Description

This kit enables on-site assembly of fully fire tested and approved Ventilated Fire Barriers to fit all common cavity sizes with an air gap left for ventilation and moisture dissipation.

Air gaps of 25, 35 and 46mm are supported.

A roll of fire barrier material and fixings are supplied with the kit but some cavities may require mineral fibre board to narrow the cavity gap so that the activated fire seal fully closes the ventilation air gap. Mineral fibre board is sold separately.

See the Installation Guide or contact Astroflame for more details on installation options, including the use of mineral fibre boards.

Parts supplied with VFB Kit.
