Prevent rodents from entering buildings through cavities whilst allowing airflow and a fireproof seal. The Envirograf VWB/M Cavity Barrier with Rodent Protection has intumescent material that expands in a fire to seal gaps and ventilation holes against the spread of flames and smoke, containing a fire for extra evacuation time.

The barrier resists rodents that try to enter timber-framed buildings and cladding from the bottom edge whilst maintaining fireproof integrity.
