Introduction
RPB RG Series Intumescent Louver
There is often a requirement for a ventilation aperture to be cut into a fire resisting compartment wall or door. This penetration breaches the integrity of the element so it is necessary to fit a suitable fire resistant ventilator unit.
RESSA grille offers a specially designed solution to the problem by providing a light weight intumescent ventilator core with excellent airflow characteristics and rapid activation in the event of a fire.
