Product Details
The FF102/50 Fire Blocks are rigid, high expansion intumescent strips encased in aluminum foil. The FF102/50 can be mechanically fixed both horizontally and vertically within concealed cavities and air gaps of up to 2″. For larger cavities please refer to our FF102/50Plus products.
The FF102/50 enables high-performance rainscreen walls while simultaneously delivering exceptional fireblocking. The open space between the FF102/50 and cladding allows for airflow and moisture dissipation while in a fire, the intumescent material rapidly expands to seal off the cavity and prevent the spread of flames and heat.
The products have undergone extensive fire testing, including NFPA285 at Intertek and Underwriter Laboratories (UL), and are a NYC OTCR/DOB approved material in accordance with the 2022 NYC Building Code Section 718.2.1 (item #8) when required in concealed spaces of exterior wall coverings as specified in accordance with BC 718.2.6.1.
In addition, the intumescent material was tested according to ASTM E84 (UL 723) to measure its surface burning characteristics and achieved a flame spread index of 0 (zero) and a smoke developed value of 0 (zero).
FF102/50 intumescent strips are used as fireblocking at slab lines, fire blocks around windows and as fire blocks at changes in occupancy (horizontally and/or vertically).
