ROXUL SAFE™ 45 is a semi-rigid stone wool insulation board that is specifically engineered as a fire-blocking material for concealed spaces of multi-unit residential buildings.

Using ROXUL SAFE™ 45 with our ROCKWOOL batt insulation creates a high-density “party” wall system that improves sound dampening and fire performance. It also reduces the time, labor and material costs usually associated with adding a double layer of gypsum over the wall studs.
