM 45 and COMFORTBATT® stud cavity insulation form a fire-rated assembly, isolating neighboring units in the case of fire. This can provide

occupants with critical time to escape, even when the fire occurs in an adjacent unit.
