Ryanmesh PF

Ryanfire Ryanmesh PF is a fire rated ventilated cavity closer designed for closiing gaps where one may have a profiled cladding installed. A lightweight, graphite infused fibreglass mesh with an added layer of Ryanfire's proprietary intumescent strap, it lies inert until exposed to fire upon which it will expand and close up the profiled cavity to prevent the spreading of fire from one floor to another. Ryanmesh PF is designed to allow the free flow of air and moisture drainage within ventilated cavity systems.
