HoldRite® HydroFlame™ 50 is a smoke and acoustic sealant used to seal around penetrations in non-rated horizontal or vertical construction assemblies. Works in conjunction with and compliments HoldRite silencer™ series noise and vibration dampening systems. When properly installed, HydroFlame 50 will prevent the passage of smoke through penetration openings in non-rated assembles while also providing an excellent sound barrier by preventing the transfer of airborne sound and other vibrations from passing through the wall or floor/ceiling assembly.
