Product Details
Modern constructions often require external cladding and rain screens to be held away from the building structure to allow ventilation and improve the building energy efficiency. This resulting cavity creates a serious fire protection threat to structures and people. The void acts like an open chimney and allows the fire to spread quickly both vertically and horizontally around the building.
The VFB Plus Ventilated Fire Barrier is a ‘Open State’ Cavity Fire Barrier system for ventilated cavities of up to 19.6″ (500mm) which employs a high expansion intumescent seal fixed to TENMAT High Density Mineral Wool. The product has undergone extensive fire testing, including NFPA285 and is suitable for use within a wide range of construction types, enabling the versatile system to be specified with confidence and provide the installer with a simple, time saving and site friendly solution.
The VFB Plus Ventilated Fire Barrier consists of a high expansion intumescent strip fixed to TENMAT High Density Mineral Wool and encased in polythene. The VFB Plus can be mechanically fixed both horizontally and vertically within ventilated cavities behind rainscreen or cladding systems to act as a cavity fire barrier.
The VFB Plus is a particularly versatile Ventilated Fire Barrier which can be installed in a wide range of construction types. The product is simply mechanically fixed in position to leave up to maximum 1.7″-2.1″ (44-54mm)* air gaps.
