Correctly installed putty pads can create a compliant fire stop and smoke seal for these penetrations and can also improve acoustic performance. If there is an unsealed penetration or joint on a fire-rated boundary, the building will be non-compliant - this is where putty pads come in. The main aim of passive fire protection is to achieve fire compartmentation. This joint increases the ability for fire and smoke to enter and pass through the wall.
