> Product Description

Astroflame's Astro Clad - AFFRCLADX (VFB Plus) Ventilated Fire Barriers are 'open state' cavity fire barriers for ventilated cavities of up to 450mm. Each Astro Clad - AFFRCLADX (VFB Plus) consists of a specially formulated fire rated stone mineral wool section with an integral high expansion intumescent seal fixed to the leading edge.

The Astro Clad - AFFRCLADX (VFB Plus) then leaves a maximum 44mm air gap to allow for drainage and maintain ventilation in normal use. In a fire situation the intumescent seal rapidly expands to seal off the air gap and prevent vertical fire spread within the external wall.

The product has undergone extensive fire testing following the principles of BS EN1363-1 and in accordance with ASFP TGD19 (Fire Resistance Test for ‘Open-State’ Cavity Barriers). The Astro Clad - AFFRCLADX (VFB Plus) are mechanically fixed horizontally within ventilated cavities behind the external wall substrate following the fire compartment line.

The Astro Clad - AFFRCLADX (VFB Plus) are used horizontally and can be installed in conjunction with Astroflame's Astro Clad - AFFRCLADNVFB (NVFB) Non-Ventilated Fire Barriers which provide vertical fire separation along fire compartment party wall lines.
