Roxul Safe™ 45 is a semi-rigid stone wool insulation board from Rockwool 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.
With this party wall system in place, required performance specs exceed code while vibration and sound transmission between party walls is reduced.
Roxul Safe™ 45 fire separation board complies with the fire-blocking National Building Code, is easy to install, and offers excellent water and moisture resistance.
