Cavity barriers are passive fire protection products made of fire-resistant materials, they are used to seal cavities and therefore, prevent the spread of flames and smoke through spaces within the cavities of the building.
This process slows the spread of a fire, increasing the time people are able to evacuate the building and allowing the fire fighters to get the fire under control on a faster time frame, thus reducing the damage to the building.
Nullifire’s selection of closed and open state cavity barriers are tested to many construction materials. Offering a huge selection of high performance results, utilising different substrates, different insulation types and a variety of cavity widths and air gaps, the reactive material within Nullifire’s ventilated cavity products meets and exceeds the requirements of ASFP TGD19.
