Intumescent Ventilation Blocks

Intumescent Air Transfer Vents

Intumescent Air Transfer Vents

When installing ventilation, air conditioning, ductwork or simply cutting holes for ventilation within a compartment wall the integrity of the building must be retained.

Fire blocks offer a low maintenance, low cost answer to this application giving up to 60 minutes* integrity in accordance to BS 476 parts 20:22 together with giving excellent free air flow during normal use.

They have no moving parts hence need no regular maintenance apart from inspection to ensure they have not been damaged.

You may also require two vent cover grilles (one for each side) to complete the installation.
