HVG Facades offer a wide range of firestop options to address slab edge protection in an external facade and curtain wall applications, including both cavity barriers and perimeter barriers. 

The cavity barriers used behind external facades allow the cavity to remain ventilated under normal conditions. In the unlikely event of fire, intumescent strip on the barrier is activated at a certain temperature which then begins to close off the cavity space. This prevents fire, smoke and gases from spreading to the floors above.

The cavity barriers can be used both horizontally and vertically. 

The perimeter barriers prevent the spread of fire, smoke and gases between the slab edge and the curtain wall or spandrel. The perimeter barriers can be used both horizontally and vertically.
