Access on both sides of a wall is usually needed to install compliant firestop systems. However, this isn’t always possible—especially in apartments where one side of a fire-rated wall may be inaccessible due to kitchens or other restricted areas.
At FIREFLY, we recognise these real-world challenges and have tested several firestopping systems installed from one side only. Our results show that certain single-sided systems can still provide effective fire resistance and meet compliance requirements.
These solutions also cause less disruption, allowing residents to enjoy their space with minimal disturbance.
