The VFB 120/120 employs a high expansion intumescent seal fixed to TENMAT high density mineral wool. The product has undergone extensive fire testing to the general principles of BS EN1363-1 and EOTA TR31. The VFB 120/120 has also been tested to ASFP TGD19 (Fire Resistance Test for ‘Open-State’ Cavity Barriers). It is suitable for use within the majority 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 120/120 can be mechanically fixed horizontally within ventilated cavities behind external wall systems to act as a cavity fire barrier, and can be complemented by the NVFB for vertical applications.
